Estimating Spatial Sediment Delivery Ratio on a Large Rural Catchment
soil erosion sediment yield sediment delivery ratio modelling
2015/8/11
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...
Spatial Variability of Groundwater Recharge - II. Factors Affecting Variability and Taking Account of it in Estimating Recharge
Spatial variability Groundwater recharge Sri Lanka
2015/8/6
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 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
2015/8/6
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 ...
A Spatial Technique for Estimating Streambank Erosion Based On Watershed Characteristics
watershed modeling streambank erosion sediment transport
2015/1/4
A GIS-based technique was developed for estimating streambank erosion rates for more accurately predicting total sediment loads at the watershed scale without the use of detailed field data. This tech...
An inversion method based on multi-angular approaches for estimating bare soil surface parameters from RADARSAT-1
multi-angular approaches estimating bare soil surface parameters
2010/12/22
This paper focuses on inversion of these parameters using a multi-angular approach based on RADARSAT-1 data with incidence angles of 35° and 47° (in mode S3 and S7). This inversion was performed with ...

ESTIMATING GROUNDWATER RECHARGE IN THE DRY ZONE OF SRI LANKA USING WEEKLY, 10-DAILY OR MONTHLY EVAPOTRANSPIRATION DATA
GROUNDWATER MONTHLY EVAPOTRANSPIRATION DATA DRY ZONE
2009/10/19
Howard and Lloyd (1979) have shown that daily values for rainfall and potential evapotranspiration are required in estimating recharge with a soil water balance model. However, available data may not ...
COMPARISON OF METHODS FOR ESTIMATING REFERENCE EVAPOTRANSPIRATION IN SOUTHERN CALIFORNIA
California Irrigation Management Information System evapotranspiration
2009/10/12
A significant part of precipitation returns back to the atmosphere by evapotranspiration. Developing formulations aimed at accurately quantifying evapotranspiration over a given region can aid a wide ...
Estimating spatially distributed monthly evapotranspiration rates by linear transformations of MODIS daytime land surface temperature data
evapotranspiration rates land surface temperature
2009/7/22
Under simplifying conditions catchment-scale vapor pressure at the drying land surface can be calculated as a function of its watershed-representative temperature () by the wet-surface equation (W...
A comparison of methods for estimating soil characteristics in regional acidification models; an application of the MAGIC model to Scotland
Acid Neutralising Capacity soil depth soil physico-chemical
2009/6/5
The results from an application of MAGIC (Model of Acidification of Groundwater In Catchments) to 733 Scottish catchments are presented. The availability of representative, good quality soil data is f...
