11Water Quality Forecasting
- Regression models
- Forecast water quality parameters using as input
season, discharge, temperature, precipitation - Operational (short term, present climate and land
use) - Transport models
- Forecast water quality parameters using a
detailed survey of pollutant sources in the
watershed and mass/energy transport equations - Operation and planning (long term, different
climate and land use scenarios)

19 Calibrations ? Hourly for 5 more watersheds ?
Daily for 12 Erie watersheds Surveys ? 12 5
watersheds for manure, fertilizer,
pesticides ? Build GIS layers of DLBRM RUSLE2
parameters for 5 watersheds ? Gather analyze
in-stream water quality data for 8 5
watersheds Transport ? Estimate
annual/seasonal averages build discharge
relations sediment in 6 target watersheds,
nutrient microbes in 7, and in-stream
temperature in 7 (including Saginaw) ? Add
transport to DLBRM sub-calibrate Resource
Sheds ? Develop for 11 Erie watersheds ?
Develop for other materials for 8 watersheds
Forecasting ? Link 7 watersheds to lake
circulation models ? Maybe assess climate change
scenario nutrient/microbe impacts
