Methodology for the area assessment in terms of debris flow hazard

Debris flows pose a serious geological risk and therefore it is necessary to take them into account in urban planning by using high-quality engineering-geological data to avoid inappropriate position of construction projects in endangered areas. Wrong position of the Larsi hydroelectric power plant, which is located directly in the historically known extent of debris flows accumulations may serve as an example of such hazard.

The project focuses on eliminating the hazard associated with very frequent catastrophic slope movements of debris flow type causing serious socio-economic damages connected also with loss of human lives in the mountainous regions of Georgia. The project provides new tool FLOW2020 and know-how to the Georgian National Environmental Agency to evaluate endangered areas for urban and infrastructure planning and development in terms of debris flow hazard more effectively. Based on the tool and field validation, a hazard map of model area Kazbegi massif is to be produced with a focus on geological aspects in urban planning and diminishing this type of natural hazards in vulnerable areas.

The project is implemented by the Czech Geological Survey, a Czech company with extensive experience in the field of engineering-geological works.
