Field Studies of the Dispersed Flow

Abstract

Based on the analysis of previous research, there appears to be insufficient understanding regarding the maintenance of the main water intake structure connecting the Amu Darya River to the Karshi main canal, particularly regarding hydraulic processes leading to erosion and structural damage at connecting points of the channel protection system. Along the water intake segment from Cape Pulizindan on the Amu Darya to the Karshi mainline, there exists a protective structure for the canal banks, functioning not only to shield against adverse water flow effects but also to direct water flow from the river into the canal. To ensure the reliable and efficient operation of supply channel NS-I and the adequate provision of water, a coastal protection structure was constructed within the Amu Darya River bed at an angle of 107 degrees relative to the river's water flow axis. However, this positioning results in water velocity exceeding critical erosion thresholds, leading to deformation of the embankment's protective structure. During high-water months (June and July), the average water flow rate interacting with this structure reaches approximately 1.7 m/s.
