Outline

Part A. Overview

  1. What is flood hydrology, and its applications?
  2. Flood probability and risk concepts explained
  3. What are the approaches for flood estimation? [Probabilistic e.g., flood frequency analysis, versus Deterministic viz. rainfall-runoff modelling]
  4. Their pros and cons and when to use each
  5. Uncertainty and reliability

Part B. Flood Frequency Analysis (FFA)

  1. Review of practices in NZ, Australia and elsewhere
  2. Elements of FFA process (6 steps from review of flow data quality to goodness-of-fit)
  3. Inclusion of historic data in FFA (pre-modern records)
  4. Climate change adjustment
  5. Practical aspects and worked examples

Part C. Rainfall – Runoff Modelling

  1. Review of practices in NZ, Australia and elsewhere
  2. Continuous versus single event simulation, distributed versus lumped models
  3. Developing design rainstorms
  4. Model calibration approaches
  5. Worked examples

Part D. Wrap-up

  1. Summary
  2. Q & A
  3. Additional resources/learning
