Projects in Georgia
Natural Hazards along the Georgian Military Road.
Since historic times, the “Georgian Military Road” is the main road connection between Georgia and Russia crossing the Greater Caucasus mountain chain. Snow avalanches and snow drifts can inhibit traffic in winter, enormous mudflows and strong floods may endanger the traffic during summer. The origin of natural hazards, hazard mitigation and hazard management are the main topics of this research subproject.
Types, locations and magnitude of natural hazards will be analyzed by geomorphological mapping and archive studies. The temporal trend of the hazard magnitude and frequency will be compared with trends of climate extremes (e.g. temperature and precipitation trends, extreme snowfall /snowmelt, flashfloods). Land-use change in the post soviet period (e.g. overgrazing, deforestation) may also contribute to an increase of mudflow and flood events. Actual hazard mapping (risk map) and hazard forecasting is intended, based on an interdisciplinary research approach that includes studies in climatology, glaciology, geomorphology, hydrology, landscape ecology, agronomy and socio-economy.
