Projected Elevation

Last Modified: 2025-10-26 14:04:50.662

The objective of this section is to verify and validate the HEC-ResSim operations feature: Projected Elevations. This is accomplished by creating a simple ResSim model and several operation sets with and without Projected Elevations to compare results. This document covers Projected Elevations used in: Rules, Zone Definitions, IF Blocks and Diversions. Additional model set up is required to verify and validate Projected Elevations used in State Variables and Scripted Rules.

Release Allocation

The objective of this section is to verify and validate the HEC-ResSim operations feature: Release Allocation. This is accomplished by creating a simple ResSim model and several operation sets with different Release Allocations. This document covers the following types of Release Allocations: Balanced, Sequential, Stepped and Release Allocation using IF BLOCKS.

Overrides

This is the list of HEC-ResSim's operational calculations to be verified and validated. Initial test cases have been developed for three of these operational features: Projected Elevations, Release Allocations, and Overrides. Documentation of test results follows. Further expansion on these tests can be used to validate more complex scenarios that go beyond the basic calculations.
