Some properties of the geometric mean and its use in water quality standards
La moyenne géométrique est fréquemment utilisée pour faire des comptages de bacilles pour des normes de qualité de l'eau. Son espérance est une fonction de la taille de l'échantillon| elle est très sensible au biais de la fonction de distribution

Construction of nomograms for the determination of geometric distortions. Derivations of an approximation technique for the elimination of geometric distortions. (HL).
Geometrische Verzerrungen in kosmischen photographischen Aufnahmen. (Geometric distortions in photographic space images)
Study of the effect of the Earth's curvature, terrain relief, Earth's rotation, proper motion and atmospheric refraction on geometric distortions in photographic space images. (HL).

Samples of sediment collected from the Severn floodplain between Worcester and Gloucester following the severe flooding in January and February 1990, were analysed for their grain size distribution. Geometrical and hydraulic data relating
Multiscaling in the environment manifests itself in self-similarity of spatial geometrical structure and the spectrum of the fractal dimensions of matte masses or relevant geophysical parameters. The real importance of scaling power law dependence
approach and models illustrate in an elementary way how size and mass distribution can be multiscaling and (mono)scaling in the environment to describe fault structures, linear elements of relief, vegetation in city, sea-ice, soil moisture are presented.

The purpose of this paper is to report a field-based investigation on the geometric structure of step-pools in the Santa Monica Mountain streams. The step-pool morphology is evaluated empirically in light of variations in a downstream direction
In connection with the large number and regular shape of drumlins within particular fields, many students have used morphometric and geometric methods in order to find similarities in the features and in the spatial distribution of forms
The spatial economy is analyzed in the general equilibrium framework by considering the production and the utility functions depending on spatial distribution and sets. The geometric constraint between the location and the extension of goods
A mathematical model of image-ground relationship based on the collinearity equations for central projection in photogrammetry, satellite orientation elements and scanner geometry of the multispectral scanner of Landsat is developed to geometrically
rectify the MSS image. It is found that when applied to the 1: 1,000,000 scale image a residual error of 1 pixel can be achieved if 9 or more evenly distributed ground control points are used. A computer program for this mathematical model has been
of the geometrical characteristics and grain size distribution with taluses of the same rock type formed by regular blocks, remarkable differences are found, especially concerning the slope angle and the size distribution of blocks as a function of the distance from

Geometric and kinematic attributes as well as spatial distribution of fault-related fractures from carbonate rocks of the Southern Gargano have been sampled and analysed. The analysis allowed to recognise two main types of fault-related brittle

Field investigations of natural levees were conducted in the developing avulsion belt of the lower Saskatchewan River. One goal of the study was to examine geometric characteristics and the variations in shape of levees. Another goal was to examine
the surficial grain-size distributions of levee deposits to determine lateral variations from the channel margin to the floodbasin. The relationships between the topography and lateral grain-size variations were then assessed in the context of the development
Geometric characteristics and evolution of a tidal channel network in experimental setting
of their width, depth and length. The nature of the observed exponential distributions within creek attributes (width, depth, length) allows for statistical predictability of relative creek attribute dimensions downstream and through time.
