The decline in water level of Lake Urmia is one of the regional environmental crises. One of the measures to rehabilitate Lake Urmia is the inter-basin water transfer from the Zab Basin to Lake Urmia through the Kani-Sib tunnel. The aim of the present study is the hydraulic and hydrological investigation of the water transfer project from Kani-Sib Dam to Lake Urmia. https://danddcollectiblers.shop/product-category/sweets-jar/
