Hydrologic calculations were performed. <br />using HEGMMS to generate inflow'hydrographe at various points of interest fpr use <br />In the subsequent hydrauft modeling. The hydraulic ijnobta� consisted of modeling <br />I <br />storm drains, culverts, Stone Carryon creek, and its tributary using XP-SWmM. Storm <br />drains, culverts, and the main Channel of Stone Canyon Creek and Its tributary were <br />analyzed under unsteady, One-dim0rililonid flow assumptions. Shallow flow regulthig <br />from Culvert and storm drain overflow and Stone Canyon Creek overbonk flow were <br />modeled In tWo-dimenslorts. <br />CaMON116 Center Hydrologia/Hydraulles Study I Calffornia Conservation <br />Corps <br />Project engineer who assisted In performing hydrologic and hydraulic analyses to <br />evaluate various flood Control mitigation alternatives for the exioung.ladlitles at the <br />California Conservation Corps' (CCC) Camarillo Center In Venture County, California. <br />In March 2011, the Nmarillo Center experienced a rain event that generated <br />approximately 5-6 inches of precipitation. The offsite drainage conditions created <br />stgnifloont flooding Issues as off-site drainage ditches looked adequate capacity for <br />this large event. The hydrologic and hydraulic portions of the study evaluated various <br />storm events, Including the 100-year, 24-hour storm. <br />25E-484 <br />
