After graduating as Civil Engineer at TU Delft Floris Boogaard worked at Tauw BV and Deltares at climateadaptation resulting in over 25 years experience in consulting and management. His phd research (TU Delft) deals with the characteristics of stormwater and optimising sustainable urban drainage systems (SUDS) in order to integrate the worlds of spatial planning and water management and encouraging the implementation of innovative technical and sustainable solutions. Floris Boogaard accepted 1 April 2013 a professorship Spatial Transformations at the school of Architecture, Built Environment & Civil Engineering, NoorderRuimte Centre of Applied Research and Innovation on Area Development at Hanze University of Applied Sciences in Groningen. Floris is the co-founder of the company INDYMO (innovative dynamic monitoring systems) that monitors watersystems with innovative techniques as submerged waterdrones or aquabots. His general research and advice fields include stormwater drainage and infiltration, complex monitoring and optimising sewersystems, design of drainage facilities, water supply and groundwater pollution, urban water quality management and urban water management planning. He aims at making sustainable cities in terms of water management.

In this study, different climate adaptation measures and their ecosystem services were categorized into green, blue, and grey categories and weight was given to each category based on their impact on the microclimate. This study took place in the Hillesluis district in the city of Rotterdam and the Paddepoel district in the city of Groningen. In Rotterdam, 21 streets, composed of 42 street segments, were assessed. In Groningen, 17 streets, composed of 45 street segments, were assessed. The available ecosystem services of each street segment were scored from 0–100. The scorecard method that was developed and tested during this study provided insight in the variation of available ecosystem services of streets and street segments. Individual street scores were very low in the city of Rotterdam and ranged between 3 and 50, with the a...

Vaak denken mensen dat wadi's een ideale broedplaats zijn voor muggen, maar dat is niet het geval. Wetenschappers brengen nu met behulp van publiek in kaar waar muggenoverlast en klimaataanpassingen samen vallen - of juist niet

This analysis is a powerful tool in watershed management (Biswas et al., 1999, Yasmin et al., 2013). Climate change coupled with land-use changes raises development issues, including the availability of water resources for people's needs. Faced with these ever-increasing needs of the population, land development becomes a requirement. Thus, the objective is to analyze the morphometric characteristics of the Sankarani basin in order to prioritize its sub-basins. To this end, the satellite images of the digital terrain model (DTM) of the SRTM (30mx30m) type of 2012 were used. Under the Grass GIS open source program, five sub-basins (BV1-I, BV2-M, BV3-Y, BV4-G and BV5-S) have been delimited. The measured parameters are the number of rivers and their classifications, to define the geometry of the basin (area, perimeter, length), the various indices (drainage density, slope ratio, texture ratio, elongation ratio and...

According to the European Bathing Water Directive bathing waters should be closed during cyanobacterial blooms. In the Netherlands, cyanobacteria monitoring in all official bathing water locations is usually performed every two weeks during the bathing season. In face of the large temporal and spatial variability of cyanobacterial bloom dynamics this monitoring frequency however is too low for adequate early warnings to the public. High frequency monitoring and forecasting models can provide information on cyanobacterial blooms in between the regular monitoring dates and for a few days into the future. In the H2020 project EOMORES, we have combined observational data from a spectral camera (Ecowatch) near a Dutch bathing site with fluorescence data from an underwater drone to analyse the variability of cyanobacterial blooms at short temporal and spatial scales. The results are used in a short term forecasting ...

The case studies for a set of common streets in the Netherlands will match urban settings in other countries. The examples show that effective climate-resilient retrofitting is usually quite simple and does not necessarily incur higher costs than traditional approaches, particularly in flat areas. An examination of typical Dutch urban street designs shows how climate resilience can be incorporated under different conditions while keeping costs down with retrofitting. We have investigated the effects of four retrofitting variants and specified their cost and benefits, applying a typology of common residential street characteristics. We sincerely hope these case studies inspire you to get started in your own town, city and country, because the climate is right up your street.

Climatescan is an interactive, web-based map application for international knowledge exchange on ‘blue-green’ projects around the globe. The tool was applied during the Adaptation Futures & The Water Institute of Southern Africa (WISA)conferences, June 2018, in Cape Town. The use of climatescan by different stakeholders during the event led to recommendations for a better application of the web-based map in Africa and around the world.

To reduce the risk of damage, Dutch municipalities will need to retrofit the urban areas in a climate resilient (CR) way. To justify this investment, they need evidence for the possibilities of CR urban street designs and insight into the costs. For characteristic Dutch typologies of urban residential areas we have investigated how to retrofit the urban area. For 10 cases we designed alternatives of street lay-outs and determined the life cycle costs and benefits. This showed that most flat Dutch urban typologies can easily be retrofitted in a CR way without additional costs (compared to the standard designs).

The storm sewers of the city of Almere discharge the stormwater of 1384 ha of impervious area via 700 storm sewer outfalls (SSOs) to the local receiving water system. This water system suffers from eutrophication and long term build-up of pollutant levels in the sediment bed. In order to be able to select the most effective stormwater management strategy, the municipality of Almere and Water Authority Zuiderzeeland have launched a 2 year extensive monitoring project to measure the storm water quality and the potential impact of source control and end of pipe measures to decrease the emission via SSOs. Source control measures, such as removal of illicit connections and increasing the cleaning frequency of gully pots showed to be most effective. The potential impact of end of pipe solutions based on settling showed to be very limited due to the low settleability of solids in the sto...

De drones, uitgerust met diverse sensoren en camera’s, blijken een waardevolle toevoeging aan de reguliere steekmonsters die de ecologische kwaliteit van het waterlichaam beoordelen. Uit de eerste resultaten blijkt dat de drones goed kunnen worden ingezet voor het verkrijgen van een 3D-beeld van de waterkwaliteit en ecologie in de plas, zoals bij de pilot in de Sloterplas in Amsterdam. Na verschillende pilots met diverse waterschappen zullen onderwaterdrones in de toekomst bij watergerelateerde onderzoeksprojecten voor meerdere doeleinden worden gebruikt.
