1 Virginia Tech Department of Civil and Environmental Engineering CEE 5734 – Urban Hydrology and Stormwater Management Homework #10: Calibrating Streamflow in SWMM Due: April 13, 2011 This homework exercise builds on last week’s assignment. The emphasis now turns away from mechanics of modeling continuous streamflow and towards the calibration process. Additional, we introduce the evaporation as a new physical process being modeled. Students will work as individuals or in groups* of two with an emphasis on optimizing parameters to match observed streamflow. Tasks: 1. We continue to focus on USGS 02055100 TINKER CREEK NEAR DALEVILLE, VA for water-year 2008 (October 1, 2008 – September 30, 2009). Use the NCDC website to obtain: a. Accounting for spin-up behavior, re-download precipitation data for Roanoke International Airport (Coop ID: 447285) before the onset of the calibration time period (suggest 1 year in advance of October 1, 2008). b. Monthly evaporation data for all available monitoring stations in Virginia. 2. Refresh the rainfall file that SWMM uses so that model spin-up takes place before the period to be calibrated begins. Be sure to revise the “Simulation Options: Dates” entries to initiate simulations in advance of October 1, 2008, but to only
