Estimating Spatial Curve Number for Hydrologic Response analysis of a small Watershed
Watershed modeling Geographic Information System GIS
2015/1/6
An approach to estimate the curve number (CN) at each pixel unit of a satellite imagery, which is a key parameter in the widely used Soil Conservation Service Curve Number (SCSCN) hydrologic model, is...
Estimating Limiting Nutrient Loadings in an Interacting Surface and Ground Water Basin
sediment Snake River Basin Idaho
2015/1/6
Watershed management requires the determination of both point and non-point sources of pollution within a watershed. The primary non-point source pollutants in a typical watershed are nutrients (mainl...
Estimating Spatial Sediment Delivery Ratio on a Large Rural Catchment
soil erosion sediment yield sediment delivery ratio
2015/1/6
Soil erosion and sediment yield from catchments are key limitations to achieving sustainable land use and maintaining water quality in streams, lakes and other water bodies. Controlling sediment loadi...
Estimating sediment yield using Agricultural Non-Point Sources (AGNPS) model: The effects of slope information from different GIS softwares
Geographical Information System GIS slope information Sediment yield AGNPS model tropical catchment
2015/1/4
This study compares the effects of slope information derived from three GIS software on sediment yield as estimated using AGNPS model. The three GIS software are IDRISI for Windows, ERDAS Imagine and ...
Spatial Variability of Groundwater Recharge - II. Factors Affecting Variability and Taking Account of it in Estimating Recharge
Spatial variability Groundwater recharge Sri Lanka
2015/1/4
The accompanying paper provided evidence to suggest that spatial variability of groundwater recharge is ‘true’ variability. This paper attempts to determine the major causes of such variability even a...
ESTIMATING SEDIMENT YIELD OF A SMALL CATCHMENT IN A TROPICAL REGION USING THE AGNPS MODEL：THE WATERFALL RIVER CATCHMENT, PENANG, MALAYSIA
SEDIMENT YIELD Agricultural Non-Point Source SMALL CATCHMENT TROPICAL REGION
2009/10/13
This paper presents the result of our research in testing the applicability and performance of the AGNPS (Agricultural Non-Point Source) model to estimate sediment yield of a small tropical catchment....
An empirical method for estimating future flood risks for flood warnings
flood risks flood warnings
2009/5/18
Since medium and long-term precipitation forecasts are still not reliable enough, rough estimates of the degree of the extremity of forthcoming flood events that might occur in the course of dangerou...
Estimating spatial mean root-zone soil moisture from point-scale observations
soil moisture point-scale spatial mean
2009/5/15
Root zone soil moisture is a key variable in many land surface hydrology models. Often, however, there is a mismatch in the spatial scales at which models simulate soil moisture and at which soil moi...
Estimating surface fluxes over the north Tibetan Plateau area with ASTER imagery
surface fluxes north Tibetan Plateau area
2009/4/27
Surface fluxes are important boundary conditions for climatological modeling and Asian monsoon system. The recent availability of high-resolution, multi-band imagery from the ASTER (Advanced Space-bor...
