History

The Saryozen valley is located in the Semipalatinsk Test Site complex. A total of 24 underground nuclear explosion tests were performed in wells between 1965 and 1980. The area is contaminated.[3][4]

Geography

edit

The Saryozen belongs to the Irtysh basin. It has its sources in parallel rivulets flowing from the southern slopes of the Myrzhyk range and a north-flowing watercourse of Akshok mountain, at the eastern sector of the Kazakh Uplands. The river heads initially eastwards, then it bends northeastwards and in its lower course it bends slightly again and heads roughly northwards. Finally it ends in the Akmolaisor (Shalkarsor), an endorheic salt lake.[5]

The Saryozen flows across a hilly and rugged region of the highland Kazakh steppe. There are many small endorheic lakes along the river course. The river fills in the spring with melted snow and rain, reaching its highest level at the end of April. By the summer it breaks up into disconnected pools.[2]
