Infiltration analysis using runoff plots
1990
Das, Bibhudutta
Infiltration is an important phenomenon to be considered in modelling runoff, soil erosion and soil moisture balance. Two physically based infiltration models for layered soils and variable rain intensity were experimentally verified with parameters measured directly from the soil. The models were based on the Green-Ampt-Mein-Larson approach and Richards' Equation. Two natural storms were used to predict the infiltration and runoff behaviour of the soil. The models performed satisfactorily under the field conditions. Using these models the effect of soil management practices on infiltration and runoff were analyzed. The infiltration volumes predicted by the Green-Ampt-Mein-Larson (GAML) model were nearer to the observed field values. The study was conducted using runoff plots at the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), India.
