Abstract:
Hydraulic conductivity and soil moisture are the two
important components of hydrological cycle. These parameters are
quite essential in the field of agriculture and hvdrology for
irrigation and, drainage planning, ground • water
rainfall runoff modelling and for water management studies. Soil
moisture movement studies are very important for understanding the mechanism of recharge through the soil and to provide soil moisture storage data for the water balance study.
In the present study, various soil parameters considered are (:i ) measurement of field saturated hydraulic conductivity (ii) grain size distribution and (iii) soil moisture retention curves. The field tests were carried out at various locations depending upon the soil types in Malaprabha & Chataprabna sub basins. Textural analysis and soil moisture content were determined in
the laboratory of National Institute of HYdrology. Roorkee. The
in-situ field saturated hydraulic conductivity was determined by
Guelph permeameter at various locations in Malaprabha and
I1 LC ) subbasins.
