Vattenförsörjning i Serbien – intryck från ett studiebesök
During the spring of 2019, I had the opportunity to visit two waterworks in northern Serbia, in Subotica and in Novi Sad. In the latter city, I was also given the opportunity to meet researchers at the University. Serbia is one of the Balkan countries affected by high levels of naturally occurring arsenic, which in […]
Skyfall – från en reaktiv till en proaktiv planeringsprocess
Our cities are extremely vulnerable against heavy rainfalls. This was clearly shown by the cloudbursts that occurred in Copenhagen 2011 and in Malmö 2014. These events was a wakeup call for many. In the present study, an interview study was conducted to highlight how flooding during cloudburst is currently handled in Sweden and neighboring countries. […]
Flödesmodellering i MIKE urban baserad på högupplöst X-bandradardata
In recent years, X-band radar has emerged as a tool to improve the input data to rainfall-runoff modelling in urban catchments thanks to its high spatial and temporal resolution compared to other radars used for precipitation measurements. An X-band radar was installed in a pilot project run by VA SYD and LTH, ten kilometres east […]
Impact of sand fences on dune evolution at Vejbystrand
Ängelholm’s coast has eroded considerably in the past decade in part due to a period of frequent storms. As climate continues to change, parameters that increase erosion such as sea level rise and storm frequency will become exacerbated. Adaptation measures must be put into place in order to mitigate the impacts of coastal erosion. This […]
Extreme value analysis of wave runup and dune erosion at Ängelholm beach, south Sweden / Extremvärdesanalys av våguppspolning och dynerosion vid Ängelholms strand
This study employs extreme value analysis to estimate 10-, 50-, and 100-year return levels of wave runup and annual dune erosion on the basis of 40 years simulated data from Angelholm Beach, Sweden. The offshore wave climate is computed with the SMB-formulations and propagated nearshore with the SWAN wave model. The runup is computed with […]
Vattnets roll i Tchads jordbruksproduktion – metoder för förbättrad analys av jordbruksförändring / The role of water in crop production in Chad – methods for improved analysis of agricultural change
Agriculture constitutes the largest economic sector and professional occupation in Chad, and is undergoing rapid changes due to processes of population increase, institutional reforms, conflicts in neighbouring countries, increasingly globalized trade networks, and environmental changes. But despite their importance for livelihoods and economic growth, the specific patterns and drivers of change in the agricultural sector […]
Utvärdering av filtermaterial för att avlägsna lösta organiska föroreningar i dagvatten / Evaluation of filter materials for the removal of organic contaminants in stormwater
Stormwater is frequently contaminated with organic pollutants such as polycyclic aromatic hydrocarbons (PAHs), phthalates and alkylphenols emitted from traffic and building materials. Filters with adsorbing materials have the potential to remove dissolved, colloidal and particulate organic pollutants from stormwater. The aim of this research project is to investigate how effectively filter materials remove dissolved organic […]
Chemical rehabilitation of rapid sand filter at Klagshamn WWTP in Malmö / Kemisk rekonditionering av sandfilter på Klagshamn ARV i Malmö
At many wastewater treatment plants (WWTPs), rapid sand filters are used as polishing step before the wastewater is released to the recipient. Thus, after time, the media gets clogged and the filters are regularly backwashed. In case of poor backwashing, the next filtration cycle will begin with an inefficient filter. Agglomerates of media grains, flocculation […]
