conference contribution
posted on 2018-02-12, 15:09 authored by Eduardo von Sperling, Marcos von Sperling, Nayana G. SilvaThe paper describes the issues of water quality in low flow reaches downstream energy generation dams. These reaches
should maintain a minimum water flow in order to guarantee adequate ecological conditions in the water body. A case
study is presented with respect to the longest low flow reach in Brazil, focusing mainly on environmental and regulatory
aspects. Water quality in this reach should be enhanced by the construction of some intermediate dikes, which will allow
the sedimentation of particulate matter and the formation of small reservoirs for the growth of aquatic species. A concern
remains only with phosphorus concentrations, since the environment will change from a lotic to a lentic condition.
