In work package 6 we focus on integrated modelling describing the filter systems for both subsurface-flow constructed wetlands and drainage filters. Focus will be on both the hydraulic performance of the filter system and the biogeochemical processes governing phosphorus retention and nitrogen transformation in filter systems.
The major research tasks include:
- Model setup for subsurface-flow constructed wetlands and drainage filters.
- Calibration and validation of the hydraulic model with respect to water transport.
- Calibration and validation of the reactive transport model with respect to the transformation of organic matter, phosphorus, and nitrogen.
- Scenario analyses in order to optimise the filter systems.
The research in this work package will benefit from both the laboratory experiments as well as the field scale experiments. The outcome will be an integrated part of the cost-effectiveness analysis of drainage filter system performance.
The research activities in WP6 start up in January 2013 and runs for two years. The work package collaborates closely with WP1 (Phosphorus sorption), WP2 (filter hydraulics and phosphorus retention), WP4 (Nitrogen Removal) and WP7 (cost-effectiveness analysis).
Projects: A Post Doc will be employed for a period of one year.
