their presence can imply the nature of the coast in areas where they form. Estuarine 

 meanders can also indicate the relative importance of fluvial and marine processes. 

 Advantages of radar imagery in terrain studies are discussed.

 Determining Changes in Coastlines," Technical Report RSC-16, Remote Sensing Center,

Report describes a study of coastal changes at San Luis Pass on Galveston Island, Texas, 

 from photos and coastal charts. Vertical and obUque photos and charts were compared to 

 determine changes in the tidal inlet and adjacent beach. The report notes while color photos 

 are easier to interpret, they are not necessary for coastal change studies. Several photos 

 show the San Luis Pass area and data on changes are presented. Report concludes that 

 photos are an adequate sensor for detecting changes due to such long term phenomena as 

 coastal processes or such short term events as storms.

Report describes a study of pulp mill effluent dispersion from photos. Three sites along the 

 Oregon and CaMfornia coasts were investigated. Black and white, black and white infrared, 

 and color or color infrared photos were used. Water current velocity and direction, waste 

 concentrations, toxicity zones, and diffusion coefficients were determined from the photos. 

 Photo density measurements determined waste plume characteristics. A computer program 

 was developed to process the data and plot results of the analysis. Surface water current was 

 the most important variable in shaping the effluent plume. Results of the data are compared 

 with field samplings from a boat.

Article discusses requirements for color and satellite photos in oceanograpliic appUcations. 

 The need to select proper techniques to record subsurface features is noted. Sensitivity of 

 emulsion layers of color films and light attenuation characteristics of water are discussed. 

 The authors show that the blue-sensitive emulsion layer should not be eliminated for best 

 results with either aircraft or sateUite photos. Most of the article is a discussion of image 

 enhancement by sUcing techniques to map shallow areas and sediment flows on sateUite 

 photos.
