CS(AR)-32/98-99: Representative basin studies: Hydrological soil classification of Suddagedda basin, Andhra Pradesh

Abstract

Hydrological soil classification at Suddagedda basin of Andhra Pradesh has been made based on field and laboratory experiments on the soil samples. Hydraulic conductivity of the soil in the basin has been determined using Guelph permeameter at two depths at various sites (17 sites). The contour map of the field saturated hydraulic conductivity is presented in the report. To facilitate inter-comparison, the reported values of infiltration at the corresponding sites in the basin are also presented. Soil properties together with other information have been presented and the basin soil has been grouped into different hydrological soil groups. The findings of the study can be used as a reference for hydrological studies that may be done in future. The study was conducted as a part of the representative basin studies of the Deltaic Regional Centre, Kakinada of National Institute of Hydrology.
