Process description
Processes represented by model: | The integrated multi-processes include:
|
Key physical parameters & equations: |
|
Length scale & resolution constraints: | lenth sscale ranges from meters (for example dam break problems) to thousands of kilometers (for example large watershed simulations). |
Time scale & resolution constraints: | Time scale ranges to seconds (for example, dam break problems) to tens of years (for example real time simulations of large watersheds). |
Numerical limitations and issues: | Covergency and instabiliy may occur depending the stiffness of the problems. |
Testing
Available calibration data sets: | A total of 17 flow problems and 15 water quality transport problems are presented in WASH123D. These example problems can serve as templates for users to apply WASH123D to research problems or practical field-scale problems. For the 17 flow examples, the following objectives are achieved: Seven to demonstrate the design capability of WASH123D using seven different flow modules; Four to show the needs of various approaches to simulate various types of flow (critical, subcritical, and supercritical) in river networks and overland regime; and Five to illustrate some realistic problems using WASH123D. |
Available test data sets: | A total of 17 flow problems and 15 water quality transport problems are presented in WASH123D. These example problems can serve as templates for users to apply WASH123D to research problems or practical field-scale problems. For the 13 water quality transport problems: six examples for one-dimensional transport, four examples for two-dimensional transport, and three examples for three-dimensional transport. These examples are used to achieve the following objectives:

User groups
Currently or plans for collaborating with: | I am currently collaborating with ERDC, US Army Corps on the continuing development and improvement of WASH123D. I am also collaborating with several university researchers on the application of the model to field watesheds. I am willing to collaborate with any users either in the further development and modification of the model or in the application of the model to field scale or laboratory scale problems. I am also willing to collaborate with anyone to develop graphical interfaces to prepare input and to visualize output of this model. |
