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”.

Pluviomètre universel OTT Pluvio2

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
