ABSTRACT
A computer model of hydrologic and water-quality
processes of the Irondequoit Creek basin
in Monroe and Ontario Counties, N.Y., was developed
during 2000-02 to enable water-resources
managers to simulate the effects of future development
and stormwater-detention basins on peak
flows and water quality of Irondequoit Creek and
its tributaries. The model was developed with the
program Hydrological Simulation Program-Fortran
(HSPF) such that proposed or hypothetical
land-use changes and instream stormwater-detention
basins could be simulated, and their effects
on peak flows and loads of total suspended solids,
total phosphorus, ammonia-plus-organic nitrogen,
and nitrate-plus-nitrite nitrogen could be analyzed,
through an interactive computer program
known as Generation and Analysis of Model Simulation
Scenarios for Watersheds (GenScn). This
report is a user's manual written to guide the
Irondequoit Creek Watershed Collaborative in (1)
the creation of land-use and flow-detention scenarios
for simulation by the HSPF model, and (2)
the use of GenScn to analyze the results of these
simulations. These analyses can, in turn, aid the
group in making basin-wide water-resources-management
decisions.
