Annotation. Rational use of water resources is very important.
Especially in the Republic of Uzbekistan, which pays special attention to the
agricultural sector. This article describes the current state of existing
irrigation networks in the irrigated areas of Bukhara region and the causes of
water wastage and ways to eliminate it in detail.
Keywords:
irrigation, drainage, trough, waste, technical, leakage, evaporation, hydraulic
module, water consumption.
Irrigated areas provide over 90% agricultural products
produced in Uzbekistan. Analysis of the reclamation state of the country's
irrigated lands over a long-term period, discussion of the problems of rational
use, protection and management of water and land resources made it possible to
identify the reasons leading to the degradation of the latter and outline
practical steps to reduce salinity.
Over the past 4 years, great changes have taken place
in our country in all areas thanks to our esteemed President Sh. Mirziyoyev.
December 11,
2020 Resolution PQ-4919 "On measures to accelerate the introduction of
water-saving technologies in agriculture" to some extent serves the
implementation of the tasks set out in other regulations related to this
activity.
The main water
resources of the republic flow from the borders of foreign countries. 180,000 km of irrigation canals serve 4.3
million hectares of irrigated land. It
is known that irrigation networks are divided into permanent and temporary
irrigation networks depending on their function. Water from these networks is divided into 3
types according to the type of waste.
The channel is a waste of water
here:
The
amount of water lost to the bottom of the river (90-95%) is m3 / s
the amount
of water evaporated from the surface to the air (2-4%) m3 / s
the
amount of water lost for technical reasons (2-4%) m3 / s
Significant water losses are due to low efficiency irrigation
techniques (0.6-0.7%) and irrigation systems (0.75-0.86%), poor layout irrigated
areas and over-watering. On irrigation systems with low technical the level of
losses in the network is even more significant.
Water wastage
in irrigation networks is inextricably linked to the length of irrigation
networks. The tendency of irrigated
lands of Bukhara region to become saline leads to the constant supply of
reclamation networks.
Irrigated land in Bukhara region are fully supplied
with water of the Amudarya. The main source of water is II Amubukhara machine
station and Amukarakul canal, additional reservoirs Kuyimazar, Tudakul and
Shurkul. In the spring for flushing the irrigated lands of the region, the
waters of the river are used. Zarafshan. The hydrographic network of the region
is represented by a large number of irrigation facilities and drainage
networks. Main drainage discharges - Central, Northern, Parallel, Tashkuduk,
Parsankul and Ogitma.
Irrigation networks in Bukhara
region at the expense of water management organizations as of November 1, 2020
(total canals)
The total
length of canals in Bukhara region is 1721.1 km, of which the length of canals
is 981.6 km, concrete canals are 728.6 km, gutters are 10.8 km. In percentage terms, most irrigation networks
are groundwater canals. In turn, this
will lead to an increase in waste in the irrigation system.
In conclusion, Aggravated poor technical condition of the conductive network
of canals and drainage systems, irrigation violations and obsolete irrigation
technique, worsens the reclamation the state of a significant part of the
irrigated lands of the Bukhara region.
It is important to increase the efficiency of
irrigation networks in the efficient use of water resources in times of water
scarcity. This is one of the most
important tasks facing the farm, dehkan farm and cluster leaders and all employees
working in the field.
