Abstract

In studying EROSION and SEDIMENT supply there are few researches done in Iran using REMOTE SENSING techniques. Given the importance of accurate estimation of EROSION, lack of available measuring stations, and the existing problems with the traditional methods, it seems quite possible that REMOTE SENSING data can fill the gap. To overcome this condition in Sefid-Ab sub-basin in Haraz region, REMOTE SENSING and MPIAC model were used to estimate EROSION and SEDIMENT supply. The findings were then compared with the previous data obtained from hydrometric stations. They included the data gathered from traditional methods of topography and lithology maps, and the land use map of Mazandaran. They provided the data to to be put into GIS techniques.Concerning REMOTE SENSING techniques, the author used landsat (TM) data along with geometric correction in band 7 for lithology, a combination of bands 4 and 3 to process NDVI, bands 2 and 5 for soil moisture, and bands 4,3, and 2 as false color composite (FCC) to study the land coverage. Analysis of the data indicated 4 t/ha/y SEDIMENT in the basin which was a little different from the data obtained from hydrometric station (3.95 t/ha/y). This showed 1.3 percent difference between the traditional methods and modem SATELLITE techniques. It is concluded that using SATELLITE data can improve the quality of data in inaccessible areas where there is no ground stations. Furthermore, it saves time and money.
