Motivation and Objective
Urban water systems are stressed
by numerous loads resulting from urban contaminations, treated wastewater discharges, shipping and
recreation activities, just to mention a few. The numerical simulation
of flow and transport processes in such surface water systems has
become a powerful tool to make preditions about water quantity and
quality aspects for current as well as for changing conditions being
the results of engineering measures, climate or demographic
important questions deal with lake dynamics, spreading of conservative
tracers or whether treated waste water which should leave the system
can be transported in the opposite direction into the water system due
to unfavourable hydraulic conditions.
In this project, the Unterhavel water system in Berlin, Germany is chosen, which consists of a shallow lake (Wannsee) and some channels. This lake has of course limnic character and is therefore characterized by slow flow velocities.
The program JANET has been used to set up the model and the pre-processing. For the numerical simulation of the flow and transport processes, the modelling system TELEMAC 2D und 3D has been chosen. The 2D simulations deal with different hydrodynamic (mean and extreme water and discharge, bottom friction, influence of wind, turbulence) and transport conditions (different contaminants, sources, turbulence). In addition, a 3D model will be set up to investigate the 3D flow and transport processes, which are, for example important after storm events, and to compute the contamination as well as turbulence in different depths.
