The task of the master's thesis on the topic of "The determination of the loss of the soil erosion and the draft erosion control measures" is the first to describe in general what is soil erosion and erosion control measures, what they may be. Then the work focuses on the calculation of the average long-term loss of soil erosion and loss of soil from torrential rain on the selected watersheds. These steps follows its own draft anti-erosion measures. The measures are designed to reduce the loss of soil found in the basin. The water catchment area, which is the erosion of the watershed is determined, the stream Pradlenka.

Estes problemas não se restringem a produtividade agrícola, como também favorecem o empobrecimento do meio rural, a poluição e assoreamento dos cursos d’água, a dependência financeira e tecnológica dos sujeitos sociais etc. Para compreender as dinâmicas e os fatores relevantes na perda de solo foi aplicado distintos métodos de determinação, um de estimação direta, por meio das parcelas de monitoramento com pinos de erosão e um indireto, por meio da Equação Universal de Perda de Solos (EUPS), que permitissem a comparação dos resultados obtidos em campo com os da aplicação do modelo. O estudo foi realizado em duas propriedades agrícolas que possuem características naturais e de uso e ocupação distintas, atribuindo-lhes complexidades espaciais particulares. Uma localiza-se em Getulina e é destinada a pecuária e a outra localiza-se em Vera Cruz com a produção de café. Foi possível identificar nas propriedades agrícolas características naturais que tornam seus solos suscetíveis a perda por processos erosivos, porém, que as formas de uso e ocupação destes espaços foram fundamentais para o entendimento dos totais de perda registrados pelos métodos de determinação. Esta complexidade fundamenta a necessidade de abordar a perda de solo como fenômeno geográfico, decorrente de aspectos naturais e sociais que expressam demandas, interesses e funcionalidades socialmente construídas que fundamentam sua apropriação. / Looking to understanding the dynamics involving the soil loss, aiming at both its measurement as well as the actions aimed use at their conservation and recovery, is gaining space in the scientific world due to environmental and economic problems resulting from this degradation. These problems are not restricted to agricultural productivity, but also promote rural impoverishment, pollution and siltation water courses, social subjects financial and technological dependence, etc. The different methods of determination, a direct estimation, through the monitoring plots with erosion pins and an indirect, through the Universal Soil Loss Equation (USLE) was applied to understand the dynamics and relevant factors on soil loss and also to allow the results comparison obtained in the field where was applied the models. The study was conducted in two farms where we could find different use and occupation natural characteristics assigning them particular spatial complexities. One farm is located in Getulina and is intended for livestock (animals) and the other is located in Vera Cruz where they grow coffee, both in southeastern Brazil, São Paulo State. It was possible to identify the properties that make their natural features agricultural soils susceptible to loss through erosion, however, that the use and occupation forms of these spaces were fundamental for the understanding the loss totals recorded by determination methods. This complexity is motivated by the need to address the soil loss as geographical phenomenon, resulting from natural and social aspects that express demands, interests and socially constructed features that underlie your ownership. / 2014/02230-6

Resumo: O trabalho apresenta uma aplicação das geotecnologias (Sensoriamento Remoto e SIG) na seção do alto curso da bacia hidrográfica do Ribeirão Cachoeirinha, à montante da cidade de Iracemápolis, S.P.. O objetivo foi indicar a importância da aplicação daquelas técnicas, com o suporte do modelo EUPS, como subsídio ao planejamento sustentável do uso das terras, com ênfase na ocupação agrícola. Apresenta-se, também, neste estudo, uma discussão referente à inserção destas técnicas no âmbito dos estudos geográficos, bem como suas limitações. A partir da análise dos dados, foram geradas cartas de síntese referentes aos indicadores da erosão hídrica do solo: potencial natural de erosão (PNE), riscos e expectativa de erosão em relação à ocupação agrícola das terras. Além disso, a série de fotos, obtidas através do trabalho de campo, possibilitaram avaliar as limitações do modelo EUPS em determinadas situações e tecer algumas considerações reflexivas a partir dos resultados obtidos. / Abstract: This paper shows na application of the geotecnologies (Remote Sensing and GIS) in the section, of the high course of the basin of the River Cachoeirinha, above the town of Iracemápolis, S.P. The objective was to indicate the importance of the application of those techniques, with the support the USLE (Universal Soil Loss Equation) model, as a subside to the sustainable planning of the land use emphasizing the agricultural occupation. It is also shown, in this study, a discussion referring to the insertion of the techniques in the scope of geographic studies, as well as their limitations. From the analysis of the data syntheses maps were produced refering to the indicators of hidric erosion of the soil: natural potential of erosion (NPE), risksand expectancy of erosion in relation to the agricultural occupation of the lands. More over, the series of photos, obtained though the field work, made it possible to evaluate the limitations of the USLE model in some situations and made some reflexive considerations from the results. / Orientador: Sérgio dos Anjos Ferreira Pinto / Coorientador: Francisco Lombardi Neto / Banca: Magda Adelaide Lombardo Fruehauf / Banca: Maria Isabel Castreghini de Freitas / Banca: Teresa Gallotti Florenzano / Banca: Manuel Enrique Gamero Guandique / Doutor

A Área de Proteção Ambiental do rio Uberaba (APA) é uma Unidade de Conservação criada com o objetivo de garantir a qualidade das águas do rio Uberaba, sendo este, o manancial de abastecimento público da cidade de Uberaba - MG. É caracterizada como uma unidade de conservação de uso sustentável, e algumas atividades altamente impactantes vêm sendo realizadas na sua área, com isso, causando diversas alterações no meio, tais como erosão, eutrofização de cursos d’água e alterações na qualidade e quantidade de água. Objetivou-se nesta proposta identificar as áreas prioritárias para conservação do solo e da água na Área de Proteção Ambiental do rio Uberaba utilizando técnicas de geoprocessamento. As áreas foram definidas a partir da estimativa de perdas de solos pela Equação Universal de Perda de Solo e dos usos e ocupação dos solos nas Áreas de Preservação Permanente. O modelado do relevo fora mapeado em 5 unidades: Dissecado Homogêneo de Topo Tabular – Dt (42,39%); Dissecado Homogêneo de Topo Convexo – Dtc (24,78%); Rampa de Colúvio– Arc (17,21%); Pediplano Degradado Inumado ‒ Pgi (11,45%); e o Dissecado Estrutural de Topo Convexo – DE (4,17%) da APA.

The Uberaba River Environmental Protection Area (EPA) is a Conservation Unit created with the objective of guaranteeing the quality of the waters of the Uberaba River, which is the source of public supply of the city of Uberaba - MG. It is characterized as a sustainable use conservation unit, and some highly impacting activities have been carried out in its area, causing several changes in the environment, such as erosion, eutrophication of watercourses and changes in water quality and quantity. The objective of this proposal was to identify priority areas for soil and water conservation in the Uberaba River Environmental Protection Area using geoprocessing techniques. Areas were defined by estimating soil losses by the Universal Equation of Soil Loss and land use and occupation in Permanent Preservation Areas. The relief models were mapped in 5 units: Homogeneous Dissected Tabular Top - Dt (42.39%); Top Convex Homogeneous Dissected - Dtc (24.78%); Coluvium Ramp - Arc (17.21%); Degraded Pediplane - Pgi (11.45%); and the EPA Convex Top - Structural Dissection (4.17%). The Natural Erosion Potential presented low values (<100 t ha-1 year-1 ) in 41.99% of the APA, average values (100-200 t ha-1 year-1 ) in 25.64% and the high values (200-600 t ha-1 year-1 ), very high (600 -1...

Diploma thesis deals with the evaluation of threats on agriculture land by water erosion in the cadastral area of village Čikov before and after proposing of counter – erosion measures. For the calculation of erosion was used Universal equation (USLE) according to Wischmeier and Smith. The analytical operations leading to the calculation individual factors Universal equation and average long-term loss of soil by water erosion were made using the software ArcGIS, USLE2D and LS – Converter. Partial analysis are presented in the form of map outputs. In the interest area, after the calculating of the USLE, it was found that on 30,39 ha occurs very strong erosion which represents 4,73 % of the solved area. Strong erosion occurs on 36,56 ha (5,68 %), medium erosion on 229,94 ha (35,75 %) and slight erosion on 346,33 ha (53,84 %). Thanks to the proposed counter – erosion measures, very strong erosion in the interest area was completely eliminated. Strong erosion was reduced to only 2,52 ha (0,39 %) and medium erosion to 74,79 ha (11,58 %). Slight erosion increased to 566,21 ha (88,03 %).

Diploma thesis is focused on creating anlysis of erosin risks on agriculture soils in cadastral areas Bor u Nedvědice and Sejřek. Thesis deals with calculation of erosion risks on ArcGIS program platform using the map baisics of State land office and Czech Geodetic and Cadastral Office. The fundamental goal of thesis is find out a present of erosion risks in interests area. For calculation of erosion will be used universal equation of USLE (Universal soil loss equation). The result of thesis is proposal of measures which will lead to reduce the influence of water erosion on agriculture soils. Protection of agriculture soils should be integral part of rural development and maintaining natural functions of rural, agriculture landscape.

This Diploma Thesis is focused on the analysis of the Ketkovice cadastral area in terms of runoff and erosion conditions. The QGIS software was chosen for the analysis. For this reason, instructions for this software are prepared, focusing on runoff and erosion conditions, as an appendix to the Diploma Thesis. Other software programs used are USLE2D and DesQ-MaxQ. The first part deals with the analysis of the area of interest. The second part deals with the problem itself, at first the methods used to determine runoff and erosion conditions are introduced, then anti-erosion measures, at the end of this part the software programs used are briefly described. The last third part is devoted at first to the evaluation of runoff and erosion conditions before the design of the measure, then to the design of the measure itself, finally to the evaluation after the design of the measure. In case of erosion conditions, two variants of calculating long-term soil loss are considered before and after the proposed measures. In the first variant, a constant value of the factor R=40 MJ.ha.cm.h is considered in the Universal Soil Loss Equation and in the second variant this value is increased with respect to the climate change.
