Initial Dynamic System Design for Optimization of Gravity Irrigation Water Management (Open Gravitation Irrigation)

Abstract

The available water condition is smaller than the need of irrigation water of agricultural land that is needed is an expression of conflict in the field. To overcome this is by the regulation of several parameters, including the regulation of planting schedule and reduction of land area. The model of irrigation system used is based on the optimum area regulation of cultivable land. Parameters used to overcome this problem are planting schedule, land failure risk and k factor. The k factor is the ratio of water availability to the water requirement. The output of this system is optimal net benefit based on alternative land area of irrigation. The result of the formula will show the optimal amount of land that produces the optimal net benefit based on certain cropping schedule and certain effective rainfall. The system will also demonstrate that optimization will be achieved if there is a water balance between the availability and demand for irrigation water. The system referred to in this study is a dynamic system. The purpose of this research is to make early design of dynamic system to optimize agricultural irrigation system. The results obtained in this research form the formation of feedback loops and interaction between loops with each other on irrigation systems of agricultural land.
