Real-time Bridge Scour Monitoring System by Using Capacitor Sensor
Scour is the erosion of stream bed or bank material from bridge foundations due to flowing of water. Data logging from sensor and electronic communication systems can monitor scour in real-time to ensure the integrity of bridge structure. A number of parameters are associated with scour, thus different types of sensor are required to measure the individual affecting factor. A simple capacitive ...
متن کاملEffect of collar on time development and extent of scour hole around cylindrical bridge piers
An experimental approach was carried out to study the time development and extension of scouring around a circular pier protected by a collar. The experiments included the study of scouring around an unprotected pier as well as the pier protected with collars located at different levels. Width of collars was 3 times the pier diameter. It was found that with collars, though the scour depth and t...
متن کاملBridge Local Scour Monitoring System Using MEMS Sensor Zigbee Network
Wireless MEMS sensors network has been widely used in many fields. In this paper the MEMS pressure sensor is integrated on a sensor board with Zigbee sensor network for real-time local bridge scour depth monitoring during a flood. The wireless MEMS pressure sensor scour monitoring system has been developed and tested in the laboratory. Local scour is one of the major factors for bridge failure....
متن کاملWhite Paper: Tiltmeter-Based Bridge Scour Monitoring
Scour is by far the primary cause of bridge failures in the United States. Scour and other hydraulic effects are particularly threatening because the deterioration is often invisible , hidden beneath turbid water. Many scour monitoring methods attempt to measure the development of scour pockets themselves. However, this is difficult due to debris — both floating and submerged — and shifting str...
متن کاملReal-time acoustic tomography system and the experience of Caspian current sea monitoring
The Acoustic Tomography (AT) systems are used to monitor long-term and continuous flow in rivers, seas and oceans. One of the disadvantages of existing systems in Iran is the inability of real-time/automated measurements. In this study, by adding a raspberry Pi computer to the system and performing the required programming, it was possible to do online monitoring. The data are transferred to th...
