reliable estimates of runoff are required as a part of the information sets that help watershed managers make informed decisions on water resources planning and management. this study was carried out in shafaroud watershed located in the north of iran. in order to achieve the best runoff simulation in the study area, first rainfall data of four stations during 1998 to 2011 were collected and co...

Multimedia services for mobile phones are becoming increasingly popular thanks to capabilities brought about by location awareness, customized programming, interactivity, and portability. With mounting attraction to these services there is desire to seamlessly expand the mobile multimedia experience to stationary environments where high-resolution displays can offer significantly better viewing...

We consider a lowerand upper-bounded generalization of the classical facility location problem, where each facility has a capacity (upper bound) that limits the number of clients it can serve and a lower bound on the number of clients it must serve if it is opened. We develop an LP rounding framework that exploits a Voronoi diagram-based clustering approach to derive the first bicriteria consta...

This paper presents results of spatial and temporal analyses of hydro-climatic regimes and simulation of climate-induced hydrologic changes in the Lake Winnipeg watershed. The hydrologic and agricultural chemical yield model, Soil & Water Assessment Tool (SWAT), was employed for the simulation of hydrologic scenarios in the Upper Assiniboine catchment of the Lake Winnipeg watershed, Canada. Ana...

This study evaluated the reduction effect of non-point source pollution by applying best management practices (BMPs) to a 1.21 km2 small agricultural watershed using a SWAT (Soil and Water Assessment Tool) model. Two meter QuickBird land use data were prepared for the watershed. The SWAT was calibrated and validated using daily streamflow and monthly water quality (total phosphorus (TP), total ...

Renewed harmful algal blooms and hypoxia in Lake Erie have drawn significant attention to phosphorus loads, particularly increased dissolved reactive phosphorus (DRP) from highly agricultural watersheds. We use the Soil and Water Assessment Tool (SWAT) to model DRP in the agriculture-dominated Sandusky watershed for 1970-2010 to explore potential reasons for the recent increased DRP load from L...

Topics such as the sustainability and vulnerability of land management practices on water quality and quantity are very important in these days both for decision makers and for citizens. The enviroGRIDS FP7 project addresses some of these topics in the Black Sea Catchment area. One of the software tools developed in this project is gSWAT. It allows the calibration of SWAT hydrological models in...

The paradigm of integrated water resources management requires coupled analysis of hydrology and water resources in a river basin. Population growth and uncertainties due to climate change make historic data not a reliable source of information for future planning of water resources, hence necessitating climate and landuse change impact studies. This work presents an integrated modeling approac...

For two watersheds in the northern Midwest United States, we show that landscape depressions have a significant impact on watershed hydrology and sediment yields and that the Soil and Water Assessment Tool (SWAT) has appropriate features to simulate these depressions. In our SWAT models of the Willow River in Wisconsin and the Sunrise River in Minnesota, we used Pond and Wetland features to cap...

OBJECTIVE To determine the frequency of various genotypes of Hepatitis C virus in District Buner, Swat. METHODS This Descriptive case series study was conducted at District Headquarter Hospital Daggar, and Bilal Medical Trust, Pir Baba, Swat, Pakistan from January 2007 to June 2008. A total of 400 patients, 154 Male and 246 Female aged 16-65 years (Mean age 31 +/- 13 years) without clinical a...
