Multikriterieanalysverktyg vid bedömning av framtida dricksvattenförsörjning / Multi-criteria analysis-tool for assessing future drinking water supply
In this work, a multi-criteria analysis (MCA) method has been developed for evaluation and comparison of alternative drinking water strategies. A selection process of options was proposed and three options for weighting purpose were compared. The work includes an introductory literature study for identification of criteria and indicators (K o I) used during assessment of […]
Varför etableras en forskningsstation vid Bolmen? / Why establish a research station at lake Bolmen?
The article presents the initiative behind the Bolmen Research Station in Hylte Municipality, South Sweden, which was initiated in 2017, enabling site-based research, development and innovation on lakes and lake-based activities starting at Lake Bolmen. This lake is the main raw water resource for Skåne. Since 1987, the company Sydvatten has taken raw water from […]
Recovery of different types of resources from wastewater – a structured review / Återvinning av olika typer av resurser från avloppsvatten – en litteratursammanställning
As the population of the world increases, and economies continue to develop, energy, water, materials of different types, and nutrients for food production will be needed in ever-increasing amounts. The water-energy nexus is well-understood in research circles, but one could modify this paradigm to water-nutrients/materials-energy nexus in order to incorporate recovery of substances that can […]
En flödesanalys för Kävlingeån – HEC-RAS modellering med fokus på dämmens inverkan / An analysis of the Kävlinge River flow situation – HEC-RAS modeling with focus on the effects of weirs
Kävlinge River is one of the largest, and most heavily fish-populated, watercourses in Scania. Eight dams and three active hydroelectric plants are located here, which cause environmental problems; organisms are prevented migration, reproduction and feeding being the biggest issues. Trout and eel, which depend on river accessibility and spawning areas, inhabits the river. This study […]
Wastewater treatment plants as energy-producers: Comparison of the status in India and Sweden / Avloppsreningsverk som energiproducenter: Jämförelse av status i Indien och Sverige
As the population of the world rises and economies grow, both energy and water will be needed in ever-increasing quantities. There is a delicate balance between these two resources called the energy-water (or the water-energy) nexus. One way to reduce the energy consumption associated with wastewater treatment is to use the sludge produced during the […]
This study aims to preliminarily evaluate changes in the risk of cyanobacterial blooms in a eutrophic lake, Lake Vombsjön, in the southern Sweden and test the role of nutrients (phosphorus and nitrogen) in algae formation. Surface water such as lakes service great importance for drinking water supply, such as half of the drinking water in […]
Climate Change and Transboundary Water Management in the Tunisian Mellegue Catchment / Klimatförändring och gränsöverskridande vattenhantering i Mellegue avrinningsområde, Tunisien
Human activities and climate change affect hydrological and sedimentological characteristics within catchments. For arid and semiarid areas this induces direct negative economic and environmental consequences on society. In fact, stability in the rainfall regime and less siltation trapped in reservoirs mean more water for irrigation, water supply, and better flood control. This is especially important […]
Genom att under vintern lagra dricksvatten i den sedimentära berggrunden kan kommuner säkra och transportera en hel årsförbrukning av vatten. Metoden som undersöks i Kristianstad kan vara lösningen på Sveriges vattenbrist under sommaren.
Historiska stormhändelser som underlag vid riskanalys / Studie av översvämningarna 1872 och 1904 längs Skånes syd- och ostkust
On November 13, 1872 an extreme flood occurred in the coastal areas surrounding the South Baltic Sea. An extreme storm surge in combination with high waves caused the death of about 300 people and more than 15,000 people lost their homes. Along the coast of Scania, southern Sweden, at least 23 people were killed and […]
