The detailed land resource inventorization of Chhatra II micro-watershed was carried out to a scale of 1:8000 using IRS imagery and cadastral map of the area as base map aided by ground truth delineation. The contiguous surface soil sampling was done from the grid, each of the size of 6 ha and profile sampling was done at identified sites considering the factors of slope, topography, physiography and land forms. The results depicted variability as well as distribution of the aforesaid physical factors within the micro watershed revealed that slope is (gently sloping), depth (shallow), texture (sandy loam) and gravelliness (gravelly), hence resulting in 23 soil phase units. The probable average runoff excess estimated based on Intensity-Infiltration method with aid of input data on rainfall events established that the average annual runoff was115.1 mm alongside average runoff producing rainfall of 388.5 mm. The Environmental flow has been accounted for from the available runoff excess with maximum (42.4 mm). Contour bunding system and graded bunding system were proposed for the arable land. Contour trenching system was proposed for non-arable land and diversion drains were proposed for Rock outcrop. Conservation structures like check dam, farm pond were proposed for drainage line treatment.
