Short Abstract
The main goal of the project is to create a comprehensive monitoring system for dikes against inner (piping) and surface erosion as well as deformation. A unique DFO (distributed fiber optical) sensor has been developed to measure total and interstitial pore water pressure in the dikes and underneath riverbeds. The sensor measures filtration and erosion which could lead to dam stability problems.
“It is shown that in many dams which have poor internal erosion and seepage control and are constructed mainly of earthfill, the time for potential development of piping is short, and for these dams continuous monitoring of seepage or surveillance would be needed to detect the piping in time to give warning of possible failure, and to give time to attempt intervention to prevent the failure.”
