If the Arc Hydro Tools menu does not appear in the list, click on “Customize” (Scroll down the list to see “Customize”). Right click on the menu bar to pop up the context menu showing available tools as shown below.Ĭheck the Arc Hydro Tools menu. Create a new empty map, and save it as Exercise.mxd (or any other name – Ex3 is the name used in this tutorial).
Inside NHD.mdb, you will be interested in NHDFlowline and NHDPoint feature classes stored in Hydrography feature dataset. Data.zip contains a data folder with the raw DEM named smdem_raw (from the NED – National Elevation Dataset of the United States), and a geodatabase named NHD.mdb (National Hydrography Dataset).
The data files used in the exercise consist of DEM grid for the San Marcos Basin in Texas and the hydrography data. Main Steps Exploring the DEM … Developing Terrain Preprocessing:ĭEM Reconditioning Fill Sinks Flow Direction Flow Accumulation Stream Definition Stream Segmentation Catchment Grid Delineation Catchment Polygon Processing Drainage Line Processing Drainage Density EvaluationĪrcHYDRO / Watershed and Stream Network DelineationĪvailable Data The data are provided in the accompanying zip file, Data.zip. The utility of the Arc Hydro tools is demonstrated by applying them to develop attributes that are useful for hydrologic modeling. Raster analysis is performed to generate data on flow direction, flow accumulation, stream definition, stream segmentation, and watershed delineation. The Arc Hydro tools are used to derive several data sets that collectively describe the drainage patterns of the catchment. You will perform drainage analysis on a terrain model for the San Marcos Basin. Goals of the Exercise The purpose of this exercise is to illustrate, step-by-step, how to use the major functionalities available in the Arc Hydro tools for Raster Analysis.
