The Soil and Water Assessment Tool (SWAT) was calibrated for hydrology conditions in an agricultural watershed of Orestimba Creek, California, and applied to simulate fate and transport of two organophosphate pesticides chlorpyrifos and diazinon. The model showed capability in evaluating pesticide fate and transport processes in agricultural fields and instream network. Management-oriented sens...

economic valuation of water is useful in the administration and management of water. population growth and urbanization caused municipal water demand increase in iran. limited water resource supply and urban water network capacity raised complexity in water resources management. present condition suggests using economic value of water as a criterion for allocating policies and feasibility study...

According to experts, the inefficient agricultural sector has a dominant role in degrading water resources all over the world. Farmers’ conservational behavior is an important aspect of new integrated water management studies. Relevantly, various behavioral theories have been proposed in the field of environmental psychology. The main objective of the present comparative analysis and review stu...
