Hydroseek Measurements - Nitrogen

Hydroseek Measurements Unfiltered Residues
-
Future WorkAdd lead, zinc, and phosphorus measurements to the mapSediment and pollutant accumulation farthest downstreamMake concentration grid based on the run-off in each catchmentExercise from 2005Compare actual measurements to acceptable thresholds
