FOREWORD . The process outlined in this document includes steps for delineating watersheds in ESRI’s ArcGIS Desktop 10.2.2 software. Beginning at Rattlesnake Lake, the first 2-mile section to Rattlesnake Ledge Trail is one of the most popular hiking trails in the region. The general concept was introduced by [Digabel and Lantuejoul, 1978]. Water flows from the top of the saddle or ridge, down each side in the same way water flows down each side of a garden wall (See arrow on Figure E-2). Three types of watershed are distinguished according to size: Small size: < 250 km 2 A watershed is the upslope area that contributes flow—generally water—to a common outlet as concentrated drainage. A watershed is the area of reception of the rainfalls and of supplying the watercourse; the outlet flows depending thus on its surface. Watershed Delineation with ArcGIS 10.2.x Watersheds, also known as basins or catchments, are physically delineated by the area upstream from a specified outlet point. endstream endobj startxref For example, a long shape watershed generates, for the same rainfall, a lower outlet flow, as the concentration time is higher. (390-500-M, 4th Ed., Apr 2014) 500.A-2 . Smaller, local watersheds drain much smaller areas. <>>> (532-316)/6.6 = 216/6.6 = 32.73 m per km = 3.27%.
