Hydraulic and fluvial geomorphological models for a bedrock channel reach of the Twenty Mile Creek /

Bedrock channels have been considered challenging geomorphic settings for the application of numerical models. Bedrock fluvial systems exhibit boundaries that are typically less mobile than alluvial systems, yet they are still dynamic systems with a high degree of spatial and temporal variability. To understand the variability of fluvial systems, numerical models have been developed to quantify flow magnitudes and patterns as the driving force for geomorphic change. Two types of numerical model were assessed for their efficacy in examining the bedrock channel system consisting of a high gradient portion of the Twenty Mile Creek in the Niagara Region of Ontario, Canada. A one-dimensional (1-D) flow model that utilizes energy equations, HEC RAS, was used to determine velocity distributions through the study reach for the mean annual flood (MAF), the 100-year return flood and the 1,000-year return flood. A two-dimensional (2-D) flow model that makes use of Navier-Stokes equations, RMA2, was created with the same objectives. The 2-D modeling effort was not successful due to the spatial complexity of the system (high slope and high variance). The successful 1 -D model runs were further extended using very high resolution geospatial interpolations inherent to the HEC RAS extension, HEC geoRAS. The modeled velocity data then formed the basis for the creation of a geomorphological analysis that focused upon large particles (boulders) and the forces needed to mobilize them. Several existing boulders were examined by collecting detailed measurements to derive three-dimensional physical models for the application of fluid and solid mechanics to predict movement in the study reach. An imaginary unit cuboid (1 metre by 1 metre by 1 metre) boulder was also envisioned to determine the general propensity for the movement of such a boulder through the bedrock system. The efforts and findings of this study provide a standardized means for the assessment of large particle movement in a bedrock fluvial system. Further efforts may expand upon this standardization by modeling differing boulder configurations (platy boulders, etc.) at a high level of resolution.

Second Welland Canal - Book 2, Survey Map 17 - Deep Cut and Port Robinson

Survey map of the Second Welland Canal created by the Welland Canal Company showing the canal at Port Robinson. Identified structures and features associated with the Canal include the Deep Cut, Old Channel of Canal, and the towing path. The surveyors' measurements and notes can be seen in red and black ink and pencil. Local area landmarks are also identified and include streets and roads (ex. Road to Port Allanburg), the Spoil Bank, an island, several bridges, and a church. Several unidentified structures are present but not labeled. Properties and property owners of note are: Lots 202, 203, and 204. Lot 203 is divided into several properties labeled A - J. Owners of these properties include James McCoppen, John Coulter, James Griffith, John C. Jordan, W. Hendershot, John Greer, Charles Richards, C. Stuart, and S. D. Woodruff. Other property owners include D. McFarland.

Niagara Suspension Bridge Bank note, 1841

The Niagara Suspension Bridge Bank operated in Queenston in 1840. The bank issued notes in denominations of ten dollars, five dollars and one dollar, and featured a drawing of the Queenston-Lewiston Bridge, ten years prior to its construction. The notes are signed by the bank’s Cashier, Gilbert McMicken, and President, Joseph Hamilton. The bank failed a year after its establishment.

Bank of Canada Records, 1958-1989

The Bank of Canada first introduced Canada Savings Bonds during the First and Second World Wars. At the time, they were known as War Savings Certificates and Victory Bonds and were used to fund the war effort. In 1946, Canada Savings Bonds were used as part of Canada’s Postwar Financing Program. At that time, the government also introduced the sale of bonds through payroll deduction. Canada Savings Bonds proved to be very popular, providing investors with a convenient, flexible and safe investment. Over time the bonds failed to remain competitive with other low-risk investment options, and the high cost of administering the program called into question its relevance. An independent report commissioned by the government in 2004 recommended that the bonds be phased out, however, the government decided to keep the program and make some revisions. As of 2012, Canada Savings Bonds are available exclusively through the payroll savings program, while Canada Premium Bonds (introduced in 1998) are available through financial institutions, dealers and by phone.

Royal Bank of Canada records, 1973-1977

In 1973, the Royal Bank of Canada began construction on a new office in downtown Toronto known as the Royal Bank Plaza. The $100 million construction project consisted of two triangular office towers linked by a glass-enclosed banking hall. In addition to housing the Royal Bank of Canada’s Ontario headquarters, the Plaza included a two-level shopping concourse with restaurants and boutiques, as well as office space available for lease. The Plaza officially opened on March 10, 1977.
