River plume at the mouth of the Congo from EOS.

This project is now covered (more or less) by the activities of CHAMFER.

Coastal storm surges annually cause very significant damage to people and property across the globe. Leading on from the next generation of inundation prediction produced by Hydro-JULES, this collaboration (NOC, MetOffice, PML) will develop the UM_JULES coupled model to deliver accurate cyclone flood prediction, quantifying the risk of these hydro-climatic extremes to support long-range planning and policy decisions.

On 4th February 2021 I organised a Zoom meeting with Simon and Eleanor to learn about the Coastal Impacts LTSM2 that is under discussion (see this ppt from June 2020 for LTSM2s). There will be a NOC-led LTSM2 in 2021 looking at sea->land intrusion.

First step: call a science crossover meeting with NOC & PML.

More information:

• Land surface models usually use a land mask to differentiate between the land and the ocean, which are usually simulated by different models coupled together (e.g. JULES and NEMO in standard UK MetO prediction models). In order to be able to simulate coastal outflow (land -> sea) and intrusion (sea -> land), some kind of regular communication of data is required between these models.
  
• Dan Copsey's river outflow points are 1568 of the 1875 NEMO climatological runoff points (see the Ticket details of UM ticket #3405), i.e. more rivers than the 151 of COSCAT. Note that these are not calculationally linked to the river directions layer used by JULES and therefore cannot be assumed to be consistent with it in general.
