Debris flow is a disaster that frequently occurs in mountainous regions worldwide due to climate change and human activities can lead serious economic losses casualties [...]

Debris-flow activity is expected to change in a future climate. In this study we connect susceptibility model for debris-flows on regional scale with climate projections until 2100. We use assess changes of hydro-meteorological trigger conditions debris flows six regions the Austrian Alps. find limited an annual basis, but distinct when separating between types and regions. While east south Aus...

OBJECTIVES MicroCT allows the complex canal network of teeth to be mapped but does not readily distinguish between structural tissue (dentine) and the debris generated during cleaning. The aim was to introduce a validated approach for identifying debris following routine instrumentation and disinfection. METHODS The mesial canals of 12 mandibular molars were instrumented, and irrigated with E...

[1] Ring-mold craters (RMCs), concentric crater forms shaped like a truncated torus and named for their similarity to the cooking implement, are abundant in lobate debris aprons (LDA) and lineated valley fill (LVF) in the northern mid-latitudes on Mars, but are not seen in surrounding terrain. LDA and LVF have been interpreted to form by flow of debris, but uncertainty remains concerning the me...

[1] The sculpture of valleys by flowing water is widely recognized, and simplified models of incision by this process (e.g., the stream power law) are the basis for most recent landscape evolution models. Under steady state conditions a stream power law predicts that channel slope varies as an inverse power law of drainage area. Using both contour maps and laser altimetry, we find that this inv...

Debris flow surges can terminate in a steep channel of > 15°. However, the termination process and mechanisms remain unknown. This study conducted small-scale flume experiments to investigate effects local sediment accumulation on debris-flow channel. The demonstrated that bed terminates debris surge owing abrupt changes gradients infiltration interstitial water. Subsequently, mass terminate...

A catastrophic storm that struck the central Virginia Blue Ridge Mountains in June 1995 delivered over 775 mm (30.5 in) of rain in 16 h. The deluge triggered more than 1000 slope failures; and stream channels and debris fans were deeply incised, exposing the stratigraphy of earlier mass movement and fluvial deposits. The synthesis of data obtained from detailed pollen studies and 39 radiometric...
