THE RELATIONSHIP BETWEEN THE CHARACTERISTICS OF GROUNDWATER AND SURFACE WATER IN THE KASHKADARYA REGION

Abstract

Understanding the interplay between groundwater and surface water systems is crucial for effective water resource management and the preservation of aquatic ecosystems. River water chemistry and temperature are profoundly influenced by groundwater discharge, particularly in arid and semi-arid regions like the Kashkadarya River Basin [1-3]. Groundwater typically provides a relatively stable source of water that can buffer against extreme temperature fluctuations and dilute the effects of surface runoff. This study aims to investigate the spatial and temporal dynamics of groundwater-surface water interactions within the Kashkadarya River Basin, focusing on their impact on river water chemistry and temperature [4-7]. We hypothesize that groundwater input will be characterized by relatively stable temperature and higher concentrations of dissolved solids compared to surface water, resulting in observable changes in these parameters along the river course, particularly downstream in the Karshi Steppe region.
