Summary |
Studies
are dedicated to: assessment of existing design decisions
efficiency and verification of forecast calculations on
drainage work and land reclamation state during the period
of their development. Continuous field investigations included
cycle of observations on water supply, collector-drainage
network operation, ground water regime and salinity, soil
water-salt regime and other indicators of land reclamation
state. Assessment is made for existing design decisions
and forecast methods verification. According to climatic
conditions lands are located in ephemeral steppe. Salinity
type is sulfate-chloride. Lands are salinized and contain
high concentration of gypsum. Field observations were conducted
on two plots (ÓÄÍ-1, area 23.4 ha
and ÓÄÍ-2 with area 25.9 ha) and over all area of state farm during 1976-1979
and 1979-1982. Plots and all territory of farm were equipped
by means of water and salt account and piezometric network.
Obtained experimental information about land reclamation
state dynamics proves accepted design decisions on
rehabilitation measures: due to leaching regime of irrigation
on background of drainage negative salt balance and
soil and ground water desalinization process take place.
Deviation of land development from "optimal" is
explained by organizational reasons. |
