Wang, ed.: American Society of Civil Engineers, New Orleans, August 14-18, 1989, pp. 260-2652 Lew, Melvin, 1998, Operation of Hydrologic Data-Collection Stations by the U.S. Geological Survey in 1997: U.S. Geological Survey Open-File Report 97-832, p.14. These data have been multiplied by a coefficient of 0.657 based on the relation between the red and tan bars for the period 1985-1993 in an attempt to render Lew's data comparable to the blue and red bars. Data depicted by the blue bars were dervied from the National Water Information System or its predessesor. Data depicted by the red bars, of unknown origin, also appear to be approximately derived from the National Water Information System. Almost half of the sediment stations operated in 2000 are in Puerto Rico.(J ohn R. Gray and Roger K. Chang, USGS, OSW, October 2000)

Some RESIS-II Findings*Some RESIS-II Findings* • The use of a GIS has enabled a more detailed
study of reservoir sedimentation data and rates.
• Soil erodibility was found to be the most influential factor affecting reservoir sedimentation rates – A proxy for land-use?
• A negative relation was found between mean annual rainfall and sedimentation rates – Annual rainfall a proxy for land cover?
• A positive relation exists between storm intensity and sedimentation rates
