tidal condition Hooghly estuary
2015/8/14
The lower stretch of Gangetic delta in the Indian sub-continent is noted for its rich mangrove biodiversity, natural calamities, and livelihood-supporting matrix of millions of people and is the only ...
SWAMP GIS: A spatial decision support system for predicting and treating stormwater runoff
Stormwater runoff decision support
2015/8/14
SWAMP GIS is a spatially-based decision support system that empowers users in rural areas within Oregon (USA) with tools for predicting and mitigating stormwater runoff. SWAMP GIS is made freely avail...
Assessment of Spatial Patterns of Sediment Transport and Delivery for Soil and Water Conservation Programs
off-site soil erosion soil erosion deposition model
2015/8/14
Soil erosion has tremendous impacts on most river systems throughout the United States. Such non-point pollution results from land-use and agricultural practices and leads to sedimentation downstream,...
Spatial Variability and Prediction Modeling of Groundwater Arsenic Distributions in the Shallowest Alluvial Aquifers in Bangladesh
Arsenic Bangladesh distribution spatial variability semivariogram prediction models
2015/8/13
Elevated arsenic in groundwater is the greatest environmental problem in Bangladesh. Spatial variability of arsenic in groundwater has been examined by semivariogram analysis that revealed high degree...
Estimating Spatial Sediment Delivery Ratio on a Large Rural Catchment
soil erosion sediment yield sediment delivery ratio modelling
