The importance of river hydrodynamics modeling for large scale flood forecasting

The importance of river hydrodynamics modeling for large scale flood forecasting

Contributed by Ayan Fleischmann and Fernando Fan, members of the LSH Research Group Guest Columnist Team River hydrodynamics and hydrographs Satisfactory flood predictions require satisfactory model representativeness of river transport processes. In the past years, the Large Scale Hydrology (LSH) Research Group has carried out many studies regarding the improvement of river hydrodynamics representation in large scale hydrological models (see the list of references at the end of this post) through the implementation of Saint-Venant or Local Inertial flow routing…

Crowdsourced data for flood hydrology – Interview with flood chasers in France and Argentina

Crowdsourced data for flood hydrology – Interview with flood chasers in France and Argentina

Contributed by MH Ramos, member of the IRSTEA Columnist Team A recent paper published in the Journal of Hydrology has drawn my attention: Crowdsourced data for flood hydrology: Feedback from recent citizen science projects in Argentina, France and New Zealand. The paper deals with the use of information from social media in applied sciences and operations, with a focus on collecting photos and videos  to better assess river flows and to improve flood mapping after severe events. It prompts reflections on the way qualitative and quantitative data can…

Making connections through HEPEX – A CSIRO experience

Making connections through HEPEX – A CSIRO experience

By QJ Wang, Andrew Schepen, David Robertson, James Bennett, Durga Lal Shrestha, Yong Song and Tony Zhao members of the CSIRO Columnist Team HEPEX has a reputation as a strong community of like-minded, supportive researchers and practitioners who are collectively bent on significantly advancing the science and applications of ensemble hydrological forecasting. HEPEX provides a unique forum where meeting people and exchanging ideas has the very real potential to open up new, exciting collaborative research opportunities. Indeed, this has been the…

What to look for when using forecasts from NWP models for streamflow forecasting?

What to look for when using forecasts from NWP models for streamflow forecasting?

By Durga Lal Shrestha, James Bennett, David Robertson and QJ Wang, members of the CSIRO Columnist Team There have been a few posts on NWP performance lately, and so we thought we’d add our perspective. We’ve been working closely with the Bureau of Meteorology to extend their new 7-day deterministic streamflow forecasting service to an operational ensemble streamflow forecasting service. One of the fundamental choices we have to make is the source of quantitative precipitation forecasts (QPFs). This is not…

Ensemble forecasting experiments in a medium size tropical basin using MASTER rainfall forecasts

Ensemble forecasting experiments in a medium size tropical basin using MASTER rainfall forecasts

Contributed by Adalberto Meller and Fernando Fan, members of the LSH Research Group Guest Columnist Team As we have seem in our first post, great advances occurred in Brazil in the last years concerning the development of flood alert systems, but still today there is a low number of operational systems in terms of territory coverage, especially those using a probabilistic approach. One of the first researches in Brazil to evaluate ensemble flood forecasts in South America was presented by…
