  19. 19. Land Use in SWAT Model• Developed a set of rules for establishing land use based on the NHD, NLCD, and NASS- CDL.• Trying to capture temporal changes (crop rotations) in one spatial layer. Have identified approximately 50 rotation patterns.• Having some problems identifying parcels with septic systems when a septic layer is not available.
  20. 20. Septics in Land Use Layer The septic rule: if the centroid of a parcel is not classified as water, wetland, or urban, put a septic at the centroid of the parcel. Using the Clermont County septic layer, we looked at how the rules performed. Note in the following figure that green parcels are those that are labeled on the county layer as having a septic, red dots are rule based septic locations. The rules are clearly overestimating septics. There are several reasons why the rules are overestimating, but these reasons are not easily addressed by changing the rules (for example, one house sits on two parcels). Also note that the right side of the map is Brown County.

  27. 27. Remote Sensing Pilot StudyPURPOSE.Demonstrate the use of remote sensing to estimate waterquality parameters in inland reservoirs and lakes toenhance Corps water quality management practices asdescribed in ERDC/EL TR-11-13 (Reif, 2011).
  28. 28. Draft SOW Prepared-Objectives 1) examine remote sensing imagery assets and analytical capabilities for interpreting water quality parameters in inland lakes and reservoirs 2) demonstrate and use the best available image types and interpretation techniques for a study area (i.e. Corps reservoir) in the Great Lakes and Ohio River Division  Examine and select a lake, reservoir or series of lakes/reservoirs in the LRD AO (e.g. Harsha Lake) representing a variety of environmental conditions, including water bodies with potential nutrient loading that may be vulnerable to Harmful Algal Blooms (HABs) and will provide an appropriate study site for development and demonstration of water quality interpretation using remote sensing  Should we consider adding a 2nd site – are there any lakes/reservoirs nearby to Harsha that may have different/worse water quality conditions?  Is Harsha big enough to be covered by MERIS?
  29. 29. CE-QUAL-W2 Modeling Update Submitted by Jeff last time, no new info. Inflow discrepancy issue unresolved
