JHA, V. C.  e  KAPAT, S.. Rill and gully erosion risk of lateritic terrain in South-Western Birbhum District, West Bengal, IndiaRisco a erosão em ravinas e voçorocas nos terrenos lateríticos de South-Western Birbhum District, West Bengal, India. Soc. nat. (Online) [online]. 2009, vol.21, n.2, pp.141-158. ISSN 1982-4513.  http://dx.doi.org/10.1590/S1982-45132009000200010.

It is a known fact that no part of the earth surface is free from threat.It applies to Birbhum District, West Bengal, Indian Lateritic Terrain also. The existing terrain is characterized by mainly climatogenetic processes. Though the impact of climate change is vital in the shaping of the lesser topographies in the study-area. The study-area is characterized by micro landforms e. g. rills, gullies, water falls, terraces, gorges type features and limestone topographic type features. The denudational processes are very significant in the area in general but the differential erosion is evident in particular. It resembles the topographies with the African and the Brazillian Highlands. This paper interprets the rill and gully erosion risk in the lateritic terrain and their consequences in regional sustainable development and environmental management
