Om vattnets förunderliga kraft / On the fascinating waterpower
The history reflected in water may reveal both fundamental and sometimes astonishing insights. In this short essay we meet two Swedish very experienced engineers, both also representing a humanistic profile. The first one to meet is the late professor Bo Hellstrom, at the Royal Institute of Technology. As a young engineer he was intrigued by […]
Investigating the state of rural water supply in rio grande do sul, brazil / Om tillståndet för landsbygdens vattenförsörjning i rio grande do sul, brasilien
In Rio Grande do Sul (RS) in Brazil, more than one million residents rely on small-scale water supply solutions without conventional treatment. This study aimed to investigate water services in rural areas of RS through case studies and interviews with authorities, researchers and support organizations within RS. Microbiological contamination is widespread, while non-compliant fluoride levels […]
En undersökning av skelettjordskonstruktioner med hydraulisk modellering i MIKE URBAN+ / An investigation of structural soils using hydraulic modeling in MIKE URBAN+
Urbanization with growing and denser cities in combination with climate change requires a smart land use with multifunctional facilities. One such example is structural soils that have a bearing capacity to handle loads, create favorable conditions for trees and handle stormwater with purification and delay. In this study, interviews with municipal employees have been conducted […]
Projekthandboken VA
The investment rate in Sweden’s public water and wastewater systems have increased in recent years due to an increased need for renewal and replacements of older systems, as well as for new investments in pipe systems, pumping stations, water works, and water treatment plants. In 2017 about 12 billion SEK was invested in the public […]
Forecasting combined sewer flow using x-band radar with a neural network – a case study in Lund
This study aimed to forecast combined sewer flow into a wastewater treatment plant in Lund, Sweden by using uncalibrated X-band radar data with a neural network. Neural networks have proved themselves useful in the field of forecasting as they can solve multiple kinds of problems and recognise patterns in the data as well as model […]
Solving incidents with contaminated drinking water using hydraulic modelling
During 2017, two incidents with coliform bacteria in the drinking water occurred in Lund, South Sweden. Boil water advisories were issued and the extensive work began to limit the affected areas, find the sources of contamination and restore the network to normal conditions. During both incidents, hydraulic modelling was used as part of the trace […]
Den marina miljöförvaltningens utveckling i Sverige från 1960-talet tills idag
Most coastal countries lack a coherent marine policy or set of coherent policies covering various marine policy areas. These include, for example, fishery, aquaculture, mineral extraction, transport, military de- fense, environmental protection and conservation, pipelines, energy production, coastal development, tourism, other marine activities and overall, the climate. Often there is an inability to see and […]
