The hydrological foundations of landscape planning of the Lake Sevan basin

The main stages of elaborating the landscape master plan for the Lake Sevan basin with reference to the water component are highlighted. Scientific basis for investigating the hydrological organization of the territory is provided by the landscape-hydrological approach determining the interrelationship of quantitative-qualitative characteristics of the runoff with landscape elements. The focus is on the selection of criteria and on the theoretical substantiation of the factors of assessment of the water potential; a number of recommendations for targeted utilization and improvement of the water-ecological situation of the territory are made.
