Create Flood Data Stack from HAND

Description

Construct Flood Data Stack from HAND.

Usage

Parameters

Parameter NameTypeDirectionData TypeDialog Reference
Flood Data Stack Results FolderRequiredInputFolderThe folder where all the processed data will be stored.
Input Drainage Line Feature ClassRequiredInputFeature LayerDrainage line layer. The fields required are HYDROID, NextDownID, From_Node, To_Node, DrainID.
Input Catchment Feature ClassRequiredInputFeature LayerCatchment layer. Fields needed: HydroID
Input HAND RasterRequiredInputRaster LayerHAND (Height Above Nearest Drainage Point) Raster
Input Minimum Stream Depth RasterOptionalInputRaster LayerLocal min elevation - the elevation of HAND is applied on the nibbled area - using nearest drainage point location as nibble seed.WSE will be created only when MinLocal_Raster is provided,
Input Stream RasterOptionalInputRaster LayerStreamRaster - optional, if provided, it will be used to fill the thalweg cells in case no data were set by the nibble operation.
Apply River RestrictionsRequiredInputBooleanIf Checked, (Apply_River_Restrictions = True) : All the floodplain polygons disconnected with the river line would be removed.
Save RastersRequiredInputLongSave_Rasters = 0 : do not save the rasters> 0 Save rasters: 1 = The RiverDepth raster, 2: G_Depth raster, 4: G_FPZ, 8: G_WSE rasters; 3 = save both river depth and G_Depth rasters. 7= save RiverDepth, G_Depth and G_FPZ rasters, etc.Note. when Save_Raster > 0, it will take about twice as much time for FloodDSMainHandRF process to finish, and the resulting dataset can take up to 100 times diskspace as that when Save_Raster = 0.There is no python reference for this parameter.
Depths to ProcessRequiredInputMultiple ValueList of delta H to be used for the operation. Delta H are defined on the control points. 1;2;3;4;5;6;7;8;9;10;11;12;13;14;15;16;17;18;19;20;21;22;23;24;25;26;27;28;29;30;31;32;33;34;35;36;37;38;39;40;41;42;43;44;45;46;47;48;49
Unit Slope RasterOptionalInputRaster LayerIf provided, river's cross section profile table will be created. The profile table will have the following fields: [StreamID*, A, B, P, R, H*, Q] Unit_Slope_Raster can be created using the [Create Unit Slope] tool under the Arc_Hydro_Tools_Pro.tbx/H & H Modeling/HAND Processing toolset.
