*The stream order system is a method to analyse drainage-basin characteristics . 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
ated (_heck points . High-Moderate-Low are relative to each other on this unit .
