De eerste wadi's (water afvoer, drainage en infiltratie van regenwater) en doorlatende verharding zijn al enkele decennia geleden geïmplementeerd in Nederland. Veel gemeenten en waterschappen vragen zich af of deze regenwatervoorzieningen nog goed functioneren na al die jaren en of onderhoud benodigd …

Constructed wetlands are one type of Sustainable Urban Drainage System (SUDS) that have been used for decades in The Netherlands. They provide stormwater conveyance and improve stormwater quality. European regulations for water quality dictate lower and lower concentrations for an array of dissolved …

The results obtained in this study are encouraging and important for the implementation of permeable pavement and swales in The Netherlands, since the performance of SUDS in delta areas and in areas in the world with comparable hydraulic circumstances has been viewed with skepticism. The research undertaken …

In dit afstudeerrapport is gepoogd antwoord te krijgen op de vraag hoe innovaties om bodemdaling in het Groene Hart te reduceren in gang kunnen worden gezet. In het onderzoek is gekeken naar de mogelijkheden die er zijn om innovaties die als doel hebben de bodemdaling in het veenweidegebied te reduceren, …

Verzilting, een te hoog zoutgehalte in het grondwater voor optimaal landgebruik, in gedraineerde percelen met zoute kwel vormt een steeds groter risico door klimaatverandering, bodemdaling en een stijgende zeespiegel. Mede doordat de regenwaterlenzen in deze percelen verdwijnen. Wat de relaties zijn …

Waterpleinen worden op nationale en internationale schaal toegepast om wateroverlast te beperken door regenwater tijdelijk te bergen en langzaam af te voeren. Er zijn slechts enkele waterpleinen in binnen- en buitenland, waardoor de kennis van het (langetermijn-)functioneren nog beperkt is. Dit was reden …

Although permeable pavements have been used all over the world in recent years to infiltrate and treat stormwater, only limited research has been undertaken to investigate and compare the long-term performance of these sustainable urban drainage system devices. This paper presents the results of an extensive …

In recent years, there has been a steady increase in the number of bioretention systems installed worldwide. However, there has only been limited research on the long-term effectiveness of these sustainable urban drainage system devices. This paper presents the results of a series of controlled field …

A baseline study was performed to characterize the stormwater quality from the upstream roofs and road areas. Results showed variations in stormwater quality. This may inhibit single-step treatment performance. Therefore, a ‘treatment train’ of several SUDS measures was developed in order to achieve …

Stormwaters, flowing into storm sewers, are known to significantly increase the annual pollutant loads entering urban receiving waters and this results in significant degradation of the receiving water quality. Knowledge of the characteristics of stormwater pollution enables urban planners to incorporate …
