Bridges are important components in many transportation networks often spanning rivers and other  water bodies. The failure of a bridge will cause significant direct and indirect economic losses to society.  Scouring of the river bed around bridges is a principal mode of bridge failure typically associated with  large floods. The risk of such scour may […]

We have measured the length of otoliths from cod in 76 pellets regurgitated by cormorants (Phalacrocorax carbo sinensis), collected from the small island Ringburen in the By Fjord which is part of the fjord system between the Orust Island and the mainland. Using a mathematical formula developed in the present paper, we determined the individual […]

Municipal water utilities often only have access to a sparse network of rain gauges (ca. 10 in Stockholm). With sparse networks there is a risk to under- or overestimate sewer flow calculations when showers pass between gauges, or when a spatially concentrated shower hits a gauge. Moreover, significant resources are required to keep the gauge […]

Wave climate data for the Swedish provinces Skane and Halland, were hindcast using SWAN, a third-generation spectral wave model. The 40-year wave dataset, from 1979 to 2019, is made available through an open-access data portal (https://gis.sgi.se/vagmodell/). The wave data has a three-hour resolution and includes significant wave height, peak wave period, and wave direction. The […]

A circular bioeconomy is one in which waste streams from the processing of renewable bio-resources are looped back into the technosphere – open-loop or closed-loop recycling or conversion from matter to energy. This systematic review brings together a small set of 46 publications from the period 2016 – 2021, sourced from 28 journals and originating […]

Missförstånd och ineffektiva arbetssätt hindrar en hållbar och säker dagvattenhantering i Sverige. Det kommer bli svårt att nå målen om en förbättrad vattenmiljö och minskade skador till följd av översvämningar om vi inte börjar uppmärksamma detta och hantera de problem som faktiskt finns. Jag är rädd att vi ser det vi vill se och missar […]

Data compiled by Svenskt Vatten show that in recent years, the levels of diclofenac measured in Swedish lakes, streams and coastlines have exceeded the limits for good ecological status in 18 locations. There is a risk that the limit will be exceeded in an additional 109 Swedish water bodies. Thus, the prevalence of diclofenac is […]
