Measurements of hillslope debris flow impact pressure on obstacles
Abstract We present measurements of hillslope debris flow impact pressures on small obstacles. Two impact sensors have been installed in a real-scale experimental site where 50 $ m^{3} $ of water-saturated soil material are released from rest. Impact velocities vary between 2 and 13 m/s; flow height...

| 520 | |a Abstract We present measurements of hillslope debris flow impact pressures on small obstacles. Two impact sensors have been installed in a real-scale experimental site where 50 $ m^{3} $ of water-saturated soil material are released from rest. Impact velocities vary between 2 and 13 m/s; flow heights between 0.3 and 1.0 m. The maximum impact pressures measured over 15 events represent between 2 and 50 times the equivalent static pressures. The measurements reveal that quadratic velocity-dependent formulas can be used to estimate impact pressures. Impact coefficients C are constant from front to tail and range between 0.4 < C < 0.8 according to the individual events. The pressure fluctuations to depend on the sensor size and are between 20% and 60% of the mean pressure values. Our results suggest that hazard guidelines for hillslope debris flows should be based on quadratic velocity-dependent formulas. | ||

Two impact sensors have been installed in a real-scale experimental site where 50 $ m^{3} $ of water-saturated soil material are released from rest. Impact velocities vary between 2 and 13 m/s; flow heights between 0.3 and 1.0 m. The maximum impact pressures measured over 15 events represent between 2 and 50 times the equivalent static pressures. The measurements reveal that quadratic velocity-dependent formulas can be used to estimate impact pressures. Impact coefficients C are constant from front to tail and range between 0.4 < C < 0.8 according to the individual events. The pressure fluctuations to depend on the sensor size and are between 20% and 60% of the mean pressure values.

Two impact sensors have been installed in a real-scale experimental site where 50 $ m^{3} $ of water-saturated soil material are released from rest. Impact velocities vary between 2 and 13 m/s; flow heights between 0.3 and 1.0 m. The maximum impact pressures measured over 15 events represent between 2 and 50 times the equivalent static pressures. The measurements reveal that quadratic velocity-dependent formulas can be used to estimate impact pressures. Impact coefficients C are constant from front to tail and range between 0.4 < C < 0.8 according to the individual events. The pressure fluctuations to depend on the sensor size and are between 20% and 60% of the mean pressure values. Our results suggest that hazard guidelines for hillslope debris flows should be based on quadratic velocity-dependent formulas.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Hillslope debris flow</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Field scale tests</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Impact pressure</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Impact coefficient</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">McArdell, Brian W.</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Bartelt, Perry</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Wendeler, Corinna</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Landslides</subfield><subfield code="d">Berlin : Springer, 2004</subfield><subfield code="g">9(2011), 2 vom: 10.

Measurements of hillslope debris flow impact pressure on obstacles |
| abstract |
Abstract We present measurements of hillslope debris flow impact pressures on small obstacles. Two impact sensors have been installed in a real-scale experimental site where 50 $ m^{3} $ of water-saturated soil material are released from rest. Impact velocities vary between 2 and 13 m/s; flow heights between 0.3 and 1.0 m. The maximum impact pressures measured over 15 events represent between 2 and 50 times the equivalent static pressures. The measurements reveal that quadratic velocity-dependent formulas can be used to estimate impact pressures. Impact coefficients C are constant from front to tail and range between 0.4 < C < 0.8 according to the individual events. The pressure fluctuations to depend on the sensor size and are between 20% and 60% of the mean pressure values. Our results suggest that hazard guidelines for hillslope debris flows should be based on quadratic velocity-dependent formulas. |
