| 16 | | - The need to test/update routing_PP (pre-processor) in order to work with icosaedric grid (especially for the number of neighbours) |
| 17 | | - Potentially test the "efficiency" of routing_PP with a very large number of processor to gain speed (currently several hours in one node for a regional configuration) |
| 18 | | - NEED to test the routing scheme in ORCHIDEE with respect to the intrinsic and numerical properties of the scheme in order to better understand why the results seems to critically depend on the time step in routing and possibly on the number of HTU (hydrological Transfert Units) per grid box (a parameter that can be chosen), etc... For that |
| 19 | | - Need to check/update the "force_routing" program in order to do simple test with a uniq input (drainage and runoff) pre-calculated by ORC. |
| 20 | | - Need to do some elementary tests on the different configuration for the time step, the choise of the initial high resolution description of the basins, etc |
| 21 | | - Yan suggest |
| 22 | | - EM suggest to |
| 23 | | - Agnes wans to contr |

| | 16 | - Construction of the Hydrological Transfer Units (HTUs) done offline with the pre-processing routing: Routing_PP |
| | 17 | - Need to test/update routing_PP in order to work with icosaedric grid (especially for the number of neighbours) |
| | 18 | - Potentially test the "efficiency" of routing_PP with a very large number of processor to gain speed (currently several hours in one node for a regional configuration) |
| | 19 | - Test the impact of the max number of HTUs per grid cell on the overall routing scheme |
| | 20 | - Routing scheme in ORCHIDEE |
| | 21 | - NEED to test the intrinsic and numerical properties of the scheme in order to better understand why the results (river discharge for the Amazon river at Obidos) seems to critically depend on the time step in routing and possibly on the number of HTUs per grid box, etc... For that a specific "unitary" test with a pulse of rain (or runoff) can be done. |
| | 22 | - To ease the different "unitary test" Jan will update the "force_routing" routine in order to perform some tests with allways the same inputs of water. |
| | 23 | - Agnes also suggested to test the mumeric of the routing scheme with only the "river reservoir" |
| | 24 | ==> Different tests on the time step, the choise of the HTUs max per grid, the calculation of the topoindex, etc to be done |
| | 25 | - Several people want to help / contribute |
| | 26 | - Agnes wants to apply the scheme for the Seine river basin |
| | 27 | - Thomas will help with the icosaedric grid for routing_pp |
| | 28 | - Emannuel can advise on the numerics |
| | 29 | - Yan will help with respect to reproducing / understanding the difference between routing the water at the highest resolution (using the original basin description from Hydroshed for instance) and the routing a coarser ORCH model resolution. |
