The significance of intermontane depressions in the Greater Caucasus is rather high for its population, because they include most of high-up populated settlements. Territories of the North-Jurassic depression are the most developed and hold several large communities of mining industry. The number of populated settlements in the areas of the Central depression is rather low, except some touristic centres. This article reviews peculiarities of the hydrometeorological regime of the intermontane depressions. There are two definite groups of depressions in climatic terms such as dry, warm - in the North-Jurassic and Southern depressions and wet, cold - in the Central depression. Four types of depressions have been identified in terms of meteorological type, in particular, cold-humid, cold-dry, warm-humid and warmdry. In general, depressions of the Western part of the Greater Caucasus are fed by rain more than by snow, meanwhile the situation in the Central part is completely different, its depressions are more snow-dependent. Glacier-fed is insignificant for rivers of the North-Jurassic depression, it is spotted only in depressions, which are situated in the Northern part of the Lateral and the Main ridges. Two types of depressions have been identified in terms of hydrological regime: with «local» and with «transit» flow. It is shown that warm-humid depressions with «local» and with «transit» river flow are the most favourable for population’s permanent living and for agricultural activity. It was identified that cold depressions are hardly suitable for organization of permanent settlements. Nevertheless, it is possible to build various recreation and sports facilities considering annual temperature regime and higher thickness of snow in winter. Warm depressions have more favourable conditions for life, however, they have limited water resources and this shall be taken into account when planning their development.
