New Zealand Rainfall and Runoff an update from the steering group Mark Pennington
There is a desire within the NZ technical community to see the development of a comprehensive guideline, similar to the updated Australian Rainfall and Runoff document, for use nationally around New Zealand. This would be a significant undertaking, but would ultimately deliver value to practitioners nationwide. A full description of the project and its background is in the latest Water NZ journal, issue 181 dated September 2013.
In response to this need, the Rivers Group and Water NZ Modelling Special Interest Group have promoted the formation of a steering group for this NZRR project. Seed funding has been made available by Water NZ, and a start has been made with some assessment of needs.
Mark will present an update on progress, and on some proposed ways to continue the project forward towards ultimate completion. Input from attendees is invited.
Mark Pennington is an engineer who works for Tonkin & Taylor in Tauranga. He currently chairs the Rivers Group, and is a long-standing committee member of the Modelling Special Interest Group. He has a professional background in hydrological processes and in channel hydraulics.
High intensity rainfall estimation in New Zealand Graeme Horrell
Graeme will present back ground to the development of High Intensity Rainfall Development System (HIRDS) versions 1, 2, and 3 as well as the assessment of the 2010 version 3 by Regional Councils. This will be followed by a brief comparison with Council guidelines for storm water runoff, and future developments for HIRDS.
Graeme Horrell is an engineering hydrologist with NIWA for the last 5 years, working mainly as a consultant on water management issues, previously 18 years at Environment Canterbury as the senior water resources scientist, following a few years in the hydrology section of Power Division of Ministry of works and earlier many years measuring river flow and rainfall in the South Island including a summer in the Antarctic.
