Hydrologic Units

2-digit= 1st level = 22 regions

4-digit= 2nd level = 222 subregions

6-digit= 3rd level = 789 accounting

8-digit= 4th level = 2223 cataloging

new!

10-digit= 5th level = ~22,000 watersheds

12-digit= 6th level = ~160,000 subwatersheds

GOAL: Initial “draft” completed

December 2002

Project

Status

karst in kentucky fifty five percent of the state has potential for karst
Karst in Kentucky:Fifty-five percent of the statehas potential for karst.

Areas shown in red have high potential for karst

Areas shown in green have moderate potential for karst

Areas shown in blue have limited potential for karst

slide8

Areas of Shallow Soluble Bedrock in the

Conterminous States

20 percent of the area of the 48 states is underlain by karst.

vision

WBD, a “key” part . . .

Vision:

Follow a drop of water from where it falls on the land, to the stream, and all the way to the ocean.

issues to be resolved
Issues to be resolved
  • Coastline – can watersheds be independent of coastline?
  • Estuarine systems – no clear hydrologic controls of flow.
  • Deltaic coastlines – streams do not converge to a point.
  • Barrier Islands – are they their own hydrologic unit or defined by area of influence?
  • Island Groups – (e.g. FL Keys, Pacific Islands, Aleutian, Tongas Nat. Forest)
noaa nos implementation
NOAA/NOS Implementation
  • Pilots
  • Coastal delineation guidance
  • state/coast implementation
    • Assisting state groups
        • Workshops
        • Data and data manipulation
        • One-on-one with States
