This study aimed to simulate and evaluate the sediment transport in Upper Basin Stream Cachoeirinha in Rio Claro, SP, and compare the results with previous studies performed in the same basin. The modeling software used in this study was Soil and Water Assessment Tool (SWAT), which is a very comprehensive tool that discusses many physical processes. In this work, the hydrosedimentological processes were treated, aiming to understand the sediment production and transport. The Basin Stream Cachoeirinha has an area with predominantly agricultural use, especially sugar cane. The database for inclusion in software was constructed from the following elements: climatic, topographical, soil type and use and land cover of the area, also including the parameters of Modified Universal Soil Loss Equation (MUSLE). The analysis was conducted for a period of 16 years (1994-2010), which is the range of data available from CEAPLA. The results were analyzed in terms of annual runoff and sediment yield. The average sediment delivery in the simulation was 0.94 t/ha/year, while the maximum annual contribution was 7.28 t/ha/year

With the accelerated urbanization process of Brazil from the 50s, there was a disorderly occupation of spaces and consequent soil sealing. Unlike this growth, the support capacity of urban environments has not evolved in the same way, generating negative environmental impacts to the citizens. Among these impacts are the effects of flooding. In order to minimize the negative effects of extreme precipitation over cities, the government invests in corrective measures, like compensatory techniques on urban drainage, which have as a basic principle the retention and infiltration of the rainfall, dampening the peak flow and runoff. An example of applying these techniques in urban areas are the detention basins, commonly called large pools. The hydraulic design of these structures is dependent of complex data and variables, and projects involving small areas generally use simplified methods for defining the reservoirs volume of the storage (Tassi, 2005). One of these methods is presented in this study, which relates to the percentage of soil sealing to the specific storage volume (m³/ha) in combination by applying the hydrological model of the Rational Method and analyzing regional rainfall and soil occupation over the basin. Within this context, the basin of the Wenzel stream, which is located amidst the urban area of Rio Claro/SP, also presents the problems related to human occupation in its valley. Thus, by the method presented has been adjusted a curve correlating the percentage of impermeable area and the specific volume of a detention basin. For the current situation of Wenzel Basin with 82% of impermeable area, and return period of 10 years, the specific volume is 262.1 m³/ha. The presented method is consistent with the results of other studies in the area, and the expression obtained allows estimating the volume of storage required to match hydrograph pre and post-occupancy. It presents itself as a useful tool in the planning stage of...

This paper focuses on the implementation of a geological and geotechnical mapping to the planning of the region stream Bertini, territorial expansion area of the municipality of Americana (SP), a medium-sized city in the countryside of Sao Paulo state, with great potential for growth industrial and residential. To this end, based on the methodology established by the Institute for Technological Research, the charters geological and geotechnical aimed at exposing the capabilities and limitations of the soil. The analysis of similar soil characteristics such as geology, geomorphology, slope, geotechnical testing and the current use and land cover was possible to recognize four geotechinical units. The units I and III are related to areas of top and concave and convex parts of the study area, shown to be sites of low occupancy restriction. However the units II and IV, respectively allocated in the floodplain of the Piracicaba River and the banks of the stream Bertini and some of its drainage, showed a more restricted area due to proximity to water bodies and drainages that offer higher slopes.

O município de Franca-SP situa-se na Província Geomorfológica das Cuestas Basálticas no nordeste paulista, a qual possui características ambientais próprias. De uma forma geral, a região de Franca enfrenta problemas ambientais como a suscetibilidade à erosão linear e laminar, aos movimentos de massa e ao assoreamento dos canais de drenagem. Estes problemas, por sua vez, induzem a situações socioeconômicas, como o incremento da pobreza, aglomeração urbana e, uma emergente demanda da sociedade por mudanças no âmbito da gestão local. Assim, devem ser efetuados estudos detalhados sobre o meio, a fim de minimizar e/ou evitar tais problemas. Desta forma, propos-se a realização do Zoneamento Geoambiental, o que implica no levantamento, análise, interpretação e correlação dos diferentes componentes ambientais, visando dar subsídio a órgãos públicos e proprietários rurais, tanto na fase de planejamento como na implantação de culturas agrícolas, pecuária, reflorestamento e uso da água superficial (lençol freático), de maneira racional e ambientalmente sustentável, garantindo assim a ocupação adequada do solo e a melhor conservação dos recursos naturais. O trabalho iniciou-se com a organização e reinterpretação dos dados pré-existentes (topográficos, geológicos, pedológicos, geomorfológicos, morfoestruturais, de coberturas de alteração intempérica e sócio-econômicos) e geração e/ou reorganização de novos dados e propostas para a minimização dos impactos sócio-ambientais (rede de drenagem, hipsométricos, morfométricos, tectônicos, geológicos, geomorfológicos, climáticos e bióticos) com a utilização de técnicas de fotointerpretação de diversos sensores remotos e de campo. Deste modo, a correlação de todas as informações geoambientais relativas ao município proporcionou a delimitação das suas zonas e subzonas geoambientais...

Pipelines are linear engineering works, designed mostly for transporting oil and its derivatives for long distances, furnishing even the farthermost zones of the country. Due to oil sector needs to ensure for the safety and conservation of its properties, several geotechnical studies are being held at the pipelines field, in order to preserve this important transportation, and also to prevent accidents, which might seriously compromise the environment and the population who lives around it. The OSBRA pipeline, who connects the city of Paulínia to the capital Brasília, is one of these engineering works that deserves to be pointed out. This research, performed at the Ribeirão da Prata Basin, was a pilot study conducted with the main objective of testing the current methodology efficiency, for future applications in the closest watersheds to the OSBRA pipeline. The objective of this research is to analyze flood wave and debris flow processes in a non-fictional watershed, by comparing two different kinds of methods: the first one based on simulation models (software ‘ABC 6’), and the other one by flood wave and debris flow susceptibility mapping. The results from the hydrological modeling were both hydrographs and ietographs that estimated values of outputs and infiltration. To construct the susceptibility maps were necessary three other maps: ground use and occupation maps, divided according to the different protection degrees that were offered to the ground; maps of dam locations in the area and physiographic compartimentation maps, divided according to the local geology. To complete the methodology, the results were collected from both methods for comparison. The obtained product for this methodology was series of data whose different susceptibility degrees to flood wave and debris flow could define the safest route for a pipeline crossing in this watershed...

As an effect of the imbalance caused by the damming of rivers and pollution, it has been observed a growing aquatic plants infestation in reservoirs for the generation of electricity. In addition to power generation, these sites have also been used for various other purposes, including recreation, attracting water and navigation. Thus it is important to evaluate these water bodies periodically, in order to verify the leading conditions to the growth of algae, plants and other organisms. In this sense, Remote sensing technology can be a valuable tool for mapping and monitoring the occupation of land in the vicinity of the water body and the optical properties of water, to provide subsidies for the effective management of these aquatic environments. This paper aims to perform the monitoring of the occurrence of aquatic plants in Salto Grande Hydropower Reservoir, located in Americana (SP) and, periodically, map the occupation of land in the vicinity of the water body, through multispectral images taken by sensors on the satellites Landsat series in seven consecutive years: 2004, 2005, 2006, 2007, 2008, 2009 and 2010. The adopted methodological procedure included the images data and the classification of multispectral images to map, every year, the location and extension of the area infested by aquatic plants and the occupation of land

Os eventos extremos pluviométricos quando ocorrem em cidades sem um prévio planejamento capaz de suportar tais episódios, trazem certo desconforto para a população e seu habitual modo de vida. Os impactos registrados nos ambientes urbanos estão associados, na maioria das vezes, à inadequação do uso e ocupação do solo urbano. Assim, através deste estudo buscou-se analisar os impactos deflagrados por eventos de precipitação na cidade de Presidente Prudente, baseando-se principalmente no referencial teórico-metodológico Sistema Clima Urbano, em especial, no Subsistema Hidrodinâmico, proposto por Monteiro (1976). Assim, procurou-se analisar os transtornos que ocorreram na dinâmica socioambiental da cidade durante os eventos de precipitação mais expressivos. Para isto foram analisados os dados quantitativos da Estação Meteorológica da FCT/UNESP de Presidente Prudente e também dados qualitativos por meio dos registros dos jornais da cidade. Para as análises quantitativas foram utilizados os dados da estação meteorológica do período de 1969 a 2009, e para as análises qualitativas foi considerado este mesmo período. Através desse estudo, foi possível conhecer e estudar a distribuição espacial dos problemas sociais e ambientais deflagrados pela precipitação no ambiente urbano de Presidente Prudente e também entender a dinâmica desses impactos. Portanto, com este estudo pretende-se contribuir com os órgãos públicos de gestão urbana para que eles possam tomar medidas preventivas para diminuir os impactos em época de chuvas intensas, visando assim, à melhoria da qualidade de vida

The lack of proper planning in intervention works of runoff water on rural properties and rural public roads leads to economic damage and loss of environmental quality. The impact of the action without technical base is soil erosion, siltation of water sources, loss of the quality and availability of water, invalidating areas for cultivation and livestock. The conservation of headwaters requires beyond regeneration of the environmental characteristics the repair and management of the degraded watercourse in order to control erosion. This graduate work in Environmental Engineering from Universidade Estadual Paulista Julio de Mesquita Filho - UNESP Presidente Prudente proposes a headwater recuperation and management in rural area of Álvares Machado municipality, São Paulo State, through the method of deep drainage applied to the case of a rural road near the outcrop of water. This technique consists in the installation of draining structures in sub-areas of the road surface, or sub-gutter and/or in the platform border in order to conduct the underground flow of water and reduce the loss of sediment in water flow. Therefore, was performed a historic study of use and occupation of land in the municipality of Álvares Machado, portraying transformations of the landscape caused by human action. Geology, geomorphology, pedology and hydrogeology data were collected from the study area in order to establish the conditions that led into the current situation of degradation and formulate an effective intervention strategy for civil works

In most brazilian cities, urban growth has occurred without adequate planning. Consequently, portions of the city were being occupied, often areas unfit for use and occupation of land, causing risks to local residents and decline of urban environmental quality. One of the most frequent problems is the riverbank occupation, causing the deforestation of the riparian vegetation. Given the above, this paper aimed to map the urban sprawl of Rio Claro/SP, as well as riparian vegetation in the vicinity of Corumbataí in the area including the urban area. For this purpose, GIS techniques were used in order to prepare the thematic map of urban expansion, as well as a map of the riparian vegetation through interpretation of aerial photographs in the environment of ARCGIS. From the maps, an analysis of “Plano Diretor” was made in order to verify if the current occupation of urban land meets the stipulations of this legal instrument

O cerrado é o segundo bioma mais representativo do Brasil, correspondendo a 23% do território brasileiro. É considerado um hotspot de biodiversidade, apresentando-se bastante ameaçado. Sua devastação é devido, principalmente, ao avanço das culturas agroindustriais de grande mercado. Sabe-se da importância da polinização para a reprodução de inúmeras espécies vegetais. Neste contexto, as abelhas desempenham um papel fundamental devido à sua dependência e especialização na coleta de recursos florais. Mas, estas também requerem locais propícios à nidificação. Além da destruição do hábitat através da fragmentação, a composição da paisagem que permeia fragmentos de vegetação nativa pode influenciar a diversidade apícola e afetar de forma diferente as espécies de acordo com seu hábito de nidificação e alimentação. É fato que as espécies mais especializadas tornam-se mais vulneráveis às alterações ambientais por apresentarem exigências particulares e pouca plasticidade na obtenção de recursos. A fim de analisar a interação entre diversidade de abelhas e Ecologia da Paisagem, foram selecionados dois levantamentos de fauna apícola (Itirapina – SP e Pirassununga – SP). Para isso foram elaborados mapas de uso e ocupação do solo através do SPRING 5.1.7 e, posteriormente, gerados os índices de Ecologia de Paisagens selecionados para o estudo com o auxilio do aplicativo FRAGSTATS 2.0. As espécies coletadas em ambas as áreas foram separadas em guildas funcionais de forrageamento e nidificação. A área de estudo de Itirapina foi sub-dividida em 13 classes de uso e ocupação da paisagem e a área de estudo de Pirassununga foi sub-dividida em 7 classes, conforme as características presentes em cada área. Entretanto, foi dado destaque às três principais classes de estudo: remanescentes florestais, uso antrópico e água para Itirapina... (Resumo completo, clicar acesso eletrônico abaixo)

The assessment of land use dynamic can be an instrument for analysis in anthropogeomorphology, which would allow one to verify the human geomorphological actions and its various implications in changing the original morphology for the creation of a human morphology. This study aimed to consider the land use dynamics and its interference in the morphology of Cavalheiro Stream Basin. From this assessment, to understand the implications of land use in the creation of a human morphology, as well as to analyze if the current use is in accordance with the legal restrictions placed by ongoing environmental legislation and with the ability to land use. The chosen of this studied area was due to assumptions raised by Pinton (2007) for changes in the dynamic of rainwater erosion of this area caused by human actions, specially the cultivation of sugar cane in morphologies that are unfit for it. The search took as methodological support the principles that concern the General Systems Theory, trying to see the watershed as an open system. The geomorphological data, of land use and of legal restrictions to the use and occupation of land, were collected from different cartographic techniques. Besides, it was developed a sketch map of land use capacity by adapting the technique proposed by Lepsch (1983). This way, the data obtained in this survey are considered capable to provide subsidies for the identification of changes in original morphology of the Cavalheiro Stream Basin and the genesis of a human morphology, as well as conflicts and adjustments of current land use in environmental system and on the legal restrictions outlined in the ongoing environmental legislation, contributing to a proper environmental planning with the characteristics of the physical environmental system of this basin
