Interactive Computer Program for Design of Subsurface Drip Irrigation System

A computer program has been developed for the design of subsurface drip irrigation system.It could be applied for calculation of small scale fields with an area up to 50 ha.The program includes two main parts: crop water requirements and hydraulic calculations of the system.It has been developed in Graphical User Interface (GUI) in MATLAB and gives opportunity for selecting some parameters from interactive tables such as: agro-physical soil properties, characteristics of the corresponding crop, climatic data.It allows the user of the program to assume and set up a definite value, for example the emitter discharge, plot parameters and etc.Eight cases of system layout according to the water source layout and the number of plots of the system operation are laid into hydraulic section of the program.It includes the design of lateral, manifold, main line and pump calculations.
