Feasibility Study – Geru-Technical-Economic Documentation Development Services, Mixed Investment Project Phase, For The Investment Objective Proposed Works Related To The Hydrographic Space Delimited By The Tributaries Of The Siret River, Development Of The Geru River And Its Tributaries, Galați County,. The Purpose Of The Application Of This Procedure Is The Award Of The Service Contract For The Development Of Technical-Economic Documentation (Mixed Investment Project Phase) For The Investment Objective Proposed Works Related To The Hydrographic Space Delimited By The Tributaries Of The Siret River, Development Of The Geru River And Its Tributaries, Galați County. The Need And Opportunity To Promote The Investment Works Is Supported (Justified) Both By The Extent Of The Damage Caused By The Flood On The Suhu River And Its Tributaries, As Well As By The High Degree Of Risk Highlighted By The Flood Risk Maps For Different Probabilities Of Exceeding The Flows. Taking Into Account The Specificity Of The Problems Reported In The Basin, The Designer Will Analyze Through Hydraulic Modeling The Effect Of The Measures Envisaged On The Floodability Of The Studied Areas And Has Full Freedom To Propose Structural And Non-Structural Measures (Transversal/Longitudinal Accumulations, Bed Recalibrations, Construction Of Dykes, Relocation Of Dykes, Embankment Elevations, Retaining Walls, Etc.) With The Role Of Reducing The Damage Caused By Floods And Removing The Effects Of Floods From Localities. Depending On Hydraulic Modeling And Field Studies, A Technical Expertise Of The Existing Reservoir And Hydrotechnical Works Under The Administration Of A.B.A. Is Required. And If The Technical Solutions Require It, Their Relocation Or Decommissioning Will Be Analyzed. The Designer Will Analyze, Without Being Limited To, The Appropriateness And Effectiveness Of The Measures Identified And Mentioned In The Flood Risk Management Plan - A.B.A. Prut–Bârlad Approved In 2023. The Following Work Proposals Will Be Considered, Which Have The Main Role Of Reducing The Damage Caused By Floods And Removing The Towns From The Effects Of Floods: I. Development Of The Geru River And Its Tributaries, County. Galaţi: - Riverbed Development In A Length Of L = 57.0 Km - 3 Non-Permanent Accumulations, As Follows: I.1. Development Of The Geru River, Confluence Siret - Place. Mândreşti: - Development Of The Geru River Bed, L = 42 Km; - Realization Of A Non-Permanent Accumulation Upstream Valea Mărului I.2. Development Of The River Jepea (Cudalbi): - Development Of The Bed Of The River Jepea (Cudalbi), L = 5 Km; - Realization Of A Non-Permanent Accumulation Upstream Cudalbi Locality I.3. Development Of The Gologanu River: - Development Of The Gologanu River Bed, L = 10 Km; - Construction Of A Non-Permanent Accumulation In The Right Of Mănăstiri Gologanu Estimated Flood Defense Works Are: Three Non-Permanent Accumulations (Upstream Of Valea Mărului Locality, Upstream Of Cudalbi Locality, In The Right Of Mănăstiri Gologanu) Bed Regularization, Flood Protection Dykes If Necessary, Works On Control Sediments, Etc., According To Stas 4273/1983 And Stas 4068/2/1987 Respectively Class Iii Of Importance, Having The Calculation Flow Under Normal Conditions Of Execution = The Flow With The Annual Probability Of Exceeding 2% And The Verification Flows: - With The Probability Of 0.5 % For B
