Overall Approach Phase I: Program Design • Design an approach for a comprehensive rain/flow/stage statewide monitoring network with a coverage of major and local Data tributaries • Design a modeling approach and standards. This includes inland watersheds, transition/coastal zones, and the Gulf • Ensure coordination between Data & Modeling TAG and other LWI TAGs • Ensure coordination between Data & Modeling TAG and local entities 13 L O U I S I A N A W A T E R S H E D I N I T I A T I V E W O R K I N G T O G E T H E R F O R S U S T A I N A B I L I T Y A N D R E S I L I E N C E
Overall Approach Phase II: Program Implementation • Ongoing quality control/assurance of modeling and data products Data • Ongoing assessment of mitigation project outcomes and impacts • Develop a sustainability plan (long-term maintenance, and access) for monitoring and modeling products • Ensure coordination between all LWI TAGs • Ensure coordination between Data & Modeling TAG and local entities 14 L O U I S I A N A W A T E R S H E D I N I T I A T I V E W O R K I N G T O G E T H E R F O R S U S T A I N A B I L I T Y A N D R E S I L I E N C E
Data Collection Approach Static Data • LiDAR • Bathymetry Data • Hydraulic Structures Dynamic Data • Rain gauges & Radar Products • Stage & Flow Gauges • Others (Wind, WQ, GW) 15 L O U I S I A N A W A T E R S H E D I N I T I A T I V E W O R K I N G T O G E T H E R F O R S U S T A I N A B I L I T Y A N D R E S I L I E N C E

Dynamic Data WHAT? • Hydrologic monitoring to support watershed-to-community-scale flood mitigation & development planning • Key variables: Rainfall; Water Level; Flow Rate WHY? Agree on our objectives • Model Setup, Calibration and Validation • Evaluation of Project Impacts • Project Operations • Real-Time Warning and Forecasting Systems HOW? • Modern Sensor Technologies 18 L O U I S I A N A W A T E R S H E D I N I T I A T I V E W O R K I N G T O G E T H E R F O R S U S T A I N A B I L I T Y A N D R E S I L I E N C E
Dynamic Data: We are hydrologically under-monitored ! • Significant gaps: some watersheds and streams are completely unmonitored • Northeast & southwest Louisiana are particularly under-monitored • Recognize the need for long- term plan for maintenance & operation (need for partnership with local and regional entities) USGS Flow/Stage Network 19 L O U I S I A N A W A T E R S H E D I N I T I A T I V E W O R K I N G T O G E T H E R F O R S U S T A I N A B I L I T Y A N D R E S I L I E N C E

How many gauges and where? Depends on the purpose ... • Focus on main rivers and major tributaries only? Or, • Also support predictions at smaller tributaries • Should we focus more on urban areas? • Capture complex flow behavior (e.g., reverse flows, urban hydrology) 21 L O U I S I A N A W A T E R S H E D I N I T I A T I V E W O R K I N G T O G E T H E R F O R S U S T A I N A B I L I T Y A N D R E S I L I E N C E
Design Approach: Iterative, Stakeholder-Driven Recommended framework for each region (to be implemented by the professional teams): 1. Develop an initial design 2. Collect feedback from stakeholders 3. Develop a revised design 4. Deploy gauges 5. Develop data analytics 6. Periodic review and adjustment of the design as needed 22 L O U I S I A N A W A T E R S H E D I N I T I A T I V E W O R K I N G T O G E T H E R F O R S U S T A I N A B I L I T Y A N D R E S I L I E N C E
Tier-Based Design for Placing Stage and Flow Gauges Tier 1 : Absolute necessary gauges Tier 1 : Program-duration gauges Tier 2: Enhanced coverage Tier 2 : Permanent gauges Tier 3 : Ideal coverage 23 L O U I S I A N A W A T E R S H E D I N I T I A T I V E W O R K I N G T O G E T H E R F O R S U S T A I N A B I L I T Y A N D R E S I L I E N C E
Smarter Designs: New Sensor Technologies Ultrasonic (Stage) Radar (Stage) Acoustic Doppler (Flow) Tier 1 : Constrained coverage of flow gauges at strategic locations Tier 2 : Denser coverage of stage gauges 24 L O U I S I A N A W A T E R S H E D I N I T I A T I V E W O R K I N G T O G E T H E R F O R S U S T A I N A B I L I T Y A N D R E S I L I E N C E
