For the Water Board of Delfland in the Netherlands , a student search how the drain of rainwater take place in a horticultural company at unlike quantities of water system . Holstein peak from De Lier get together in the project . Mathieu van Holstein : " Water which can not be collect because of constriction in the system is really a release . This project has yielded insights which are very useful in new grammatical construction . "
The Netherlands has a lot of ( built - up ) areas where processing big measure of rain in a short time often causes trouble , such as the Westland , which belongs to the jurisdictional area of the Delfland Water Board . When psychoanalyze the bottlenecks in the quantitative water direction and look for solutions , the water gameboard can not get around greenhouse horticulture .
older policy maker Saskia Jouwersma : " Rainfall is increasing and because of the scale enlargement in horticulture , the connected build - up field are get under one’s skin larger and larger . brainstorm in the manner in which the water is transported over the greenhouse roof and through the drainage system - particularly during heavy rainfall - can help both agriculturist and water handler remove the bottlenecks in water store . water system nuisance is a recurring job and we need each other to deal with this problem . "
With the company layout spread out , Keizer ( left ) , his graduation supervisor Oliver Hoes ( right ) and Van Holstein determine where the various gauges have to be localise ( recognition : Hoogreemraadschap Delfland ) .
Plethora of gaugesTwo class ago , Jouwersma register a research question with TU Delft , to which graduating pupil Kasper Keizer answer positively . genus Gerbera nursery Holstein Flowers from De Lier was fain to alleviate his final project . Mathieu van Holstein : " When possible , we like to cooperate in this kind of initiative . Moreover , water nuisance is quite an issue here in the Oude Lierpolder , so if this research could contribute to improvement , we want to help . "
In March 2019 , Keizer instal a plethora of gauge in strategical seat . The four corners of the roof were fit with rainfall gauge , camera were installed , and a portion of drainage pipe were equip with level gauges . With these gauges , it could be determined whether the content of the drain system was sufficient to also process gravid amount of rainfall without problems .
Van Holstein : " If there are constriction in the system , the drain organ pipe behind it can not drain the water fast enough and fulfill up . If this live too long , the water supply will lam over the gutter border down the facade . Particularly in spring and summertime , we would wish to have this water in the washstand . "
fiddling precipitation , specify resultsAll persona and evaluate equipment give a batch of information , although great rainfall , very utilitarian for the research , stayed away . Saskia Jouwersma : " Our interest is particularly focused on the failure systems in the drainage systems . To bring those in direction , we need heavy rainfall which did not occur during the duration of the project . There has been no overspill from the watershed to the ditch , and the company ’s standing pipes were well suited to their tasks . We have been able , however , to determine that a good deal of precipitation - around 10 percent - is lost due to dehydration from the roof . " Maybe this could be a focal point in the ontogeny of new , advanced greenhouse roof materials or coatings
Mathieu van Holstein : “ The most crucial erudition decimal point for us is to dimension the storage and drain capacity roomily , admit inactiveness of the organization into history . We have always paid attention to this when expanding the company . Now , I would make up even more attending to this , and that is the message I need to give to all agriculturalist : make certain the standing pipes and horizontal pipework do not fill up too speedily and keep a heavy border . Climate change is a given and precipitation will come more and more in the word form of short heavy rain explosion . You have to be properly prepared . "
