DBH Model Processing of Output Files

· Input data setting

In source code the main program SIB_DHM.f, input data can be set as ‘no change’ and ‘with change’ scenarios. nc_cl = 0/1: no/with linear change in atmospheric forcing data, nc_ia = 0/1: no/with linear change in irrigation area, nc_vg: no/with linear change in vegetation conditions.

data nc_cl,nc_ia,nc_vg /1,1,1/ ! Here (=0, no change, other, change)

Please note parameters for setting no linear change scenarios should be put at ./ATM_INPUT_DATA/ANALYSIS/ . The required parameters are described in analysis.txt.

· Scenario analysis

Assume there are results of six scenarios: Allchange_HI, noclimate_HI, novegetation_HI, noirrarea_HI, Nochange_HI, and Noch_rept60_HI. ./ANAsce/HIseries_lv2_rS1.f will output the contributions to hydrological change (i.e. the difference between scenarios). ./ANAsce/HIdischarge_6files.f output the discharge comparisons.

Note: Only several typical analysis tools are provided here. The analysis processes should correspond to the research purpose.

Difference scenarios can be performed with the DBH model system. All the scenario simulations could share the same time varying input at directory ./ATM_INPUT_DATA/ . Difference scenario simulations could simultaneously run. The ./MODEL/ directory could be duplicated as a new directory with the name of scenario name, then compile the DBH model in the new directory. The scenario result could be analyzed after running the simulation of all the scenarios.
