CAUSATIVE FACTORS AND VARIATION OF SEDIMENT YIELDS IN KENTUCKY.

Precipitation, topography, runoff, soils, and land use are the major causative factors of sediment yield in Kentucky. The variability and interaction of these factors directly affects the amount and type of sediment yields. Sediment yield and size data were collected during 1942-45 and 1951-81 throughout the five major physiographic regions of Kentucky and at selected stations on the main stem of the Ohio River. The highest average annual suspended-sediment discharge, the average percent sand in suspended sediment, and the bedload discharge for selected stations were noted in the article.
