Physical Template:

“The physical template of watershed structure is ultimately determined by varying combinations of climatic, geomorphic, and hydrologic processes. As a result of different combinations of these formative processes, different types of watersheds are created. Below are some examples that show how different from one another watersheds of different origin and physical template conditions can be.” (US EPA Watershed Academy website: http://www.epa.gov/watertrain/ecology/ecology5.html)
 
“Valley Type II:
moderately steep, gentle sloping side slopes often in colluvial valleys.”		 “Valley Type VI:
moderately steep, fault controlled valleys.”		 “Valley Type VIII:
wide, gentle valley slope with well developed floodplain adjacent to river terraces.”
NONPOINT SOURCE POLLUTION or “NPS”:
Nonpoint source pollution is the pollution of ground and surface water that results from the variety of ways that humans use the land. Unlike pollution from factories and sewage treatment plants ("point sources"), NPS comes from many diffuse widespread sources. Soil particles, fertilizers, animal manure, pesticides, oil, roadsalt, fecal material from failing septic systems, pet waste, and debris from paved areas are transported over the landscape by storm runoff, snow melt, and wind. Eventually entering streams, wetlands and lakes, or penetrating into ground water, these pollutants damage aquatic habitat, harm aquatic life, and reduce the capacity of water resources to be used for drinking water and recreation. Because NPS doesn't come out of a pipe that's easily located, it has to be managed differently than facilities with site-specific permits. That's why so many of the measures directed at controlling NPS are voluntary, and why so many people need to be involved.” (Indiana Watershed Planning Guide, p. 3)
