Assessing seepage flow conditions through a dam quickly and accurately without drilling or drawing down the reservoir
This paper examines the application of a proven geophysical technology that is highly effective in assessing seepage flow conditions through, beneath and around earthen embankments. The technology works rapidly with minimal disruptions to dam operations—it requires no drilling or draining of the reservoir. It has become a competitive solution to many of the complex challenges faced with dam ...

Dam safety inspections
This dam safety inspection was carried out to monitor the safety of a stone masonry overflow dam (12m high and 161m long). The geological makeup of the region comprises Ordovician period limestone and loose Quaternary sediments. One set of data was collected by placing 64 electrodes along the dam with 3m spacing. The inversion image below shows the areas aligning with 0+107m to 0+112m and ...

Höljes Sweden Project - Case Study
In 2013-2015 extensive work was made to increase the dam safety in Höljes. Improved monitoring was required to bring it up to today’s standards but due to the condition of the dam foundations and high downstream water level, installation of a traditional leak detection system was not possible. HydroResearch proposed that high accuracy temperature measurements be made ...
