Evaluating Drainage Water Recycling Decisions (EDWRD) is a tool to estimate the potential benefits that result from capturing drainage agricultural water for reuse as irrigation, a practice referred to as drainage water recycling. This page contains various documentation and resources to help users utilize EDWRD. Materials such as tutorials and "how-to" guides are being developed and will be posted to this page. Users can access forms below to provide feedback, report an issue, and sign up to receive updates about EDWRD.
EDWRD Explanation Guide
The EDWRD Explanation Guide provides a general, conceptual description of EDWRD and the underlying processes of the modeling framework, why this tool was developed, and a brief review of how users can use EDWRD to learn more about the practice of drainage water recycling.
EDWRD Reference Guide
The EDWRD Reference Guide provides a detailed review of the souce code, including file structures, datasets, processing scripts, and functions used by EDWRD.
