A parsimonious lumped model was developed for simulating a catchment composed of a landfill and recycling facility. The modelling results showed acceptable conformity with the observed values with NSE of 0.54 and R2 of 0.56 in hourly simulations, though the results were characterized by a general underestimation. The catchment model was coupled with a reservoir […]

Climate change is expected to increase the frequency of fluvial, pluvial, and coastal flooding which must be considered in spatial planning. More frequent floods will also affect financial stability by increasing the exposure of risk for insurance companies and creditors. This study investigates how selected stakeholders assess flood risk when planning for new development and […]

Unintentional or planned operations of valves and pumps create pressure waves, called transients, which travel through pipe systems with the risk of, among other things, breakage and fatigue. Knowledge about transients in pipes and associated effects are not new. The problems with transients in Sweden were elucidated in a report published in the 1980s, where […]

Municipal water and wastewater pipe projects are often complex in terms of quality assessment, work environment, technology, time frames, personnel resources, and budget frames. If the water and wastewater pipes laid today are to maintain the service life that the Swedish Water and Wastewater Association (Svenskt Vatten) sets as a goal, 100 – 150 years, […]
