Design of Optimal Length of Furrows though Infiltration Studies

Abstract

Design of Optimal Length of Furrows Though Infiltration Studies In order to optimize the usage of water in agriculture, it is necessary to increase the efficiency of irrigation systems, especially those of surface irrigation. One of the steps to be made to achieve this goal is the optimal design of surface irrigation.

It this article the design variables of furrow irrigation, that includes length of furrow, inflow rate and irrigation time (time of cutoff), were calculated to minimize the irrigation costs, the objective function, and to obtain a maximum application efficiency. The objective function encompasses water, labor, head ditch and furrow digging (ditch constructions) costs. Labor cost is irrigation time’s function and the latter is dependent on water advance period in the furrows.
