Calculation of Bed Load Discharge for Coarse Sand

Myrzakhmetov Akhan, Duskayev Kassym, Tursunova Aisulu, Dostayeva Aigerim

At present, during the period of intensive climatic changes, it is important to thoroughly take into account the hydrological regimes of water bodies. Оnе of the major conditions of ensuring hydrological safety of territories is а reliable forecast of stream-channel deformations and channel-related processes in the case of water bodies and their separate sections. This paper reviews different methods of calculating bed load discharge. Thus, a new technique оf calculation оf bed load discharge was developed with consideration of the probabilistic estimate оf the beginning оf bed load motion. The method shows satisfactory results compared to previous techniques in use.

Features of the Sediment Runoff Regime Downstream the Ile River

Duskayev Kassym, Myrzakhmetov Akhan, Zhanabayeva Zhanar, Klein Igor

Journal of Ecological Engineering

2020

Vol. 21, nr 2

117--125

This paper is devoted to study on the sediment runoff of the Ile River downstream. The article analyses the Kapshagai reservoir impact on the regime and characteristics of the sediment runoff in the Ile River downstream before and after construction of the reservoir in 1970. Along with the calculation of characteristics of sediment runoff, an assessment of the amount of the suspended sediment, which is in the bowl of the reservoir, was shown. Furthermore, the impact reservoir on the granulometric composition of the suspended and bed sediment of Ile River was calculated.
