2024 USACE Tulsa District Workshop: Reservoir Sedimentation Analysis using HEC-HMS
2024 USACE Tulsa District Workshop
Reservoir Sedimentation Analysis using HEC-HMS
28-30 August 2024
Tulsa, OK
Training Description:
The Hydrologic Engineering Center (HEC) of the U.S. Army Corps of Engineers (USACE) is pleased to introduce the incorporation of dynamic reservoir volume reduction, specifically reservoir sedimentation analysis, into its esteemed hydrologic software, HEC-HMS. This significant upgrade empowers HEC-HMS with the capability to accurately compute long-term reservoir sedimentation, both pre- and post-wildfire events. Through sediment trap efficiency methods and dynamic reservoir volume reduction techniques, HEC-HMS now enables continuous updating of elevation area and elevation storage curves, facilitating the simulation of short- and long-term sediment deposition in reservoirs. This workshop aims to leverage these advanced capabilities within HEC-HMS to calculate reservoir volume reduction in both unburned and burned watershed areas.
Objectives:
- Gain an understanding of the dynamic reservoir volume reduction process and empirical sediment trap efficiency equations incorporated in HEC-HMS.
- Acquire hands-on experience in developing a comprehensive long-term reservoir sediment model, including parameter estimation, calibration, and utilization of HEC-HMS.
It is recommended that you use HEC-HMS version 4.13-alpha or higher version and HEC-DSSVue version 3.3.29 for the class. You do not need administrative privileges to install HEC-HMS and HEC-DSSVue. Download HEC-HMS version 4.13 alpha (special version for this Workshop) from here (HEC-HMS-4.13-alpha-win-x64.zip). Download HEC-DSSVue version 3.3.29 from this page, https://www.hec.usace.army.mil/software/hec-dssvue/downloads.aspx. Then use 7-zip and unzip the files to the C:\Programs directory on your computer (you should have a folder named HEC-HMS-4.13-alpha within the C:\Programs directory). Then you can pin HEC-HMS.exe and HEC-DSSVue.exe to your taskbar and open these programs by clicking on the icons.
