GTSMR
Revised Generalised Tropical Storm Method for estimating PMP

The Revised Generalised Tropical Storm Method (GTSMR) is applicable to those parts of Australia affected by tropical storms and divides the region into 3 parts: the coastal zone and the inland zone with an additional winter only zone covering southwest Western Australia. The maximum duration covered by this method is 120 hours days in the coastal zone in summer and 96 hours for all other zones and seasons.

The development of the GTSMR is documented in the "Revision of the Generalised Tropical Storm Method of Estimating Probable Maximum Precipitation"(2003), Hydrology Report Series, Report No. 8 (HRS8). A catalogue of the significant rainfall occurrences used as a basis for the GTSMR is available in Hydrology Report Series, Report 9 (HRS9).

This new method supersedes the GTSM as described in Kennedy and Hart (1984).

These may be obtained by either purchasing a guide on CD or by requesting a report from HAS.
