Its just 15 km far away from main capital and functional region of Ranchi. In the lower portion of river Sapahi, Rukka dam is major water reservoir for water supply in Ranchi capital. The case study considered as try to prove rivers natural behavior. Thus it is a macro level field based research, there is very less possibility to acquire micro level field data. River rises from the up land of the northwest, area characterized by rocky explore and mainly forest with Sal. In monsoon season, river gives huge water mass, where as in winter it converts in a small stream. River deposits alluvial materials each year in maximum fluvial year. River morphometry and their related characteristics such as channel morphometry, drainage density and basin configuration are try to represent through different data and real environment calculation. This paper is considered to explore some specific characteristics of very small river system, that how Sapahi river system behaving with their surface configuration.
