Easyspray: software para dimensionamento de sistemas de irrigação por aspersão convencional em regiões moçambicanas

Abstract

Correct hydraulic design is necessary to guarantee technical and economical viability of an irrigation system. Due o several variables to be considered, it becomes increasingly difficult to be carried out manually. Furthermore, due to the fact that solid set sprinkler irrigation requires, in some cases, a change in pipe positions, the correct design is very important to obtain water and energy efficiency; in addition it enables analysis of different scenarios, for better selecting an adequate layout. Therefore, the main objective of this work was to develop a software to design solid set sprinkler irrigation systems for small properties and family farmers in Mozambique. For this, Visual Studio was used, in which a database was prepared with climatic information, soil characteristics and data of the main crops produced in Mozambique. Coded equations were inserted into the Visual Basic programming language and through these, computational routines were generated to obtain a graphical interface that allows the user to perform data entry and observe the results obtained. The software presented a graphic and intuitive interface, besides being able to be installed and to work efficiently, in computers that use Windows, without depending on other auxiliary programs.
