RadClim BSR – En högupplöst nederbördsklimatologibaserad på Radarmätningar för Östersjöregionen
Archived radar data has various applications, though it is often underutilised. Nevertheless, this information has the possibility to aid in the development of accurate and relevant climate adaptation tools, inform climate-resilient urban development strategies, and numerous other personal and societal applications. Our work in the RadClim Baltic Sea Region (BSR) project established the potential features, […]
Regnvattenskörd från tak i urbana områden:kvantitet, kvalitet och miljöfördelar
The hydrological cycle is impacted by ongoing climate changes, which in turn affect the local water supply infrastructure due to increasing demands. With the consequences of globalization, it’s crucial to ensure access to water of sufficient quality. Utilizing rainwater can ease the pressure on local water supply infrastructure, contributing to adaptation to these changes. Flooding […]
Optimerad design av biofilter och svackdiken/dikenför flödesutjämning och rening
Studier av biofilter fokuserar ofta på rening av föroreningar, men deras förmåga att fördröja kraftiga flöden studeras sällan. I den här studien presenteras en optimerad design av biofilter och svackdiken som beräknas ge både bra rening och flödesutjämning även vid kraftiga flöden. I en fallstudie beräknades erforderlig fördröjningsvolym i dessa och jämfördes med densamma för […]
På besök i vattenbristens Los Angeles
I november 2023 fick jag tack vare Xylem-priset chansen att besöka två mycket intressanta vattenanläggningar i Los Angeles-området i Kalifornien i USA: en anläggning i Pico Rivera för återvinning av avloppsvatten, och en anläggning i Torrance för avsaltning av bräckt vatten. Båda dessa anläggningar drivs av the Water Replenishment District of Southern California, som är […]
Walls or the wall, that is the question
A world with multimeter sea level rise is likely to be a world riddled with storm surge barriers. One cannot with certainty tell if or when our world will experience such magnitudes of sea level rise, but we can infer that certain geographical locations offer alternative options to local storm surge barriers. Here, the Baltic […]
Hur blev den kommunala infrastrukturenen offentlig angelägenhet i Sverige? Gator, vatten och sanitet i ett historiskt perspektiv
The first contribution of the book lies in the historical comparison of infrastructural systems that normally are dealt with separately. The synthesis has been achieved mainly by an extensive literature review of research from a wide range of various fields and by using prime sources to some extent. Earlier results have been reinterpreted and research […]
Grönområdens och designregns påverkan påavrinningskoefficienter för dimensionering avdagvattenanläggningar
The effects of green areas on design flow (Qdim) and required flow detention volume (Vd) were studied for different transport times, rain durations and rain intensities. The StormTac Web model was used for the calculations on a 36 ha urban catchment with green areas. Simulated runoff coefficients from different rain intensities and rain durations were […]
Några anmärkningar om jordbruksbevattning med hjälp av avloppsvatten med utgångspunkt från Källby avloppsreningsverk
A historical review of the driving forces behind use of wastewater for irrigation for agriculture in Sweden is presented, starting with a detailed description of the work done at the wastewater treatment plant Käll-by in the city of Lund, south Sweden. Different initiatives have been taken to reduce water shortage in agriculture during the years. […]
PFAS förorening i grundvatten
Aqueuous Film Forming Foam (AFFF) containing Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS) is one of the major sources of groundwater contamination in Sweden. Groundwater contamination caused by the use of AFFF in correlation to fire training events was investigated in Kallinge, Sweden. At the site groundwater was previously used as a drinking water source consequently affecting […]
Vilka klimatfaktorer är viktigast? Del 1
Global warming is leading to more extreme short-duration rainfalls, which need to be considered when designing our society. This is commonly performed by using climate factors, representing the estimated future relative increase in short-duration extremes, to upscale design values based on historical observations. The most recent estimation of climate factors for Sweden was done some […]
