This work presents a software named DimSulco, developed in the Visual Basic language, version 5 for Windows 95, with the objective of helping the user to design and to evaluate furrow irrigation systems from previous knowledge of fundamental project parameters. It was structured in five modules: I - Without deficit irrigation and defined furrow length; II - Without deficit irrigation and undefined furrow length; III - Deficit irrigation and defined furrow length; IV - Deficit irrigation and undefined furrow length and V - Reuse of irrigation runoff system. The modules I and III are divided in two sub-modules, which allow the design and performance of the system with and without cutback inflow. The modules II and IV are divided in four sub-modules including the options: a) Without cutback inflow and advance time (Ta) equal to ¼ opportunity time for infiltration of the depth of water at the final end (To); b) With cutback inflow and Ta equal to ¼ To; c) Without cutback inflow and Ta equal to To and d) With cutback inflow and Ta equal to To. The module V allows the design of irrigation runoff reuse systems using any of the previously designed modules, calculating the basic elements of the each set and performance of irrigation variables. To illustrate an application of this software one example of a furrow irrigation system was used.
