FIELD: construction.
SUBSTANCE: invention relates to hydraulic power engineering, namely to methods of using water resources of plain rivers, and may be used in construction of small hydraulic power plants. The method includes construction of a drainage channel 3 on a sloping coast 2 along a dam 11, and this channel is coupled in a lower reach with a river 1. On a steep coast 7 in areas of undesirable floods of territories they build protective dams 10 and systems of drains and sewages 8, which are connected to the drainage channel 3 of the sloping coast 2 by means of pipelines 6, laid along the bottom of the river 1, thus completing preparation for construction of the solid dam 11 for narrowing of the river bed 1. They build a dam 14 and complete construction of the dam 11, coupling in the lower reach with the dam 14. After that they complete construction of the dam 14 and the building of the hydraulic power plant.
EFFECT: invention makes it possible to reduce areas of alienated territories, which reduces environmental disturbances in a river basin, and also provides for generation of hydraulic energy at large rivers with usage of their channels or specially erected channels at minimum damage for territories adjacent to the river and accelerated time of erection of plain hydraulic power plants.
