Modeling energy losses in the hydraulic system of Vombverket water treatment plant / Modellering av energiförluster i Vombverkets hydrauliska system
Vombverket, one of the major water treatment plants in south Sweden, originally built in the 1950’s, was significantly expanded in the 1990’s. Because of this expansion, the water flow path was prolonged. The plant was not optimized for the new process design with regard to the hydraulic conditions, but substantial pressure losses were introduced through […]
Sexton år senare, kommentarer till debattartikel Vatten – demokrati och inflytande med ett nytt EG-direktiv (Vatten 56:51-55) / Sixteen year later, comments on the article Water – democracy and influence with a new EC-directive
Med anledning av arbetet med EUs vattendirektiv skrev jag 2000 en debattartikel med titeln »Vatten – demokrati och inflytande med ett nytt EG-direktiv» (Karlsson 2000). Eftersom vattendirektivet hade en tidplan med flera delmål kändes det då frestande att beskriva ett framtidsscenario. Artikeln andas enorm optimism och entusiasm – svår att förstå så här i efterhand.

Klimatanpassning mot urbana översvämningar genom transprofessionell samverkan / Adapting to flood risk in a changing climate through transprofessional cooperation
Due to climate change, more extreme precipitation is expected to strike cities around the world. Urbanization along with densification of urban areas magnifies the impact of heavy rainfall. More robust and flexible storm water systems that mimic processes of the hydrological cycle are needed to make urban environments more flood resilient. Such systems must be […]
UV/VIS spectroscopy as a method to characterize well water quality / UV/VIS-spektroskopi som metod att karakterisera brunnsvattenkvalité
The applicability of UV/VIS spectroscopy for the characterization of well water quality was studied by analyzing 219 private wells from sparsely populated areas of Finland. In addition to conventional water quality indicators, such as conductivity, nitrate and DOC, a series of UV/VIS spectroscopic parameters were determined: A-224, A-254, A-280, A-365, A-436, the area under 250–350 […]
Kostnads- nyttoanalys av införandet av hållbar dagvattenhantering som riskreducerande åtgärd mot översvämning – med fokus på monetär värdering av ekosystemtjänster / Cost-benefit analysis of sustainable drainage system as flood risk reduction measure in urban areas – Focusing on monetary valuation of ecosystem services
In this study a cost-benefit analysis (CBA) of a sustainable drainage system (SuDS) as a risk reduction measure is performed. The case is applied on the flood prone area Söderkulla in Malmö, where the focus of the study is quantification and valuation of the expected increase in ecosystem services as a result of the SuDS. […]
Statistical analysis of extreme sea water levels at the Falsterbo Peninsula, South Sweden / Statistisk analys av extrema vattenstånd vid Falsterbohalvön
Falsterbo Peninsula on the south coast of Sweden is low-lying and exposed to flooding. In 1872 the extreme storm surge Backafloden caused large devastation on the Swedish, Danish, and German coasts in the South Baltic Sea. For the Falsterbo Peninsula, the peak storm surge level is estimated to have been 240 cm above normal. If […]
Changing wind properties in south Sweden since the days of Tycho Brahe / Ändrade vindförhållande i södra Sverige sedan Tycho Brahes dagar
The famous Danish astronomer Tycho Brahe initiated meteorological observations on the Island of Ven that were recorded in a diary, starting in October 1582 and lasting almost uninterruptedly until April 1597. Although the observations were mainly qualitative due to the lack of proper instruments and procedures in those days, a lot of useful information can […]
Coastal erosion and beach nourishment in Scania as issues in Swedish coastal policy / Skånes kusterosion och strandfodringars roll i svensk kustpolicy
This paper discusses the dynamics of coastal policy change in Sweden, using erosion and beach nourishments as an example. The Multiple Stream Model is a theoretical model on agenda setting and policy change developed by the political scientist John Kingdon (1984, 2003). This paper applies Kingdon’s model in describing and explaining coastal policy dynamics regarding […]
