Abstract

RYMBAI, P.N; DEY, S  and  JHA, L.K. The impact of topographical characteristics and land use change on the quality of Umbaniun micro-watershed water resources, Meghalaya. Ing. Investig. [online]. 2012, vol.32, n.2, pp.12-17. ISSN 0120-5609.

A watershed is a geohydrological unit draining at a common point. Such natural unit has evolved through rain water interaction with land mass, typically comprising arable land, non-arable land and natural drainage lines in rain-fed areas. Sustainable production depends on the health, vitality and purity of a particular environment in which land and water are important constituents. A pilot study was thus undertaken to study the geomorphology, land-use systems and their impact on water resource management on the Meghalaya Umbaniun micro-watershed. In this Micro-watershed (3951.18 ha), water body covers an area of 5.69ha (0.14%). The paper highlights the linkage between geomorphology, land use systems and its impact on quality of water resources on the Umbaniun Micro-Watershed, Meghalaya. Topographical and physical-chemical characteristics, such as pH, conductivity, dissolved oxygen, turbidity and water temperature, were used as environmental degradation indicators

Keywords : Geomorphology; land-use system; Umbaniun micro-watershed; water quality; water quantity.
