    <descript>
      <abstract>During 2018 to 2021, Oregon Department of Geology and Mineral Industries developed channel migration zone maps for major rivers within Benton, Marion, Morrow, and Washington County. This polygon represents the 100-year erosion hazard area (EHA_100). The EHA_100 includes the areas at risk from lateral migration and channel widening during the next 100 years based on historical erosion rates.</abstract>
      <purpose>This dataset was created to increase awareness of natural hazards, to be used within risk assessments, and to be used to identify, prioritize, and implement hazard mitigation actions.</purpose>

        <horizpar>DOGAMI digitized this feature class at a scale of 1:4,000, or higher resolution. Future conditions and changes in hydrology, sediment supply, land use, riparian vegetation, and human modifications to the river and watershed may result in migration beyond the mapped EHA. As a result, monitoring channel migration and remapping all CMZ components every 30 years or more frequently is recommended.</horizpar>

      <procstep>
        <procdesc>The process we used to develop the EHA was divided into three broad steps: 1) measuring the historical erosion rate, 2) projecting the erosion rate 100-years into the future and buffering the historical migration area by this projected distance, and 3) removing areas from the EHA that extend beyond the modern valley bottom. For the river segments that did not have measurable migration during the period of observation, we used an erosion rate established by previous studies. Our EHA methodology was designed to include the maximum possible extent of lateral erosion for a river segment based on the observed historical erosion patterns. Please review the accompanying report for more details. This layer was generated using Esri ArcGIS v. 10.7.</procdesc>
