During the 1989/90 season a detailed feasibility study of the crop removal operation on Lewisham Section, CG Smith Sugar Limited, Sezela, indicated that the application of the split cut and stack 'flat land' method ofcrop removal offered important benefits. This paper discusses the problems associated with the traditional cut and stack system, and compares its performance with the newly impleme...

In this paper two-dimensional Direct Numerical Simulations (DNS) of dense clouds moving down steep slopes are presented for the first time. The results obtained are in good agreement with the overall characteristics – that is, the spatial growth rate and velocity variations – of clouds studied in the laboratory. Direct numerical simulations give, in addition to the overall flow structure, local...

Direct numerical simulation (DNS) is applied to investigate properties of katabatic and anabatic flows along thermally perturbed (in terms of surface buoyancy flux) sloping surfaces in the absence of rotation. Numerical experiments are conducted for homogeneous surface forcings over infinite planar slopes. The simulated flows are the turbulent analogs of the Prandtl (1942) one-dimensional lamin...

Abstract Ice aprons are defined as very small ice bodies covering steep rock slopes. They have only been the subject of increased scientific interest for a few years, despite fact that they condition mountaineering and obvious elements in high-alpine landscapes. However, little is known about their distribution, evolution physical characteristics. In this paper, we review existing knowledge on ...

Recent research on rill flows recognised that an 18% slope can be used to distinguish between ‘gentle’ and ‘steep’ cases for the detected differences in hydraulic (flow depth velocity) sediment transport variables capacity, actual load). The effects of flow velocity, friction factor capacity their interactions affect process-based erosion modelling. main aim this paper is investigate, first tim...

Partial loss and subsequent recovery of cochlear implant function in the first few weeks following cochlear implant surgery has been observed in previous studies using psychophysical detection thresholds. In the current study, we explored this putative manifestation of insertion trauma using objective functional measures: electrically-evoked compound action potential (ECAP) amplitude-growth fun...
