Abstract The Jiangjia Gully (JJG), Yunnan Province, China, is one of several debris flow
gullies that characterize the topography of mountainous areas in China. Rainfall-triggered …

The Karakoram highway (KKH) is renowned for its complex natural environment and
geological conditions. The climate changes drastically and directly influences the frequency …

Rainfall in mountainous watershed presents high spatial variability due to elevation effects,
and this introduces uncertainty in forecasting hydrological hazards such as water floods and …

Debris flow is generally composed of a wide range of solid particles and viscous pore fluid. It
flows at a high velocity down a slope channel. Interactions between solid and fluid phases …

Debris flows often cause catastrophic damage to communities in the downstream area, by
direct impact and deposition. Theoretical predictions of impact pressure and volume of …

A new analytical model is proposed to estimate the peak impact pressure of debris flow
exerted on a rigid barrier. The new model consists of two terms, p= α 1 ρ 0 gh 0+ 0· 5 ρ 0 u …

Abstract Debris flows in Jiangjia Ravine in Yunnan province, China are not only triggered by
intense storms but also by short-duration and low-intensity rainfalls. This reflects the …

Extreme rainfall events in mountainous environments usually induce significant sediment
runoff or mass movements—debris flows, hyperconcentrated flows and stream flows—that …

A large number of paleo-landslide deposits exist in the Southeastern margin of the Qinghai–
Tibet Plateau. Once these deposits are destroyed, the disaster chain will cause huge …

Flow resistance against gravity‐driven forces is a key factor controlling debris‐flow mobility,
which is an important parameter for hazard risk assessment. In practice, Manning's formula …
