Rainsplash erosion: a case study in Tekala River catchment, east Selangor Malaysia

This paper discusses rainsplash erosion in forest reserves. The study was carried out at a dipterocarp forest reserve area in the Tekala river catchment, Hulu Langat Selangor. It shows that even under forest cover, soil erosion still occurs. Most of the eroded material from the study sites enters t...
