Aplicação de modelos hidrológicos para avaliação de reservatórios de retenção e detenção combinados à obra de recuperação do canal de macrodrenagem no controle de cheias em uma bacia hidrográfica urbanizada

The aim of this paper was to evaluate the effect of retention and detention reservoirs along with the regulation in channel flow upgrade on flood for an urban watershed located at Rio Claro, SP. For this purpose, modeling and simulation techniques were applied for runoff determination and its propagation in channel. The Soil Conservation Service – SCS hydrologic model as well as Pulz and non-linear Muskingum-Cunge model were used. The software IPHS1 was applied on simulations. The results pointed out that the combination of retention increasing and detention reservoir implementation (120,000 m3, corresponding to 1.5% of the watershed area) with the streamflow upgrade (n decreasing from 0,04 to 0,02) can minimize the flood on the investigated Servidão watershed. Further, after the proposed intervention, the flood was eliminated for the investigated times of recurrence: 5, 20, 50 and 100 years. The prognostic indicated that the available area occupation had a minor effect on flow increasing due to the observed high urbanization.

HIS - Uma proposta de urbanização para o município de Santa Adélia - SP

Este trabalho apresenta uma proposta de requalificação de uma área subutilizada no município de Santa Adélia, recortada pelo córrego do Matadouro e limitada pela linha férrea. Essa área é caracterizada pela presença de grandes vazios, áreas verdes subutilizadas e precárias habitações instaladas irregularmente na nascente do córrego, às margens da linha férrea. A proposta do trabalho compreende a retirada dessas habitações subnormais, a criação de um novo parcelamento com habitações de interesse social e a criação de um grande parque urbano

Parque dos Macacos: em busca de reconhecimento e urbanidade

This paper aims to discuss the current issues involving urban water courses and, subsequently through the design of an urban park qualify the Permanent Preservation Area of the Córrego dos Macacos, locate in the city of São José do Rio Preto - São Paulo, seeking the population recognition on this living hydric resource and therefore achieve urbanity. For that purpose, we studied the urbanistic planning of the city of São José do Rio Preto regarding the proposed theme and the area of the Córrego dos Macacos valley, one of the segments of the Parque Setorial, in two previous moments as well as some key concepts, starting from a methodology of bibliographic studies analysis. After this analysis, it were determined some general guidelines for the entire extension of the stream, and finally it was chosen a specific segment to formulate proposals for a planned and design space according to the characteristics of the place

Análise da fragilidade natural do sítio urbano de Piracicaba (SP)

This research aims to analyze the natural fragility of Piracicaba Urban Site, through the analysis of a letter of Fragility Potential obtained through the data crossing the geomorphological cards, Pedologic Slope and use and occupation of the land to be developed during the project. The methodology to be used is that proposed by Ross (1990, 1994) together with the guided ideas Anthropogenic geomorphology, so that the man-made conditions of modification of the relief can be inserted in the final analyzes. The results showed that the Córrego do Enxofre Basin has high fragility of values, it is not a rich area for human occupation

Conflito de interesses ambientais: o passado, o presente e o futuro da gestão sustentávelno município de Botucatu (SP)

Entrepreneurs responsible for the housing project “Vale do Sol III”, (claim of deployment), proposed a technique, in order to resolve conflicts of interest arising in respect Vale do Sol I residents (already implemented). Conflicts taken place in accordance with environmental problems that originated (past) in poor drainage of rainwater from Água Fria stream. This work, based on study case method with deductive approach, analyzed the environmental aspects of the area in order to contribute to the process of sustainable management of medium-sized cities (present), as well as analyzing the prospects for adequate outcome environmental demand (future) . In terms of technical and methodological procedures, was used geoprocessing softwares for the purpose of supporting analysis. It was concluded that, technique proposed at Vale do Sol III enterprise, don’t have necessary, sufficient and satisfactory solution in order to, at least, mitigate the problems of area sustainability. In terms of future prospects, it was concluded that, good sustainable environmental management, with preventive measures, from the point of view of mitigating the environmental and urban conflicts, and corrective measures.

Acompanhamento da dinâmica do uso do solo em uma bacia hidrográfica no Município de Botucatu (SP) por meio de geotecnologia

The increasing expansion of agricultural activities, without considering the potential and limitations of soils is a potential source of environmental degradation. Thus, the present study assessed the variation of use and occupation in 49 years, between 1962 and 2011 scenarios of watershed of São Caetano - Botucatu (SP). geoprocessing techniques were used in this study. In a Geographic Information System (GIS) - IDRISI – it was integrated information from IBGE digital cards, scale 1:50,000, plus aerial photographs (1962) and satellite images LANDSAT - 5 (2011). In the study area, we can view the progress of the urban area, which in 1962 was not present in the watershed. In 2011, the urban area occupied 21.37% of the total area. Even with this breakthrough occurring in the period of 49 years, there was an increase in the area of natural vegetation, which once occupied only 12.33% of the area (1962), and in 2011 represents 25% of the total area of the watershed, showing an increase in awareness on the importance of preserving nature. Thus, we can conclude that the analysis tools based on GIS enabled us to analyze variations in space and time and to propose alternatives to the correct use and occupation of land.

Imagens digitais aplicadas no estudo da análise multitemporal do uso e ocupação do solo numa microbacia

The knowledge of the soil occupation as for his nature, location, occurrence form, changes happened in certain periods, they are valuable for the programming of activities that you seek to the development agricultural, economical and social of the area. This work aimed at to identify and to quantify the soil occupation of Stream Petiço Watershed - Botucatu (SP), through the Geographical Information System IDRISI and data of sensor Landsat 5 TM of 09/06/97 and 23/08/2013. For the analysis of the results it was verified that the eucalyptus culture, due to existence of great reforestation companies in the watershed, together with the native forests they are predominant in the study area, the remaining of the area is occupied by pastures and soil prepared for the planting of agricultural cultures.

Aplicação de análise multicriterial para determinação de áreas prioritárias à recomposição florestal

Using the Geographic Information System (GIS) and taking into account its capability to analyze spatial data, a database of updated spatial data from the sub-basin of the Descalvado stream, Botucatu, SP, was developed to provide an evaluation and diagnosis of the area concerning land use and the degradation processes therein. Through GIS, priority areas for forest recovery were defined by Multicriteria Evaluation and using the Ordered Weighted Average method. The latter allows the decision maker to define the area to be recovered, facing limitation of resources, among one of the proposed scenarios, or do it in stages. The study showed that there are accelerated erosion processes in the headwaters of the springs of water bodies; there is also fragmentation of native vegetation, especially in hillside areas, and little presence of native vegetation in riparian areas. The application of the multicriteria analysis using the Ordered Weighted Average was important as it systematized and discriminated scenarios of priority for forest recovery.
