Past use of the JALBTCX <br />toolbox has revealed repeated steps that <br />have been combined to minimize user <br />interface. The toolbox has been updated <br />to read past data and incorporate <br />additional datasets that expand the <br />change analysis to more than two <br />datasets. <br />The Coastal Resilience Index (CRI) has <br />been developed to quantify the resiliency <br />of beach and dune systems. CRI was <br />developed to leverage the significant <br />amount of beach profile data that USACE <br />collect when designing, installing, and <br />monitoring Coastal Storm Risk <br />Management (CSRM) projects. CRI relies <br />on morphology metrics derived from the <br />feature extraction tools in order to <br />quantify the protective qualities of a <br />coastal system. The index compares the <br />quantification of protective qualities <br />(beach height, beach width, beach <br />density) with disturbance factors (wave <br />height, storm surge, wave runup) to allow <br />for comparison of a beach's resiliency <br />alongshore and to other beach <br />environments. <br /> <br />Elevation change in New Hampshire.
