Tenders Are Invited For Hydrodynamic Modeling Of The Tributaries For The Weser Adaptation

Hydrodynamic Modeling Of The Tributaries For The Weser Adaptation. The Following Tasks Have To Be Processed For The Tide-Affected Areas Of The Tidehunte, The Lesumwümmehamme River System And The Ochtum River: (A) Preparation: Processing, Viewing And Description Of The Input Data For The System Status Of The Hydrological Year 2020 (01.11.2019 Up To And Including 31.10.2020) . (B) Model Construction: Creation Of A Numerical Model Each For The Tidehunte (3D), The Lesumwümmehamme River System (2D) And For The Ochtum (2D) A Total Of 3 Independent Models. Delft3dflexible Mesh (Delft3dfm) Is To Be Used As The Model System In Order To Enable Subsequent Use/Further Use Of The Models Created By The Baw. (C) Simulation: Determination Of The Hydrodynamic System Parameters (Water Level, Flow Velocity, Transport Capacity, Flow Rate) For Four Different Scenarios (Current Planning Status, Expansion Of The Outer Weser, Expansion Of The Lower Weser North, Overlaying Of The Expansion Of The Outer Weser And Lower Weser North) Over 2 Springnipp Cycles Each. For The Hunte, Two Other Scenarios With Sea Level Rise For Salt Intrusion Can Also Be Expected. (D) Hydraulic System Analysis: Determination Of The Tidal Characteristics Of The Water Level, The Current And The Transport Capacity As Well As Their Changes Due To The Planned Expansion Variants. (E) Transfer Of The Model Result Data And The Models Including A Transfer Protocol With A Data Description. (F) Documentation: Preparation Of A Report Summarizing All Investigations, Results And Methods Used.
