Abstract: The results of tests by the U.S. Army Corps of Engineers District, Los Angeles (LAD), became a major part of the Corps' EM 1110-2-1601, Hydraulic Design of Flood Control Channels. Over a 10 year period, the computer program, WASURO, was developed by LAD which utilized many of the criteria of the EM and the experience of LAD engineers. This program was an integral part of a design effort for flood control channels for the Rio Puerto Nuevo Flood Control Project in San Juan, Puerto Rico. The design considered flow junctions, flow under bridges with piers, minimum channel radius of curvature, transitions, air entrainment, divider walls, and location of hydraulic jumps; all under supercritical flow conditions. This paper discusses the criteria that were followed during the analysis and design.
