Introduction to the Water Module Theory

The Water Module in the Tygron Platform is an implementation of a 2D grid based shallow water model, based on the 2D Saint Venant equations (see Surface Model). The module is further enhanced with infiltration, evaporation, groundwater flow and hydraulic structures.

To perform the calculations, the project area is first rasterized into a large grid of cells. Each cell has a specific quantity of water and specific hydrological parameters based on the data in the project. The total time which should be simulated is divided into discrete timesteps. Per timestep, each cell communicates with its adjacent cells to exchange water, based on it's water level, surface height, current flow direction and other factors. Accuracy and reliability is obtained by dividing the project area and simulation time into sufficiently small cells and steps, at the cost of more computation time. Take a look at the testbed water module project, available in all domains, to see some of the components of the Water Module in a project.

The Water Module enables users to implement a water model for their project which is accurate and delivers fast results. To ensure accuracy, the Water Module is repeatedly tested against multiple (internationally) acknowledged hydrological benchmarks and tests. Fast results are achieved by executing the water calculations on High performance GPU servers.

  • Supported layers in rain, flooding and ground water calculations.

  • Supported flows between the layers in rain, flooding and ground water calculations.

Calculation Models

The Water Module performs a large number of calculations to form a complete hydrological simulation. Depending on the desired viewpoint, both the overarching concepts as well as the implemented formulas can be reviewed for detailed insight into how the water overlay works.

Multiple models are implemented which in conjunction form the water model in its entirety.

Formulas

The precise calculations which govern the water overlay's simulation are many and varied, and based as much as possible on available expert knowledge.

Model related formula's:

Hydraulic structure related formula's:

Module related formula's:
