The orders in this planning unit are directly proportional to watershed area , channel dimension, and stream discharge at that point in the drainage network. **Revegetation and Production potentials of high, moderate and low are based on climate, soil texture, soil depth , slope and geology . Soil textures were projected from geology , climate , vegetation and f rom i so] a ted check points . Ili gh-Moderate-I,ow are rel at ive to each other on th Is yin i t- .
