1. Create WSE And Depth Raster

Description

This tool creates water surface elevation (WSE) and ponded depth (PD) rasters from stage recorder location(s) data by interpolation, using the interpolation technique specified by the user in the Interpolation Methodpull-down. If the WSE raster prefix is not provided, WSE rasters are not saved. If the configuration file is not provided, default ArcGIS surface interpolation parameters are used for the selected interpolation method. If only one gage is available for interpolation, the interpolation method entry is ignored and a horizontal water surface elevation is created instead.For additional information, refer to the Arc Hydro - Hydroperiod Tool document.

Usage

Parameters

Direction	Type	Parameter Name	Data Type	Dialog Reference
Input	Required	Input DEM Raster	GPRasterLayer	DEM raster used for definition of the terrain surface. Ponded depth is measured from this elevation representation. It is also used to define the cell size and extent of the analysis (the interpolated water surface elevation will be limited to the extent of the DEM).
Input	Required	Input Monitoring Point Feature Class	GPFeatureLayer	Point feature class of locations that will be used for water surface interpolation. If there is a selection on the points, only selected points will be used in the interpolation process. If nothing is selected, all points will be used.
Input	Required	Input Monitoring Table	GPTableView	Monitoring table that will be used for water surface interpolation. If there is a selection on the table, only selected stages will be used in the interpolation process. If nothing is selected, all stages will be used. Three types of tables can be used as input: Time series: requires fields “TSValue”, “TSTime”, and “FeatureID”. Frequency series: requires fields “FreqValue”, “FreqCode”, and “FeatureID”. Stage series: requires fields “StageValue” and “StageCode”.
Input	Required	Interpolation Method	GPString	Viable interpolation methods. Only one can be selected for any given run.
Input	Optional	Input Configuration File	DETextFile	Optional configuation (txt) file with custom parameters for specified interpolation method. If one is not provided, standard parameters for the selected interpolation method will be used. This file format must exactly match the selected method. See tool design document for examples of file structures for each method.
Input	Required	Output Folder	DEFolder	Target folder where tool outputs are stored. The folder must exist.
Input	Required	Output Ponded Depth Raster Prefix	GPString	Prefix used for naming the ponded depth rasters. It should be limited to 8 characters.
Input	Optional	Output WSE Raster Prefix	GPString	Optional prefix to be used for naming the water surface elevation rasters. It should be limited to 8 characters. Note that WSE rasters will always be created as part of calculating ponded depth. Providing the prefix will save them otherwise they will be discarded after the ponded depth is calculated. They are not required for latter processing but can be useful for quality control.
