Análise de eficiência hidráulica e modelagem de sistema de irrigação por gotejamento

Abstract

Over time, water scarcity was exacerbated by irregular distribution, population growth, expansion of industry and agriculture, the latter being the main user of water resources, representing about 70% of world consumption. To reduce the waste of resources in the agricultural sector, it is necessary to look for ways to increase the efficiency of irrigation. Thus, the present work aims to analyze the hydraulic efficiency of a small drip irrigation network existing in the municipality of Pedro II - PI and its computational modeling through a hydraulic simulator. Consisting of a survey of data in the field and use of input data, such as topography, length and constitution of pipes and drippers, in the EPANET software. From the results, the network was considered excellent in the emission efficiency criterion and the flow collection method of Keller and Karmelli (1975) suggested for small networks. Furthermore, it was concluded that the effects caused by the drippers can be represented by the roughness in the hydraulic simulation in EPANET. Furthermore, it was concluded that the effects caused by the drippers can be represented by the roughness in the hydraulic simulation in EPANET.
