Last change on this file since 7595 was 7576, checked in by josefine.ghattas, 3 years ago

Integrate routing scheme "highres" developped by Jan Polcher, tested and integrated in ORCHIDEE_2_2 by Lucia Rinchiuso. This corresponds to the revision 7574 of perso/lucia.rinchiuso/myORCHIDEE_2_2_r7481. The developements of the routing scheme from branches/ORCHIDEE-ROUTING at revision 7545 are taken into account.

700	!>\BRIEF This module routes the water over the continents (runoff and
701	!! drainage produced by the hydrol module) into the oceans.
702	!!
703	!! DESCRIPTION (definitions, functional, design, flags):
704	!! The routing scheme (Polcher, 2003) carries the water from the runoff and drainage simulated by SECHIBA
705	!! to the ocean through reservoirs, with some delay. The routing scheme is based on
706	!! a parametrization of the water flow on a global scale (Miller et al., 1994; Hagemann
707	!! and Dumenil, 1998). Given the global map of the main watersheds (Oki et al., 1999;
708	!! Fekete et al., 1999; Vorosmarty et al., 2000) which delineates the boundaries of subbasins
709	!! and gives the eight possible directions of water flow within the pixel, the surface
710	!! runoff and the deep drainage are routed to the ocean. The time-step of the routing is one day.
711	!! The scheme also diagnoses how much water is retained in the foodplains and thus return to soil
712	!! moisture or is taken out of the rivers for irrigation. \n
713	!!
714	!! RECENT CHANGE(S): None
715	!!
716	!! MAIN OUTPUT VARIABLE(S):
717	!! The result of the routing are 3 fluxes :
718	!! - riverflow : The water which flows out from the major rivers. The flux will be located
719	!! on the continental grid but this should be a coastal point.
720	!! - coastalflow : This is the water which flows in a disperse way into the ocean. Essentially these
721	!! are the outflows from all of the small rivers.
722	!! - returnflow : This is the water which flows into a land-point - typically rivers which end in
723	!! the desert. This water will go back into the hydrol module to allow re-evaporation.
724	!! - irrigation : This is water taken from the reservoir and is being put into the upper
725	!! layers of the soil.
726	!! The two first fluxes are in kg/dt and the last two fluxes are in kg/(m^2dt).\n

2401	!! SUBROUTINE : routing_hr_flow
2402	!!
2403	!>\BRIEF This subroutine computes the transport of water in the various reservoirs
2404	!! (including ponds and floodplains) and the water withdrawals from the reservoirs for irrigation.
2405	!!
2406	!! DESCRIPTION (definitions, functional, design, flags) :
2407	!! This will first compute the amount of water which flows out of each of the 3 reservoirs using the assumption of an
2408	!! exponential decrease of water in the reservoir (see Hagemann S and Dumenil L. (1998)). Then we compute the fluxes
2409	!! for floodplains and ponds. All this will then be used in order to update each of the basins : taking water out of
2410	!! the up-stream basin and adding it to the down-stream one.
2411	!! As this step happens globaly we have to stop the parallel processing in order to exchange the information. Once
2412	!! all reservoirs are updated we deal with irrigation. The final step is to compute diagnostic fluxes. Among them
2413	!! the hydrographs of the largest rivers we have chosen to monitor.
2414	!!
2415	!! RECENT CHANGE(S): None
2416	!!
2417	!! MAIN OUTPUT VARIABLE(S): lakeinflow, returnflow, reinfiltration, irrigation, riverflow, coastalflow, hydrographs, flood_frac, flood_res
