Development of cost-effective ground-based and remote monitoring and early warning system for detecting debris flow/landslide initiation

Project background

Each year landslides, debris-flows (mud-flows, earth-flows) cause a lot of disasters in mountainous areas all over the world. Periodically thousands of populated areas, dams, roads, oil and natural gas pipeline routes, high voltage electric lines and agricultural lands are under the heavy influence, sometimes with catastrophic impact of hazardous geological processes. Catastrophic mass-movements not only periodically strongly damage the environment, but they also are followed by human losses. Thus it is of great importance to create reliable and cost-effective early warning systems for monitoring mass-movements in potentially dangerous areas. There are a lot of methods in monitoring mass-movements, but the cost of such systems is very high and it is practically impossible for developing countries to purchase them. Besides, the number of mass-movement dangerous sources is huge. Thus, the multitude of dangerous sources, growing number of exposed vulnerable objects and limited resources of developing countries, which are most prone to mentioned hazards call for developing cost-effective and the same time accurate monitoring /early warning telemetric systems. A fusion of these apparently conflicting concepts (cost-effectiveness and accuracy) is possible using the modern high-tech systems.

Project implementation

European Centre on Geodynamical Hazards of High Dams - Georgia :

This project aims to develop a cost-effective complex telemetric geophysical monitoring and with autonomous power source (solar batteries) for signalling debris flow/landslide initiation using radio signals or Internet connection.

The complex includes monitoring of two main categories of parameters leading to mass-movements: soil humidity and deformation (e.g. displacement/acceleration/micro-seismicity) caused by the hydro-mechanical loading of the slope. Two types of approaches will be pursued: the development and test of 1) ground-based modern sensors, and of 2) remote sensors (such as terrestrial cameras and very-high resolution satellite imagery).
