Problems of small river basins

The analysis of the situation showed that the small rivers of Ukraine are more polluted than the large rivers. This is explained not only by their low water content, but also by the lack of protection. Problems of small rivers lead to degradation of large rivers. Annually, a large amount of salts and a considerable part of the runoff of livestock complexes enter the reservoirs of Ukraine. A considerable amount of mineral fertilizers, poisonous chemicals are washed away and get into the water. There are Zaporizhia, South-Ukrainian, Khmelnyskyi, and Rivne nuclear power plants operating in the Dnieper basin (the country's largest waterway). This adds to the composition of contamination and radioactive. It is known that 370 million m3 of polluted effluents, or 14 % of their volume in the country, fall into the Dnieper annually. In addition, some countries, for example, Cape Town, Cairo, South Africa, Egypt, already face or expect a serious shortage of water supply. Subsequently, Europe may be unprotected from lack of water or water stress. Water stress is a problem that affects millions of people around the world, of which more than 100 million in Europe. Deterioration in the quality of small rivers is a direct threat to human health. There are many integral assessments of the quality of water resources, but the problem is the difficulty in predicting the combined effect of various pollution on humans. The purpose. Preserving the water content of small rivers and protecting them from clogging and siltation. Preservation of water content of small rivers and their protection against clogging and siltation. Conclusions. Given the importance of the existence of small rivers for the proper functioning of all environmental elements and legislative restrictions on activities within small river basins, it is advisable to combine the efforts of authorities and local people to find joint and effective solutions for the management and protection of small rivers, which are a guarantee and indicators of good environmental conditions.
