Determination of Optimal Environmental Flow Acquisition in Kor Basin, Doroudzan Dam AgEcon
Asad Falsafi Zadeh, Neda; Sabouhi Sabouni, Mahmood.
In current study, an irrigation examination and acquisition of environmental water in Kor River fields, that is dominated from Doroudzan dam to Bakhtegan Lake, was done by an integrated economy-environmental model. The model was considered by economic, hydrologic and agronomic components. In the economic component, an optimal harvesting of water was done using non-linear programming in two scenarios; with and without environmental water constraint. Solutions from simulation of environmental data in the hydrologic component, was used as initial data in the economic component. In the agronomic component, actual crop yield in wet, normal and dry years was determined using the relationship between crop yield and irrigation water amount. Results showed that,...

Economic and Groundwater Use Implications of Climate Change and Bioenergy Feedstock Production in the Ogallala Aquifer Region AgEcon
Wang, Weiwei; Park, Seong Cheol; McCarl, Bruce A.; Amosson, Stephen H..
The sustainable water use especially for irrigated agriculture in the Texas Panhandle Region is a major concern. A semi-arid climate and average low rainfalls results in little surface water being available year-round. The Ogallala Aquifer is the primary source of irrigation water in this region. The intensive irrigated agricultural production and growing livestock industry have led to substantial decline of water tables. Furthermore, climate change and growing bioenergy feedstock productions exacerbates the water shortage and quality problems. Given the critical dependence of the regional economy on Ogallala Aquifer, underground water use is an intergenerational issue that must be evaluated in terms of the sustainability of agricultural activities in the...
