NSW pre-burst visualiser

Full storm temporal patterns (pre-burst + burst) for Australian Rainfall & Runoff, from the ARR Data Hub.

Get the JSON from the Data Hub with type=json, for example this location's JSON. If you don't load a CSV, the page fetches the burst patterns for the location's temporal pattern region.

How the full storm is built

  1. Burst. The 10 point temporal patterns for the location's region (from the Data Hub PointTP code), duration, and AEP bin: frequent (50%, 20%), intermediate (10%, 5%), or rare (2%, 1%). Each one is scaled to the burst depth from the selected IFD table.
  2. Pre-burst. The NSW 2026 recommended pre-burst pattern for the duration and AEP (Data Hub RecPreburstTP). It is scaled to pre-burst ratio × burst depth and placed right before the burst.
  3. Normalised views. "% of burst" keeps burst increments summing to 100% and pre-burst increments summing to 100 × ratio%. "% of storm" rescales both so the whole storm sums to 100%.

The Data Hub works out its pre-burst depths from the 2030 baseline IFD. If you pick another IFD table, or override the burst depth, this page applies the same ratio to that depth. Check the results against ARR guidance and the Data Hub before you use them in design.
