Annotation:
On the territory of the Republic of Uzbekistan, internal water
resources are formed in the system of water management, there are several
problems that cause discomfort in the state of Use, and to eliminate these, many
scientific works are being carried out on these, articles are being prepared in
order to solve this problem, and with them changes are being made and
problems are being solved
Keywords:
Channels, filtration, leaks, maintenance
As we know, the movement of jets occurs only in the turbulent mode
movement of the current. As a result of the presence of vertical organizing
speeds, the current carries (transports) sediment (flows) with it on the bottom
and side slopes in the direction of the current. If there are no leaks in the
incoming flow structure, the above situation will be appropriate. If the incoming
flow is high in the amount of leaks, then the opposite happens, that is, the
deposition of leaks. In both of these cases, the formation of the esophagus
occurs. In the first case, there is a deepening and expansion of the oesophagus,
and in the second case, the rise of the slopes of the canal bottom and the sides. In
both of these cases, the ravine continues until its own dimensions correspond to
the speed and flow modes of the current. In other words, the flow rate
transports leaks to a state under the bottom that does not move the material,
and also to a uniform flow depth

B.K.Balakayev in his scientific work summarized his research on the exploitation
of the Karakum canal and scientific research work on the transport possibilities
of the stream. The transport capacity of the stream by it was calculated
according to the following experimental data:

Its values are Y.A.Ibad-zade formula (+7%), I.F.Carasev formula (-7.2%) and
B.K.Balakayev's formulas give satisfactory results when compared with
calculated values (2.3%). It should be mentioned that B.K.To form Balakayev's

where is the break rate determined by the Formula S. YE.Mirshuluva.
B.K.Balakayev goes to two limitations: does not take into account, i.e., the
expression for fine sandy grunts under the conditions of the Karakum Canal;
takes the B values of the fine fractional flows of the Karakum canal as relatively
robust and equal to 0.84.
