What seismic hazard information the dam engineers need from seismologists and geologists?

For large dam projects a site-specific seismic hazard analysis is usually recommended. These analyses are carried out by seismologists. It is important that the dam engineer, who is the end user of results of seismic hazard analyses, clearly specifies what he needs as the seismologists are not dam engineers and are not familiar with the safety concepts used in dam engineering and the seismic performance criteria for the different dam types

Innovative Solutions for upgrading storage and/or spillage

Most existing or new dams may use one of the 3 solutions presented below and developed for 10 years. Two have been aleady presented in ICOLD Bulletin 144.

Sustainable Development on the Mekong

The Mekong River in Southeast Asia is filled with possibilities when it comes to hydropower development, but a number of concerns can make building new hydro facilities there a tricky and uncertain endeavor.

Ho Chi Minh City Declaration of 2nd Summit of Mekong River Commission

On April 5th, the second Summit of Mekong River Commission (MRC) issued Ho Chi Minh city Declaration on “Water, Energy and Food security in the context of climate change for the Mekong River Basin”. Following is the full text of the declaration.

The Thermal Monitoring Method – A Quality Change in the Monitoring of Seepage and Erosion Processes in Dikes and Earth Dams

The thermal method for monitoring seepage and erosion processes qualitatively changed the monitoring of earth hydraulic structures in the scope of the detection and analysis of seepage and erosion processes. The introduction of Distributed Temperature Sensing and the development of new methods and models for temperature analysis were particularly important

Failure of the Fujinuma Dams during the 2011 Tohoku Earthquake

The Mw 9.0 Tohoku Earthquake resulted in failures of the two dams impounding Fujinuma Ike, in Fukushima Prefecture, Japan. After the event, several mechanisms were postulated regarding the failure modes of the dams

USACE Dam Safety Program Design of Spillway Upgrades

USACE need for passive spillways (such as PK Weirs) to reduce our need forspillway gates

The Piano Key Weirs: 15 years of Research & Development – Prospect

PKW 2013’: 2nd International Workshop on Labyrinth and Piano Key Weirs Paris - Chatou, France 20-22 November 2013

The International Seminar on Piano Key and Labyrinth weirs

I have presented, as member of VNCOLD, the firstkeynote for this seminar which summarized the results of R&D on PKWs, provided some examples of PKW structures and proposedfurther R&D to be carried out in the future to extend the utilization of PKW throughout the world
