Abstract
Geographical information system (GIS) & remote sensing has emerged as an efficient tool in delineation of morphometric analysis. GIS and image processing techniques can be employed for the identification of morphological features and analyzing properties of basin. The morphometric analysis of the drainage basin and channel network play an important role in understanding the geo-hydrological behavior of drainage basin and expresses the prevailing climate, geology, geomorphology, structural antecedents of the basin. Relief is typically defined as the difference in height between the high point and the low point on a landscape, in feet or in meters. It could also be defined more qualitatively: like "low relief plains" or "high relief rolling hills. The relationship among various drainage parameters and the aforesaid factors are well recognized by many workers. The drainage basin analysis is important in any hydrological investigation as assessment of groundwater potential, groundwater management, pedology and environmental assessment. Gadwal basin area is 83.75 sq km and four stream orders are there. Hydrologists and geomorphologists have recognized that certain relations are almost important between runoff characteristics, and geographic and geomorphic characteristics of drainage basin systems. Various important hydrologic phenomena can be correlated with the physiographic characteristics of drainage basins such as size, shape, slope of drainage area, drainage density, size and length of the contributories etc.
