The design of avalanche protection dams. Recent practical and theoretical developments
Johannesson, Tomas; Gauer, Peter; Lied, Karstein; Barbolini, Massimiliano; Domaas, Ulrik; Faug, Thierry; Hakonardottir, Kristin Martha; Harbitz, Carl Bonnevie; Issler, Dieter; Naaim, Florence; Naaim, Mohamed; Rammer, Lambert (Lecture, 2008)Recent experimental and theoretical studies of the flow of avalanches against obstructions have been used, in combination with traditional design guidelines, to formulate recommendations for the design of dams and other ... -
On pulsed Doppler radar measurements of avalanches and their implication to avalanche dynamics.
Gauer, Peter; Kern, Martin; Kristensen, Krister; Lied, Karstein; Rammer, Lambert; Schreiber, Helmut (Journal article, 2007)Pulsed Doppler radar measurements from several avalanche releases are analyzed to gain an in-depth understanding of avalanche dynamics. A pulsed Doppler radar emits short pulses and samples the echo in distinct time ... -
Radar measurements of snow avalanche full scale experiment in Ryggfonn.
Rammer, Lambert; Kristensen, Krister; Lied, Karstein (NGI Publication;203, Chapter, 1998)At the full scale experiment site of NG! in Ryggfonn, avalanche velocities and forces have been measured through 15 years. In April 1997 an Austrian developed INW pulsed Doppler radar was used to measure avalanche velocities ...
