Physical Vulnerability Assessment of Hood River County County

As one might expect, the highly vulnerable areas in Hood River

County are generally located in the more rugged western half of

the region, relatively far from civilization and infrastructure. As

a resident of the area, I know that these high risk regions are sparsely populated and mostly used seasonally for recreation

purposes. Thus, it may be an important goal for future analysis to address means of alerting and evacuating these isolated

regions in case of natural disaster occurrence.

Physical Vulnerability

The Pacific Northwest is renowned for its rugged beauty,

serrated landscape, and prodigious rainfall. As a resident of Hood River, Oregon, I am lucky enough to be exposed to such

breathtaking scenic variation on a day to day basis. On the other hand, can being able to look out your kitchen window and

see three different volcanoes really be considered lucky? In the 1980 eruption of Mount St. Helens, 57 people were killed, not to

mention thousands of animals. Hundreds of square miles were

absolutely devastated, resulting in over a billion dollars worth of damage. In addition to volcanism, there are other natural dis-

asters to worry about in my geographical region, such as land-slides, earthquakes, and floods, oh my! Given the tentatively

precarious nature of living in such an area, the purpose of this

project is to assess the levels of physical vulnerability through-out Hood River County. This project will demonstrate the use of

GIS as a risk analysis tool in evaluating a region’s susceptibility to environmental disaster.

Proximity to Rivers

A physical vulnerability assessment was conducted for Hood River

County. Five vulnerability criteria were chosen for the evaluation.

These criteria were deemed important in terms of their influence

on the County’s level of risk exposure. For each criteria, a 1-3 ranking scale was developed, with 1 = low, 2 = moderate, and

3 = high vulnerability. The criteria’s geospatial dataset was then reclassified using this ranking system, and a map was generated

for each individual vulnerability factor. The five datasets were

then weighted equally in order to create an overall physical vulnerability map for the County.
