Abstract:
Prediction of various ecological system variables or consequences (such 
as beach closings), as well as effective management of pollution at the 
watershed scale, require estimation of both point and non-point source 
material transport through a watershed by hydrological processes. The 
Great Lakes Environmental Research Laboratory and Western Michigan 
University are developing an integrated, spatially distributed, 
physically-based water quality model to evaluate both agricultural 
non-point source loadings from soil erosion, animal manure, and 
pesticides, and point source loadings at the watershed level. We have 
reviewed available water quality models and are augmenting an existing 
physically based integrated surface/subsurface hydrology model. It is a 
two-dimensional, spatially-distributed accounting of moisture in several 
layers (zones) for every “cell” (1 square kilometer) of a watershed. We 
previously modified the model to allow flow routing between adjacent 
cells surface zones, upper soil zones, lower soil zones, and groundwater 
zones. We applied it on a daily basis to several new Great Lakes 
watersheds this year. We are now expanding it by adding material 
transport capabilities to it to include movement of other materials 
besides water. We have demonstrated its material transport capabilities 
on the several watersheds. We are also modifying the model from a daily 
time step to an hourly. We are now gathering information on pollutants 
in Saginaw Bay watersheds to apply the model to simulate the movement of 
various materials into the bay, producing estimates useful to ecological 
system forecasters.

and would like to arrange transportation, please contact me.
