The resulting debris flow travels down the feeder channel and onto the surface of the fan. [21] Debris flow fans have a network of mostly inactive distributary channels in the upper fan that gives way to mid- to lower-level lobes. The channels tend to be filled by subsequent cohesive debris flows.
A debris flow in Ladakh, triggered by storms in 2010. It has poor sorting and levees. Steep source catchment is visible in background. Debris-flow deposits are readily recognizable in the field. They make up significant percentages of many alluvial fans and debris cones along steep mountain fronts.
The debris fan dams a lake, Haidersee, which is now used as a source of irrigation water through a system of channels, and nearly all the heath is now cultivated and prosperous. The fan also displaces the main river, Adige, and the large tributary, Puni, to opposite sides of the valley. Disastrous floods still occur, destroying houses and even ...
A debris cone is commonly made when rock from a high-up narrow slit or gorge falls into a flat-floored valley. Here the soil and loose materials are deposited, leaving a mound of conical shape. While an alluvial fan is formed when flowing water rushes rock and soil down a slope, debris cones come from one of several dry processes known as mass ...
Instead, the debris flows overwhelmed the channel and the flows overtopped the banks wherever the channel changed direction. Once free of the culvert, the channel rapidly avulsed across the fan and spread debris throughout the community. These overbank flows demolished 2-story houses and destroyed the first two stories of apartment buildings.
Mississippi has been fined $75,000 after the game with LSU was interrupted by fans throwing debris on the field. The SEC announced the fine Thursday, adding to the $100,000 penalty that had ...
Fans throwing debris onto the field hurt the university's reputation. I was unabashedly embarrassed when I read about the hooligan yahoos and their deplorable actions at DKR Memorial Stadium ...
Debris fan colluvium refers to the aggregates of gravity-driven and fluvial deposits located near the hillslope's base or the eroded catchment area. [1] It appears shell-like from the vertical view and is cut by the flowing rivers. [1] In certain parts of the debris fan, there may be some woody plants covering the land surface. [1]
