Helping shape a new flood forecasting service in The wellington region, new zealand

Helping shape a new flood forecasting service in The wellington region, new zealand

Contributed by Michael Cranston (RAB), Andy Brown (Greater Wellington Regional Council) and Bapon Fakhruddin (Tonkin and Taylor). The flooding challenge in Wellington Greater Wellington Regional Council (GWRC) are embarking on a programme to establish improved flood forecasting services across the Wellington Region on New Zealand’s north island. Flooding is considered New Zealand’s number one natural hazard with flood emergencies estimated to have cost $17 million a year in insurance payments and $15 million in emergency management expenditure between 1968 and…

HEPEX Advances and Applications at MODSIM

HEPEX Advances and Applications at MODSIM

At the 23rd International Congress on Modelling and Simulation (MODSIM2019), from 1-6 December 2019 in Canberra, Australia, a HEPEX session highlighted recent work in hydrometeorological forecasting. Seline Ng from CSIRO discusses HEPEX highlights from MODSIM2019: We are glad to report that our session titled “Advances and applications in hydrometeorological forecasting” at the recent MODSIM2019 conference in Canberra, Australia went well, with a strong showing by the Australian Bureau of Meteorology (BOM), CSIRO Land & Water and University of Melbourne. Ours…

Flash flooding is a serious threat in the UK – here’s how scientists are tackling its prediction

Flash flooding is a serious threat in the UK – here’s how scientists are tackling its prediction

Contributed by Christopher J White, University of Strathclyde ; Michael Cranston, RAB; Laura Kelly, University of Strathclyde ; Linda Speight, University of Reading. It’s becoming a familiar scene on the news: sodden British people wading through streets up to their knees in flood water. From Stirling to Sheffield, many parts of the UK in 2019 felt the impact of severe surface water flooding – often referred to as flash flooding – that followed torrential rain. As the climate changes and the…

Large ensemble simulations for the study of extreme hydrological events

Large ensemble simulations for the study of extreme hydrological events

Contributed by Karin van der Wiel, KNMI*. The investigation of extreme hydrological events is often limited by the length of observed records or model simulations. For this reason many statistical extrapolation methods have been developed. In a recent GRL paper we advocate a novel method for the study of extreme events, which does not rely on such extrapolations (Van der Wiel et al., 2019). In this blog post I invite you to take a slight step outside the HEPEX world…
