Sentences with phrase «hydrological changes»
"Hydrological changes" refer to alterations in the movement, distribution, and availability of water in a particular area. It could be changes in the amount of rainfall, water levels in rivers or lakes, or the balance between evaporation and precipitation. These changes can impact the water cycle, ecosystems, and human activities like agriculture or water supply. Full definition
