The impact of urban groundwater upon surface water - eTheses ...

STUDY SETTING
The river along this stretch is typically 8-12 m wide, 0.2-2.0 m deep, with average dry
weather flow velocities of 0.1-0.8 ms -1 and a mean discharge at Water Orton of 397 Mld -1 .
The relatively small size of the river enables easy access for the installation of research
instrumentation.
The main potential drawback in selecting the study area was identified as the pipe-end
discharges to the surface water. There is no control on these discharges which can vary
considerably from day to day. However, this is one of the inevitable challenges when
undertaking research in an urban catchment environment.
