Water Requirements of Wheat Crops in a Small Watershed by Using CROPWAT

Water requirement of crops in Khuzestan province

One of the effective steps in use of water resources is accurate estimation of plants water requirement. Lack of accurate estimation of this amount leads to water loss and failure to achieve optimum yield, reduced potential of production, soil resources degradation by too much irrigation or lack of enough leaching and salinization of soils by irrigation less than necessary level, which would ul...

Estimation of Evaporation and Transpiration of Wheat Plant in Zaraghan Station Using CROPWAT Model

In this research, amount of evaporation and transpiration and water requirement of wheat plant for Marvdasht town (representation station: Zaraghan) during 17-years statistical duration from 1989-2005 and properties of plant and soil are calculated using CROPWAT software. At the first, trends of dry and wet periods for mentioned station were determined using long-term average of climatic data (...

Optimal allocation of water resources in Khanmirza watershed using WEAP

Abstract Constraints on water resources and increasing the number and variety of water users has led to appeal of the importance of optimal water allocation. The Khanmirza watershed in Chaharmahal Va Bakhtiari Province, has experienced unsustainable development by relying on groundwater resources.  As a result of this imbalance, a dramatic drop occurred in the aquifer of the Khanmiza plain. Th...
