Analysis of existing immission data

 

The project starts by analyzing the body of data that is available in the 3 investigated regions. This comprises hydrological data, chemical and biological measurements in river, emission data for WWTP. These data will be checked for its adequacy to calculate accurate and precise substance flows and a first flow scheme will established and checked for consistency. The weaknesses in the current monitoring schemes will be uncovered by this action

Design and execution of exemplary monitoring campaigns


Collecting monitoring data that will allow the calculation of accurate and precise substance flows is critical for the assessment of reference immission  situations and the proof of success for management measures. After the evaluation of the management programs in the 3 regions, taylor-made operational monitoring campaigns will be designed and implemented for specific measures. Reduction of overflow emissions need a different monitoring approach than nitrate pollution via groundwater for instance.

Application of loading models


Loading models will be applied to estimate emissions from point and diffuse sources in selected catchments in the 3 participating regions. Sources considered include WWTP and industrial emissions, combined sewer and stormwater overflows as well as soil erosion and groundwater input. Ertfverband’s own “DatenFluss” load simulator and SOBEK EM will be used for this purpose.
Responsible partner: Erftverband(Datenfluss) & Delfland waterboard (SOBEK EM)

Application of water quality models

 

Following the characterization of the immission situation, the impact on water quality will be modeled with DWA WQ and SOBEK WQ. Modelling will include mainly eutrophication and oxygen status but also metal and xenobiotic fate within the water courses. Predictions on effects on biological indices will be peformed.

Uncertainty analysis for loading and water quality modeling

 

Although models suggest deterministic results, they contain a lot of uncertainty linked to input parameter variability or structural bias in model algorithms. This uncertainty needs to be quantified and communicated as a part of the decisional process. Discrete and spatial data will be evaluated according to state of the art methods and Monte-Carlo realizations will be fed to loading and water quality models for uncertainty analysis. Scenarios in the 3 regions will equally be tested for their uncertainty.

Dissemination

 

M3 will produce a series of reports and publications in journals as well as a book to disseminate the expertise gained in the project. This information will be available in the download section.

M3 will organize 4 specific workshops with stakeholders on aspects of the project:

Workshop 1: Immission data analysis and monitoring design (Spring 2010)
Workshop 2: Loading models as support for river basin management planning (Spring 2011)
Workshop 3: Water quality modeling in river ecological status characterization (Spring 2012)
Workshop 4: Uncertainty in river basin modeling practice (Autumn 2012)
