Critical Depth in Trapezoidal Channels

Journal of the Hydraulics Division, 1962
Several methods of computing critical depth in trapezoidal channels are described; various equations are expressed in terms of suitable nondimensional parameters in order to make them universal in application.

Critical depth and marine primary production

Proceedings of the Royal Society of London. Series B: Biological Sciences, 1991
The concept of critical depth, as formulated by Sverdrup ( J. Cim. perm. int. Explor. Mer. 18, 287 (1953)) to explain the onset of the spring bloom of phytoplankton, is discussed. Simplifying assumptions (use of a linear photosynthesis-light curve, use of daily averaged irradiance), adopted by Sverdrup in his computation of the growth term, are ...

Depth Hermeneutics and Critical Human Geography

Environment and Planning D: Society and Space, 1990
Initially, the author draws on the debate between Habermas and Gadamer about the methodology of the social sciences. Although there are substantial differences in their positions, together they form the basis for elaborationg a depth hermeneutics which deploys the opposing attitudes of explanation and understanding into a comprehensive interpretive ...

Critical Depth, Velocity Profiles, and Averaging

Journal of Irrigation and Drainage Engineering, 1993
Open-channel hydraulics is a subset of shallow-water theory that, in turn, is a subset of hydrodynamics. The distinguishing feature of shallow-water theory is the assumption of hydrostatic pressure. One-dimensional, open-channel hydraulics goes further in that it averages the velocity in both the vertical and the horizontal directions.

Comparison of In Depth and Critical Few Models

Infotech@Aerospace, 2005
As an alternative approach, the author proposes a simple high -level spreadsheet model of the critical few items. This technique allows a team to quickly assess the system level of effectiveness. It is a somewhat more qualitative model focused on the few items that impact operational status and how redundancy or backups improve functionality.

ISCP: In-depth model for selecting critical security controls

Computers & Security, 2018
Abstract The primary goal of all organizations worldwide is to reduce potential threats and vulnerabilities. An information security control assessment is a far-reaching way to deal with control analysis that can help organizations to measure the adequacy and effectiveness of their present and planned security controls.

Resonant sloshing near a critical depth

Journal of Fluid Mechanics, 1994
Oscillations of a tank at a near-resonant frequency have been shown to produce a response which changes from a ‘hard-spring’ to a ‘soft-spring’ response as the depth passes through a critical value. This paper investigates the transition region and it is shown, using a symbolic manipulator, that in fact the large-amplitude response is that of a soft ...

Critical and Normal Depths in Semielliptical Channels

Journal of Irrigation and Drainage Engineering, 2015
AbstractNormal and critical epths are important parameters in the design, operation, and maintenance of open channels. Semielliptical, prefabricated channels are widely used as tertiary canals in irrigation networks. In semielliptical channels, the governing equations are highly nonlinear in the normal and critical flow depths; thus, the solution of ...
