Point Source (PS) and non-Point Source (NPS) loading
- PS loads relatively constant (b<ə, concentration strongly subject to dilution)
- NPS loads usually increases with increasing runoff: b ~ 1
can standardize loading by area: Yield = weight/time/ unit drainage area
recapitulate: three ways to look at dissolved materials:
- concentration [mg/liter]
- load or loading [mg/sec or g/day or kg/yr]
- yield [e.g. mg/sec/sq mile or g/day/acre or kg/yr/km2]
