Criterion | Explanation |
General Description | The Delta Island Consumptive Use (DICU) model simulates the island monthly consumptive usesuse, corresponding island water supplies, and the channel and channel diversion, seepage and return flow volumes for 142 islands in the Sacramento – San Joaquin Delta, using the information of . The calculation is performed using information on land use, historical precipitation, and agricultural activities. The model is used to estimate historical agricultural flows, future planning agricultural volumes, and the estimate values were assigned to nodes in DSM2. The DICU model provides time series values of diversiondiversions, drainage and seepage at 257 locations throughout the Delta at monthly basisa monthly time step. |
Model Domain | Same The model domain is the same as DSM2. |
Developer | California Department of Water Resources (DWR) Planning Division |
Hardware computing requirementsNone | The model runs on Windows based computer platforms. |
Code language | FORTRAN |
Original application | The model was developed for the Delta. |
Public/proprietary and cost | Public |
Physically or empirically based | Physically based |
Mathematical methods used | Water The water balance for each sub-area consists of the following terms: TCU = CUp + CUs + CUaw + dSM = ET + dSM |
Input data requirements | Main The main data inputs are:
|
Outputs | Diversions, seepages and returns of DSM2 nodesModel outputs include diversions, seepage and return flows at DSM2 nodes. |
Pre-processing and post-processing tools | None/unknown. |
Representation of uncertainty | None/unknown. |
Prevalence | Frequently used in the Delta, and in conjunction with the DSM2 model. |
Ease of use for public entities | Mass balance model, should be easy to use for public entities |
Ease of obtaining information and availability of technical support | Available Technical support is available upon request from DWR. |
Source code availability | Available upon request. |
Status of model development | The model is well maintained and actively updated. |
Challenges in integration | Has The model has been integrated with DSM2. |
