What is a USGS Huc?
A hierarchical hydrologic unit code (HUC) consisting of 2 additional digits for each level in the hydrologic unit system is used to identify any hydrologic area (see Federal Standards and Procedures for the National Watershed Boundary Dataset, 4th ed.
What is Huc scale?
Each hydrologic unit is identified by a unique hydrologic unit code (HUC) consisting of two to eight digits based on the four levels of classification in the hydrologic unit system.
What does Huc 12 mean?
HUC12: USGS Watershed Boundary Dataset of Subwatersheds. The Watershed Boundary Dataset (WBD) is a comprehensive aggregated collection of hydrologic unit (HU) data consistent with the national criteria for delineation and resolution.
What is a Huc 10 watershed?
HUC – 10 WATERSHED Typically from 40 to 250 K Acres (62 to 390 mi²) Work continues per new Interagency Guidelines presented to Federal Geographic Date Committee on December 2000. (Was formerly called HUC-11). Called 5th Level or Watershed 5th Level.
What is an 8-digit HUC?
Hydrologic Unit Code: Each hydrologic unit is. identified by a unique hydrologic unit code (HUC) consisting of two to twelve digits based on the six. levels of classification: 8-digit HUC (Cataloguing Unit)
What are Huc 12 watersheds?
HUC 12 watershed means a hydrological unit code consisting of a sequence of 12 numbers identifying a hydrological feature like a river, river reach, or lake or an area like a drainage basin. HUC 12 watershed means and refers to a United States Geological Survey (“USGS”) 12-Digit Hydrologic Unit Code Watershed.
What does Huc 10 mean?
The number of digits in the code indicates the scale of the hydrologic unit. A ten-digit hydrologic unit (HUC10) is a bit smaller than a county, a twelve-digit hydrologic unit (HUC12) is a bit smaller than a township. Add digits to specify a smaller watershed within a larger river basin.
What is an 8 digit HUC?
What does Huc 8 stand for?
What is a Huc zone?
Hydrologic units are given a Hydrologic Unit Code (HUC). A hydrologic unit is a drainage area delineated to nest in a multi-level, hierarchical drainage system.
What is a 5th Field watershed?
Fifth-field watersheds have become the standard size used for research and projects by a variety of agencies and organizations. Therefore, it is convenient for fifth-field watershed to be the unit usually referred to herein by the term “watershed.” The Umpqua Basin has 33 fifth-field watersheds.
What is Huc 8 watershed?
HUC 8 maps the subbasin level, analogous to medium-sized river basins (about 2200 nationwide, pictured in red in the image); and HUC 12 is a more local sub-watershed level that captures tributary systems (about 90,000 nationwide used by EnviroAtlas to display national metrics for the conterminous U.S.).
