  • (processus vertical). Dans la zone bretonne, le réseau s'est établi rapidement car les immigrants étaient déjà chrétiens et les diocèses n'étaient pas structurés (processus horizontal).
  • Vertikale Profile des Windvektors und des Turbulenzkoeffizienten in einer (quasistationären) planetarischen Grenzschicht mit freier Inversion. (Vertical profiles of the wind vector and the turbulence coefficient in a (quasi-stationary) planetary

  • Vertical profiles of the wind vector and the turbulent coefficient (eddy viscosity) are discussed. Further empirically determined (observed) vertical profiles (especially of the turbulent coefficient) are compared with corresponding vertical

  • , through an understanding of the developmental history of coastal dunes, it may be possible to relate multiple episodes of dune development to conditions associated with vertical displacements of the coastal zone.
  • 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
  • Maps of vertical crustal movements in the conterminous United States over the last ten million years.
  • Map A: Data sources for vertical movements| Map B: Neotectonics, rates and magnitudes of vertical movements| Map C: Rates and relative magnitudes of post-glacial vertical movements, these three maps compiled showing sources of data available

  • 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)
  • Wading measurements of vertical velocity profiles
  • rod and a table and an analytical expression to more easily obtain vertical velocity profiles in rivers.
  • 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
  • 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.
  • Karst subzone division in vertical cycle zone and its significance
  • as well as limestone strata , and the vertical cycle zone ascertained by predecessors can be divided into 3 subzones. Deep karst morphology near groundwater level under vertical cycle zone develops better in the middle and late periods of karst process.
  • On vertical zonation of the Northwestern Yunnan.
  • Vertical zonation of the area transition between the Qinghai-Xizang plateau and the Yunnan-Guizhou plateau is based primarily on vegetation cover and soil, modified by considerations of temperature and moisture variations. The regional
  • differentiation of the vertical zonation displays a transition from east to west and from south to north corresponding to temperature and moisture distribution. (TNC).
  • Vertical accretion rates in fluvial systems : a comparison of volumetric and depth-based estimates
  • This study compares depth- and volume-based estimates of sediment accumulation for well-dated vertical accretion sequences at Broomhaugh Island in the Tyne basin, northern England. High resolution dating control (based on heavy metal stratigraphy
  • and cartography) coupled with detailed reconstruction of channel geometry allows accumulation rates to be calculated for the last 300-400 years. The results show a marked disparity in the magnitude and pattern of vertical accretion rates between the 2 approaches.
