Precipitation-Runoff Model of the Water System of the Danube Moss

As part of the project “Digitization, Modeling and Visualization of the Danube Water System”, Sydro Consult is working on a precipitation runoff model for Arcadis Germany for the largest fenland in southern Germany, the Danube Moss.

The fenland does not only hold flood protection functions, but it also acts as a carbon sink, as well as a biotope for rare plant and animal species. Every year, one to two centimeters of the peat soil are lost due to urbanization and drainage in the Danube Moss Area.

With the aim of protecting the fenland and ensuring sustainable agricultural use, the Water Management Office of Ingolstadt and the Zweckverband Donaumoos established the „Development Concept Danube Moss 2000-2030“.

Together, SYDRO Consult and Arcadis Germany are developing a system which consists of a numerical groundwater model, a precipitation runoff model, and a hydrodynamic-numerical model for the 420 km² area of the Danube Moss.

The Precipitation-Runoff Modelling System (PRMS) Software, developed by the United States Geological Survey (USGS), is applied for the precipitation runoff model. This model can then be coupled with the groundwater model Modular Groundwater-Flow (MODFLOW) using the Groundwater and Surface Water Flow (GSFLOW) Software. According to schedule the model should be ready by the end of 2019 and the system will be calibrated by the end of 2020, carrying out multiple calculations and simulations of different scenarios.
