The document details various treatment measures for springshed development, focusing on structural, vegetative, and agronomic management strategies. It outlines specific dimensions and volume requirements for staggered contour trenches based on slope, as well as additional methods such as check dams, rainwater harvesting, and controlled grazing protocols. The integrative approach aims to enhance recharge zones across cultivated and uncultivated lands to support spring conservation.
