Efficiency assessment of water resources management and use by simplified indicators

Purpose. Development of simplified indicators for assessment the effectiveness local water flow management and use in reservoirs ponds. Methodology. The methods integral by specific that characterize operational parameters reservoir are used. Analytical formulas calculating applied, their values range from -1.0 to +1.0, which greatly simplifies perception received information. Findings. General characteristic artificial objects study is given. Coefficients regulation surface have been determined. Specific resources established. A formula comparative total risk indicator a conventional distribution scale proposed, according them within administrative units or river basins evaluated elements sample taken study. ratio area territory occupied ponds (44%) (56%) was determined, will retain only 25% volume resources. For almost all studied sample, value average depth less than 2 meters, up 1 × 106 m3. Thereby, most act as evaporation ponds, leads deterioration quality. determined coefficients 9 out 11 regions Steppe Zone Ukraine 0.22 1.36, significant excess permissible norms modular 95% coverage 0.050.25. Kherson (2.14) Odesa (6.45) regions, this parameter exceeds requirements Water Code many times (with norm 0.05 0.2, respectively). Originality. characteristics on proposed point impact bodies surrounding natural environment provided, substantiates emphasizes conclusions regarding irrationality further exploitation such number bodies, particular small Practical value. held simplify information shorten time making protection decisions.
