Hydraulic geometry of a small tidal estuary
Robert M. Myrick, Luna Bergere Leopold

A tidal channel in a marsh bordering the Potomac River near Alexandria, Va., was mapped, and current-meter measurements of discharge were made at various locations and at various stages in the tidal cycle. These measurements allowed analysis of the change of width, depth, and velocity with discharge at various cross...
Geology of the Three Forks quadrangle, Montana, with sections on petrography of igneous rocks
G. D. Robinson, Henry Frank Barnett
