The Purpose Of This Contract Is: 1) To Determine, From A Theoretical Point Of View, The Potential Effects Of Sediment Concentration On Fish Communities And Macrophyte Populations Both In The General Area And In The Particular Case Of The Section Bottom And End Of The Ebro River; 2) Obtain A Predictive Model On The Response Of Some Of The Species And Fish Communities Present In The Lower And Final Section Of The Ebro River To Sediment Concentration; 3) Establish Maximum Sediment Concentration Thresholds Above Which Native Species Can Be Affected So That, In The Event Of A Sediment Release Exercise From The Reservoirs Located Upstream, Guidance Can Be Given To The Maximum Turbidity Levels To Be Reached.
