Importantes características de chuva para a conservação do solo e da água no município de São Manuel (SP)

Os modelos matemáticos preditivos da erosão do solo, como a Equação Universal de Perda de Solo (EUPS), são de muita valia no planejamento de uso agrícola da terra. Tal equação, desenvolvida para estimar as perdas médias anuais de solo esperadas em dado local, para determinado sistema de manejo, apresenta como variáveis os fatores erosividade da chuva (R), erodibilidade do solo (K), comprimento do declive (L), grau do declive (S), cobertura e manejo (C) e práticas conservacionistas de suporte (P). Com o objetivo de contribuir para o planejamento conservacionista de uso do solo local, foi estimado, de forma simplificada, o fator erosividade da chuva (R) da EUPS para o município de São Manuel (SP), para uma série pluviométrica contínua de 49 anos de dados de chuva diária. Além disso, foram também calculados o período de retorno, a freqüência de ocorrência dos índices de erosividade anuais e as quantidades máximas diárias das chuvas necessárias para o dimensionamento mais adequado de canais de terraços agrícolas em nível. O valor calculado do fator R foi de 7.487 MJ mm ha-1 h-1 ano-1, esperado ocorrer no local, pelo menos, uma vez a cada 2,33 anos, com uma probabilidade de 42,92 %. Observou-se uma concentração de 81,48 % do valor total deste fator no semestre de outubro a março, indicando que, potencialmente, as maiores perdas anuais de solo por erosão são esperadas neste período. Os valores anuais do índice EI30, esperados para os períodos de retorno de 2, 5, 10, 20, 50 e 100 anos, foram de 7.216, 8.675, 9.641, 10.568, 11.768 e 12.667 MJ mm ha-1 h-1 ano-1, respectivamente. Com relação às quantidades máximas de chuva diária, para os mesmos períodos de retorno, os valores foram de 73, 98, 115, 131, 151 e 167 mm, respectivamente.

Classificação climática para os municípios de Botucatu e São Manuel, SP

Climatic classification defines the geographical limits of different climate types all over the world, and it is considered essential to study similar areas. This work updates the climatic classification of the municipal districts of Botucatu and of São Manuel, State of Sao Paulo, where the experimental farms of the Schools of Agronomical Sciences - UNESP, Campus of Botucatu, State of São Paulo, are located. Koppen's and Thornthwaite's methods were used for the air temperature and precipitation data, in a 36-year period (from 1971 to 2006). For both municipal districts of Botucatu and São Manuel, the climate was characterized as being Cfa, hot climate with rains in the summer and drought in the winter, and the average temperature in the hottest month is above 22 °C. According to Thornthwaite's classification, there was a small difference due to the humidity index, characterized as B2rB′3a′ (humid climate with small hydro deficiency - April, July and August, with annual potential evapotranspiration of 945.15 mm and concentration of the potential evapotranspiration in the summer of 33%) in the district of Botucatu, and as B1rB′3a′ (humid climate with small hidric deficiency - April, July and August, with annual potential evapotranspiration of 994.21 mm and concentration of the potential evapotranspiration in the summer of 33%)in the district of São Manuel.

Diagnóstico ambiental em área com vazamento de combustíveis por meio da integração de dados geofísicos e geoquímicos no município de São Manuel - SP

The contamination of the physical environment occurs as a result of the lack of planning and inadequate management of hazardous products. Due to the difficulty of the characterization and study of soil and groundwater, the contamination has been long neglected. The characterization of these areas by research techniques through direct methods such as physical and chemical analysis, are widely used in the diagnosis and monitoring. However, despite presenting quantitative results, this method is not representative in spatial terms. The purpose of this work is to bring geophysical complementation with the diagnosis, bringing the spatial element for the detection of the contamination plume. In the study area, there was a railway accident in 1999 in which three wagons fell and spilled 240,000 L of diesel onto the soil. The main objective is to assess the presence of contaminants in the residual phase and dissolved in the subsurface, using the technique of Electrical Tomography (ETR), understand the effects of natural attenuation process in the degradation of hydrocarbons and changes in electrical properties in soil and groundwater. The results allowed the definition of three distinct patterns of resistivity region with presence of dissolved phase, set in a historical chemical analyzes: low values (> 60Ω.m) associated with the presence of hydrocarbons in an advanced stage of degradation, intermediate values (260Ω.me 511Ω .m) indicative of coexistence of residual hydrocarbons and dissolved phase, and high values (> 1000Ω.m), which reveal the prevalence of residual phase with incipient degradation, possibly in high toxicity concentrations for effective action of biodegradation processes. The diagnostic of areas with potential accumulation of residual phase can subsidize the planning of remediation techniques and promote the complete decontamination of the area

Utilização de imagem de satélite Landsat no mapeamento da ocupação da terra e seus conflitos de uso em APPs na bacia hidrográfica do ribeirão Paraíso - São Manuel (SP)

The objectives of this study were to evaluate land use and occupation of Permanent Preservation Areas (PPA) as well as its use conflicts by TM (Thematic Mapper) image of the 2010 Landsat-5 satellite, according to the Forest Code. For that purpose, Geographic Information Systems in the Ribeirão Paraíso watershed, São Manuel, SP were used. The combination of Remote Sensing and Geographic Information System technologies allowed representation of spatial distribution of the landscape and data integration in the diagnosis of geographic interest. The 2010 mapping showed 12 use categories, and the sugar cane crop had the largest land occupation, 48.25% of the area. The areas of permanent preservation amounted to 925.74 ha, which is an ideal value based on the Brazilian legislation. Mapping of land use conflicts showed intensive anthropic actions going 80.13% forward on PPAs, with only 19.87% remaining forests, which highlights their negative impact and illegal situations in these areas.

Caracterização do uso da terra em diferentes épocas na bacia hidrográfica do ribeirão paraíso- são manuel sp, por meio de sistemas de informações geográficas

This study aimed to evaluate a period of 38 years, the use and soil occupation of the Paradise River watershed, inserted in the citys of São Manuel and Areiópolis-SP using aerial photographs for the year 1972 and TM image (Thematic Mapper) obtained by the Landsat-5 satellite, in 2010, using geoprocessing techniques. The watershed in question is very important for the city of São Manuel-SP, because its urban area is inserted in its divisors which part of it belongs to the Environmental Protection Area (APA) Perimeter Botucatu-SP, considered a recharge area of the aquifer Guarani. Today, the development of agriculture faces challenges, which is to produce more food without impacting the environment. Allied to this concern, research institutions have sought new technologies that allow the detection and quantification of human actions, enabling interventions in order to minimize possible damage to the environment. Among these technologies can be cited Geographic Information Systems (GIS), which a large volume of data and information stored in a region at different times can be evaluated in the same time, suggesting different approaches to the planning of land use. The results of the mapping of areas of use and soil occupation result nine classes in 1972, and the coffee culture showed the biggest occupation (37.94%) of the total area. The 2010 mapping formulated twelve classes of use, which demonstrated the predominance of sugar cane (37.94%), on the areas occupied by coffee and pasture before. The land use maps of 1972 and 2010 showed results that show intense human activity in the modification of natural landscape.

Perfil da renda e do volume dos resíduos sólidos urbanos da associação de catadores de São Manuel - SP

The implementation of residue selective collection has brought to the city of Sao Manuel an incalculable benefit. It brought a better life for a group of adults and children that lives in a humanitarian condition of extreme poverty. These people live in an open-air dump, disputing the remains found in fifteen tons of garbage that are deposited at the site almost every day.The objective of this paper is to present thecollectors annual income profile and the volume of solid waste collected.To present these factors, the total and fractionated amount according to their material items, collected since the creation of the Association in February 2003 until December 2008, were considered., In addition,the social gains were enumerated. These factors were developed from a theoretical base for municipal solid waste involving environmental, social, and financial concepts. Based on these results it was found that the ACAPEL income value was above the average of other income indicators of the population analyzed, besides the social value enhance that the creation of the Association brought to the people who work there.
