Vertical profiles of aeolian sand mass flux

Vertical profiles of aeolian sand mass flux
Vertical profiles of the horizontal mass flux of blown sand are investigated experimentally using a passive vertical array in a wind tunnel. This investigation is complemented by the measurements of the longitudinal profiles of mass flux using
a horizontal sand trap. The experiments were conducted with 2 test sands and 5 different stream velocities. A simple equation applicable for both the vertical and the longitudinal sand mass flux variations is introduced and the parameters are estimated from

Regularities of mountain geosystems

The main features of the mountains are considered and relation with the vertical zonality of temperature and precipitations are observed. Taking into account the mesoclimatic belts in mountain valleys, the diversity of vertical belts and the slope
assymetry in various climatic zones are discussed. Reconstruction of changes of vertical zones in European mountains during the Pleistocene and early Holocene is proposed. - (DG)

Vertical distance, releif energy and altitudinal limits as distinguishing features of high mountains

Vertical distance, releif energy and altitudinal limits as distinguishing features of high mountains
Mountain constitute the Earth's third pole, because they hypsometrically repeat the climate zones as far as the Arctic within smallest space. For this reason, the vertical distance and relief energy are characteristic and distinguishing features

Modeling daily soil water dynamics during vertical drainage using the incoming flow concept

Modeling daily soil water dynamics during vertical drainage using the incoming flow concept
The aim of this study was to develop a quasi-analytic model to calculate the daily soil water dynamics during vertical drainage with reasonable accuracy for diverse soils, i.e., light, medium and heavy soils using the incoming flow concept. Three
models for the simulation of vertical drainage in soils are compared : RMSD, SRVDM and Hydrus-1D. They are tested using data of a Eutric Regosol in Bekkevoort, Belgium and a sandy soil in Georgia, U.S.
