Short description of training activities:
The main objective is to investigate the impact of quantity and quality of microbial produced polymeric substances (EPS) on sediment stability and flocculation dynamic as a basis to model particles-associated toxicant transport within river systems. The following methods will be learned and applied: physico-chemical (e.g. particle size, organic content, charge density) and biological parameters (e.g. EPS carbohydrates, EPS proteins, macrofauna, microalgae, bacteria) of sediment stability (using different devices, lab and in situ). The research work will be carried out on natural samples but will also include various experimental set-ups in the laboratory, including statistical evaluation. The candidate should be further introduced in already existing numerical 1D and 2D models developed at the Institute of Hydraulic Engineering. Ideally, the gained data should be implemented into already existing exposure models for environmental impact assessment.
Formation requirements:
Master in Biology, Geo-Ecology, Chemistry or related studies. Experience in field and/or laboratory is preferable. Basic knowledge in statistics and modeling is desirable
Nationality requirements: Non-German nationality, double nationality filling rule nº 2 or German nationality filling rule nº 3.
Duration of appointment: October 1st 2007 - September 31st 2010
