Sub-watershed of Kanhar River basin a — g. ArcGIS software was utilized to calculate measures such as number of streams, length of streams, area and length of watersheds, and elevation ranges and were made use to estimate a number of parameters relating to linear bifurcation ratio, length ratioareal drainage density, stream frequency, shape, length of overland flow, etc. The mean bifurcation ratio Rbm characteristically ranges between 3.

Channel frequency density serves as a tool in establishing the erosional processes operating over an area; to be more specific, the same in relation to the stream orders and their characteristics provides data which can throw light even on the sequences of relief developments and the degree of ruggedness in the area Singh The symbol AW denotes Tropical Swanah region.
Bates R. It is also well observed that remote sensing satellite data is emerging as the most effective, time saving and accurate technique for morphometric analysis of a basin.
From the above inferences, it is evident that in watersheds with shorter length of overland flow values such as Shobanapuram, Sengattupatti, Talugai, Kallar, Periyakarruppu Odai and Kalungi, rain water will enter the stream relatively quickly, and lesser rainfall is sufficient to contribute a significant volume of surface run off to stream discharge, and the lag time will be shorter making them flash flood prone.

Various hydrological phenomena can be correlated with the physiographic characteristics of an drainage basin such as size, shape, slope of the drainage area, drainage density, size and length of the contributories, etc.

Chorley RJ a Climate and morphometry. Faniran A The index of drainage intensity—a provisional new drainage factor. In the Kanhar basin, the higher values of Rb indicate a strong structural control in the drainage pattern whereas the lower values indicate that the sub-basins are less affected by structural disturbances Strahler ; Vittala et al. Of these rocks, granites in the study area are seen with charnockites as enclaves, and are confined to the northern part especially to the Vedambiyam and Pulambadi Reserved Forests.

The count of stream channels in each order is termed as stream order. The analysis of stream frequency values of the watersheds of the study area shows that the stream frequency is low in Maruvattur, Pulambadi, Silaiyur and Valaiyur watersheds and is high in Kallar, Shobanapuram, Kalungi, Belur and Sengattuppatti watersheds.
Channel frequency density serves as a tool in establishing the erosional processes operating over an area; to be more specific, the same in relation to the stream orders and their characteristics provides data which can throw light even on the sequences of relief developments and the degree of ruggedness in the area Singh Slope analysis is an important parameter in geomorphological studies for watershed development and important for morphometric analysis.

The strike direction of the foliation of the major rock type of the study area, the charnockites, is predominantly NE—SW. Evaluation of morphometric parameters requires the analysis of various drainage parameters such as ordering of the various streams, measurement of basin area and perimeter, length of drainage channels, drainage density Ddbifurcation ratio Rbstream length ratio RLand relief ratio Rh.
Inc, New York Google Scholar. Among the watersheds of the study area, the maximum stream order ranges from third order to sixth order. In rest of the other watersheds these processes are likely to be moderate because of their moderate relief.
