28 | | - Flood plain innundation in the ORCHILEAK version (Rony Lauerwald) [attachment:Lauerwald_20200107.pdf]; Rony implemented and tested a new approach for the floodplain based on a threshold (Bankfull) over which the river start to fill the potential floodplain; It largely improves the dynamic of flooded area over the Amazone. Such scheme will be transfered into the TRUNK together with Agnes. |
29 | | - Toward a new high resolution floodplain scheme (Anthony Schrapffer) [attachment:ORCHIDEE_Anthony_high-resolution-floodplains.pdf] Anthony is implementing a potential new floodplain scheme working on the "Paraguay river and flooding region" in South America; It is based on the propagation of a flooding waves depending on topography. |

Ongoing work with more options to come. |
| 28 | - Flood plain innundation in the ORCHILEAK version (Rony Lauerwald) [attachment:Lauerwald_20200107.pdf]; Rony implemented and tested a new approach for the floodplain based on a threshold (Bankfull) over which the river start to fill the potential floodplain (pre-determined); It largely improves the dynamic of flooded area over the Amazone. Such scheme will be transfered into the TRUNK together with Agnes. |

On-going work that will test several hypothesis for floodplain dynamics. |
