ABSTRACT
Sediment yield depends on the erosion processes at the sediment source and on the efficiency of the system that transports the sediment to the point of measurement. The sediment yield usually differs at different locations in a stream system (USDA, 2008). Many interrelated factors affect sediment yield. Knowledge of each of these factors is important when
1. Evaluating downstream sediment damages 2. Determining the location and extent of sediment sources so effective con-
trols can be planned and installed 3. Evaluating the relative contribution of the various sources to current and
future sediment yield 4. Determining the sediment storage requirement for designed proposed
structural works of improvement
This chapter presents several procedures for determining sediment yields and interrelated factors such as sediment sources and delivery ratios.
