Dynamic Systems Biology Modeling and
Simulation (2015) – Answers to Exercises –
DiStefano
Prediction equations - answers-Runoff, sediment yield, potential evapotranspiration, pathogen
transport
How GIS based watershed scale model works - answers-Data collection, develop model, run
model
How watershed scale model works - answers-Delineate watershed, divides the watershed area
into several small watersheds, divides sub-watersheds into HRU, can simulate scenarios on HRU
Model simulation benefits - answers-Provides a forecast of planned actions on water quality,
water quality monitoring is slow and does not account for future conditions, allows rapid
assessment of alternative scenarios, linkage between pollutant sources and water body, GIS
interfaces greatly simplify the modeling process
Model simulation limitations - answers-Sensitivity / uncertainty, calibration, validation,
inadequate representation of BMP
What model simulation can tell us - answers-What, why, where, who, when, how, watershed
planning
Best management practices - answers-Structural, vegetative, management
Watershed - answers-The area of land where all of the water that is under it or drains off of it
