Grand River Watershed (Lake Michigan)
Built maps of observable watershed
characteristics elevation, slope, roughness,
soil texture, land cover, upper/lower soil
zone water capacity, thickness, permeability
later, nonpoint pollution surveys

Calibrate define spatial variation of model
parameters use observable watershed
characteristics search for spatial mean
parameter values minimize RMSE of model

Water 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)

GLERLs Short-term Deterministic Outflow Forecast
uses
  • Distributed Large Basin Runoff Model (DLBRM)
  • Observed meteorology for period prior to forecast
  • Initial moisture storage conditions for DLBRM
  • Forecast meteorology from NWS for forecast period
  • Streamflow gauge data from USGS
  • Materials transport models

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
