Single-channel seismic-reflection profiles and sidescan-sonar records collected on Georges Bank
David C. Twichell
1981, Open-File Report 81-438
Subbottom seismic-reflection, echo-sounding, and sidescan-sonar records were collected by the U.S. Geological Survey during two cruises over Georges Bank aboard the R/V OCEANUS (cruise 056, March 6-15, 1979 and cruise 067, August 6-13, 1979) (fig. 1). The data collected during these two cruises contributed to a study of bed-form types...

A model for simulation of flow in singular and interconnected channels
Raymond W. Schaffranek, R.A. Baltzer, D.E. Goldberg
1981, Techniques of Water-Resources Investigations 07-C3
A one-dimensional numerical model is presented for simulating the unsteady flow in singular riverine or estuarine reaches and in networks of reaches composed of interconnected channels. The model is both general and flexible in that it can be used to simulate a wide range of flow conditions for various channel...
