Orientador: Fernando Braz Tangerino Hernandez / Resumo: O feijão comum (Phaseolus vulgaris L.) de grande importância sócio-econômica para o Brasil, sendo o segundo maior produtor e principal consumidor mundial. O objetivo neste trabalho foi compreender as metodologias disponíveis para manejo e avaliação do uso da água em culturas irrigadas e estimar a evapotranspiração atual (ETa) e ainda determinar coeficientes de cultura nas áreas cultivadas com feijão de inverno utilizando as técnicas baseadas em sensoriamento remoto (algoritmo SAFER - Simple Algorithm for Retrieving Evapotranspiration), confrontando-os com as estimativas da evapotranspiração da cultura (ETc) preconizados pelo Boletim FAO 56. O estudo foi realizado em condições irrigadas por pivô central com sete épocas de semeadura de feijão de inverno nos municípios de Rubinéia e Pereira Barreto. Cada época de semeadura recebeu um manejo de irrigação, realizado pelo próprio irrigante e uma simulação sugerida de irrigação mantendo os mesmos dados de ETo e chuva. As imagens do satélite LandSat 8 foram utilizas para execução do algoritmo SAFER para a obtenção da relação entre a evapotranspiração atual e a evapotranspiração de referência. Foram feitas a análise da produtividade de água em função da produção obtida para cada época de semeadura. Para as semeaduras de feijão de outono/inverno em Rubinéia, o irrigante possui a opção de utilizar dados das Estações Ilha Solteira e Marinópolis, fato que as ETo são semelhantes. Resultados obtidos das irrigações utilizadas pelo irrigante ...

The objective of this work was to understand the available methodologies for the management and evaluation of water use in irrigated crops and to estimate current evapotranspiration (ETa) and to determine crop coefficients in areas cultivated with winter bean using techniques based on remote sensing SAFER - Simple Algorithm for Retrieving Evapotranspiration), comparing them with estimates of crop evapotranspiration (ETc) recommended by FAO Bulletin 56. The study was conducted under central pivot irrigation conditions with seven winter bean sowing seasons in the municipalities of Rubinéia and Pereira Barreto. Each sowing season received an irrigation management, performed by the irrigator and a suggested irrigation simulation, maintaining the same ETo and rainfall data. The images of the LandSat 8 satellite were used to execute the SAFER algorithm to obtain the relation between the current evapotranspiration and the reference evapotranspiration. The water productivity was analyzed according to the production obtained for each sowing season. For the autumn / winter bean sowing in Rubinéia, the irrigant has the option to use data from the Ilha Solteira and Marinópolis Stations, a fact that ETo are similar. Results obtained from the irrigations used by the irrigator overestimated the water storage in the soil, so it was necessary to carr... (Complete abstract click electronic access below) / Mestre

A primary basis for settlement locations in the great basin by the Mormons was the availability of water. The settlement of Heber Valley was no exception. Water became quickly involved in two important and determining factors (cooperation and self-reliance) in the development of Mormon society in general and Wasatch County's society in particular. Likewise, these two factors influenced the direction in the development of water as it was utilized by the Mormons to establish the "Kingdom of God" on earth. Cooperation and self-reliance in Wasatch County were changed as modifications within the county were made as well as by other factors introduced in the county. Wasatch County farmers irrigation systems and institutions are today, a product of these two important factors and the modifications made on them. Co-operation and self reliance continue to be part of the agricultural way of life in Wasastch County.
