Flood Summary Chehalis River Basin, January 1990 Event (and November 1990 EventAddendum)

摘要

The purpose of this report is to document Chehalis River flood data for the floodof 8-12 January 1990. Although high water and flooding occurred in other basins, the scope of this report has been limited to the Chehalis River basin. An addendum is provided to briefly discuss some observations of the flood that occurred in November 1990. This flood report is organized under five primary categories: meteorology, hydrology, flood damage estimates, river forecasts, and flood fighting. The meteorology portion covers the atmospheric characteristics of the storm as it passed over the basin, while hydrology covers the characteristics of the runoff across the basin and into the rivers. The section on damage estimates reports observations of flood-caused damages by region and category. Economic data are based upon field observations.
