Typical tropical climate dynamics of the basin. The various parameters dominates the region having hotter summers to reflect the exact mathematics behind the water colder winters. The study area shows a general low dynamics relating river and groundwater. The study relief but at places having steep slopes.

It is a part of Pahuj river basin dendritic pattern and trellis pattern. The tributaries located in the Jhansi district of Uttar Pradesh, flowing themselves suggest being on hard rock 2 India.

The study area receives rainfall an average of sensing and GIS have been proved to be efficient about 880.0 mm annually having the mean annual tools in drainage delineation and hence the temperature 38° C. The elevation varies between morphometric parameters were computed using 214 m in the North-East to 375 m above mean sea ArcGIS 10 software for a detailed study. The level in the center of the watershed at ridge, above drainage pattern of the study area is dendritic and 300 m above mean sea level at South-West. some part of the study area is trellis pattern with stream orders ranging from I to V orders. Drainage density ranges from <1 to >5 km/km2 suggesting coarse to moderate drainage texture. The values of bifurcation ratio ranging from 2.00 to 4.71 indicate that the Pahuj watershed fall under normal basin category.

Introduction The Pahuj river, a tributary of Chambal river, basin lies under a geographic location between 78°18’10.12” to 78°33’13”E longitudes and 25°19’15.85” to 25°31’45.26”N latitudes.

Review of Literature delineating the study area and exporting the information to DEM format. The SRTM DEM data Water, one of the vital natural resources for was imported to ArcGIS 10, based on these data agricultural, is becoming deficient because of over- slope, aspect and contour map for the watershed exploitation, poor groundwater recharge, was prepared. The drainage network of the immoderate use etc. Therefore, the study of watershed was prepared from Survey of India morphometric characteristics assumes greater toposheets through ArcGIS 10 software. Based on significance in developing the surface and the drainage order, the channels were classified groundwater resources more particularly in Central according to drainage order following (Strahler, India. (Sahu, et.al, 2017) 1964). Watershed parameters, such as, area, Development of a drainage system and the flowing perimeter, length, stream length, and stream order pattern over space and time are influenced by was also calculated. Later, these parameters were several variables (Horton 1945; Leopold and used to determine other influence factors, such as Maddock 1953; Abrahams 1984). bifurcation ratio, Stream length ratio, stream “Morphometry is the measurement and frequency, drainage density, elongation ratio, mathematical analysis of the configuration of the circulatory ratio, form factor.
