dc.descriptionLandscape change detection using Landsat ETM+ sensor data and image processing methods based on band orthogonalization are used for initial mapping of flood inundation along JackrabbitWash, in Maricopa County. Results indicate that image processing of Landsat data, which has a nominal 30 m pixel size spatial resolution, can provide a direct method to document flooding in remote areas of Arizona. This study analyzes a portion of two Landsat scenes covering part of Maricopa County, west of Phoenix, Arizona. The study finds that Jackrabbit Wash, in contrast to many of the adjacent streams, has a spectral signature that indicates there was detectable landscape modification associated with the October, 2000 flood. The area of flooding is clearly indicated on the processed satellite image as a band of yellow. Field validation consisting of checking several reaches of Jackrabbit Wash around Vulture Mine Road, corroborated the evidence from the satellite change image. Ubiquitous evidence for very significant flooding was found. The performance of the change detection on a regional basis appears strong. On the local basis, not every pixel which showed evidence for inundation in the field, was highlighted as changed on the change image. A significant finding is that the flooding affected the upstream portions of Jackrabbit Wash and therefore must be related to storm precipitation in the headwaters area.
