v132 v133 269 269 === Hydraulic architecture === 270 270 271 Describes r7829. A new numerical solution for hydraulic architecture has been implemented in the hydrol.f90 module of ORCHIDEE trunk. This hydraulic architecture is controlled thanks to a set of flags. The flag '''ok_hydrol_arch''' imposes the model to solve a hydraulic architecture . By default, the hydraulic architecture developed in ORCHIDEE-CAN is solved (in hydraulic_arch.f90 module). To use the hydraulic architecture developed following Tuzet et al. (2017) model, another flag needs to be set : '''is_tuzet_hydrol_arch'''. When this hydrualic architecture is set up, several options can be added.271 Describes r7829. A new numerical solution for hydraulic architecture has been implemented in the hydrol.f90 module of ORCHIDEE trunk. This hydraulic architecture is controlled thanks to a set of flags. The flag '''ok_hydrol_arch''' imposes the model to solve a hydraulic architecture (note that '''energy_control''' should be set to 1 to control this). By default, the hydraulic architecture developed in ORCHIDEE-CAN is solved (in hydraulic_arch.f90 module). To use the hydraulic architecture developed following Tuzet et al. (2017) model, another flag needs to be set : '''is_tuzet_hydrol_arch'''. When this hydrualic architecture is set up, several options can be added. 272 272 273 273 Two different ways of solving root absorption are implemented. One with low calculation time using a dynamic resistance or another one solving radially Richards' diffusion equation around the roots. The flag '''ok_tuzet_hydrol_arch_muff''' permits to activate the radial resolution around the roots (by default, it is set to False and the dynamic resistance is used).
