  • November 8, 2009
  • Water Management Whittier Narrow dam in southern california is a dry project… most of the time. About 12 years ago, that vacant land looked pretty valuable to numerous developers. Suddenly, a swarm of applicants wanted to build auto malls, hospitals, thaetres, etc. in this highly desirable location.
  • Our dams are old. The age of the dams increases the importance of dam safety awareness.
  • This slide shows a schematic of a typical complex system Especially with backwater effects, upstream dams, and changing development patterns In 1997, El Nino brought warm storms onto an above-average snowpack We faced the prospect of 14 dam spills in the central valley over one infamous weekend during the El Nino driven flood season. Note where Sacramento sits and where Olivehurst sits What if…
  • Many rural communities along a 125 mile stretch suffered from levee breaches Could have been an urban area like Sacramento
  • Water Management (1): JOINT FLOOD CONTROL(RAIN FLOOD)/WATER SUPPLY = 475,000 ac ft JOINT FLOOD CONTROL (SNOWMELT)/WATER SUPPLY =1,000,000 ac ft [FEB 1 -&gt; AUG 1] (2)*: AVG. IRRIGATION DEMAND, FEB 1 -&gt; JUN 10 = 731,000 ac ft, JUN 10 -&gt; JUL 31=665,000 ac ft (3)*: CONTRACTED WATER USER: KING’S RIVER WATER ASSOCIATION (4)*: SPILLWAY CREST - 6 TAINTER GATES (5)*: TOP OF PARAPET WALL.
  • For our dams, there has been much planning done beforehand, and regulation plans were developed to account for many basin characteristics such as snowpack density , ground wetness, forecasted rainfalls and other human parameters, such as agricultural needs later in the year. These plans of how much water to release from the dam are codified in laws… but cannot account for every situation, so tough decisions are constantly being made.
  • 11/08/09 SPD/Bigornia System complexities… Upstream projects New urban development Levee adequacy? Maintenance, floodfight, ICW/RIP. inventory Rotenone white bass Water supply at our projects vs flood control in Tulare Lakebed USBR and State Water Project Deviations
  • This is important because we need to forecast how much water will be able to be conatined in our reservoirs’ flood pools. While operating the dams, many conflicting interests need to be prioritized, with residual risk in mind. In this diagram, we need to figure out how much water to release from the dam, and when to do it. These decisions might be made hourly, or even more often. In a typical operation scenario, we could have endangered species nesting at the edge of the reservoir, and downstream , there could be agricultural fields, a bridge crossing and homes, all potentially damaged at different water levels. How much water needs to be released to minimize damage… and when…
  • Another complex system is the Colorado River. Our dry Painted Rock Dam filled its 2.5 MAF capacity with a 200-yr event in 1993. We held water back to avoid overtopping levees and nearly ended up with a catastrophe on our hands.
  • After several weeks of spill, we examined the spillway, and found that we were a little lucky. We came about this close to spillway failure. Had the spillway eroded a few more feet, a couple of million acre feet would have rushed into the Colorado River at Yuma and into Mexico
  • Another complication is that vegetation is home to many threatened and endangered species, especially in our region with over 300 TES in California alone.
  • NEPA is thought of as the umbrella overseeing all other environmental compliance.
  • Your roles as project managers is not enviable, in that you have to juggle so many different goals, with such limited resources. The water control team at the division is working to help your team balance and juggle all these competing interests under the scrutiny of each of those competing interests. We’re proud to be a part of your team.
  • So after the recovery, it is once again time for us to evaluate what has happened, to apply any lessons learned into being better positioned and prepared for future flood events. The evaluation and preparation really brings us back to the beginning of the cycle the planning, which leads to designing and building…
  • Nadruk op wat de beslisser kan doen, welke info heeft hij nodig? Wij kijken daar naar over alle disciplines heen en integreren waar nodig.
  • **More than 350 miles of levees in the southeast Louisiana area **41 miles sustained severe damage **128 miles of levee sustained minor damage 5 Parishes 350 Miles of Levee/Floodwall 68 Pumping Stations (Fed &amp; Non-Fed) 4 Gated Outlets
  • November 8, 2009
  • Precipitation Hydrology and hydraulics Hurricane tracks, wind and surge Infrastructure response to loadings Levee integrity and system response Real-time floodplan flows Evacuation Special motel considerations Levee system interrelationships Risk analysis November 8, 2009
  • Towards a smart, networked flood control organization Improve quality of decision making during emergencies Better knowledge of crisis decision making and uncertainties Fast and real time prediction of calculated risks Education and training, scenario studies, design, O&amp;M Integration of Dutch flood control expertise and IBM IT knowledge November 8, 2009
  • Content is same as previous slide. Change background by changing Slide Color Scheme (Menu &gt; Format &gt; Slide Color Scheme...)
  • And we also work together on research. This is a plane that the NWS flies into El Nino storms to drop data-gathering electronics through the atmosphere and into the ocean to retrieve important meteorological and oceanographic information. We are very interested in other agencies’ improvements in forecasting technologies, as that will ultimately help our flood damage reduction mission.
