Research ArticleOpen accessEvery word in the titleDeep Erosion by Continental Ice Sheets: A Northern Missouri River Drainage Basin Perspective: North AmericaEric ClausenWhile accepting some erosion by continental ice sheets most geologists reject a previously proposed deep erosion by continental ice sheets hypothesis, yet common sense logic suggests continental ice sheets should have eroded much more than they are usually given credit for. Such situations arise in scientific communities when an accepted paradigm cannot adequately explain significant observable evidence. A new and … …Current Research in Geoscience, Vol. 8, Issue 1 · 18 Jan 2019 · 8,883 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsEffect of Covers and Rainfall on Soil and Water Conservation Using a Tilting Flume ModelS. Compliew, L. Suwanchai, N. KrongwiengThe effect of stone and vegetative covers was evaluated for soil and water conservation in a waterway on salty soils in the Northeast of Thailand. Experiments were conducted on a hydraulic tilting flume under simulated unit flow (120 and 45 cm2s-1), rainfall (120 mm/hr) and slope (0, 1.2,1.4,1.6,1.8,2.0, 2.2, 2.4, 2.6, 2.8 and 3.0%) conditions. The depth of soil was … …American Journal of Applied Sciences, Vol. 4, Issue 6 · 30 Jun 2007 · 6,629 accessesView PDF Cite

InvestigationOpen accessIn the abstractChanges in the Composition and Properties of Meadow Solonchaks of the Ili Alatau Foothill Plain in the Republic of Kazakhstan during a Long Postmeliorative PeriodZhainagul Yertayeva, Saginbay Kaldybaev, Aigul Kaiyrbekovna BeketovaThe optimal depth of the groundwater table and the water-salt regime is of importance in the postmeliorative period. The scope of these studies is to provide scientifically grounded assessment of previously reclaimed soils (water irrigation with a total norm of 5000 m3/ha under conditions of deep horizontal drainage, 1986-1989) in the postmeliorative period of 2015-2016 and to develop parameters for … …OnLine Journal of Biological Sciences, Vol. 17, Issue 4 · 14 Oct 2017 · 7,265 accessesView PDF Cite
