Abstract : The Hydrologic Engineering Center, HEC, has several numerical models for simulation of hydrologic and hydraulic processes in urban areas. This paper will focus on new developments and applications procedures for the surface water hydrology models. 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 which facilitate its application to urban areas. The next generation of HEC-1, termed the NexGen Hydrologic Modeling System, HMS, is currently 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 not actively supported by HEC These models (primarily HEC-l) will be discussed in relation to urban hydrologic design. Future directions of the Corps new 'Urban Hydrology Methods/Models' research work unit will also be discussed.
