The influence of woven geotextiles on ponding time and overland flow
hillslope jute and coir materials KINFIL hydrological model Norton Ladder Rainfall Simulator
2016/8/2
Nowadays, both synthetic and natural geotextiles are used to mitigate water erosion processes on hillslopes. Jute and coir are most suitable materials for the production of woven geotextiles. They are...
Improving overland flow routing by incorporating ancillary road data into Digital Elevation Models
