WATER RESOURCES MODELING UNDER CLIMATE CHANGE

Аннотация

Modeling of changes in water resources in the Chirchik river basin in the past, present, and future has been carried out. Changes in river basin flow dynamics showed an increase in the proportion of precipitation frequency change by 2030 (2020–2039), 3050 (2040–2069) and 2070 under two IPCC scenarios (RCP4.5 and RCP8.5). Although there is a tendency to increase water flow in the Chirchik River basin under climate change scenarios, it was found that due to the uneven distribution of water resources in the future, the available water may not be sufficient based on the needs of water users in the basin.
