The HEC-HMS Applications Guide (2002) suggested adjusting the initial and constant loss rate parameters in order to calibrate the model. The initial and constant losses were estimated from soils data in Bexar County and with help from Table 5-1 in the HMS Reference Manual (2000).

Engineering Center for their HEC-HMS software manuals, technical theory documents and support center which have been crucial to the project. Also, the online

input required for the transform model is the lag time and HEC-HMS technical reference manual suggest the usage of . 0.6 times the time of concentration for ungauged watersheds. The HEC-HMS user manual suggests how to model storm rainfall depth versus drainage area relationships, based on Figure 15 in the National Weather Service’s Technical Paper No. 40 which HEC-GeoRAS – The geographic extension for HEC-RAS. An ArcView extension requiring ArcView 3.x and 3D analyst. HEC-HMS – Hydrologic Modeling System of the Hydrologic Engineering Center of the U.S. Army Corps of Engineers (USACE). HEC-RAS – HEC River Analysis System. B-2 The HEC-HMS program is much more complicated than the HEC-1 program and will require a longer learning curve to use effectively.

This document is the technical reference manual for the Hydrologic Modeling System (HEC-HMS). The program is a product of the US Army Corps of Engineers' research and development program, and is produced by the Hydrologic Engineering Center (HEC). The program simulates precipitation-runoff and channel routing processes, both natural and controlled.

The HEC-HMS model simulates rainfall-runoff processes in a dendritic (single outlet) watershed. The model simulates the individual fluxes of the hydrologic cycle, such as snow-melt, infiltration, evapotranspiration, base flow, and channel routing.
