MAPEAMENTO DO LENÇOL FREÁTICO NO MUNICÍPIO DE RIO CLARO (SP) EMPREGANDO A TÉCNICA

Este trabalho mostra os resultados obtidos com ensaios geofísicos realizados no Município de Rio Claro (SP) para mapear o lençol freático e delimitar as possíveis áreas de recarga e descarga do Aqüífero Rio Claro. Para tanto, utilizou-se um grande número de ensaios geofísicos, uma vez que não seria adequado gerar um mapa potenciométrico com o pequeno número de poços existentes na área. Os ensaios geofísicos foram executados pelo método de eletrorresistividade, utilizando-se da técnica de sondagem elétrica vertical (SEV) com arranjo Schlumberger. A superfície do lençol freático, na área de estudo, constituída pela Formação Rio Claro, composta de sedimentos arenosos com intercalações de camadas centimétricas argilosas, está situado entre as cotas 566 e 669 m. O fluxo das águas subterrâneas é orientado a partir das cotas altas (norte da área) para as cotas baixas (sul e sudoeste da área) e acompanha, grosso modo, a topografia local. Palavras-chave: Geofísica Aplicada, eletrorresistividade, sondagem elétrica vertical, mapa potenciométrico, Aqüífero Rio Claro.

Variation in body size of Phanocerus clavicornis Sharp, 1882 (Coleoptera: Elmidae: Larainae) in Atlantic Rainforest streams in response to hydraulic disturbance

Neste estudo, padrões de tamanho do corpo de Phanocerus clavicornis Sharp, 1882 (Coleoptera: Elmidae: Larainae) foram investigados ao longo de um gradiente de variação de velocidade da corrente em córregos de baixa ordem da Mata Atlântica. Especificamente, buscou-se testar a hipótese de que a distribuição de larvas de P. clavicornis com diferentes tamanhos corpóreos respondem às variações na velocidade da corrente em córregos. As coletas das larvas foram realizadas com um amostrador de Surber durante dois períodos amostrais, definidos pelo regime de chuvas: agosto - estação seca e fevereiro - estação chuvosa. Possíveis diferenças nas medidas de tamanho do corpo foram testadas através de uma análise de variância (ANOVA). Os resultados daANOVAindicaram para todas as medidas das larvas coletadas nos córregos de primeira ordem (largura da cabeça, largura do protórax e comprimento total do corpo) encontramos diferenças significativas, indicando uma variação morfométrica com as mudanças das condições hidráulicas, onde as larvas menores foram associadas aos períodos de maior precipitação. No entanto, em córregos maiores (3a ordem), os eventos de chuva tiveram menor impacto no tamanho dos indivíduos, com a ocorrência de larvas com diferentes tamanhos. Os resultados deste estudo sugerem que os espaços intersticiais são importantes para a proteção das larvas contra a velocidade da corrente e que as populações de P. clavicornis possuem alta plasticidade, sendo uma característica fundamental para a ocupação desta espécie em ambientes instáveis. Esses resultados são importantes para a compreensão da história de vida e características comportamentais da espécie, que permitem persistir em córregos ao longo de gradiente de perturbação do fluxo.

Microhabitat de Tolypothrix distorta Kütz. ex Bornet & Flahault (Microchaetaceae, Cyanophyta) em dois riachos da região Centro-Sul do Estado do Paraná, Brasil

This study aimed to evaluate some microhabitat characteristics of two populations of Tolypothrix distorta in streams from midsouthern region of Paraná State on a seasonal period. Each population was monthly investigated for the abundance of T. distorta and environmental variables such as depth, current velocity, irradiance, richness, and substrate diversity (H') using the quadrat technique for each sample unit (n = 7-10). For each segment the following physical and chemical water variables were also measured: temperature, oxygen saturation, specific conductance, pH, and turbidity. The seasonal period of higher abundance (percent cover) occurred during the months corresponding to summer/fall for both populations. The analyses also showed that populations had lower niche width and wide variation under the environmental conditions, characterizing the species as a generalist in the use of resources. Faster water flow and larger substrates favored the development of T. distorta, which may be related to the species morphological characteristics, thallus type that consists of tangled filaments formed by tuft and covered with thick gelatinous coats.

A comparative evaluation of the CF:CS and CRS models in Pb-210 chronological studies applied to hydrographic basins in Brazil

The Constant Flux: Constant Sedimentation (CF:CS) and Constant Rate of Supply (CRS) of unsupported/excess Pb-210 models have been applied to a Pb-210 data set providing of eighteen sediments profiles sampled at four riverine systems occurring in Brazil, South America: Corumbatai River basin (S1=Site 1, Sao Paulo State), Atibaia River basin (S2=Site 2, Sao Paulo State), Ribeirao dos Bagres basin (S3=Site 3, Sao Paulo State) and Amazon River mouth. (S4=Site 4, Amapa State). These sites were chosen for a comparative evaluation of the performance of the CF:CS and CRS models due to their pronounced differences on the geographical location, geological context, soil composition, biodiversity, climate, rainfall, and water flow regime, among other variable aspects. However, all sediments cores exhibited a common denominator consisting on a database built from the use of the same techniques for acquiring the sediments major chemical composition (SiO2, Al2O3, Na2O, K2O, CaO, MgO, Fe2O3, MnO, P2O5, TiO2 and LOI-Loss on Ignition) and unsupported/excess 210Pb activity data. In terms of sedimentation rates, the performance of the CRS model was better than that of the CF:CS model as it yielded values more compatible with those expected from field evidences. Under the chronological point of view, the CRS model always provided ages within the permitted range of the Pb-210-method in the studied sites, whereas the CF:CS model predicted some values above 150 years. The SiO2 content decreased in accordance with the LOI increase in all cores analyzed and such inverse relationship was also tracked in the SiO2-LOI curves of historical trends. The SiO2-LOI concentration fluctuations in sites S1 and S3 also coincided with some Cu and Cr inputs in the drainage systems. (C) 2014 Elsevier Ltd. All rights reserved.

Parque Estadual da Serra do Mar, Núcleo Santa Virgínia (SP): um estudo de vazão de contribuição pelo método de regionalização hidrológica

Seeking the integrated management of water resources and financial compensation especially as a management tool, according to the Law No. 9433 of 1997 and No. 9985 of 2000. This research's main objective is measuring the flow contribution of Núcleo Santa Virginia, the State Park of Serra do Mar, starting from the hydrological regionalization method, developed by the Department of Water and Power. According to the Law 9985 of 2000 Conservation Units have the right to receive in the form of an investment a portion of the amount paid by Power Plants, being passed directly to the Conservation Units, differently from the 9433 Act. By dividing the area of Núcleo Santa Virgínia, in Sub-basins, it was possible to find the minimum flow during seven consecutive days, with a return period of ten years, Q7,10, and steady water flow in 95% of the time, Q95 for the Center and from these data to calculate the monetary value of law under Articles 47 and 48 from Law 9985 of 2000

Pluviosidade, circulação atmosférica e vazão hídrica na bacia do rio Itajaí, Santa Catarina, Brasil

This research sought to understand the temporal and spatial distribution of rainfall and its effect on water dynamics on a regional basis, taking into account the pace of climate paradigm. The study area covers the entire river basin of the Itajai and its surroundings understood, roughly, between parallels 26° and 28° south latitude and 48° and 50° 30' west longitude, place of constant heavy rains and floods. In this region, pluviometric and fluviometric data were obtained, the variables of rainfall and water flow, which were compiled and analyzed using spreadsheets in order to get the series with more homogeneous data as possible for good analysis, the period between 1953 and 1982. This historical period has passed in principle by an analysis which sought to highlight the variability and distribution of rainfall and water flow in the basin-level annual, techniques which were used that allowed the choice of standard year representative (rainy, dry , usual) series. These obtained years (1957, 1968 and 1971, respectively) underwent a detailed analysis on the monthly level, providing good interpretation of the dynamic behavior of rain associated with dynamic water flow for these representative years

Simulação numérica de fluxo de águas subterrâneas na fazenda Cara Preta - Santa Rita do Passa Quatro - SP

The term model refers to any representation of a real system. The use of models in Hydrogeology can be valuable predictive tools for management of groundwater resources. The numeric models of groundwater flow, object of this study, consist on a set of differential equations that describe the water flow in the porous medium. In this context, numeric simulations were made for a sub-basin located at Cara Preta farm – Santa Rita do Passa Quatro – SP. The aquifer at the local is composed by rocks of Pirambóia Formation, which is part of Guarani Aquifer System. It was developed a conceptual model from previous studies in the area, and from that, simulations were made through the software Visual Modflow®. The conceptual model established previously was considered consistent through the results of simulation.

Proposta de recuperação e manejo de nascente em área rural do município de Álvares Machado – SP

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
