1. Dynamics of nutrient mass transport : A river basin evaluation
Sammanfattning : Human settlements and activities can dramatically change and accelerate the rate of eutrophication in a river basin. An undesirable increase in the input of nutrients, e.g. phosphorus and nitrogen, to a surface water causes adverse water quality conditions. LÄS MER
2. Tropical cyclone induced extreme wind, rainfall, and floods in the Mekong River Basin
Sammanfattning : Increasing magnitude and frequency of climate extremes under global warming are threatening the socioeconomic development in many parts of the world. The Mekong River Basin (MRB) is a good example for how climate extremes can affect society, as the transboundary MRB has experienced hydroclimate changes and fast socioeconomic development during the past decades.

3. Iron in the Lena River basin, NE Russia : Insights from microscopy, spectroscopy and isotope analysis
Sammanfattning : Iron is an important mediator of biotic and abiotic processes on the Earth’s surface, being an electron acceptor in organic matter degradation, a surface for organic matter and trace element adsorption, and a required element for enzymatic processes during primary production. Yet, the role of iron as a mediator of carbon and trace element cycling in high latitude, permafrost-dominated regions remains poorly investigated. LÄS MER
4. Hydrological modeling as a tool for sustainable water resources management: a case study of the Awash River Basin
Sammanfattning : The growing pressure on the world‘s fresh water resources is enforced by population growth that leads to conflicts between demands for different purposes. A main concern on water use is the conflict between the environment and other purposes like hydropower, irrigation for agriculture and domestic and industry water supply, where total flows are diverted without releasing water for ecological conservation.

5. Scenarios for Flood Risk Management Strategies Integration in Mozambique : A backcasting approach for the case of the Limpopo River Basin
Sammanfattning : Flood risk management strategic planning with long-term perspectives is a complex problem, for which the solution requires a multidisciplinary and multi-paradigm approach. A significant dimension of this complexity arises from the need to include or add a participatory mode to the solution process, which amounts to a requirement that all stakeholders, ranging from decision makers to experts and beneficiaries, be involved in the decision making.
