5. SPHY/WFlow hydrology
 Modeling of Rainfall-Runoff process
 Discharge in the system
Water availability

6. RIBASIM - water resources
 simulate supply and demand under different
management options

7. RIBASIM - water demand

10. Aquifers

11. Groundwater abstraction

12. Interaction Ribasim - iMOD

13. Delft-FEWS
 Tool for managing forecasting processes
 Managing pre- and post-processing software
 handling time series data
 Include adapters
 Project database

19. Types of ground water – surface water
interaction
1. Continuous draining river
2. Periodically changing from
drainage into infiltration
3. Continuous Infiltrating
river (hydrological
connection)
4. Through flow situation
5. Continuous infiltration
(surface water and
groundwater disconnected)

20. Stakeholder Engagement & Collaborative Modeling
