Document Summary

Pros: flood damage would have been greater without levees. Perhaps: remove some levees to restore wetland habitat and ease flood risk: move towns, provide disaster relief funds only for moving to higher grounds or raise floor level of existing houses, flood frequency curves. Flood frequency curves are used by fema (federal emergency management. Agency) to issue recommendations in disaster management and prevention. The physical reasoning behind this statistical number: since the recurrence time is only an average time, the time to the next flood of the same size could be slightly shorter or longer. Therefore, there is a chance that a 100-year flood does not occur within the next 100 years but a little later. Case studies (test material!: case 1: the case san diego. San diego adopted the l. a. style channel system: most runoff channels are lined with concrete, even the bottom.
