Marine-terminating glaciers may experience seasonal and short-term flow variations, which can impact rates of ice flux through the glacier terminus. We explore the relationship between variability in the flow of a large tidewater glacier (Belcher Glacier, Nunavut, Canada), the seasonal cycle of surface meltwater production and the rapid drainage of supraglacial lakes. We demonstrate a novel met...
Abstract For single-lip drills with small diameters, the cutting fluid is supplied through a kidney-shaped cooling channel inside tool. In addition to reducing friction, also important for dissipation of heat at edge and chip removal. However, in previous investigations drills, it was observed that remains on back side edge, accordingly, insufficiently cooled. this paper, simulation-based inves...
Side weirs as flow diversion devices are widely used in irrigation, land drainage and urban sewage systems. In the present study, the effects of the length and height of inclined side weir crest on discharge coefficient were investigated in prismatic and nonprismatic rectangular channels.. In this study, 675 laboratory tests were conducted. Analysis of experimental tests showed that the disch...

BACKGROUND Drainage is a routine practice used to reduce hematoma and blood loss following total hip arthroplasty. The aim of this study was to assess the effect of clamped drainage on blood loss and wound healing after total hip arthroplasty. METHODS A prospective cohort of 44 patients with hip osteoarthritis or femur head necrosis undergoing total hip arthroplasty was randomized equally int...
The sustainability of irrigated agriculture in India is threatened by waterlogging, soil salinity, and alkalinity. To reverse declining agricultural productivity, a combination of surface and subsurface drainage, supplemented by improved irrigation management, has been identi®ed as the most appropriate strategy. But subsurface drainage for salinity control is costly. Therefore, its bene®ts in t...
networks on surface runoff from agricultural catchments Levavasseur F., Bailly J.S., Lagacherie P., Colin F., Rabotin M. a UMR 1221 LISAH F-34035, INRA, Montpellier, France. b UMR 1221 LISAH F-34035, AgroParisTech, Montpellier, France. c UMR TETIS F-34093, AgroParisTech, Montpellier, France. d UMR 1221 LISAH F-34035, Montpellier SupAgro, Montpellier, France. Abstract The study of runoff is a cr...
Side weirs are flow diversion devices that are widely used in irrigation, drainage and urban sewage systems. The present study focuses on the investigation of the effect of oblique side weirs on the discharge coefficient of a side weir under subcritical flow condition in rectangular channels. In this study 106 laboratory tests were conducted and the results were analyzed to find out the influen...
Modeling landscape with high-resolution digital elevation data (DEM) in a geographic information system can provide essential morphological and structural information for modeling surface processes such as geomorphologic process and water systems. This paper introduces several DEM-based spatial analysis processes applied to characterize spatial distribution and interactions of ground and surfac...
Thermally incised meltwater channels that flow each summer across melt-prone surfaces of the Greenland ice sheet have received little direct study. We use high-resolution WorldView-1/2 satellite mapping and in situ measurements to characterize supraglacial water storage, drainage pattern, and discharge across 6,812 km(2) of southwest Greenland in July 2012, after a record melt event. Efficient ...
