GLACIAL LAKE OUTBURST FLOOD

"Glacial lake outburst flood" (GLOF) is a term used for a sudden release of water from any type of glacial lake (bedrock, moraine-dammed or ice-dammed), irrespective of its cause. GLOF may results from:

I. dam failure (moraine-dammed or ice-dammed lakes);
II. dam overtopping (all types).

Because of extreme peak discharge and high erosion and transport potential, this type of low frequency, high magnitude flood can easily transform into a debris-flow. Volume of transported material can reach millions of cubic meters. GLOFs and related debris-flows represent significant geomorphic process and also hand in hand significant threat in high mountain areas all over the world. GLOFs claimed thousands of lives and significant material damages. In 21st century these processes require appropriate attention, because it is one of the effects of deglaciation.

This database aims to provide broadly available overview of GLOFs worldwide in standardised format.

Following recent redesigning and updating on the concept of the database management, we are looking for the "regional administrators" - people willing to manage the database for specific regions. For more information please contact Adam Emmer at aemmer@seznam.cz
