  3. Environmental Engineering • Slide Show http://www.sos.state.ne.us/business/regsearch/Rules/Environmental_Quality_Dept_of/Title-198/Appendix-A.pdf

  4. Runoff settling basin and holding pond • Manure is scraped periodically from feedlots and spread on croplands • Good management practices decrease risk of contaminating water supplies http://www.ces.purdue.edu/extmedia/WQ/WQ-7.html

  5. Proper Storage of Liquid waste • Can be used as a viable fertilizer • Reduces chance of surface and ground water contamination • Meets regulations http://www.state.sd.us/denr/DES/Ground/AWMS/AWMS.htm

  6. Pen USDA Research Project Effects of Pond Ash as a Feedlot Pen Surface and Animal Stress-Level on the Prevalence, Levels, and … • Project Number: 5438-32000-026-03 • Project Type: Trust • Start Date: May 01, 2006 • End Date: Apr 30, 2008 • http://www.ars.usda.gov/research/projects/projects.htm?ACCN_NO=410515

  7. Table of Runoff Curve Numbers (SCS, 1986) • http://www.lmnoeng.com/Hydrology/hydrology.htm

  8. Calculating Rainwater peak Runoff Rational Method • The formula is: Q=CiA • Q = peak runoff rate (cfs) • I = is rainfall intensity (in/hr) • A = drainage area (acres) • C is runoff coefficient (Activity 4.5.3A) http://webmail.nicolet.k12.wi.us/~Jason_Huber/FOV2-00014049/FOV2-00019020/FOV2-0001903C/Rainwater%20Runoff.pdf?FCItemID=S008265FE

  9. Water run off in the community • http://edweb.sdsu.edu/sciencetg/elementary/pond/pond4.html (Area of Pavement & Buildings) ____________________________  X 100% = % of rain lost to run off (Area of entire playground)

  10. Heavy Rains Drench G.I. • Heavy rains drench G.I. • Rainfall early Sunday brought 5.07 inches of water • Grand Island had flooded: • parking lots • streets • low-lying areas

  11. Maxed out G.I. rain detention cell • Foreground is Lawrence Lane • Behind is maxed out rain detention cell • Far back is spillage on to State Street in front of McDonalds occurred http://www.flickr.com/photos/candleshoe/941130784/

  13. Calculating Storm Water Run-on @ Construction Sites • Run-on • water that comes from off-site locations • drains onto construction site Q - run-on flow (m3 /sec) C - run-off coefficient for drainage area (%) i - rainfall intensity (mm/hour) A - area draining onto the site (km2 ) http://www.dot.ca.gov/hq/env/stormwater/publicat/const/Dec_2000.pdf
