Froude for Thought

The Froude number is a hydraulic parameter often used to relate aquatic habitats and biotopes to flow intensity. Independently of some trenchant critiques (see, e.g., Clifford et al. 2006), there seems to be no inherent hydrological, geomorphological, or ecological reason that the Froude number (Fr) should be the best indicator of habitat or ecological niches.

Fr is a dimensionless number that describes flow regimes in open channels and is unquestionably useful in many aspects of hydrology, geomorphology, and engineering. It is the ratio of inertial and gravitational forces:

Fr = V/(g d)0.5

Fr < 1 indicates subcritical or tranquil, and Fr > 1 supercritical or rapid flow. But variations in Fr within the subcritical range (where it typically falls) can be significantly related to, e.g., geomorphic units and habitats within channels.

Handbook for Preliminary Dissertation Fieldwork: A Practical Guide for the International Student Researcher

With support from a Susan Abbott-Jamieson Award, Kevin Talbert spent Summer, 2013, conducting preliminary fieldwork in Tanzania.  This practicum report is designed to be a handbook for any Anthropology graduate students conducting field research abroad, but It will be of interest to graduate students and other researchers conducting field research, especially internationally, for the first time.  The presentation covers such topics as entering the field, locating an appropriate field site, seeking local institutional affiliations, the research permit process, etc.  This roundtable is designed to be useful for anyone seeking to embark on first fieldwork, not just in Africa but elsewhere as well.  It focuses especially on the preliminary fieldwork stage in preparation for a longer, PhD fieldwork length immersion later.
