A major functional extension of RIBASIM: a model package for simulating the time varying characteristics of river basins under varying hydrological conditions. Based on experiences with applications in Egypt, India, Tashkent and China, the functionality of RIBASIM has been considerably extended to enable, amongst others:
- simulation of groundwater water balances, including exchange with rivers and other aquifers
- identification of linkage types for different kinds of surface water and ground water flows
- back water off takes for surface water reservoirs
- hedging zones in reservoirs, operation by volume and by priority
Beyond version 6.3
In 2001 a long term plan has been drawn up. Based on Delft-WISE technology, RIBASIM and SOBEK will eventually become members of the same product family. The plan foresees:
- shared simulation engines for land-based hydrology (irrigation, rainfall-runoff, emissions); • on-line coupling of land-based hydrology with river system network algorithms;
- complementary simulation capabilities for the river system network algorithms (RIBASIM: water allocation and flow routing; SOBEK-CF: hydrodynamics);
- shared components (Delft-WISE and native) for GUI, workflow support, data management and data-engine;
- shared or complementary keyword-based database.
To co-operation with the SOBEK-team has been intensified, resulting in:
- joint Graphical User Interface development
(Delft-SHELL, NETTER)
- extensions of Delft-TOOLS
- joint irrigation/hydro-agricultural modelling
After investigation of various alternatives, the OMIS-crop planning algorithm was chosen as the basis for irrigation modelling. This algorithm will be wrapped in a library, and linked to the SOBEKRR module. Finally, investigations have started in 2001 to apply the Delft-IO library to on-line coupling of the water allocation algorithm with the hydro-agricultural crop module (OMIS).
