“…While showing a good morphological quality (Scheifhacken et al 2011), the river is strongly polluted with inputs from agriculture, industry, urban areas and mining activities Delfs et al 2011;Ertel et al 2011;Tavares Wahren et al 2011). Two general research questions are (1) can the lessons learned from the newly formed German states be useful for improving the water quality in the Bug Area and (2) what are the consequences for the implementation of the EU Water Framework Directive as the Bug River crosses the EU border.…”

“…This type of research is further closely related to sustainability research in sensitive regions [e.g. in Brazil (Lorz et al 2011;Vasyukova et al 2011), Saudi Arabia (Pfletschinger et al 2011), Oman (Grundmann et al 2011;Schütze et al 2011); Mongolia (Sigel et al 2011;Horlemann and Dombrowsky 2011), and the Western Ukraine (Tavares Wahren et al 2011;Scheifhacken et al 2011)]. Correlations between hydrological processes and compartments as well as urbanization dynamics can become quite complex.…”

This paper presents the hydrological coupling of the software framework OpenGeoSys (OGS) with the EPA Storm Water Management Model (SWMM). Conceptual models include the Saint Venant equation for river flow, the 2D Darcy equations for confined and unconfined groundwater flow, a two-way hydrological coupling flux in a compartment coupling approach (conductance concept), and Lagrangian particles for solute transport in the river course. A SWMM river-OGS aquifer inter-compartment coupling flux is examined for discharging groundwater in a systematic parameter sensitivity analysis. The parameter study involves a small perturbation (first-order) sensitivity analysis and is performed for a synthetic test example baseby-base through a comprehensive range of aquifer parametrizations. Through parametrization, the test cases enables to determine the leakance parameter for simulating streambed clogging and non-ocillatory river-aquifer water exchange rates with the sequential (partitioned) coupling scheme. The implementation is further tested with a hypothetical but realistic 1D river-2D aquifer model of the Poltva catchment, where discharging groundwater in the upland area affects the river-aquifer coupling fluxes downstream in the river course (propagating feedbacks). Groundwater contribution in the moving river water is numerically determined with Lagrangian particles. A numerical experiment demonstrates that the integrated river-aquifer model is a serviceable and realistic constituent in a complete compartment model of the Poltva catchment.

“…The IWAS project is aimed at integrated water resources management (Kalbus et al 2011) in different hydro-climate sensitive regions, Ukraine Tavares et al 2011;Ertel et al 2011;Scheifhacken et al 2011), Saudi Arabia (Pfletschinger et al 2011), Oman (Grundmann et al 2011;Schütze et al 2011), Brasil (Lorz et al 2011Vasyukova et al 2011), Mongolia (Vetter et al 2011;Hartwig et al 2011). Cross-cutting projects are focussing on modeling, socio-economy (Schanze et al 2011;Sigel et al 2011) and capacity building (Horlemann and Dombrowsky 2011;Leidel et al 2011).…”

The IWAS-ToolBox: Software coupling for an integrated water resources management

Numerical modeling of interacting flow and transport processes between different hydrological compartments, such as the atmosphere/land surface/vegetation/ soil/groundwater systems, is essential for understanding the comprehensive processes, especially if quantity and quality of water resources are in acute danger, like e.g. in semi-arid areas and regions with environmental contaminations. The computational models used for system and scenario analysis in the framework of an integrated water resources management are rapidly developing instruments. In particular, advances in computational mathematics have revolutionized the variety and the nature of the problems that can be addressed by environmental scientists and engineers. It is certainly true that for each hydro-compartment, there exists many excellent simulation codes, but traditionally their development has been isolated within the different disciplines. A new generation of coupled tools based on the profound scientific background is needed for integrated modeling of hydrosystems. The objective of the IWAS-ToolBox is to develop innovative methods to combine and extend existing modeling software to address coupled processes in the hydrosphere, especially for the analysis of hydrological systems in sensitive regions. This involves, e.g. the provision of models for the prediction of water availability, water quality and/or the ecological situation under changing natural and socio-economic boundary conditions such as climate change, land use or population growth in the future.
