A description of a two-phase approach, using photos and wave refraction techniques, to 

 survey beach erosion along 330 miles of North Carohna coast. Advantages of the photo 

 approach to beach erosion are discussed. The procedure is the measurements between stable 

 reference points, the dune line and high water Une on comparative photos in different years. 

 Difference in ground distances obtained by multiplying photo measurements by the photo 

 scale represents the change in location of the dune Une and high water Une. Annual rates of 

 change are computed by dividing the total changes by the elapsed time interval. A summary 

 of the erosion data is presented.

Report describes a study of water quality in estuaries from multispectral photos. Five 

 advantages of remote sensing for water pollution studies are Usted. A multispectral camera 

 system of four conventional 35-mm cameras fastened to a frame was developed for the 

 research program. The characteristics and capabiUties of the system are described. The study 

 areas were along the west side of Narragansett Bay and at Point Judith Pond. The potential 

 of four film types, conventional panchromatic, black and white infrared, color, and color 

 infrared, was investigated. Results of using the photos for detection and evaluation of 

 estuarine pollution sources are described. The technique to detect small and large pollution 

 sources was important. The color and color infrared films gave the best results. A brief 

 review of related studies is included.

 Columbia 



The use of radar imagery to examine estuarine meanders in Eastern Panama and 

 Northwestern Columbia is described. The basic characteristics and modes of operation of 

 radar imagery are covered. Radar imagery depicts drainage features very clearly, and is 

 exceUent for investigating the characteristics of estuarine meanders and other coastal 

 drainage features. Estuarine meanders develop under certain environmental conditions and
