The importance of rainfall timestep for flood forecasting

Many communities on the east coast of Australia are subject to flash flooding. Due to the convective rainfall typical of Eastern Australia, combined with local catchment characteristics, flash flooding can be very intense and occur with little warning. Flash flood forecasting is used to predict the impact of these high rainfall events before they occur. A typical Flash Flood Forecasting System (FFFS) uses meteorological forecasts, soil moisture estimates, sea level conditions and numerical modelling to understand how much rain will turn to runoff and how it will flow through a catchment. Traditional systems in Australia have used the meteorological forecasts within the Australian Digital F

Flood forecasting systems

Forecast data is great, but only great if it can be used to its full potential and can be used to confidently provide insight. So how can we do this? For JBPacific, Delft-FEWS is the preferred approach. Delft-FEWS is the same ‘open data handling platform initially developed as a flood forecasting and warning system’ used by the Bureau of Meteorology. What data do we use? Our flood forecasting systems use Delft-FEWS to read in weather forecasts directly from the Bureau of Meteorology, including data on forecast rainfall, wind, temperature and tide, as well as the newer Rainfields product which provides an ensemble of rainfall forecast. In addition to forecast information, we also combine obse

JBPacific venture into the maritime sector

JBP project catalogue is expanding into the maritime sector. JBP have recently showcased a lot of our climate disaster adaptation studies and capabilities including a suite of expertise in cyclone modelling, extreme weather forecasting systems, flood mapping, coastal erosion modelling, and the list goes on... Not only do our capabilities lie in the theoretical modelling space but in the past three years we have taken on the full design of a spectrum of structures in the coastal environment. Most of which have now been constructed or currently awaiting to be taken through to construction. As a summary, the following are a short overview of the structures we have designed; geotextile sand co

Returning to the engineering world

For the last five years, I was working in academia on fluvial geomorphology and river restoration research projects. Following completion of my PhD, I decided to move into the consulting industry, and started this new part of my career at JBPacific in November 2019. I have spent a significant part of my professional life engaging in research, expanding my knowledge on fluvial geomorphology with an emphasis on improving river habitat conditions. This helped me to gain solid background in stream naturalization, such as applying in-channel structures (e.g., pool and riffles) to enhance channel stabilization and to improve hydraulic, morphologic, and biological conditions of urban streams.
