Study of spatial and temporal variability of indicators of hydrogeological and reclamation conditions, information support monitoring of the hydrogeological and reclamation state based on GIS, forecasting and assessment of hydrogeological conditions of reclaimed and surrounding (monitoring) during the operation of hydroreclamation systems, as well as optimization of information support in the formation of a monitoring system for old irrigated lands.
Implementation based on modern computing tools, with the help of additional software modules and complexes of geoinformation technologies, effective processing of satellite images, geo-modeling and data mining based on fuzzy sets.
Currently, the development of urban areas is fundamentally changing the geological environment and especially its most dynamic component - the underground hydrosphere. In this regard, the problems of studying hydrogeological conditions and, in particular, flooding of built-up areas are becoming more relevant every year.
Most researchers (N.P. Kuranov, A.Zh. Muftakhov, A.P. Shevchik, I.M. Byvaltsev, I.V. Korinchenko, N.M. Grigorieva, V.I. Sologaev, etc.) are under flooding built-up areas understand a complex hydrogeological and engineering-geological process, in which, as a result of a violation of the water regime and the balance of groundwater in the territory, a directed increase in their level occurs, violating the necessary conditions for the construction or operation of individual structures and requiring the use of protective measures [46; 42-p., 69;130-s, 70;272-s].
Automating the creation of digital schemes and cartographic materials (thematic maps with hydrogeological and reclamation characteristics) and in the case of processing satellite images for the corresponding reclamation objects will greatly simplify many problems, first of all, the laboriousness of creating and fragmenting maps with a wide range of scales.
This is necessary, first of all, to create cartograms of hydrogeological and reclamation objects (the question concerns the category of the future development of the GIS "Melioration"). At the same time, with the mapping of layers in the GIS, attribute data is created in the form of tables of thematic content filled with reclamation indicators, which contributes to the best perception and visual assessment of the state of the sites and territories under consideration.
To solve the task, the following stages of work and a sequential process were formulated: development and creation of a series of electronic thematic maps on a single cartographic basis; development of the structure of local monitoring using GIS technologies; in accordance with this, in order to form the structure of the GIS geodatabase, it is necessary to create a subsystem of the reclamation network: a) rivers, sais, canals and ditches; b) reservoirs; c) gateways; d) pipes-regulators; e) crossing facilities; f) pumping stations; g) collector-drainage network; h) vertical drainage wells; i) dams; j) roads; k) any other structures in one or separate topics for each type of structure; l) objects with virtual boundaries in general.
Reclaimed lands: a) conditionally accepted (virtual) areas of the earth's surface: elementary areas, cells, systems, working areas; b) crop rotation fields of agricultural enterprises; c) soil; d) surface topography in several possible representations: height measurement points, contour lines, relief matrix, TIN; e) hydrogeology.
In the process of preparing geodata and introducing GIS technology, the following main tasks of geomonitoring of the reclamation state of irrigated lands were achieved with the implementation of the results in the hydrogeological-reclamation cadastre:
Hydrographic-irrigation network; on-farm (network within the WUA) and inter-farm collector network; network of vertical drainage wells with georeferencing; a network of observation wells for the level of groundwater and mineralization with georeferencing; a network of dynamic points for monitoring soil salinity; irrigated lands with farm boundaries; database of land leaching (materials are formed by SHME jointly with WUAs and districts); other indicators agreed with the Department of Irrigated Land Reclamation.
When solving hydrogeological and land reclamation issues, depending on the changing conditions of each region, it is necessary to take into account the characteristics of irrigated lands for a particular situation, changes in the types of crops and their irrigation rates, irrigation regime and salinity. In addition, irrigation networks, drainage networks, natural drainage networks and their interaction with groundwater, the quantitative values of groundwater inflows and outflows, as well as the design of water intake structures and their actual value withdrawal must be considered.
Approbation of theoretical, technological, methodological and software developments on drinking water supply for reliability and accuracy, creation of mathematical and simulation models for solving hydrogeological and engineering-geological problems in hydrogeological systems based on various applied methods, natural geological and mathematical modeling of geofiltration processes taking into account hydrogeological conditions, in turn, attention should be paid to the formulation and solution of specific problems that take into account technogenic conditions.
Creation of a database for each of the monitored indicators, including; automate the process of creating thematic maps; spread of salinity; occurrence of groundwater levels; state of groundwater mineralization; length and condition of the irrigation network by type; the length and condition of collector networks within and between farms; placement of water intakes of stationary and mobile pumping stations; placement and condition of observation wells (stationary and temporary); placement of salt sampling points along the horizons; sampling points for irrigation and collector waters; the amount of water supplied during irrigation and leaching, spreading areas of leaching of saline lands or water recharge irrigation.
In the future, the use of high-resolution satellite images will provide a large amount of useful information that will provide a detailed quantitative analysis of the distribution of salinity or set the task of why crops have low yields in the study area by the end of the growing season. On satellite images, the collector network is well visualized, its condition: cleaned or overgrown with reed collectors.
