The Investment Objective Consists In: 1. The Restoration And Renaturation Of An Old Bifurcation Arm To The Bala Arm That Would Create The Premises And Conditions Both For Navigation (As An Alternative Navigation Option For The Old Danube, In Limited Cases With Very Low Flows Of The Danube) And For The Upstream/Downstream Migration Of Sturgeons, Which Also Includes: - 1.A. Relocating The Bifurcation Area Further Upstream From The Current Location (Approx. At Km 347) And Changing The Angle Of The Bifurcation To Avoid The Influence Of The Pârjoaia Rock On The Direction Of The Water Currents That Direct The Flow Of Water Towards The Bala Arm; - 1.B. For Environmental Protection: Creating A Natural Protection Of The Bed Of The Restored/Renatured Arm To Limit Its Erosion And Evolution Over Time (Limitation Of Morphological Changes At The Level Of The Bifurcation); - 1. C. For Environmental Protection: The Creation Of A Roughness Of The Restored Arm That Ensures The Increase Of Resistance To Water Flow, Which Will Lead To The Redistribution Of The Flow At The Level Of The Bifurcation In Favor Of The Increase Of The Flow On The Old Danube And To The Generation Of A Flow Velocity On The Arm That Is Compatible With The Migratory Capacity Of Aquatic Fauna (Especially Sturgeons) As Well As With Navigation; 2. Raising The Level Of The Existing Bottom Sill On The Bala Arm From 0 M Mnc To 6.5 M Mnc In Order To Generate The Flow Resistance Necessary To Divert The Waters Towards The Old Danube; 3.
