WRIMS Model Characterization for Inventory (12-4-2018WRIMS (Water Resource Integrated Modeling System)
Criterion | Explanation |
Developer
| Description | A general purpose language to implement water allocation in regulated river systems. |
Developer | California Department of Water Resources (DWR) |
Hardware computing requirements | XA Solver Hardware Key if using XA solver for optimization. |
Code language | C++ (Cbc solver) / WRESL (model implementations |
) / Eclipse (GUI environment) | |
Original application | Generalized water resources modeling system for evaluating operational alternatives in large, complex river basins. |
Public/proprietary and cost | WRIMS framework: Eclipse Public License, version 1.0 |
Physically or empirically based | Empirically based. |
Mathematical methods used | Surface water is represented as a network of nodes and channels. Model objectives and constraints are optimized via Linear Programming |
Input data requirements | WRIMS is a generalized framework. Input data will vary by application. |
Outputs | WRIMS is a generalized framework. Outputs will vary by application but generally include channel flows and allocation decisions. |
Representation of uncertainty | No explicit representation in the model output; could be implemented with multiple scenarios |
Prevalence | WRIMS is the underlying framework for Calsim, the de-facto standard for planning California Central Valley operations and Delivery Reliability Report studies |
Ease of use for public entities | The WRIMS GUI is based on Eclipse, a well-known IDE with extensive training material and documentation. Ease of use for an application of WRIMS depends on how suitable the WRESL language is for expressing the constraints of that application. |
Ease of obtaining information and availability of technical support | There is a WRIMS user group, and DWR support contacts can answer some classes of self-contained questions. |
Source code availability | Eclipse and the Cbc solver are both open source. XA Solver is proprietary. Source code for WRESL parsing does not appear to be publicly listed on the WRIMS website. |
Status of model development | WRIMS is being actively developed in support of the newest version of the Calsim model. |
