Presentation Transcript

  1. Basic reach structures: arcs<vsec_subuit<vsec2<vsec1 {use master_channels cover} Special sets: vsec subunits { defined for lower river below Croton only} vsec* {Mixed set of vsec, vsec2, and subunits output by hydro model} Nhd_arcs vsec2 (1.1 ) vsec1 (1.1)

  2. Basic areal data structures: grids (40m) < nhd_arc sheds<vsec(1and 2) sheds< sub-basins< hec _basin sheds Special sets: 319 sub-basins Nhd_arcs vsec sub-basins HEC_basins

  3. MREMS sub-basins 319 HUCs

  4. Characteristic scales for MREMS database Important note: all smaller units can be summarized (directly or indirectly) at Musk sub basin level

  5. Ranking sub basin responsesusing MREMS output Done by MREMS out variable… Inherent sensitivity… rank(std[ D mean sub-basin response {scen.D-scen.N} / D landcover pc1]) degree of future threat… rank(std[scen.D / scen.C] for values or rank(std[scen.D - scen.C]for ratios responsiveness (%change) to land management scenario rank(std[scen D –scen N]/ Scen D]

  6. sub-basin average “inherent sensitivity” to LU change 1rst quartile 2nd quartile 3rd quartile 4rth quartile [TP] [TIN] Channel Erosion Sediment Load Q

  7. land management “responsiveness” Biological Integrity Erosion Tot Phosphate

  8. Channel Erosion responses to land use Change Inherent sensitivity, degree of future threat, responsiveness to scenarios Muskegon River sub-basins by quartile (darker = higher)

  9. [Total P] responses to Land Use Inherent sensitivity, degree of future threat, responsiveness to alternate scenarios Muskegon River sub-basins by quartile (darker = higher)

  10. Sub basin Prioritization Analysis • Parameter specific priority: balancing risk and responsiveness • Rank by parameter:( std risk * std responsiveness)

  11. Sub basin Prioritization Analysis • Overall Ecological triage: • Average of TP, Erosion Potential, Bio Integrity ranks
