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

General information

Client: Arcadis Germany
Location: Bavaria - Germany
Project duration: 2019 - 2020
Key characteristics: Precipitation-Runoff Model (PRMS), coupling with groundwater model (GSFLOW), fenland protection

Project description

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 developed 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 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. The goal of this project is protecting the largest fenland in southern Germany.

The Precipitation-Runoff Modelling System (PRMS) Software, developed by the United States Geological Survey (USGS), was used to build the precipitation runoff model. This model was then coupled with the groundwater model Modular Groundwater-Flow (MODFLOW) using the Groundwater and Surface Water Flow (GSFLOW) Software.
