Ecosystem monitoring of water resources and reclamation facilities

A system of the integrated monitoring of water resources, regular and estuary irrigation lands, and the engineering level of reclamation systems and facilities has been developed for the environmentally safe and cost-effective functioning of the reclamation water-economic complex of the country, based on the example of the Republic of Kalmykia. The methodological basis of the system for monitoring the technical state of reclamation systems and facilities that take into account the regional features of the assessment of classes and design parameters of hydraulic and reclamation facilities are presented. The zonal scale of the soil hydrogeological reclamation assessment of irrigation water quality is proposed; according to this scale, water quality is assessed with respect to the level of danger of total salinization and danger of the development of processes of chloride salinization, sodium and magnesium alkalization, and soda formation in the soil and with respect to the level of alkalinity and the existing hydrogeological conditions in the irrigation site.
