Abstract

The present research was carried out to study the infiltration characteristic of different land uses in selected watershed area of Konkan region Maharashtra. A grid survey was conducted in selected watershed area to access the infiltration characteristics of land uses viz. plantation land, agricultural land, pasture land and terrace land. The infiltration data collected for selected land use/cover were correlated by Kostiakov's, Kostiakov Lewis and Philip's infiltration equations. The infiltration rate for various grids ranges from 2.04 to 11.15 cm/hr with the cumulative infiltration ranges from 315.9 to 1277.16 cm. The average infiltration rate for agricultural land ranges from 2.04 to 5.09 cm/hr and the cumulative infiltration was 315.9 to 603.06 cm while the cumulative infiltration ranges from 382.23 cm to 1084.05 cm and average infiltration was 3.30 cm/hr to 7.80 cm/hr for pasture land. For plantation land the average infiltration rate ranges from 3.59 cm/hr to 11.15 cm/hr and cumulative infiltration was 549.48 cm to 1277.16 cm. The average infiltration rate for terrace land ranges from 6.47 cm/hr to 9.83 cm/hr and cumulative infiltration was 654.57 cm to 1084.05 cm. It was found that the Kostiakov's model gives almost perfect fits for the infiltration data.
