A range of seismic images likely to be encountered from stream-cut channels is examined with ray tracing computer modeling. The channel shapes, sizes, depths of burial, and associated geologies are examined to determine their effect on seismic images, waveforms, and ultimate interpretation. The study uses channel geometries taken from the Pulaski, Bush City, Moberly, and Nesvacilka channels which are assumed to he at various depths of burial. Results show that seismic sections often do not approximate geologic cross sections, that seemingly random reflections have geologic meaning, and that channels can be detected by their effects on the amplitude and shape of lower reflectors. The resolution of channels is summarized in tables of resolvability.Ball State UniversityMuncie, IN 47306
