Urban infrastructure, such as the water and wastewater system, is at particular risk following climate change. Identifying vulnerable parts of the system contributes to safe and sustainable water and wastewater handling in a long term perspective. The aim of this study was to further develop a GIS-based methodology for mapping physical vulnerability of urban water […]

This paper presents the detection of moisture content in municipal solid waste incineration bottom ash (MSWI BA) with two different measurement techniques. The study used a frequency domain coaxial probe and a short TDR probe to evaluate and compare the performance of the both probes for lossy materials. Instead of using complex data conversion algorithms, […]

Global increases in atmospheric CO2 and temperature are associated with an increase in the temperature of freshwater lakes and marine ecosystems. The ice breakup in lakes occur earlier which gives an opportunity for phytoplankton to grow early in the season. Another effect is a prolonged period of stratification in the lakes. Warming also may cause […]

The main objective of the present study was to apply a numerical modelling system to determine the wave transformation and sediment transport patterns in the Ystad Bay, Skåne, Sweden. This work was performed with emphasis on different time scales and various types of wave conditions. For this purpose, a preliminary study of background data for […]

Results from wastewater treatment plants with their entire biological treatment step in a multi-reactor configured Moving Bed Biofilm Reactor process designed for nitrogen reduction is available on at least five places in Sweden. An evaluation has been made; of the design and reduction efficiency from these five wastewater treatment plants. The study confirms the idea […]

Urban Flooding in Gothenburg – A MIKE21 Study / Urban översvämning i Göteborg – En studie med MIKE21
Climate change has affected the extreme weather throughout the world. Studies have shown an increase of extreme precipitation in Gothenburg, Sweden. A two dimensional (2-D) hydrodynamic simulation model using MIKE 21 was developed as a tool to simulate stormwater related flooding in the central part of Gothenburg. The model was developed using topographical data and […]

Heavily trafficked roads routinely generate a wide spectrum of pollutants, many of these are listed as priority substances according to the EU Water Framework Directive (WFD). Watercourses that intersect with major roads are exposed to both airborne and waterborne traffic generated pollutants, possibly deteriorating the receiving waters. Four bridges within the Segeån catchment area (in […]

When Swedish wastewater treatment plants were rebuilt to include enhanced nitrogen removal, anaerobic ammonium oxidation (anammox) was far from being a mature technology. During the 2000s, the process has been introduced into sludge liquor treatment worldwide. The step to introduce anammox in the mainstream is decreasing, but lab- and pilot-scale studies on real municipal wastewater […]
