Frias, E. Geomorphology alteration effects over Kävlinge River Basin. An analysis using a physically-based hydrological model. Master Thesis, TVVR 20/5018, Dep. of Water Resources Engineering, Lund University
After running the simulations, the models show a decrease in the water level of 0.02 m and a discharge peak reduction of 2 m3/s and a delay in the presence of the Max.
This thesis focuses on the case study over the Kävlinge catchment located in
the south of Sweden, and mainly in the Kävlinge river. This river, which is the
mainstream of the catchment, has been subject to modifications due to
agricultural activities. Such modifications, like straightening or increasing the
depth and channeling sections of the river, will affect the river’s
hydrodynamics. These interventions are often made to reduce the impacts of
fluvial floods in the presence of extreme rainfall events. Such floods can be
expected to occur more frequently in the future because of climate change.
However, these modifications may also affect soil erosion and can have other
adverse effects on the river ecosystem. This work will use a physics-based
hydrological model to simulate the hydrodynamics conditions of the river and
the basin, along with the effects of river straightening. These are compared
with the modeling of the original river course. This study is a starting point for
further analysis and research aimed at improving the ecological conditions of
the Kävlinge river basin.
