Development of single rain storm erosivity models in central plateau and hill zones for Chitrakoot district

In this paper, the erosivity studies were conducted in Chitrakoot district coming under the central plateau and hills agro-climatic zone to verify the quality and representativeness of the results generated and to provide a greater understanding of the rainfall erosivity. Chitrakoot district lies between the latitudes 24° 48’ to 25° 12’ north, longitudes 80° 58’ to 81° 34’ east and elevation range of 134-252 m from mean sea level. The geographical area of Chitrakoot district is 316400 km2. 15-years precipitation (daily based) data from 1999 to 2013 were used for calculating equations and respective determination coefficient (R2). The daily rainfall erosivity in Chitrakoot ranged from 39.846 to 61.841 MJ mm/ha/h. Rainfall erosivity indices, based on intensity and the amount of rainfall, were computed for all precipitations. The lowest values were found in June and the highest values were found in the August in the Chitrakoot district. These equations can be useful to map rainfall erosivity for the entire area.
