Overview

HEC-ResSim (Reservoir System Simulation) is designed to simulate dam operations at one or more reservoirs, diversions, and locks and dams for a variety of operational goals and constraints. HEC-ResSim is fundamental to the CWMS software suite, as it simulates real-time dam operations to meet approved Water Control Plan (WCP) rules such as flood management, low flow augmentations, hydropower, system operations, and guide curve operations. In addition to providing Water Managers (WM) with simulation that meets approved WCPs, HEC-ResSim provides the capability for WMs to enter operational overrides based upon institutional knowledge and WM judgement. This allows them to refine operational forecasts and/or to evaluate impacts of deviating from WCPs due unforeseen circumstances, such as outlet structure outages, temporary restrictions either upstream or downstream, or emergency situations.

Accomplishments

The HEC-ResSim team worked on completing tasks necessary to release HEC-ResSim 3.5 in early FY24.

Concurrently, the team advanced development of HEC-ResSim 4.0, with targeted release for FY24, including:

  • Water Quality modeling
  • Smart diversions
  • Migration to HEC Monolith

Field Support and Technology Transfer

  • Monthly working sessions on Microsoft Teams
  • CWMS HEC-ResSim Scripting Workshop (MMC)
  • Reservoir System Analysis with HEC-ResSim PROSPECT Course
