Historical Development and Applications of the EPIC and APEX Models, June 2005

The development of the field-scale Erosion Productivity Impact Calculator (EPIC) model was initiated in 1981 to support assessments of soil erosion impacts on soil productivity for soil, climate, and cropping conditions representative of a broad spectrum of U.S. agricultural production regions. The first major application of EPIC was a national analysis performed in support of the 1985 Resources Conservation Act (RCA) assessment. The model has continuously evolved since that time and has been applied for a wide range of field, regional, and national studies both in the U.S. and in other countries. The range of EPIC applications has also expanded greatly over that time, including studies of (1) surface runoff and leaching estimates of nitrogen and phosphorus losses from fertilizer and manure applications, (2) leaching and runoff from simulated pesticide applications, (3) soil erosion losses from wind erosion, (4) climate change impacts on crop yield and erosion, and (5) soil carbon sequestration assessments. The EPIC acronym now stands for Erosion Policy Impact Climate, to reflect the greater diversity of problems to which the model is currently applied. The Agricultural Policy EXtender (APEX) model is essentially a multi-field version of EPIC that was developed in the late 1990s to address environmental problems associated with livestock and other agricultural production systems on a whole-farm or small watershed basis. The APEX model also continues to evolve and to be utilized for a wide variety of environmental assessments. The historical development for both models will be presented, as well as example applications on several different scales.

Identification of the Best Practices for Design, Construction, and Repair of Bridge Approches, 2005

Bridge approach settlement and the formation of the bump is a common problem in Iowa that draws upon considerable resources for maintenance and creates a negative perception in the minds of transportation users. This research study was undertaken to investigate bridge approach problems and develop new concepts for design, construction, and maintenance that will reduce this costly problem. As a result of the research described in this report, the following changes are suggested for implementation on a pilot test basis: • Use porous backfill behind the abutment and/or geocomposite drainage systems to improve drainage capacity and reduce erosion around the abutment. • On a pilot basis, connect the approach slab to the bridge abutment. Change the expansion joint at the bridge to a construction joint of 2 inch. Use a more effective joint sealing system at the CF joint. Change the abutment wall rebar from #5 to #7 for non-integral abutments. • For bridges with soft foundation or embankment soils, implement practices of better compaction, preloading, ground improvement, soil removal and replacement, or soil reinforcement that reduce time-dependent post construction settlements.

Development of the Iowa Drainage Law Manual, March 2005

Although Iowa has some of the most productive agricultural land in the nation, it also maintains a very extensive road network.Consequently, landowners and roadway officials often must deal with drainage issues affecting private lands and public highways. However, many individuals are unfamiliar with legal drainage requirements, practices, and procedures, which can result in misunderstandings concerning maintenance responsibilities for drainage facilities, sometimes leading to litigation. To assist propertyowners, public agencies, and others with interest in better understanding drainage maintenance responsibilities, a reference manual was developed to describe Iowa’s drainage laws and offer interpretations in a clear and concise manner. To develop a comprehensive drainage manual, researchers identified and reviewed current available literature. These resources described pertinent drainage issues and presented explanations of legal responsibilities. The literature review included manuals and guides from Iowa, surrounding states, and federal agencies. Researchers developed a survey to assess the needs and interestsof potential users of an Iowa drainage law manual. Survey responses were used to identify common problems and concerns among individuals who encounter drainage issues on a regular basis. Issues mentioned in the survey responses included interpretation of drainage laws and commonly encountered questions relating to public improvements and private interests. Many individuals, including county engineers, stated interest in specific topics such as maintenance and/or diversion of drainage, landowner issues, and upstream and downstream impacts. Overall, the survey provided researchers with valuable information regarding drainage issues, problems, current policies, and concerns. A comprehensive manual of Iowa drainage law will assist agencies and individuals in interpreting current code requirements and in implementing effective and beneficial solutions when dealing with drainage issues.

Integrated Materials and Construction Practice for Concrete Pavement: A State-of-the-Practice Manual, 2006

At the heart of all concrete pavement projects is the concrete itself. This manual is intended as both a training tool and a reference to help concrete paving engineers, quality control personnel, specifiers, contractors, suppliers, technicians, and tradespeople bridge the gap between recent research and practice regarding optimizing the performance of concrete for pavements. Specifically, it will help readers do the following:

Validation of the New Mix Design Process for Cold In-Place Rehabilitation Using Foamed Asphalt, 2007

Asphalt pavement recycling has grown dramatically over the last few years as a viable technology to rehabilitate existing asphalt pavements. Iowa's current Cold In-place Recycling (CIR) practice utilizes a generic recipe specification to define the characteristics of the CIR mixture. As CIR continues to evolve, the desire to place CIR mixture with specific engineering properties requires the use of a mix design process. A new mix design procedure was developed for Cold In-place Recycling using foamed asphalt (CIR-foam) in consideration of its predicted field performance. The new laboratory mix design process was validated against various Reclaimed Asphalt Pavement (RAP) materials to determine its consistency over a wide range of RAP materials available throughout Iowa. The performance tests, which include dynamic modulus test, dynamic creep test and raveling test, were conducted to evaluate the consistency of a new CIR-foam mix design process to ensure reliable mixture performance over a wide range of traffic and climatic conditions. The “lab designed” CIR will allow the pavement designer to take the properties of the CIR into account when determining the overlay thickness.

Office of the State Long-Term Care Ombudsman Annual Report 2004, January 2005.

The State Long-Term Care Ombudsman program operates as a unit within the Office of Elder Rights at Iowa Department of Elder Affairs. Duties of all long-term care ombudsmen are mandated by the Older Americans Act. This office serves people living in nursing facilities, residential care facilities, elder group homes and assisted living programs. Iowa’s State Long-Term Care Ombudsman’s Office has gone through many changes this past year ranging from staff changes to increase in jurisdiction area. Jeanne Yordi is now the State Long-Term Care Ombudsman, joining this promotion, will be three additional Long-Term Care Ombudsmen to the unit. With additional staff this office hopes to create more public awareness; however, cases and complaints are top priority as this office may begin to fulfill the mandates of the Older Americans Act.

Condition of the State of Iowa, 2009.

A transcript of the Condition of the State of Iowa speech by Governor Chet Culver delivered at the State Capitol on January 13, 2009. The governor spoke about the difficulties of the past year in Iowa; tornados, flooding, and economic woes. He also spoke about how the state will overcome the obstacles before it and the basic ideas for his upcomming budgetary decisions.

The State of the Judiciary, 2009

Thank you for inviting me again this year to talk with you about the condition of Iowa’s judicial branch. As your partner in government, we look forward to working with you on issues affecting the administration of justice. If I could capture the condition of our courts, indeed the condition of our state, in a few words, it would be: “We live in challenging times.” No one knows the true meaning of this phrase better than those Iowans hit by natural disasters. But my focus today is, of course, on the courts. Ensuring the delivery of equal, affordable and accessible justice is always challenging work, but it will be especially so this year and the next in light of the State’s budget problems. Given the magnitude of this challenge, it is even more imperative that we work together in the spirit of unity, candor and cooperation. And I address you today in this spirit. We are deeply concerned, as you are, about the present financial situation and its effect on individual Iowans. Naturally, we are particularly troubled about its impact on the delivery of justice to our citizens. Even in good economic times, the administration of justice is difficult to fulfill given the sheer volume and complexity of problems Iowans bring to their courthouses. Because of the effects of the nation’s economic downturn, people will need access to justice now more than ever. We already see this happening. The number of mortgage foreclosure cases in Iowa rose 14% in the past year. Debt collection cases increased 20% in the same time. An increase in these types of cases is predictable in tough economic times, but other types of problems may escalate as well. Some experts fear that a recession may also give rise to more crime, child abuse, domestic violence, and substance abuse. Naturally, for the sake of the people who may be harmed by these problems, we hope they do not occur. If they do, however, these matters will demand our immediate attention.

Annual Report of the Iowa Grape and Wine Development Commission for Fiscal Year, 2007

FY2007 was a productive year for the Iowa Grape and Wine Development Commission. Fourteen proposals were recommended for funding totaling over $390,000 in outlays. Included in the approved proposals were funds for the establishment and staffing of a Midwest Grape and Wine Institute at Iowa State University, a newly created viticulturist position at Des Moines Area Community College, funding for the first annual Mid-American Wine Competition, and marketing and promotion of four regional cooperative wine events and one wine trail. Commission funding supported a survey of commercial wine producers and grape growers and a new brochure on Iowa’s vineyards. A committee was formed to provide details for a Scholarship Program to aid vineyard and winery staff with the expenses of accredited coursework. Based on the survey conducted and from other governmental and industry sources, the Iowa grape and wine industry appears to continue to be very viable and growth continues at a strong pace. Wine produced in the state for 2007 was estimated at a market value in excess of $12.3 million. A tabulation of the budget revealed that just over $800,000 in wine gallonage tax appropriations have been received into the Grape and Wine Development Fund from 15 FY2003 through FY2007. Expenditures have totaled just over $607,000 during that same time. Just over 80% of expenditures have gone to “Technical” spending. Over time, funds invested in “Technical” programs will translate into an increasingly educated and institutionally-supported industry. Local, regional, and statewide events also appear to be increasing in popularity and the Commission plans to continue and increase support for these events. It is hoped the Scholarship Program will be up and running and funding will need to be appropriated for that project. The Commission also believes many projects and events will become more and more self sustaining as they develop and mature. As they continue to support Iowa’s grape and wine industry, the members of the Commission look forward to working with individuals, commercial enterprises, state and federal agencies, and industry-sponsored institutions in the upcoming year and in years to come.

Annual Report of the Iowa Grape and Wine Development Commission for Fiscal Year, 2008

FY2008 was a productive year for the Iowa Grape and Wine Development Commission. Sixteen proposals were recommended for funding from FY2008 funds and carryover totaling just over $396,000 in outlays. Included in the approved proposals were staffing and equipment for the Midwest Grape and Wine Industry Institute’s wine diagnostics laboratory at Iowa State University, continued support for the viticulturist position at Des Moines Area Community College, funding for the second annual Mid-American Wine Competition, and assistance for marketing and promotion of Ice coats an Iowa vineyard after a February 2008 ice storm. Photo by Mike White and courtesy of Iowa State University. 16 two wine trail associations and seven festivals and events. Commission funding supported a salaried position within IDALS to manage the Iowa Grape and Wine Development Fund and to serve as the Director of the Iowa Grape and Wine Development Commission. The Commission approved funding for a Scholarship Program. The formally created Scholarship Committee met twice in FY2008 to finalize details for the Program and to approve scholarships to twenty-six applicants to aid with the expenses of accredited coursework. Based on data collected by IDALS, the Iowa Department of Economic Development, the Iowa Alcoholic Beverages Division, and Iowa State University the Iowa grape and wine industry appears to continue to be very viable and growth continues at a strong pace. Presently, Iowa ranks 14th in the nation for the number of wineries, and wine produced in the state for 2008 was estimated at a market value in excess of $14.0 million. A tabulation of the budget revealed that just over $1,080,000 in wine gallonage tax appropriations and legislative appropriations have been deposited into the Grape and Wine Development Fund from FY2003 through FY2008. Removing encumbered funds, expenditures have totaled just over $942,500 during that same time. “Financial” funding – used for fostering public awareness and participation of industry events - increased from 6% of expenditures in FY2007 to 9% in FY2008. Used for support of research, education, and outreach, a little over 80% of expenditures and encumbered funds were earmarked for “Technical” spending. Over time, funds invested in “Technical” programs will translate into an increasingly educated and institutionally-supported industry. Local, regional, and statewide events also appeared to be increasing in popularity. The Commission was encouraged to see increased support for these events. It is hoped, too, that the Scholarship Program will provide needed funding to help meet the educational goals of the industry’s workforce. As they continue to support Iowa’s grape and wine industry, the Commissioners look forward to working with individuals, commercial enterprises, state and federal agencies, and industry-sponsored institutions in FY2009 and in years to come.

Hydrologic Simulations of the Maquoketa River Watershed Using SWAT Working Paper 09-WP 49,June 2009

This paper describes the application of the Soil and Water Assessment Tool (SWAT) model to the Maquoketa River watershed, located in northeast Iowa. The inputs to the model were obtained from the Environmental Protection Agency’s geographic information/database system called Better Assessment Science Integrating Point and Nonpoint Sources (BASINS). Climatic data from six weather stations located in and around the watershed, and measured streamflow data from a U.S. Geological Survey gage station at the watershed outlet were used in the sensitivity analysis of SWAT model parameters as well as its calibration and validation for watershed hydrology and streamflow. A sensitivity analysis was performed using an influence coefficient method to evaluate surface runoff and base flow variations in response to changes in model input hydrologic parameters. The curve number, evaporation compensation factor, and soil available water capacity were found to be the most sensitive parameters among eight selected parameters when applying SWAT to the Maquoketa River watershed. Model calibration, facilitated by the sensitivity analysis, was performed for the period 1988 through 1993, and validation was performed for 1982 through 1987. The model performance was evaluated by well-established statistical methods and was found to explain at least 86% and 69% of the variability in the measured stream flow data for the calibration and validation periods, respectively. This initial hydrologic modeling analysis will facilitate future applications of SWAT to the Maquoketa River watershed for various watershed analysis, including water quality.

Correlation of the IJK Roadmeter to the International Roughness Index, MLR-91-5, 1992

The Iowa Department of Transportation has been determining a present serviceability index (PSI) on the primary highway system since 1968. A CHLOE profilometer has been used as the standard for calibrating the Roadmeters that do the system survey. The current Roadmeter, an IJK Iowa DOT developed unit, is not considered an acceptable Roadmeter for determining the FHWA required International Roughness Index (IRI). Iowa purchased a commercial version of the South Dakota type profile (SD Unit) to obtain IRI. This study was undertaken to correlate the IRI to the IJK Roadmeter and retire the Roadmeter. One hundred forty-seven pavement management sections (IPMS) were tested in June and July 1991 with both units. Correlation coefficients and standard error of estimates were: r' Std. Error PCC pavements 0.81 0.15 Composite pavements 0.71 0.18 ACC pavements 0.77 0.17 The correlation equations developed from this work will allow use of the IRI to predict the IJK Roadmeter response with sufficient accuracy. Trend analysis should also not be affected.
