Flood protection program Zulawy, Gdansk – Poland
Zulawy is a region which is located in the delta of Vistula River in north Poland. The area of Zulawy is about 175 000 ha, almost 26 % of which is situated below the sea level. Because of that Zulawy has an impressive melioration infrastructure – kilometers of channels, hundreds of small dams, lots of pumping stations
In 2010 Polish authorities decided to start the “Complex flood protection program – Zulawy 2030”.
OTT Pluvio²
Pluviomètre selon le principe de pesée
OTT Pluvio2 est un pluviomètre universel à principe de pesée. Il fonctionne selon le principe de pesée et détecte la quantité ainsi que l'intensité des précipitations liquides, solides ou mixtes.
- Intensité des précipitations, cumul, contenu du vase collecteur en temps réel et en temps non réel
- Principe de pesée
- Pluviomètre pour tout type de précipitations, pratiquement pas de maintenance du fait de l'absence de pièces mobiles, satisfait à l'ensemble des exigences de la directive de l'organisation météorologique mondiale WMO N° 8
- SDI-12/RS485, sortie à impulsions
OTT CBS
Capteur bulle à bulle OTT CBS pour la mesure sans dérive du niveau d'eau
OTT CBS est un capteur bulle à bulle compact de mesure de niveau des eaux de surface. Il fonctionne selon un procédé de mesure sans dérive et couvre une plage de mesure allant jusqu‘à 30 m.
- Eau de surface
- Bulle à bulle
- Procédé de mesure indirect sans dérive permettant d'installer le capteur en dehors de l'eau
- 0 à 15 m ou 0 à 30 m
- ± 3 mm (version haute précision) ; ± 5 mm (version standard et 30 m)
- SDI-12 ou RS-485 (protocole SDI-12) ou 4 à 20 mA
Pilot station for “Complex flood protection program Zulawy 2030”, Gdansk – Poland
Complete monitoring solution with OTT LogoSens2, OTT CBS, OTT Pluvio2 and meteorological sensors
Zulawy is a region which is located in the delta of Vistula River in north Poland. The area of Zulawy is about 175 000 ha, almost 26 % of which is situated below the sea level. Because of that Zulawy has an impressive. melioration infrastructure – kilometers of channels, hundreds of small dams, lots of pumping stations
In 2010 Polish authorities decided to start the “Complex flood protection program – Zulawy 2030”. First part of this project should be realized until end of 2015 with a budget of about 45,000,000 EUR. The program has 5 main beneficiaries: RZGW Gdansk, ZMiUW Gdansk, ZZMiUW Elblag, City of Gdansk and City of Elblag. The main tasks for whole program are:
- Modernization of 400 km of river banks
- Construction (or reconstruction) of about 60 pumping stations
- Modernization of about 260 km rivers and streams
- Reconstruction of about 600 km of melioration channels
- Set up a measuring system and an operations center with access to hydrological and meteorological data from the whole Zulawy region
The pilot station is supposed to transfer hydrological and meteorological data to a data centre in hourly intervals. For internal reporting purposes the pumping status (on/off, operating time) should be provided das well. The collected data should be visualized on an internet based platform
The solution consists of:
- OTT LogoSens as heart of the station
- 2 x CBS for water level measurement on both sides of a dam
- OTT Pluvio2 for reliable precipitation data
- Thies WS WD wind sensors
- Vaisala HMP45d as transmitter for temperature and humidity
- Relays inputs to log the status of 3 pumps
- Solar power supply
- GPRS data transmission
- Availability of real-time measurements in the Hydras 3 software
- Dedicated www application
- Steel cabinet with OTT LogoSens2, OTT CBS, OTT Solar and modem
