Summary |
Studies
are dedicated to determination of wells' systems parameters
under developing set of technical decisions on reclamation
measures optimization to increase land productivity on Central
massive of Hunger steppe. EPP area corresponds to zone of
ephemeral steppes. Relief is slightly undulated. Ground
water table is 1.5-2 m, strongly saline, chloride-sulfate
type. EPP irrigated area is 551.9 ha located in central
part of state farm. Water supply is from canal in concrete
channel and its distributors. On-farm irrigation network
in earthen channel, efficiency 0.6-0.65. 8 operating wells
were constructed. EPP is equipped with water-salt balance
observation and measurement means. According to results
of these studies hydrogeological and technical parameters
of operating wells, filtration parameters of water bearing
layer, drainage module, system operation impact on soil
water-salt regime were determined. System analysis of complex
field studies results as well as water-balance calculations
was carried out. Practical recommendations were given. |

of top and deep horizons level under vertical drainage well
operation" ТИИМСХ papers, issue 59, Tashkent, 1973. Materials of observations
on operating wells group in state farm #17 of Central massive
in Hunger steppe were given. Wells' parameters constructed
in two-layer system, hydrogeological parameters of 'water
bearing layer as well as average annual filtration value
were assessed. |
