Soil erosion and sediment yield are among the most challenging topics in environmental science community. Locating sources is a crucial factor watershed management, through which production can be controlled at lower cost better performance. The fingerprinting method an accurate approach to determine source of watershed. This study aimed investigate use various physical, chemical, biological attributes soil watersheds upstream Anzali Wetland. A series were identified studied watershed, including undisturbed degraded rangelands, forests, rice fields, tea gardens, gullies, river banks. In this study, 93 samples collected, 14 from outlet 79 sources. total 35 measured. contribution each was determined using statistical technique stepwise diagnostic analysis. Some selected as tracers, enzyme phosphatase, organic carbon, very fine coarse sand, magnesium, mercury, cadmium. results revealed two primary i.e., riverbanks (69.17%) gullies (12.14%). Based on outcome inflow into wetland significantly reduced by controlling bank gully appropriate measures.
