This is a selection of our visualisation studies for hydrosystems:
WetUrban - Model-based management of water extremes
Based on a prototype for the city of Dresden, Germany, a methodology was developed to use digital city models as a basis for a visualisation- and interaction framework for multiple coupled hydrological and hydrodynamical process models. Specifically, we coupled a surface run-off model simulating flooding (using BASEMENT), a simulation of the sewage network (using SWMM) and a groundwater simulation (using OpenGeoSys) via open python-based interfaces. Simulation results are shown in context of a 3d city model consisting of 3d surfaces, building models, land use classes as well as additional data such as streams, groundwater wells, etc.

MOSES-Müglitz: Monitoring and Modelling Campaign
The hydrological study in the Müglitz catchment is part of the MOSES initiative (Modular Observation Solutions for Earth Systems, coordinated by UFZ) investigating the impact of extreme meteorological events on local hydrological processes. The presented visualization study is also a result of a close collaboration of the ESM and Digital Earth initiatives, combining the expertise in monitoring and modelling environmental processes in a Virtual Reality framework.

Monitoring and Modelling in Large River-Lake Systems
A virtual geographic environment for the catchment of Poyang Lake, China, with a size of 162.000 km2. The representation of rivers or lakes is enhanced by a wide range of observation data sets such as water levels or contaminant loads. Simulation results of the groundwater and the water level of flow paths of the lake itself are integrated for a holistic analysis of water and solute dynamics.

Coastal Water Management
Salt water intrusion due to overexploitation in coastal areas is deteriorating groundwater resources and heavily affecting urban areas. A suitable visualisation of the subsurface flow systems is designed to support the development of protection measures.

Numerical simulation of the water balance for the Dead Sea, showing the decrease in the natural replenishment rate of groundwater due to water used for agriculture and reduced precipitation due to climate change.

Travel times and flow paths of groundwater from its recharge area to drinking-water production wells will govern how the quality of pumped groundwater responds to contaminations. Simulating different recharge scenarios and fitting to observed water levels allows understanding the groundwater regime in the area and to estimate water quality for production.
