DSD-INT 2019 The iMOD 6 project - De Keizer
0 likes196 views
The imod 6 project aims to develop a new version of the imod software based on Modflow 6, enhancing capabilities for multi-model simulations and cooperation with USGS for robust improvements. It targets various user groups including hydrologists and water managers, focusing on modernizing software architecture and facilitating detailed regional and global modeling. Future developments will emphasize user community participation, joint investments, and integrating advanced features like parallel computation and model coupling.

- 2. Introduction • iMOD based on MODFLOW computational core • MODFLOW 6 developments urged us to start rethinking iMOD • The iMOD 6 project: development of a new iMOD version based on MODFLOW 6 • R&D and pilot projects with MODFLOW 6 • Cooperation with USGS and user groups • Elaboration architecture and start developments • Initial financing with Deltares R&D funds, but future investments from water sector will guide development efforts. iMODUserDay–DSD-INT2019 2
- 3. Main reasons for iMOD 6 development 1. Currently MODFLOW-2005 used in iMOD; MODFLOW6 provides significant advances: a. Improved (recoded) computational core b. Support for multi-model simulations, so no need to adapt MODFLOW code for use in iMOD c. Added capabilities for nested and unstructured modelling d. Full integration of SEAWAT (fres-salt) and water quality (MD3T) packages 2. Cooperation with USGS provides opportunities for more robust and sustainable enhancements (e.g. parallisation, model coupling) 3. Need to modernize and improve maintainability and support of the iMOD software in closer cooperation with the Deltares Software Centre. iMODUserDay–DSD-INT2019 3
- 4. Ambition Our ambition is that iMOD 6 becomes an open-source user interface and tool for model development and applications that combines the strengths of iMOD and the core functionality of the MODFLOW 6 computational kernel. • Facilitate an active international user community • Regarding MODFLOW6 no separate development line but developments in cooperation with USGS • Cooperation with USGS currently includes: • Parallelization of computational kernel • Interface for model couplings • Contribution to computational framework iMODUserDay–DSD-INT2019 4
- 5. iMODUserDay–DSD-INT2019 5 Interesting for the Netherlands • Modelling regional detail, including nature reserves, drinking water production, rivers • Modelling upper layers in more detail than deeper layers (e.g. based on Geotop data) • Detailed numerical modelling of piping in dikes and other local geotechnical issues • Include precise locations of abstractions in model • Combine regional and local models, e.g. with dike section • Improved performance of large scale detailed models
- 6. … and internationally • Develop multi-scale models, e.g. including river basin and delta in one model; • Model complex geological formations • Model potential solutions for drought issues • Model subsidence in delta areas • Surface water – groundwater interactions • Improved performance of global (groundwater) models iMODUserDay–DSD-INT2019 6 Subsidence Mekong Delta (Vietnam) IWRM Cauca Valley, Colombia

- 12. iMODUserDay–DSD-INT2019 12 Participation of user community • (International) user days and user meetings in the Netherlands • iMOD user forum at oss.deltares.nl • Bilateral meetings with interested parties • Joint investments • Steering group with representatives from most relevant user groups and donors
- 13. Conclusions • MODFLOW6 has the future, MODFLOW2005 will be outphased and developments focused on iMOD6; • Deltares provides initial funding from R&D funds, investments from water sector will be relevant to guide future developments • Your contributions and recommendations (e.g. regarding key needs and uses) are very welcome! iMODUserDay–DSD-INT2019 13 • In 2019: • Identification of user needs and priorities for developments • Architecture and project plan for developments 2019 (minimum viable product) • Identify interest for joint investments (possibly combined with govermental subsidies) • In 2020 focus on: • MODFLOW6 (structured) in iMOD5 • New user interface for unstructured and nested models • MODFLOW6 coupling with (Meta)SWAP • Development iMOD6 Toolbox for modeller • Maintenance and support
