In a complex watershed, isolated wetlands, riparian wetlands and riparian buffers provide important functions such as flood attenuation and water quality improvement. For conservation purposes, it is ...
Agricultural lands are considered to be a major source of nonpoint source pollutants such as sediment, pesticides and nutrients in the United States. Conservation practices have been tested for their ...
The primary objective of this research involves mapping out and validating the existence of sub surface drainage tiles in a given cropland using Remote Sensing and GIS methodologies. The process is de...
In a complex watershed, isolated wetlands, riparian wetlands and riparian buffers provide important functions such as flood attenuation and water quality improvement. For conservation purposes, it is ...
A comprehensive, GIS-based modeling approach was developed to enable accurate prediction of nutrient loads in watersheds throughout the state of Pennsylvania; particularly those watersheds for which...
Thirty-two watersheds (31–4350 km2), in the Blue Nile Basin, Ethiopia, were hydrologically characterized with data from a study of water and land resources by the US Department of Interior, Bureau of ...
Distributed energy and water balance models require time-series surfaces of the climatological variables involved in hydrological processes. Among them, solar radiation constitutes a key variable to ...
The accuracy of photogrammetry in determining snow depth in mountainous rangeland watersheds was evaluated on a 0.41-km2 subbasin of the Reynolds Creek Experimental Watershed, located in the Owyhee ...
The diverging overland flow model is utilized to predict surface runoff from several natural watersheds. The Lax - Wendroff scheme is used to obtain numerical solutions. This scheme is explicit, sin...
Storm runoff production by saturation overland flow has been studied in two small watersheds in south-central Ontario. One is in rural land use and contains a wetland. The total saturated zone is at...
Nutrient concentrations and exports were monitored for eight years in two agriculture- dominated watersheds in the central part of the Vastgota Plain in Sweden. The hydrology and the nutrient concen...
This study proposes an analytical method for the estimation of time lag for forested mountainous watersheds. The water flow in a watershed is separated and analyzed in two phases, the land or hillslop...
Soil moisture content was estimated daily by a energy balance and water budget (EBWB) analysis of two small subwatersheds in the Walnut Gulch Experimental Watershed near Tombstone, Arizona. One wate...
The paper deals with nutrient runoff monitoring results and calculated nutrient budgets on catchment level in small agricultural watersheds in Estonia. A special programme for monitoring of nutrient...
The objective of this study was to apply a continuous hydrologic model that uses the Curve Number method to a large undeveloped watershed, calibrate the model and obtain parameter values; and, from th...
