So‘nggi yillarda hujjatlarni raqamlashtirish tendensiyasi paydo bo‘ldi. Dunyoning raqamlashuvi jarayonida qog‘ozga asoslangan hujjatlarni yanada qulayroq, qidirish va saqlash uchun raqamliga aylantirish zarur. Elektron hujjatda (EH) qatorlar matn maydoni to‘plamiga taqsimlanadi. Boshqacha qilib aytganda, satr bir nechta segmentlarga bo‘linib, har bir segment boshqa to‘plam matn maydoniga joylashtirilishi mumkin. Shuning uchun matn satr bilan samarali bog‘langanligi bois to‘plamdagi har bir matn bog‘langan matn maydoni deb ataladi. Shuningdek satrning butun mazmunini o‘z ichiga olgan hamda boshqa matn maydoni bilan bog‘lanmagan matn maydonini himoyalangan matn maydoni deb ham atalishi mumkin.

Technological bases of operation and maintanace of irrigation and drainage systems in water consumers associations
Topicality and demand of the subject of dissertation. The experience of advanced countries (USA, Japan, Spain, France and others.) shows that the most effective authority in the water and land management at the landowners level arc non-governmental, non-profit and community organizations. These organizations contribute to equitable sharing of water resources, regardless of location, type and size of farmlands, prevention of illegal water withdrawals, reduce the volume of irrigation water losses, improving the quality of maintenance of canals, drainage and other infrastructure.
Uzbekistan water consumers association (WCA) is situating in intermediate position between governmental structure of water management and directly main water consumers. WCAs must be equipped with modem water and land resources management methods and tools, for increasing the water using efficiency, as well as coordination of the association members.
"On measures to improve land reclamation and rational use of water resources” from April 19, 2013 and Cabinet Ministries Decree № KM-82 "Approval order of water use and consumption in the Republic of Uzbekistan" from March 19, 2013, contributed in the providing of these studies. These tasks arc designed to mitigate water shortages through the introduction of improved operational adjustment methods of water use plans and optimize areas of crops, improve the efficiency of agronomic and reclamation methods based on the methods of forecasting the dynamics of soil moisture, upgrade laser leveling design methods and technologies.
Subject of research - economic and mathematical model of water allocation and optimization crop areas, soil moisture-storage technology and its models, as well as the technology of laser land leveling with soil subsidence.
Scientific novelty of dissertation research is as follows:
developed water distribution and crop areas optimization method for increasing the irrigation water and land resources productivity;
developed method of forecasting the GWT dynamics with background of SHD;
for the first time developed method for determining evapotranspiration with the development of the plant root system, depth of arable layer and the GWT;
for the first time developed technique for forecasting soil moisture dynamics with background of SHD and applied technologies: traditional technology (root -arable - subsurface layers), stage by stage layer loosening (root - subsurface layers), deep loosening of the field in the vegetation period for the accumulation of moisture in soils (arable - subsurface layers);
developed technology for designing and land leveling works on subsiding soils.
CONCLUSION
Studies allow us to formulate the following conclusions, determined by theoretical and practical significance of the work:
1. An economic -mathematical model (equation 2) to adjust the water use plans in conditions of water scarcity was developed. Optimization problem of water distribution between crops in terms of WCAs and farmers can be solved by proposed model, which will minimize the loss of agricultural production under water scarcity. That allows to increase revenue 342 400 UZS/ha (WCA Sairam Kuyi Suvi -Chirchik district of Tashkent region) compared to the traditional methods of water distribution.
2. The economic -mathematical model (equation 3) for operational optimization of agricultural land with a deficit of irrigation water was developed. Experience of the crop area optimization indicate a need for diversification of species and varieties of crops. Only through proper diversification revenue can increase to the sum of 454 200 Uzb/ha (farm Mamatkul Jurakul ugli at WCA N.Mirzacv Kumkurgan District of Surkhondarya Region).
3. Created the economical-mathematical model (equation 4) to optimize areas of crops and volumes of water allocation under extention of water scarcity. Implementing the optimization of crops area and water distribution in the irrigation water shortage period minimized agriculture losses in dry years. For example, economic efficiency after the introduction of this method in the farm "Saodat" in WCA N.Mirzacv at Kumkurgan District of Surkhandarya Region was 821 500 UZS/ha higher than the control.
4. Until now, when modeling the moisture flow associated with the evaporation of the physical, not considered it’s changing to a limited extent. In this connection, in this work, is taken into account the change of volumetric humidity in the range of wilting moisture to field capacity. Based on the analytical solutions of moisture transfer in automorphic soils in the initial period of plant development and taking into account the development of the root system, by solving the inverse problem in physics (procedure Acad. Abutalieva FB) determined the physical parameters of soil in considered WCA.
5. An analytical dependence (equation 12) determines the moisture flow (physical evaporation) on the earth surface, based on agronomic parameters (tilth), the physical properties of soils and the development of plant root systems and soil humidity changes within a limited range (from wilting to field capacity).
6. The author suggests the analytical dependence (equation 15) of groundwater table dynamics at SHD background in space and time, which differs significantly from the results of P.Y. Polubarinova - Cochina, receiving an average depth of groundwater, the average value of the maximum and minimum water level.
Developed (transcendental) equation (equation 16) to determine the groundwater level to any fixed time period and is a function of the soil porosity, the soil percolation coefficient, the intensity of infiltration, the evaporation at the soil surface, drain spacing and critical depth.
7. The author created mathematical model (equation 17) which describes the SHD resistance coefficient and discharge in time. In contrast to acad. S.F. Averianov receiving SHD percolation resistance and discharge as constant value, the author proves the change SHD percolation resistance and its discharge.
8. Based on this formula the dynamics of the groundwater level, the author developed model (equation 23) and a software for solving the problem on the forecasting humidity for orchards, vineyards and perennial crops, i.e. humidity changes in a homogeneous soil. The results showed that the decrease in volumetric humidity near the drainage is faster than in the middle drainage space.
9. On the basis of theoretical studies, the dependence (equations 26 and 27) the change of humidity in a bilayer soil (vegetation period, arable and subsurface layers) allows to determine the dynamics of moisture in the aeration zone for collecting moisture from "artificial" winter floods caused by the transition to energetically management of transboundary waters.
10. The numerical solution of (equations 29 and 30) equations of the dynamics of moisture transfer in stage by stage layers loosening on the background of the SHD, consider having a two-layer medium (root and subsurface layers). Solution of the problem can optimize the depth and time of stage by stage layers loosening for increasing irrigation interval. The proposed simulation method of moisture transfer stage by stage layers loosening allowed to get accurate data on humidity changes in compared to the previously used method (F.A. Baraev and M. Abbaskhanov).
11. Mathematical models (equations 32, 33, 34), considering three-layer soil (root, arable and subsurface layers) allow to determine the dynamics of soil moisture on irrigated field under SHD background. Using the procedure by solving the inverse problem in physics (procedure Acad. Abutalieva FB) determined the physical parameters of soil in considered WCA.
12. Improved methods of laser leveling design (equations 35, 36) of irrigated land on subsiding soils, reduces the amount of cut/fill works to 12-16% (WCA Muhtarali Yusupov Kurgantepa district of Andijan Region). The developed method promotes creating a stable plane.
