Choosing Watersheds/HUC10 to perform modeling on transport of contaminants and possible detailed monitoring of potenal spills or background Han, Y., Simon, C., Arjmand, S., Abad, J. D. + ShaleNetwork team Permi=ed Wells Drilled Wells Three Type Violaons 3 Types Violaon: (1) erosion / sedimentaon, (2) polluDon incident, (3) pit & impoundment issues. Permi=ed minus Drilled (P-D) 5% Shortest Time/HUC10 (Han et al, in preparaon) Gauge Staons Stream Use (based on total length of streams) Procedure to obtain crical watersheds • Now, we have the following layers: – 1. Permi=ed wells / HUC10 15% – 2. Drilled wells / HUC10 15% – 3. Three type violaons / HUC10 14% – 4. Permi=ed minus drilled 14% – 5. USGS gauge staons 14% – 6. Stream Use (excepDonal value stream/high quality water…) 14% – 7. 5% shortest Dme / HUC10 14% • Reclassify each layer based on what we concerned, for example, Permi=ed wells reclassified by “count”, Stream use reclassified by “sum_length” • Give a WEIGHT to each layer Weighted Overlay HUC10 Name Permied Drilled 5% 3 Permit Gauge Stream Shortest Violaon Minus Stao Use Time Drilled n South fork Tenmile (South) criDcal criDcal criDcal criDcal criDcal Tioga River criDcal criDcal criDcal criDcal criDcal criDcal Lycomming Creek criDcal criDcal criDcal criDcal criDcal Sugar Creek criDcal criDcal criDcal criDcal criDcal Upper Monogahela River (South) criDcal criDcal criDcal Lower Branch Susquehanna River criDcal Lower Susquehanna River criDcal criDcal criDcal criDcal Tenmile Creek (South) criDcal criDcal criDcal criDcal Upper Pine Creek criDcal criDcal criDcal Lower Pine Creek criDcal criDcal Babb Creek criDcal criDcal Larrys Creek criDcal criDcal Towanda Creek criDcal criDcal criDcal criDcal Lower Loyalsock Creek criDcal Wyalusing Creek criDcal criDcal criDcal Meshoppen Creek criDcal criDcal criDcal criDcal Tunkhanock Creek criDcal criDcal criDcal CriDcal HUC10 watersheds PotenDal HUC10 Watersheds HUC10 Name Permie Drilled 5% 3 Type Permit Gauge Stream d (Count/ Shortes Violao Minus Staon Use (Sum (Count/ HUC10) t Time n Drilled (Count/ Length/ HUC10) (Count/ (Count/ (Count/ HUC10) HUC10) HUC10) HUC10) HUC10) Tioga River 481 300 42 115 181 25 53.776 Lycomming Creek 426 254 18 69 172 8 200.046 Sugar Creek 688 340 76 146 348 6 0 South fork Tenmile 657 359 77 35 298 37 5.484 Upper 397 293 117 76 104 40 0 Monongahela River Our SuggesDons are: 1. To choose two watersheds, one in the south west and another one in the north east. 2. for the SW, we can choose South fork Tenmile à near Pi=sburgh 3. for the NE, we can choose either Tioga, Lycomming or Sugar creek Any thoughts for the NE? .
