Abstract
The situation of water management was investigated in eight wheat fields in agricultural lands of Marzabad, Mousian and Patak district, within irrigation networks of Dehloran Doyraj Reservoir dam. The downstream conditions in all borders were open ended and the volume of inflow water and outflow runoff hydrograph were measured. The application efficiency parameters in those fields compared with that in simulated values using WinSRFR software. The minimum and maximum runoff in the fields were 18.9% and 33.1%, respectively, compared with that in simulation mode that were 12% and 42%. In 75% of the fields, no deep percolation losses has been noticed. The average of minimum and maximum of application efficiency recorded as 60.3% and 80.5%, respectively, and in simulation mode 56% and 88%, respectively. The average of application efficiency measured in eight fields was 69.7%. Increase in efficiency of irrigation water can be attributed to mismanagement of unwanted low irrigation practices by farmers.
