Water Balance and Physical and Chemical Properties of Water in Lakes of Kazakhstan

Abstract

According to the conditions of water exchange, there are differentiated drainage, periodically sewage, sewage, and flowing lakes in the territory of Kazakhstan. Main of them are drainless. The components of the water balance of the drainless lakes (surface runoff, precipitation falling on the surface of the lake, groundwater, filtration, and evaporation) are subject to large intra-annual and long-term changes. They are in conditions of shallow water lead to a characteristic for Kazakhstan in inconstancy level, the drying out of a significant part of the water bodies in summer and autumn seasons, as well as in perennial low-water periods.
