Abstract
A watershed is an area that drains surface water to a common outlet. It is hydrologic unit that is often used for the management and planning of natural resources. The study of slope in a natural unit like watershed has become an important aspect of geomorphology. The present study aims at analyzing the slope characteristics of Porandalar Watershed. A glance over the frequency distribution of slope provides uneven distribution of slope throughout the watershed. About 19.35% of the total area is level land which is found in the northern part of the study area. The very steep slope category can be found in the middle of the watershed as a small patch. Almost 57% of total study area is covered by moderate to steep slope zones.
