A Spatially Distributed Event-Based Model to Predict Sediment Yield
Runoff sediment yield Geographic Information System
2015/1/5
A study has been conducted in three sub-watersheds to model the spatial distribution of runoff and sediment yield. The basic structure of the model includes generation of runoff using SCS curve number...
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 ...
Use of rare earth oxides as tracers to identify sediment source areas for agricultural hillslopes
rare earth oxides sediment source areas agricultural hillslopes

Holocene Paleo-environmental Variability Reconstructed from a Lake Sediment Record from Southeast Greenland
Holocene Paleoenvironmental Variability Reconstructed a Lake Sediment Record Southeast Greenland
2014/10/21
Arctic climate variability over the Holocene has been both extensive and, at times, abrupt. Current understanding of these changes is still quite limited with few highresolution paleoclimate records a...
