Key Features
-
Integrated software approach
SOBEK offers one software environment for the simulation of all management problems in the areas of river and estuarine systems, drainage and irrigation systems and wastewater and storm water systems. This allows for combinations of flow in closed conduits, open channels, rivers overland flows, as well as a variety of hydraulic, hydrological and environmental processes.
-
A powerful hydrodynamic 1D/2D simulation engine
The hydrodynamic 1D/2D simulation engine is the computational core of SOBEK. This engine is used in all flow programs within the SOBEK modelling suite. Thus allowing the combined simulation of pipe, river−, channel− and overland flow through an implicit coupling of 1D and 2D flow equations. SOBEK is the ideal tool for analysing the effects of urban flooding, river floods and dam break (both Sunny Day and PMF approaches).
-
Robustness of numerical operations
The hydrodynamic 1D/2D simulation engine is equipped with a very robust scheme for numerical computation. It also guarantees mass conservation, even in case of transitions through suddenly varying cross section shapes. The engine combines computations of subcritical and supercritical flow, at scales selected by the user. It handles flooding and drying of channels without the use of artificial methods (such as the Preissmann slot).
-
Numerical efficiency
The hydrodynamic 1D/2D simulation engine has a very efficient numerical solution algorithm; this is based upon the optimum combination of a minimum connection search direct solver and the conjugate gradient method. It also applies a variable time step selector, which suppresses the waste of computational time wherever this is feasible.
-
Size of models
The size of the model is only limited by the size of the internal memory of the computer used.
User Interface and Result Processing
The Graphical User Interface (GUI) is one of the most user-friendly in the market. Under the umbrella of this GUI the programmes combine into an exceptionally versatile and easy-to-use powerful suite. The GUI allows the user to visualize model input, reference data and simulation results as time series and animations of two and three-dimensional data sets. The SOBEK modelling suite is open for additional pre and post processing tools (such as the QUICKIN tool, a powerful editor of grid related data running standalone and as ArcGIS plug−in).
The input and output data from SOBEK is all readily compatible for standard GIS software as well as Google Earth, text editing software, spreadsheet applications and other commonly used software.
Ongoing Developments
The SOBEK modeling suite continues to be developed by Deltares, in association with its the worldwide user base. Current developments include:
- Delta-Shell – a new interface for all of Deltares 0D to 3D model systems.
- Flexible Mesh: an integrated engine based on 1D networks and 3D/2D layered mesh of mixed triangles, quadrilaterals, and more complex cells.
- Further developments in 2D water quality.
- Further developments in 1D morphological modeling.
