ARMSED (Army Multiple Watershed Storm Water and Sediment Runoff), a Runoff and Sediment Yield Model for Army Training Land Watershed Management. Volume 1. Parameter Estimation Guide.

摘要

Army land managers and environmental planners must estimate runoff and sediment yield from small, ungaged watersheds on Army training lands to assess the condition of the lands and to evaluate alternative erosion control plans. The U.S. Army Construction Engineering Research Laboratory (USACERL) developed the Army multiple watershed storm water and sediment runoff (ARMSED) simulation model, which is based on the MULTSED model and has been adapted for Army use. ARMSED is a single event, distributed, deterministic simulation model that operates on MS-DOS compatible microcomputers with 512 K RAM. A 10-megabyte hard disk is recommended. This report provides guidance and documentation for ARMSED users. This volume contains guidance for selecting and estimating the parameters and values needed as input for the model. Volume II describes the various subroutines of ARMSED and the modifications that have been made to arrive at the current version. As the user base for ARMSED expands, the model will be updated and modified to incorporate new data and ideas. (sdw)
