METHOD FOR DETERMINING THE CHANGE OF TOTAL PERENNIAL WATER RESOURCES IN THE SOILS OF THE RIVER POOLS

摘要

A method for determining the change in the total moisture reserves in the soil of river basins by measuring annual precipitation and river runoff, characterized in that, in order to enable the determination of the long-term average values of the change in the total moisture reserves, the air temperature and the elasticity of water vapor at the height of the meteorological booth are additionally measured, and the desired value changes in moisture reserves are found by the formula: where ΔU is the change in moisture reserves in soils, mm; - precipitation, mm; Q - water consumption, mm; e is the vapor pressure, mbar; T - surface air temperature, ° C.
