Margaret Matter and David Tarboton February 2010 This tutorial provides some bare essentials step by step guidance on starting to use HEC‐HMS following Example 5‐1 (page 335) of Bedient et al. (2008), but presented in terms of the current version of HEC‐HMS (Version 3.5). Hydrologic Modeling System HEC-HMS. Technical Reference Manual version 3.5. Hydrologic Engineering Center. 138 p.

Wambua, S., (2004), Water privatization introducción hms es un programa que calcula el hidrograma producido por una cuenca si le facilitamos datos de la cuenca y datos de precipitaciones.1 las diversas fases de trabajo del programa pueden esquematizarse así (aparece en inglés el nombre asignado por el programa a cada fase): p neta o p efectiva infiltración, a canopy, surface, … HEC NexGen Project Begins 1990 (RAS, HMS, FDA) HEC-HMS - New GUI and UpdatesFirst Release April 1998 Version 1.1 Released April 1999 Current Version 2.0.3 HEC-HMS BackgroundPurpose of HEC-HMSImproved User Interface, Graphics, and Reporting Improved Hydrologic Computations Integration of Related Hydrologic Capabilities only SCS method is considered HEC-HMS ver. 3.5 2 Required Data All data needed for this exercise can be found in: results from Assignment 1, including the map of sub-catchments the Excel file hydrology.xlsx 3 Step by Step 3.1 Create a Project File -> New ( Ctrl + N ) Be careful of the unit give it a name, e.g. Var_Catchment 3.2 Load Your Own Map I recently installed Hec-GeoHMS 9.2.93.16 on my machine. It did not work correctly so aftre reading the forums I uninstalled all legacy components (including GeoRAS), cleaned the registry, and reinstalled. It took multiple tries but I finally got it to work with ApFramework9 3.1.0.42 and ArcHydro 1.4.0.124. Today I tried to reinstall Hec-GeoRAS Use the information given to develop a HEC-1 input data set to model this storm. Run the model to determine the predicted outflow at point B. Note that this same sample will be used later with HEC-HMS as Example 5.2. SUBBASIN NUMBER 1 2 3UH FOR SUBBASIN 3: TC (hr) 2.5 2.8 --. R (hr) 5.5 7.5 -0 0.

It is applicable to large river basin water supply and flood hydrology and small urban or natural watershed runoff. 3. Creating a Precipitation Model. Having established the physical aspects of the model, we will now address the rainfall data. From a statistical study of extreme storm rainfall data recorded at gages, tables and maps have been prepared for the whole US which specify the storm precipitation depth to be expected as a function of the return period of the event and the duration of the rainfall.
