Abstract

Aim: The aim of this paper is to determine quantity of the water resources according to the landscapes in Georgia, using multifactorial analysis.

Methodology: Assessment of water resources (hydro resources) potential of landscapes requires multifactorial analysis.? Their potential is determined by quantity of influent and effluent waters during certain time periods. This study was mainly based on multiyear hydrological data of Georgia covering 90 rivers. Series of observations included a time scale of 40-50-years and in some cases even 70-years. Study was based on cadastral data of 150 hydrological stations/posts.??

Results: We investigated different and similar landscapes according to total supply of water resources. The landscapes situated under more or less uniform physico-geographical conditions are similar in their total supply of water resources. Landscapes within the limits of one type or even subtype differ according to the supply of water resources, particularly water resources supply is maximal under these conditions.

Interpretation: Accuracy of our results has been testified by the circumstances. We got approximately the same total values for whole Georgia as determined by the calculations made by different scientists using different methods.
