Researchers’ Warning to Significant Reduction of Water in Two important catchments of the country – | Iranian and world news

This Research Under the leadership of Dr. Seyyed Musa Hosseini, Associate Professor of Geography, University of Tehran, climate factors and rivers’ water balance components in the two large catchments of Iran, Karun Greater and Karkheh Basin combined with data. Multiplayer Earth, satellite measurement and ERA5-land network climatic data have been monitored for a long-term 2-year period (1-5).

“The results showed that rain and snow, as two important water sources in both catchments, decreased dramatically during this period and decreased in the Greater Karun basin than the Karkheh Basin,” said Dr. Hosseini. On the other hand, the amount of snow melting in both basins has increased as the air temperature and the temperature of the catchment have increased, resulting in the durability of the snow, which mainly occurs in the Zagros Heights for both catchments. “This change is also more severe in the Karun Basin than the Karkheh Basin.”

The head of the research team explained: “The flow of river discharge at three tight stations (5 % reduced) and Ahvaz (with a 2 % reduction) on the Karun River and the Karkheh Station on the Karkheh River (2 % reduction) has declined in the study interval. “This decrease in river flow rate has a significant relationship with all the parameters under study, but the highest significant relationship was observed between the river flow and snow melting, the temperature was observed for all three waterfall stations.”

He added: “On the other hand, in the short -term period of 5 years, the highest significant relationship was observed between the declining changes of the river flow and the increase in agricultural lands in all three stations, indicating that the factor affects a river discharge at the downstream of both catchments.”

A member of the Department of Natural Geography of the University of Tehran Geography said: “This study showed that combining land data and satellite measurement is an important basis for quantifying the changes in river water bilaterals in response to changes in water-minor agents and can be used in water resources management and the challenges ahead of the two basins.”

Dr. Hosseini added, “This research team is ready to identify the challenges facing water resources in the watershed and effective factors in the country’s water resources challenge and provide solutions to reduce future tensions.”

The results of this study have recently been published by Derringer-Nicher Publications in the form of an article in the International Journal of Environmental Research.
