| Authors:
J. J. DeVries; HYDROLOGIC ENGINEERING CENTER DAVIS CA
|
| When land development encroachments into river flood plains are permitted, the magnitude of the flood peak discharge will be increased due to removal of flood plain storage. When the flood plain encroachment is limited (for example, when no more than one foot of water surface rise is permitted), the study results indicate that the increase in the flood peak is usually relatively small; it is generally less than 10 percent. ... |
