This document describes functionality developed to replicate algorithms used by the U.S. Army Corps of Engineers Southwest Division (USACE‑SWD). These algorithms, consisting of object methods, RPL predefined functions, and other utilities were developed as a replacement tool for the USACE‑SWD FORTRAN SUPER program. Although the algorithms were implemented for the USACE‑SWD, they are general in nature and available to all RiverWare users.

The purpose of this document is to consolidate all of the documentation specifically developed and delivered to the USACE‑SWD to describe the algorithms. This document contains documentation and implementation Help specific to the USACE‑SWD model setup and approach. But it contains links to the rest of the RiverWare Help to describe the general methods and functions. The document first presents an overview of the approach used. Then it describes the steps necessary to set up a basic simulation model and run it as a calibration. Next, there is a description of the process used to define operating policy using a RPL ruleset. Each USACE‑SWD policy is then described including the necessary method selections, how to define the policy in RPL, and detailed description of the algorithm. Finally, sections are provided to describe how to set up a yield study, use the Data Management Interface, use output and analysis tools, and how to improve performance of the modeling runs.

This document is intended to guide a user from a blank workspace through adding objects, implementing policy, and finally implementing a yield study.
