goal objectives
GOAL/OBJECTIVES
  • Preliminary study
  • Determine the available Public Domain Data
  • Determine the Suitability of the Public Domain Data
  • Review Existing Soil Erosion Model
  • Conduct a preliminary Soil Erosion Assessment for the Basin

CONCLUSION & FUTURE STUDY
  • Conclusion

-Limited Data in Public Domain

-Spatial Resolution of Available Data Inappropriate

  • Future Study

-Prepare proposal for grant

-Undertake a Preliminary Field Visit

-Select a Sub-watershed for Detailed Study
