Evaluation of AnnAGNPS and its applications in a semi–arid and semi–humid watershed in Northwest China
The main goal of this study was to evaluate the performance of AnnAGNPS (Annualised Agricultural Non–Point Source Pollution Model) in simulating runoff, sediment loading and nutrient loading in a semi–arid and semi–humid watershed of an area of 1481sq km, located in Northwest China. This model was first calibrated and tested by historic monitoring data and then the validated model was used to ...

Comparison of different targeting methods for watershed management practices implementation in Taleghan dam watershed, Iran
Soil erosion and sediment control is important in watersheds with planned dam construction. For an efficient implementation of watershed management practices, identification of critical areas is vital. Many studies have made an effort to identify and prioritize critical sub-watersheds. But very limited studies have been conducted to rank sub-watersheds in terms of their sediment yield ...

Cost-effectiveness analysis of different watershed management scenarios developed by simulation–optimization model
The effort to control sediment yield at watershed scale is an ongoing challenge that needs to take into account trade-offs between two conflicting objective functions, i.e. economic and hydrologic criteria. Therefore, researchers have coupled hydrologic and multi-objective optimization models to find Pareto-optimal solutions. However, very limited studies have been conducted to analyse the ...

Effect of non-point source runoff and urban sewage on Yaque del Norte River in Dominican Republic
A Yaque del Norte, Dominican Republic watershed survey monitored dissolved oxygen, eutrophication from point and non-point sources, and high conductivity resulting from agricultural runoff. The upper mainly forested watershed had good water quality except for untreated sewage from the city of Jarabacoa. The mid-watershed had a deforested landscape, mixed agriculture and the city of Santiago ...
