Contribution to the establishment of a monitoring system for storage level, seepage quantities and deformations of the barrage and the surrounding limestone rock.
This publication will specifically discuss the geotechnical aspect of the activities which comprised: Contribution to the establishment of a monitoring system for storage level, seepage quantities and deformations of the barrage and the surrounding limestone rock.
As shown for the example of Gua Bribin, combined investigation, monitoring and numeric models proved to be helpful to understand the seepage phenomena and quantities around underground barrages in karst rock.
They are also commonly used to estimate the quantity of seepage that is expected to pass beneath a levee over time, and to assess the risk of excessively high pore pressures at various points in the foundation.
Researchers are learning how to calculate gas quantities at seepage locations and use these numbers in climate change scenarios.
Prior to that time, petroleum was available only in very small quantities from natural seepage of subsurface oil in various areas throughout the world.
The quantity and distribution of seepage water have now been monitored over 6 consecutive years.
Since there is no established method to directly measure upward seepage in the field, we investigated the possibility of inferring the seepage intensity by using measurable hydrological quantities such as ground and surface-water levels.
Water quantity [i.e. deep seepage (DS)] was evaluated at the catchment scale and resulted from the HILLFLOW model output.
