HYPE Model Documentation

If you have an older model set-up (using HYPE version before 5.17.0) and want to upgrade to use the AtmdepData.txt file here are some tips on how to get started. Older models had atmosperic deposition given in GeoData.txt and par.txt. Both type of atmospheric deposition can be transfered to the new file.

In the parameter file deposition of phosphorus could be given. They can be transferd like this: drydeppp kg km-2 ts-1 dry deposition of PP Replace with PP_DD_L1..PP_DD_Lnluse unit? same value for all subbasins. wetdepsp µg L-1 wet deposition of SP Replace with SP_WD same value for all subbasins, unit changed? wetdepspl kg km-2 ts-1 wet deposition of SP on water surfaces Replace with dry deposition in AtmdepData.txt; SP_DD_V3 same value for all subbasins.

In GeoData.txt nitrogen deposition was given by subbasin and vegetation type and/or month. They can be tranfered to the new file like this: wetdep_n ug/L wet deposition of inorganic nitrogen, concentration of precipitation Replaced by column IN_WD in AtmdepData.txt. Note the unit change to mg/L. drydep_n1 kg/km2/d dry deposition of inorganic nitrogen on vegetation type 1 (open) Replaced by column IN_DD_V1 in AtmdepData.txt drydep_n2 kg/km2/d dry deposition of inorganic nitrogen on vegetation type 2 (forest) Replaced by column IN_DD_V2 in AtmdepData.txt drydep_n3 kg/km2/d dry deposition of inorganic nitrogen on vegetation type 3 (water) Replaced by column IN_DD_V3 in AtmdepData.txt. Unit?? per timestep? deploadn1-deploadn12 kg/km2/d total deposition of inorganic nitrogen on water, January - December Replaced by adding as dry deposition in AtmdepData.txt; columns IN_DD_M1_V3 … IN_DD_M12_V3.
