Experience in environmental substantiation of water management measures using the example of deepening and straightening the river bed of the Alei

The article summarizes the experience of pre-project environmental justification and impact assessment on natural components during water management works on deepening and straightening the Alei River bed in three areas within the boundaries of the Tretyakovsky District of the Altai Region. The technical and economic indicators of the deepening and straightening project are presented, and the features of the technological process of the works performed are described. The expected impacts on such natural components as air, water, soil and geological environment, flora and fauna are analyzed. Detailed calculations of waste storage and noise pollution, as well as harm to aquatic biological resources during the period of work are made with an assessment of the expected damage. Compensatory environmental protection measures are proposed. Conclusions are made on the compliance of the planned works with environmental requirements.
