The scientific paper is devoted to development the methodology of the rules for control of water reservoirs in the south of the European territory of Russia (ETR), the relevance of that has determined by necessary for more reliable and efficient of river flow regulation. The studies has based on the data of synchronous observations at the region weather stations and of corresponding runoff to the Krasnodar reservoir, it provides rice fields. A correlation analysis between rainfall at weather stations and the corresponding flood volumes have gave possibility to evaluate their rate of dependence. So a predictor weather stations were chosen, which allowed to select decisions in respect to control by water resource of the reservoir. The analysis of traditional and improved rules for control of the reservoir has carried out using a simulation model of its functioning. It has based on the balance formula for water reservoir, taking into account the logical conditions of the traditional dispatch rules for control by reservoir, which designed to compensate for water deficits in rice fields and to be safe during catastrophic floods. The model makes it possible to change the rules of water storage management taking into account short-term forecasts of precipitations and runoff for modeling according to five-day period (pentad) discreteness. The obtained results confirmed the hypothesis about the possibility of reducing the likelihood of emergencies during the catastrophe of catastrophic floods with the stability of the planned water consumption of the irrigation system.

Taking into account modern research methodologies and design of reclamation systems, the experience of the expedition of I.I. Zhilinsky «on the development of the Barabinsk lowland» is considered, which in its organization, efficiency of work, taking into account the natural reclamation features of the reclaimed territory, proved the relevance of adaptive landscape reclamation of the lands of the Barabinsk plain. The Barabinsk plain (Baraba), located in the South-Eastern part of the West Siberian lowland in the interfluve of the Ob and Irtysh, occupies a huge area of 114 thousand km2. In the past, this is a single water area, in the present-a scattering of lakes, swamps and manes. A characteristic feature of Baraba is the General flatness, very weak drainage of the area and its pulsating cyclical aridization and water content. By its nature, Baraba is a unique biosphere territory not only in Russia, but also on a global scale, with a wide range of ecosystems.

Current situation and agricultural management on the non-black earth area of Russia arebeing gradually worsen by the negative natural factors such as a significant increase of weather based climatic abnormal risks, deterioration of agro-meliorative conditions of agricultural lands because of colonization by tree and shrubbery vegetation and secondary bog formation, hidden degradation of soil fertility. When combined with functional loss of ameliorative complex and meliorative systems amortization, regional agriculture adaptation possibilities were rapidly limited. Production shortfall due no abnormal weather conditions for particular field crops was 19…48% during last five years, level of business realization of bioclimatic potential on a field was decreased by 7…12%.The complete realization of regional agricultural adaptive potential to weather based climatic changes and limitation of greenhouse gases emissions is possible on a basis of regeneration ofalll functions and aspects of ameliorative complex management.

In the Kaliningrad region there are about 70 % of all polder lands in Russia. On these lands with high potential fertility, it is advisable to intensive agriculture. The area for the average moisture year is an area with excessive moisture, which indicates the need to maintain the rate of drainage on agricultural land. Many different factors play a role in ensuring the drainage rate, one of which is pumping stations and pumping equipment installed on them. An important parameter in the use of pump-power equipment is energy consumption, since in this industry it is a considerable expense item. Improving the energy efficiency of pumping stations on polders is a pressing issue today. At the majority of polder pumping stations, domestic power pumping equipment is installed with excess power and head of 4–8 meters, and a new one is selected based on the maximum possible head in a given place. In the Kaliningrad region, the energy efficiency of polder pumping equipment has never been analyzed. In this paper, a statistical processing of the geodesic pressure of water at the polder pumping stations of the Slavsk region for 2000–2002 was carried out. On the basis of these data and data on the hydraulic characteristics of pressure pipelines, the calculated water pressures were determined for the rational selection of pumping equipment. The calculation of the economic efficiency of pumps with optimal power compared with pumps of excess capacity. The results of the study can serve as a justification for the transition to the pumping equipment with less power and pressure, which will lead to a decrease in the cost of money for electricity.

The aim of the work is to study the possibility of creating a cortical humus horizon from the surface of a salt marsh from siltysandy fractions of soil with seeds of wild plant species by arranging mechanical obstacles made of wooden material that protrudes 20 cm above the soil surface. The atmospheric processes under conditions of Kizlyar pastures. The research methodology included analyzes, counts and observations of humidity, the least moisture content (HB), enzymatic activity, chemistry and degree of salinity, the study of soil morphology, species composition of phytocenoses and accumulation of their mass on the transformed saline. For 8 years, created on the surface of a salt marsh, the cortical soil layer turns into the Wael eolian-accumulative humus horizon, 5 ± 0.8 cm thick. Solonchak cortical Ccc [AJk – AJ, s – VSA, s – Cca, s] is transformed into a solonchak restricted Scw [Wael – AJ, s – BCA, s – Cca, s]. The degree of soil salinity decreases from a very strong degree in a layer of 0–5 cm to a weak one, in a layer of 6–15 cm to a moderate degree. The yield of phytomass from the saltmaker of the regraded reaches 2.06 t/ha of air-dry mass, which contains 1.85 t/ha of carbon, which leads to an improvement in the ratio of effluents and CO2 emissions, a decrease in the greenhouse effect in nature and an increase in the utilization level of HEADLIGHTS, preventing excessive overheating of the soil and air masses of the atmosphere.

The purpose of the study is to develop a method for calculating flow schedules in the dams ‘ spillway structures, to consider the regularities of the flood flow transformation as a result of exceeding the inflow over the discharge of water into the pond. Given this process in the design of ponds, it is possible to reduce the maximum consumption and, accordingly, reduce the size of the spillway structures and their cost. The object of the study are ponds with small catchment areas, which are characterized by intra-day fluctuations in water flow due to intra-day fluctuations in air temperature and different rates of snow melting during the day. Most of the ponds in the Bryansk region are built on gullies, ravines, streams, very small rivers with small catchment areas, for which it is especially important to improve the methods of calculating the transformation of intraday flood flow and forecasting the shape of hydrographs, the search for the least time-consuming and the most acceptable methods of calculation. The proposed mathematical model allows to optimize the calculations.
