Conclusions:

- Subcatchments are appropriate units for spatial analysis

- Hydrological parameters should be standardized for comparison

- Urban areas proximity to river channels is important metric

- Hydrodynamic modeling can be used to trace the pollution

- Reservoir has a lacustine zones with a swirl flow which extends

the retention time
