Landscape evolution in the eastern Mojave Desert is recorded by sys1ematic changes in Pliocene to latest Pleistocene volcanic: land· forms that show discrete periods of eolian deposition, surface stabilization, drainage-network expansion, and erosion on basaltic lava nows. These processes are documented by K·Ar dating in conjunction with morphometric, sedimentologic. pedologic, and geophysica1 ...

The transfer of surface-generated meltwater to the subglacial drainage system through full ice thickness crevassing may lead to accelerated glacier velocities, with implications for ice motion under future climatic scenarios. Accurate predictions of where surface meltwater accesses the ice/bed interface are therefore needed in fully coupled hydrodynamic ice-sheet models. We present a spatially ...

Protein isolate is used in the food industry in order to process and stabilise food foams. Thereforethere has been a great deal of interest and research in order to understand the effect of processingparameters on the functional properties of the isolate. The major purpose of this research is to studythe foamability of the different proteins - starch nano-particle system. The results from exper...

Abstract: This paper discusses a new approach to estimate flow distribution over a continuous surface. This approach is based on the analysis of topographic form of a surface facet that dictates the flow distribution. In the case of a raster Digital Elevation Model (DEM), the facet consists of a centre cell and its eight neighbouring cells. If the form of the facet is convex, the water flow is ...

In these notes on drainage design procedure, three drain spacing formulae are considered suitable for designing sub-surface drainage systems. The Hooghoudt and the Kirkham-Toksoz formulae have been developed for steady state conditions and the Glover formula is applicable to the transient state condition. The steady state condition implies that the surface inflow is equal to the outflow through...

introduction: better use of water and soil resources in paddy fields, increase in rice production and farmer's income, installation of subsurface drainage system is necessary. the main goalof these systems, are aeration conditions improvement prevention of water logging, yield increase, land use increase and multiuse of the land. in different countries, installation of subsurface drainage cause...
