Thermal leak detection in dams
Flow forces can significantly endanger the stability of earth dams. Flow processes within dams usually change very slowly, often without any externally visible signs. However, the onset of internal erosion can then very quickly lead to a failure of the stability and thus to the destruction of a structure.
Detection of weak points
Weak points in dams and damage to sealing elements can be detected and remedied in good time if they are
e.g. detected as follows:
- Thermal leak detection, also with fully automated alarming.
- Fibre-optic temperature measurements: Gradient method and heat pulse method (HPM)
