The Hydrologic Engineering Center (HEC) has several numerical models for simulation of hydrologic and hydraulic processes in urban areas. New development and application procedures for the surface water hydrology models are described. The primary surface water hydrology model is the HEC-1 Flood Hydrograph Package. It can simulate the precipitation-runoff process in a wide variety of basins, from small urban areas to large river basins. It also has many features that facilitate its application to urban areas. The next generation of HEC-1, termed the NexGen Hydrologic Modeling System, is under development. A new model to analyze flooding in interior areas (e.g., on the land side of a levee) was just released. An older model (STORM) for urban storm water and combined sewer storage and treatment is still used in the profession, but it is not actively supported by HEC. These models (primarily HEC-1) are discussed in relation to urban hydrologic design. Future directions of the U.S. Army Corps of Engineers' new Urban Hydrology Methods/Models research work unit are also discussed.
