Diseño de redes colectivas de riego cuando se realiza variación de cultivos

Abstract

Irrigation networks in the country today are designed to satisfy the water requirements of the most demanding crop, without considering supposed cases in which crop pattern could present variations, which result an oversized network or unable to function correctly to certain scenarios. This research raises a process for designing a collective irrigation network in which are supposed eight possible variations in the original crop pattern. For this, it has developed demand curves weighted irrigation which form an envelope of hydric requirements of which the peak value was taken for design. The first model Clément was used to calculate the circulating flows per line and the network was designed to demand for different hydric requirements weighted each alternative crop raised, achieving decrease by 17.7% the total cost of piping between the design made for the needs of more demanding crop and design made to satisfy an average alternative crops.
