Characteristics of the summer 1987 flow field in the Ionian Sea
Journal of Geophysical Research: Oceans, 1993 We present an extensive analysis of the first complete data set in the northern Ionian Sea collected during the Physical Oceanography of the Eastern Mediterranean (POEM) general circulation survey of September 1987. A four water mass structure of the basin is found to be represented by a first internal baroclinic Rossby radius of deformation of 11.8 km.

Characteristics of River Flows by Field Measurements
PROCEEDINGS OF HYDRAULIC ENGINEERING, 1991 The turbulent fluctuations of velocity have been measured actual rivers in the field where the relative water depth to roughness height is small, using ultrasonic flowmeter. The turbulent structures of river flows where roughness is relatively small, are similar to those in laboratory channels with the smooth bed.
