Have you ever driven over a road after heavy rain and wondered why it\u00a0wasn\u2019t\u00a0flooded? Underneath that road,\u00a0there\u2019s\u00a0likely a\u00a0culvert, a pipe or channel moving water from one side to the other. Culverts are everywhere, and they\u2019re critical to how water actually moves across a landscape.<\/span><\/p>\n

But\u00a0here\u2019s\u00a0the\u00a0challenge: in the digital elevation models (DEMs)\u00a0use<\/span>d<\/span>\u00a0for hydrologic analysis, culverts are invisible.\u00a0Roads\u00a0data appear\u00a0as\u00a0solid ridges\u00a0in the data, and water has no way to pass beneath them. This\u00a0gap produces real errors in how we derive stream networks and model flow paths.<\/span>\u00a0<\/span><\/p>\n

In\u00a0ArcGIS\u00a0Pro<\/span>\u00a0<\/span>3.7, we introduced two\u00a0new tools\u00a0\u2013 Generate Breach Lines<\/strong><\/a> tool and Adjust Raster to Stream<\/a><\/strong> tool- specifically\u00a0designed to account for culverts in high-resolution\u00a0DEMs\u00a0and\u00a0complete\u00a0the workflow that\u00a0the\u00a0<\/span>Locate Depressions<\/span><\/b><\/a>\u00a0tool\u00a0started in 3.6.<\/span><\/p>\n

    \n
  1. Locate\u00a0potential culvert sites.<\/span><\/li>\n
  2. Define how water moves through them.<\/span><\/li>\n
  3. Update your surface raster accordingly.<\/span><\/li>\n<\/ol>\n

    The Scenario: Something Looks Off<\/span><\/span>
    <\/span><\/h2>\n

    Im<\/span>agine\u00a0<\/span>you\u2019re<\/span>\u00a0working with high-resolution elevation data to generate a stream<\/span>\u00a0network<\/span>. You run\u00a0<\/span>a\u00a0<\/span>stream<\/span>\u00a0extraction\u00a0<\/span>analysis<\/span>\u00a0<\/span>and review the output<\/span>.
