    2222Specific meeting to present and discuss different options for the routing scheme in ORCHIDEE and the associated flood-plains  
    2323 
    24 The presenation discussed in turn: 
     24The different presentations are: 
    2525 - Intro with few news (Philippe P) [attachment:ORC-DEV_Jan2020_Intro.pdf] 
    26  - New routing scheme based on Hydrological Transfert Units for high resolution simulations (Jan) [attachment:DEV-Meeting_presentation_routing_Jan.pdf] 
    27  - Ground water development and links with the routing scheme (Agnes) [attachment:ORCHIDEE_DEV_routing_070120_Agnes.pdf] 
    28  - Flood plain innundation in the ORCHIDEELEAK version [attachment:Lauerwald_20200107.pdf] 
    29  - Toward a new high resolution floodplain scheme (Anthony Schrapffer) [attachment:ORCHIDEE_Anthony_high-resolution-floodplains.pdf] 
     26 - New routing scheme based on Hydrological Transfert Units (HTU) for high resolution simulations (Jan) [attachment:DEV-Meeting_presentation_routing_Jan.pdf]; the new scheme allows to decompose the water demand between ecological flow for the river, agriculture demand (irrigation), Domestic water use and hydro-electricity. It also accounts for dams to sustain the different demands. Key remaining issues are link to parallelisation.  
     27 - Ground water development and links with the routing scheme (Agnes) [attachment:ORCHIDEE_DEV_routing_070120_Agnes.pdf]; i) Agnes tested a new approach for the time constant of the water in the Ground Water reservoir (from Boussinesq equation) but it degrades the river flows; ii) They have inserted a subgrid tiling with lowland and highland units that exchange water (from highland to lowland); this has an impact on the soil moisture and ET of the grid.   
     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.
