Tenders Are Invited For Topographical Services – Update Of The Inland Water Risk Map in Hungary

Work Detail

Topographical Services – Update Of The Inland Water Risk Map. Ii.2.4) Description Of The Public Procurement: (Nature And Quantity Of The Construction Investment, Procurement Of Goods Or Services, As Well As The Definition Of Needs And Requirements) Update Of The Inland Water Hazard Map (In The Framework Of The Project Kehop_Plusz-1.2.21-24-2024-00001) Regarding The Development Of The Inland Water Hazard Mapping Methodology, Several Concepts Were Created In Various Research Workshops, However Before 2015, A Map Covering A Significant Part Of The Country Was Not Produced, With The Exception Of The Pálfai Inland Water Hazard Map. Flood Risk Mapping And Preparation Of A Strategic Risk Management Plan (Keop-2.5.0/B/09-12-2013-0001) C. In 2015, In The Framework Of A Tender, The High-Resolution Inland Water Risk Mapping Of Agricultural Areas With Unfavorable Water Management Status In The Lowland Areas Of Hungary (Great Plains, Small Islands, Scattered Areas) Was Developed. A Summary Study And A Complex Inland Water Hazard Probability Map Of Hungary Was Completed. Development Of The Inland Water Hazard Map In The Methodology Previously Developed Within The Framework Of The Ákk, There Is Also The Possibility Of Using New Factors/Auxiliary Variables. The Following Factors Must Be Taken Into Account During The Revision Of The Inland Water Risk Map, For Which The Following Geospatial Data Are Provided By The Ovf And The Water Directorates: • Exact Delimitation Of The Investigation Area; • National Long Time Series Groundwater Data; • National Long Time Series Meteorological Data; • Paper And Digital Inundation Data; • Improved Ddm; • Digital Sewer Coverage (Inland Drainage Sewer Network, Dual-Function Sewers, Structures, Pumping Capacity, Water Transport Capacity Of Canals, Gravity Discharge Capacity, Etc.); • Digital Overlay Of Irrigated Areas; • Digital Overlay Of Permanent And Temporary Inland Water Reservoirs; • Limits Of Flood Plains, Wave Fields, Digital Overlay • Demarcation Of Floodplain Areas, Digital Overlay • Demarcation Of Permanent And Temporary Inland Water Reservoirs, Digital Overlay • Transfer Of Other Data Relevant To The Investigation (Long Time-Series Readiness Level Data Series; Data On The Durability Of Inundation, Inland Water Systems, Inland Water Basins And Section Boundaries, Etc.). • Vizig-Treated Canals And The Water Control Structures On Them January 1, 2023-2025. Tabular Maintenance Data For The Period Between December 31, 2026, Which The Customer Can Hand Over On April 10, 2026. • Polygons Of Previously Demarcated Areas Suitable For Water Retention. • Advanced Data Of Water Retained In Vizig-Treated Canals. Tasks To Be Carried Out In The Context Of The Further Development Of The Inland Water Hazard Map: • Using The Data Of The Canal And Construction Maintenance Works, The Clarification Of The Complex Inland Water Hazard Map, As Well As The Review Of The Inland Water Hazard Scenarios (Strategic Versions). • Pot Delimited In The Period Before The Project
