Abstract: The objective of this paper is to present a scientific method based on multiple linear regression analysis between the sediment yield per square mile and a number of physically realistic and easily-obtainable physiographic, hydrologic and meteorologic factors known to influence sediment yield. Analysis indicates that the dependent variable, namely the sediment yield per square mile is highly correlated with total storm precipitation or peak flow, drainage area size, relief ratio, and a non-dimensional fire factor. Best results were obtained with logarithmic transformation of all variables. Two regression equations, one for drainage area size up to 3. 0 mi**2 and the other for drainage areas greater than 3. 0 mi**2 are presented.
