Considerations for Detection of Internal Erosion in Embankment Dams
The paper presents considerations to develop monitoring systems for internal erosion (IE) detection in embankment dams. The need for, and location of, instrumentation systems within a dam must be evaluated by a risk analysis, which develops potential failure modes and detailed information on the concerns leading to those failure modes. Important considerations include: 1) Characteristics of the embankment materials that may be sensitive to IE. 2) Detection of seepage concentrations in sections parallel to the embankment profile. 3) In areas of concentrated seepage flows, detailed information of the ground water characteristics should be obtained using state of the art instrumentation. 4) Proper monitoring procedures for the seepage collected by drain system. 5) Design of data collection systems to obtain continuous readings for long term monitoring. References of where these specialized instruments have been placed and successfully monitored are included.
