Buffer Capability Indexes for Water Quality Planning in Missouri and Eastern U.S. Farmlands

Explore better buffer locations using sediment trapping efficiency data and interactions for effective water quality planning. Utilize Buffer Capability Index (BCI) maps for Missouri and the Eastern U.S. to assess sediment, groundwater, and dissolved pollutants.

  2. Missouri 1mi 0 Better Locations for Buffers?

  3. Missouri 1mi 0 Soil Survey

  4. Missouri 1mi 0 Sediment Trapping Efficiency STE (%) 10-25 25-50 50-75 75-100 Not Farmable Water

  5. Sediment Trapping Efficiency (%) STE = 100 – 85 e -1320 (SF) Sediment Factor = D50 / R K L S (104) Validation & Calibration Sediment

  6. Sediment STE = 100 – 85e -1320 (SF) Sediment Factor = D50 / R K L S (104) Dissolved Groundwater 1. Interaction – Hydric + Shallow WT 2. Interaction – Hydric + Deep WT 3. Interaction – Not Hydric + Shallow WT 4. No Interaction – Not Hydric + Deep WT WTE = 97 (IF) 0.26 Infiltration Factor = Ksat2 / R L S Three Functions

  8. BCI Maps: Upper Potomac Watershed, PA Sediment Dissolved Groundwater

  9. Chesapeake Bay Watershed Land Cover Sediment Groundwater Dissolved

  10. Sediment Eastern U.S. Farmlands Groundwater Dissolved

  11. Eastern U.S. Farmlands: Groundwater Percent Area 75-100 50-75 20-50 0-25 Not Farmable Water

  12. Eastern U.S. Farmlands: Sediment STE 10-25 25-50 50-75 75-100 Not Farmable Water
