16. Data-driven analysis of water and nutrient flows: Case of the Sava River Catchment and comparison with other regions
Sammanfattning : A growing human population and demands for food, freshwater and energy are causing extensive changes in the water and biogeochemical cycles of river catchments around the world. Addressing and investigating such changes is particularly important for transboundary river catchments, where they impose additional risk to a region’s stability. LÄS MER
17. Marine Current Resource Assessment : Measurements and Characterization
Sammanfattning : The increasing interest in converting energy from renewable resources into electricity has led to an increase in research covering the field of marine current energy, mainly concerning tidal currents and in-stream tidal turbines. Tides have the advantage of being predictable decades ahead. LÄS MER
18. The influence of multiscale hyporheic flow on solute transport : Implications for stream restoration enhancing nitrogen removal
Sammanfattning : Stream water that flows into and out of streambeds is called hyporheic exchange flow (HEF).It continuously interacts with groundwater and thereby affect the water quality of local streamreaches as well as downstream recipients by providing an environment where solutes andenergy can be retained and degraded.

19. Automation of underwater operations on wave energy converters using remotely operated vehicles
Sammanfattning : In the last fifteen years, the Division of Electricity at Uppsala University has been developing a wave energy converter (WEC) concept. The concept is based on a point-absorbing buoy with a directly driven linear generator placed on the seabed. LÄS MER
20. Morphology of Tigris River inside Baghdad City
Sammanfattning : Tigris and Euphrates rivers represent the artery of life in Iraq. Tigris River rises from Turkey and flows toward the southeast to enter Iraq. It drains a catchment area of 473 100 km² of which about 58% lies in Iraq. In this study the reach, about 50 km long, of the river inside Baghdad was been studied. LÄS MER
