ABSTRACT

 

Morphometric analysis becomes important when watershed development and management plans are taken into consideration. Morphometric analysis was carried out on Laskmantirtha basin using satellite imageries and topographic maps on a scale map of 1:50,000 to determine its drainage characteristics. Remote sensing and GIS tools have proved to be an efficient tool in this study in drainage delineation and calculation of some of the aerial and linear parameters. The drainage pattern of the basin is dendritic and includes a sixth order stream. The development of stream segments in the area is more or less effected by rainfall. The erosional process of the basin is the result of the sub surface lithology. The shape parameters also reveal the elongated shape of the basin.
