Rijnland: allegedly hesitant, especially about integration beyond communication (don't see“what's in it for them”).Meeting with René van der Zwan:Currently, they are using their second version of a DSS.One pumping station completely automated, others in progress - 2015 date for fullautomationDSS is controlled either:remote control (manual)preprogramming (in advance) - 10 actions, useful for more than 24h in advanceautomatic: DSS advice is automatically acceptedWatermanager can work from everywhere (intranet,internet,mobile) - VPN securityCollection points on polders currently around 100 - predicting to increase to around 1000 inthe future (collection every 15 mins)Water levels (22 stations), Rainfall data (6), Salinity (17), Discharge (10) Water levels fromRWS (12 stations)Weather data collected from Meteo Consult and KNMI (2 stations) - reliable only up to 24hWind information is integrated into their DSS programming.All data goes into an hydrological database to be used in future models.*They take into account tidal movement near Gouda, but not in the NZK. The argumentpresented is that the margins are not sufficient to take relevant benefits from it, which mighthave been disproved by discussion with Peter-Jules.*All this information can be acquired at any point by asking Mr van der Zwan as he preparedan excellent presentation for us and would not doubt be able to share the latest status atany point.Current and desired collaboration:Information exchange with neighbouring waterboards AGV and HDSR as they use the samesystem, so real-time numbers on current flow, waterlevels, ... are shared into a commonserver and refreshed several times per hour. There are plans to also include predictionssoon.Their predictions of discharge information in the NZK are sent to RWS (but not used) andthey expressed interest in being able to receive RWS's predictions back as well.While attempting more complex types of collaboration, they have to go around thewaterakkords and european regulations to be able to coordinate with other waterboards.The benefits they expect to have when enhancing their systems are: increase of peakcapacity storage basin (1/100 year failure) and improvement of water quality control(salinity).Their interest in saving energy is limited but have some initiatives on that front as well:- watertreatment (RWZIs) by exploring alternative energy sources- pumping energy at night (off-peak)v- Wind energy- more flexible water levels27
Hoogheemraadschap De Stichtse Rijnlanden (HDSR), which does not border the NSC butdoes border the Amsterdam-Rijnkanaal (ARK). That way, there is an indirect connectionbetween them and the pumping station in IJmuiden, as the ARK and the NSC are an opensystem.Meeting with Edwin JongmanAll stations function on an automated basis, sending warnings to watermanagers in case offlood possibilities. Claims also that this is not very usual in RWS systems.Their predictive model is not good enough to make long term predictions yet, so they justuse the model to react on current conditions. The intention is to start applying predictionssometime in the near future.Points out that for building a proper predictive model they would like to have more historicaldata like weather predictions that is not available publically, so have been investing inbuilding up a 5 year Hydrological database that is available at any time.Enjoy a good relationship with RWS-Utrecht, as communication by phone (cellphone tocellphone) is allowed and welcome, for all kinds of situations.Would like to have better margins on dry summers with cooperation from RWS-NH, butrealize RWS has to worry about a lot more factors, so understand cooperation is slow.The problem in this case stems from the fact that the DSS aims for a medium level, whichvaries due to predicted variations (which only go so far). The idea would be to vary this "setpoint" also according to the seasons.This waterboard, out of the 4, seems to be the one that lacks the most incentive to invest inimproving their systems, as their gains would be much less significant and right now thesystem does its job.”28
