Sohlenbelüftung gegen Kavitationserosion in Schussrinnen
(1984)WasserWirtschaftUrsache und Auswirkung der Kavitations-Erosion in Schussrinnen werden dargestellt. Sohlenbelüfter werden als Schutzmassnahme vorgestellt und ein neues Bild des Fliessverhaltens gegeben. Auf Hinweise für die Praxis wird ein weiteres Schwergewicht gelegt. Ungelöste Fragen physikalischer Natur werden erwähnt.Journal Article -

Trübeströme in Seen: Sauerstoffeintrag durch grundnah eingeschichtetes Flusswasser
(1984)Schweizerische Zeitschrift für HydrologieNear-bottom current measurements in the main delta areas of the Walensee (Switzerland) and of Lake Constance yielded evidence that sporadic high influxes of clastic suspensions caused by flood stage discharges of tributaries generate turbidity underflows. Turbid suspensions plunge down the delta front as hyperpycnal inflows with speeds up to 130cm/s. These periodic intrusions of well oxygenated river water may influence the oxygen budget ...Journal Article -

Electrical resistivity soundings of glacier beds: A test study on Grubengletscher, Wallis, Swiss Alps
(1984)Journal of GlaciologyElectrical resistivity sounding, using electrodes which are lowered directly to the ice–rock interface in bore holes, is proposed as a technique for studying the exact position of glacier beds, as well as their lithological characteristics. A test study is described on Grubengletscher, a partially cold Alpine glacier in Switzerland. Results of soundings along a 400m long profile indicate that previous depth determinations, based on radio ...Journal Article -
On pseudo-uniform flow in open channel hydraulics
(1984)Acta MechanicaThe differential equation that governs the longitudinal variation of the surface profileh(x) in steady plane channel flow is qualitatively discussed for the case of pseudo-uniform flow states. The solutions are either of the cnoidal or solitary wave type. It is shown that, among all cnoidal waves, solitary waves have minimum energy head. Further, surface profiles mustbreak whenever the Froude-number exceeds the value2–√ (which is close ...Journal Article
