Aerial Infrared Survey of the Walter F. George Lock and Dam, Chattahoochee River, Alabama-Georgia.
Abstract
A study was made to delineate subsurface seepage channels by infrared scanner imagery at the Walter F. George Lock and Dam, Chattahoochee River, Alabama-Georgia. Ground measurements of the conditions at the site were made to determine the optimum flight time for obtaining the infrared imagery and to aid in interpretation of the imagery. The infrared imagery was collected between 0300 and 0500 hr on 22 November 1969. The imagery was analyzed to determine if any trends existed which might suggest subsurface seepage channels at the site. The ground truth data were used in the imagery interpretation. Interpretation of the infrared imagery did not delineate any trends which indicated paths of flow of the groundwater and reservoir leakage. A study was then made to determine what features affected the tones on the infrared imagery. It was determined that surface features such as grass cover and soil moisture content produced most of the variations in the tone on the infrared imagery. Additional research is recommended in areas where seepage occurs closer to the terrain surface.
