Mo-i-Rana - September 2002 Dam-break floods and sediment movement 1 IMPACT - WP4 Dam-break induced floods and sediment movement Slide 2 Mo-i-Rana - September 2002 Dam-break floods and sediment movement 2 Debris flow : research programme Experiments : acting forces (UDT) Uniform material Months 1-18 Graded material Months 18-32 BM UDT ? Slide 3 Mo-i-Rana - September 2002 Dam-break floods and sediment movement 3 Near-field dam break : programme Experiments: uniform material (UCL) Same bed levels Months 1-9 Initial step in bed levels Months 1-9 BM UCL 2 BM UCL 1 Slide 4 Mo-i-Rana - September 2002 Dam-break floods and sediment movement 4 Near-field dam break : programme Mathematical modelling (UCL) 1D model: months 1-6 2D-V model: months 21-32 BM UCL 3 Slide 5 Mo-i-Rana - September 2002 Dam-break floods and sediment movement 5 Near-field : research programme Validation of codes (UDT, UCL, Cem) Uniform debris flow (to be clarified) Months 11-12 BM UDT ?
