THE NEW APPROACH TO INCREASING OF ECOLOGICAL SAFETY OF THE EXPLOITED EARTH HYDRAULIC ENGINEERING STRUCTURES

Abstract

The state of operated low-pressure hydroengineering complexes with earth dams constructed on small rivers is analyzed. It is shown that many of earth dams have poor condition and are in need of repair work. For increasing of ecological security it is offered to install crest and downstream slope in order to enable passing of rare floods at high-water years directly via an earth dam without the risk of its destruction. The design of earth water retaining structures is proposed. Its advantages are summarized.
