1. Field Measurements and Numerical Simulations of Sediment Transport in a Tidal River
Abstract : In a coastal area, an alluvial lowland river has a free connection with the open sea and its flow is bidirectional. The river basin is often highly urbanized since it hosts valuable ecosystems and natural resources. Along with the growing population, climate change and human activities (e.g. READ MORE

2. Field Measurements and Predictions of River Flow, Sediment Transport and Morphological Changes
Abstract : In an alluvial lowland river, sediment is transported in the form of suspended and bed loads. The fluvial process is the macroscopic view and long-term consequence of sediment movement. READ MORE

3. Laser Based Flow Measurements to Evaluate Hydraulic Conditions for Migrating Fish and Benthic Fauna
Abstract : Hydropower is one of the main sources for Sweden’s energy, which is clean and renewable. It is a clean energy source because no fuels are burned which does not pollute the air and it is a renewable energy source as it only uses natural water cycle for generating energy. READ MORE

4. Hydraulic Modelling of Hydropeaking in Regulated Rivers
Abstract : The role of hydropower is expected to change in the close future in the Nordic countries. In order to fulfill targets set by the Paris agreement, the reliance on low emission intermittent power production such as solar and wind power is likely to increase. READ MORE

5. Sex and symbionts : New discoveries in local and regional patterns of coral ecology and reproduction
Abstract : Coral reefs belong to the most diverse and the most threatened ecosystems on earth. Anthropogenic stressors and climate change have led to mortalities at levels unprecedented in modern times. The aims of this thesis are to investigate aspects of the corals’ ability to reproduce, disperse, adapt and survive. READ MORE
