متن کاملComment on the paper : “ Basin hydrologic response relations to distributed physiographic descriptors and climate ” by Karen Plaut
A basic problem relating to the long-term water balance involves splitting precipitation P, into runoff R, and actual evapotranspiration E. Berger and Entekhabi (2001) showed that the evapotranspiration efficiency E/Ep (Ep denotes potential evapotranspiration) and the runoff ratio R/P, are related to physiographic basin features and regional climate information. Berger and Entekhabi (2001) esti...

متن کاملFuzzy Classification of Physiographic Features Extracted from Multiscale DEMs
Geomorphological landforms are generally viewed as Boolean objects. However, recent studies have shown that landforms are more suitable to be viewed as fuzzy objects, whereby a landform is defined as a region in the continuum of variation of the surface of the earth. In this paper, the fuzzy classification of physiographic features extracted from multiscale DEMs is performed. First, the lifting...
متن کاملNickel Sulfide versus Laterite : the Hard Sustainability Challenge Remains
There are widespread nickel resources around the world, but divided principally between nickel sulfide or laterite (oxide) resources. Historically production has been dominated by sulfide ores but future production is increasing shifting to laterite ores. The principal reason for this historically is that sulfide ores are easier to process, through conventional mining, smelting and refining, co...
