IWFM Demand Calculator (IDC) version 2015 is the stand-alone root zone simulation component of DWR’s Integrated Water Flow Model (IWFM-2015). It calculates agricultural, managed wetland, and urban water demands at river-basin scale under user-specified climatic, soil, farm-water management and land-use characteristics. It also routes
precipitation and irrigation water through the root zone, and simulates land-surface and root zone flow processes.
Participants planning to attend the next IWFM workshop are encouraged to attend the IDC workshop since the root zone module of IWFM will be covered in much more detail in this workshop.
The workshop participants will learn the basic concepts and mathematical methods used in IDC, and will have hands-on
exercises that will teach them how to build models from scratch. The software tools that are developed to aid IDC users in pre- and post-processing model data and simulation results will also be discussed.
Workshop participants will need to bring a laptop computer with several programs installed,
including MS Excel 2010 or 2013, and a powerful text editor such as TextPad. Before the workshop, participants will need to
download workshop materials (presentations, hands-on examples and guidelines for these examples) and install the IDC pre- and post-processor tools. Directions for download and installation will be provided.
Major topics will include:
- Overview of IDC-2015
- Land-use and soil moisture routing
- Simulation of water demand for “non-ponded” crops
- Simulation of water demand for “ponded” crops (i.e. rice and managed wetlands)
- Simulation of urban water demands
- Mixing dynamic demand computation with user-specified demands
- Simulation of root water uptake from groundwater
- Simulation of deficit irrigation
- Demonstration of pre-processing and post-processor tools
