| Description: |
Abstract This thesis focuses on two lakes (Pyykosjarvi and Kuivasjarvi) located in a suburban area of Oulu, Finland. This analysis aimed to model water circulation between two lakes and provide possible solutions for reducing the residence time from one lake to another, eventually improving the water quality, as these lakes suffer water quality problems due to poor drainage. Two-dimensional hydrodynamic modeling was applied to resolve this problem by implementing channel modification to the actual terrain. Modified terrain is then analyzed for the hydrological response of the basin (as discharge) to short rainfall of 5, 10, 50 and 100 years return period to observe the catchment response to changes. It is evident from the results acquired through hydrodynamic modeling that channel modification can reduce residence time between two lakes. Moreover, catchment response to rainfall scenarios showed exceptional results with almost no flooding with changes introduced compared to the actual conditions. These modifications can help improve water quality in both lakes as a conveyance in the system ameliorates. see all
