Research on the implementation of flooding alert system for he cross-river bridge and the harbor under abnormal climate conditions

  • Date:2019-03-06
  • Update:2019-03-06
  • Department:IOT

Research result:

  Based on the river level and flow rate data obtained from Water Resources Agency and the coastal storm surge and wave data established by Harbor Research Institute, a Cross-river Bridge Alert System will be established to assess the water level near around the cross-river bridge under abnormal climate conditions (Including the composite conditions such as storm surge, long wave and river level soaring caused by typhoon). It will be used to assess the water level near around the cross-river bridge in order to understand the potential effect on the traffic safety when using the cross-river bridge so as to provide reference for the competent highway management unit.

  Implementing the Flooding Potential Map by combining it with Google Earth, for when different levels of storm surges and tsunamis have struck the main commercial harbors.

Troubleshooting:

  • Implement the flooding potential map for the following 8 main commercial harbor areas in Taiwan such as Taichung Port, Budai Port, Anping Port, Kaohsiung Port, Taipei Port, Keelung Port, Hualian Port and Suao Port. In order to solve the insufficient tsunami flooding information problem encountered by these ports, It shall be used by the respective branch office for responding to the hazard when the tsunami alarm occurs.
  • Implement the Cross-River Bridge Alert System for providing the reference on blocking the bridge when stricken by river soaring, storm surge and long wave during the typhoon season.
