摘要：Extreme weather events are likely to increase in the future, and thus damage to the environmentand infrastructure will likely increase during this time, too. To adapt to these weatherimpacts, forecasting, now-casting, and in situ monitoring installations have increased duringthe last years. Even though monitoring stations deliver frequent measurements in realtime,a dynamic implementation of measurement frequencies, adapted to certain environmentalconditions, are rarely implemented. Within this paper we provide a frameworkwhere low frequency phosphorus measurements in the Mondsee catchment can be adaptedto high frequency measurements during storm events. When heavy rainfall is observed, athreshold event triggers a reconfiguration task for the phosphorus measurement device,using asynchronous, push-based communication. A Sensor Planning Service commits sucha request into the wireless sensor network, and updates the measurement frequency of thetarget nodes to enable nutrient peak flow estimation during storm events. This setup introducesthe possibility of measurements in flooded areas without using traditional (manual)sampling methods, and we expect to obtain a better understanding of discharge to phosphorusrunoff relations.
