  • The rainfall received by a small plot of tropical deciduous forest on sand dunes in Veracruz, Mexico, was partitioned into stemflow and throughfall components to determine wether funnelling by stemflow could reduce soil leaching by transmitting
  • FUNNELL, D. C.
  • Summer weekly rainfall data collected by approximately 120 untrained volunteers (mainly farmers) using unofficial gauges in McLean County, reveal unambiguous mesoscale patterns. All volunteers used the same clear plastic, funnel shaped gauge
  • rainfall at the central and southwestern belts, but there are strong rainfall anomalies due to the influence of topography and the funnelling of moist air flows. On a local scale, rainfall is not a limiting factor to soil erosion, and the zones of serious
  • Mima-like mounds in the Laramie Basin, are circular in plan view, lens- or funnel-shaped in cross-section, and frequently have relief of 15 to 65 cm. They consist of churned materials derived from adjacent/subjacent soils and sediments. This paper
  • The groundwater vortex hypothesis can account for the building of the mound higher at its center, the circular plan view and lens (or funnel) shape in cross-section, the inward spiral of sodium, the churned character of mound material
  • ). The datings of this artefact using 14C method indicate its connection with the activity of the Neolithic man, related to the Funnel Beaker Culture. The detailed analyses of the peat sediments (palynological and lithological) formed since the Atlantic phase
  • of mouths were recognized, each responding differently to river floods. In funnel topography mouths, flood morphology almost always displayed straight channels. In barrier-deflected mouths the response to floods is more complex.
  • distinctive behavior : barrier topography and funnel topography. It is concluded that the topographic setting of the beach is the primary influencing factor on the morphology of the mouths studied.
