the present study aimed to monitor the land use change in the shazand watershed with different development policies using land use net changes and exchanges in land change modeller (lcm) forperiod of1973to2014and in sub-watersheds scale. in the study period, rangeland area reduced about 380 km2 and rainfed and irrigation farm lands increased successively 100 and 150 km2 in the first and the sec...

UNLABELLED BACKGROUND Mongolia's riverine landscape is divided into three watersheds, differing in extent of permafrost, amount of precipitation and in hydrological connectivity between sub-drainages. In order to assess the vulnerability of macroinvertebrate communities to ongoing climate change, we consider the taxonomic and functional structures of stream communities in two major watershed...

Background: Mongolia’s riverine landscape is divided into three watersheds, differing in extent of permafrost, amount of precipitation and in hydrological connectivity between sub-drainages. In order to assess the vulnerability of macroinvertebrate communities to ongoing climate change, we consider the taxonomic and functional structures of stream communities in two major watersheds: The Centra...

Marijuana (Cannabis sativa L.) cultivation has proliferated in northwestern California since at least the mid-1990s. The environmental impacts associated with marijuana cultivation appear substantial, yet have been difficult to quantify, in part because cultivation is clandestine and often occurs on private property. To evaluate the impacts of water diversions at a watershed scale, we interpret...

Knowledge of design peak flow is crucial in various applications related to hydrology, hydraulics and water resources management. However, obtaining challenging especially ungauged basins lacking discharge observations, a circumstance that does not allow the calibration advanced hydrological models. Recently, new method called EBA4SUB (Event-Based Approach for Small Ungauged Basins) was introdu...

Excessive loads of nutrients transported by tributary rivers have been linked to hypoxia in the Gulf of Mexico. Management efforts to reduce the hypoxic zone in the Gulf of Mexico and improve the water quality of rivers and streams could benefit from targeting nutrient reductions toward watersheds with the highest nutrient yields delivered to sensitive downstream waters. One challenge is that m...

nowadays multicriteria decision making (mcdm) methods are a useful tool for investigating natural resources and toaddress problems related to hydro systems. the goal of this research was to assess the daliri standardization method(dsm) to prioritize and make selections for application to mcdm. and to compare the dsm method with the utilityadditive (uta) method. the (dsm) method, unlike the (uta...

In a split sample design, we examine the impact of federal funding availability on Willingness to Pay (WTP) for watershed management program attributes and tradeoffs in a choice experiment. We also evaluate how presenting respondents with different sets of choice attributes, in alternative survey designs, affects the estimation of preference functions. We also compared preferences for watershed...
