Richmond Valley Flood Study 2023 - Final Report - Volume 2 consists of design flood mapping. The maps contain the following model outputs for the 5%, 2%, 1%, 1%CC, 0.2% & PMF AEP events- ~Peak flood levels (mAHD) ~Peak flood depth (m) ~Peak flood velocity (m/s) ~Critical events durations (Region H only) The following processed model outputs are also included- ~Peak flood (classified) hazard (1%, 0.2% and 1%CC AEP events) ~Flood function mapping (1% and 0.2% AEP events) ~Flood islands ~Flood Planning Levels (mAHD)

Dataset – Richmond Valley Flood Study 2023 (Vol.1) (PDF) Dataset – Richmond Valley Flood Study 2023 (Vol.2) (PDF) – includes design flood mapping Dataset – Spatial Data (.ZIP) – includes spatial mapping for design floods (5%AEP, 2%AEP, 1%AEP, 0.2%AEP & PMF), and design floods with climate change. Each design flood includes – peak flood depth (m), peak flood height (mAHD), peak velocity (m/s), velocity vectors (degrees), hazard categories (H1-H6). Additional flood planning maps include – residential Flood Planning Level (1%AEP+CC+500mm freeboard), flood islands, and Roads with Flood Levels. |
