Tenders Are Invited For Engineering Services – Regional Update Of The Hwgk - Gf 16404 Glatt

Engineering Services – Regional Update Of The Hwgk - Gf 16404 Glatt. Goal: Updating The Flood Hazard Maps In The Catchment Area Of ​​The Glatt, Which Flows Into The Neckar. Waters To Be Calculated: 71.6 Km. Additional Bodies Of Water To Be Considered: 9.9 Km. Area Size Of Total Hydraulic Catchment Area: 247 Km2. Support Points In Hydterrain (Estimated): 184 Million Units. Raster Processing Size (Estimated): 46 Km2. /// The Procedure Is Determined By National Regulations For The Hwgk Project And Includes The Following Essential Points: Acquisition And Processing Of The Geobase And Geotechnical Data Provided, The Hydrology Data (Bfgm) And Checking The Survey Data. / Check The Digital Terrain Model With Integrated Water Hose (Tin/Terrain) (Basis: Laser Scan Data From Aerial Surveys 2016 Ff) And, If Necessary, Refine It To Include Terrain Structures That Are Not Included And Measured Building Structures. Preparation Of Data For The Creation Of Hydraulic Models. / The Hydrological Work Was Carried Out Using The Basic Hydrological Model Bfgm And An Fgm Model (Extension Of The Fgm Program For Area-Detailed Precipitation-Runoff Modeling In A Complex Catchment Area From The Flood Analysis And Calculation Software Package From Lubw/Kit). They Include The Adoption Of The Raw Model For The Study Area Provided By The Client, Which Is Technically Executable But Not Yet Adapted To The Discharge Characteristics Of The Area, The Expansion Of The Raw Model Into A Detailed Model Through The Integration And Parameterization Of Additional Nodes, The Adaptation And Validation Of The Discharge Characteristics Of The Area Based On Existing Hqt Values, The Calculation Of Discharge Hydrographs With 3 Model Variants For At Least Five Annual Periods Each, As Well As Data Storage And Provision Of The Results And The Model Access Databases, Graphical Longitudinal Sections And Fgm Files. The Results Will Be Made Available. / Hydraulic 2D Models Must Be Created Using The Laser_As-2D / Hydroas Software Package. All Hydraulically Relevant Structures In And Around The Water And On The Foreshores Must Be Taken Into Account. / Calculation Of Hydraulics (Non-Stationary) With Hydroas According To A Defined Procedure For Updating The Hwgk (Hq10, Hq50, Hq100, Hq100ohrb, Hq1000 And Hwextrem In Sections) / Evaluation Of The Modeled Calculations With Regard To The Representation Of The Hydrological Calculation Variables. Derivation Of Corrected Flood Areas, Water Level And Flood Depth Grids, Recording Of Factual Data And Geometries / Gauge 00105 Hopfau / Glatt Is Located In The Processing Area. A Level Model Has Already Been Created In Advance For This State Gauge That Is In Operation. This Is Provided And Must Be Integrated. / Several Hw Protection Measures Are Being Planned And Constructed In The Area. These Must Be Taken Into Account During Processing. / Documentation And Coordination With The Client / For The Processing Of This Project W
