Exercise 6 - Raster Datasets; NHDPlusV2 contains many raster datasets. Delineating a Watershed The following procedure and example will help you locate and connect all of the high points around a watershed on a topographic map shown in Figure F-4 below. This site is an excerpt from Appendix E of the Method for the Comparative Evaluation of Nontidal Wetlands in New Hampshire, 1991. A watershed is an area of land containing common hydrologic features that eventually flow into a single larger body of water, such as a river, lake or ocean. The first thing is to load the project with the lesson data, which just contains a DEM. 18 0 obj <> endobj Determine the contour interval for the map. In this laboratory exercise techniques of map preparation will be presented. Until the end of the exercise, this form will be used. Figure 3 Shows The Location Along The Stream Where It Should Be Located. Topographic maps; for example, have a scale of 1:24,000 (which means that one inch measured on the map represents 24,000 inches (2000 feet) on the ground). A. Then ask them to repeat the exercise of outlining ... watershed delineation though, we need to understand how to read topographic maps. These tools rely on the datasets derived during terrain processing. 0000001477 00000 n 0000000656 00000 n ... generally can delineate a watershed from any point in less than 30 seconds. The purpose of this exercise is to illustrate watershed and stream network delineation based on digital elevation models using the Hydrology tools in ArcGIS and online services for Hydrology and Hydrologic data.
