The effect of sediment density parameter values on the debris flow velocity parameters

Debris flow is a phenomenon where the material from eruption carried away by of water due to rain in upstream area river and usually crashes into watersheds around volcano. The potential for large debris flows can be caused high rainfall sediment deposits that occur during flows. Rainfall affect volume velocity A simulation was out anticipate casualties damage using SIMLAR V2.1 modifying intensity density flow. Based on result, we obtain results velocity, volume, affected values obtained testing with 162 mm 1370 kg/m3, 2340 kg/m 3 , 2635 2820 respectively, were 2.72 m/s, 2.16 2.50 2.57 m/s. same are 186,381 m 311,116 274,030 294,987 . test results, it concluded significantly affects Where inversely proportional higher density, slower while directly density. sediment, volume.
