Föreningen Vatten 70 år – några reflektioner med anledning av dess födelsedag / The Swedish Society for Water celebrates its 70th anniversary – a few reflections
The Swedish Society for Water celebrates its 70th anniversary 2014 and can thus look back on a comprehensive water deed during the years. In the journal Vatten (Water), that took ahead as Water hygiene in the year 1945, a large number of papers, abstracts and notes have been published, which describes this yield. In my […]
ERT och TEM som verktyg för grundvattenundersökningar – jämförande studie i Skåne / ERT and TEM as a tool for groundwater investigations – Comparative study in Skåne, southern Sweden
The study presented in this article addresses geophysical methods that can create 2D and 3D models that reflect the geology. The models can be used as a tool for mapping of groundwater resources. Four profiles, located in Vombsänkan in southeastern Skåne, have been investigated with Electrical Resistivity Tomography (ERT) and Transient Electromagnetic Soundings (TEM). The […]
Testing different rehabilitation options in the drinking water pipeline network in Oslo using DYNAMIC METABOLISM MODEL (DMM) / Utprøving av forskellige rehabiliteringsopsjoner i Oslos drikkevannledningsnettverket ved bruk av den dynamisk-metabolism-modellen (DMM)
This study is being carried out at the behest of Oslo VAV (Vann og Avløpsetaten; Water and Sanitation Utility) personnel, as an additional test with the Dynamic Metabolism Model (DMM) developed at NTNU in Trondheim. It considers rehabilitation of drinking water pipelines as the only intervention in the entire system; and tests for different rehabilitation […]
Planering för ett förändrat klimat – strategi för att hantera stigande havsnivåer i fysisk planering i Ystad, Skåne / Planning for climate change – a strategy to manage sea level rise in spatial planning in Ystad, Scania
Ystad municipality in the south of Sweden is working on an extension of the comprehensive plan for the main city and its surroundings. Ystad is situated on the coast and the effects of climate change are expected to be challenging in the future. Sea level rise will increase the risk of flooding and erosion in […]
Sediment transport and coastal evolution at Thuan An Inlet, Vietnam / Sedimenttransport och kustutveckling vid Thuan An-inloppet, Vietnam
The Tam Giang-Cau Hai lagoon in Vietnam has two inlets and outside one of them, the Thuan An inlet, a groin was constructed in 2008 to reduce sediment transport and prevent the inlet from closing. This groin has caused erosion and accretion of sediment on the adjacent coastline. The objectives of this study were to […]
Storm-water management in Malmö and Copenhagen with regard to climate change scenarios / Dagvattenhantering i Malmö och Köpenhamn med avseende på klimatförändringsscenario
The current status of storm-water management in the neighbor cities of Copenhagen and Malmö was studied with respect to present measures and the implemented systems in both cities. Application of blue-green solutions in the outer parts of Malmö started in the 1990s; hence collaboration between different departments in the municipality is more structured in the […]
Spatial variability of soil water content and salinity in a semi-arid agricultural field / Rumslig variabilitet av markvattenhalt och salinitet i ett semiaritt fält
One technique for collecting rainwater and prevent soil erosion applied on large areas in Tunisia involves the use of soil ridges (1-1.5 m high). These contour ridges are constructed parallel to topographical isolines. The effects of the contour ridges on the soil water content distribution, bulk soil salinity ECa, and soil water salinity (ECw) were […]
Suggestions for Designing and Constructing Bioretention Cells for a Nordic Climate / Forslag til dimensjonering og utforming av regnbed for nordiske forhold
Bioretention cells (also referred to as raingardens or biofilters) are constructed as shallow vegetated depressions and are generally considered a flexible practice for local stormwater management. Runoff is retained at the cell surface before it percolates to the ground or is conveyed to the stormwater system. Flood risk is reduced via retention and volume reduction […]
