Physically-based modelling of shallow slides susceptibility at the basin scale ...

Data-driven methods are the most common approach for assessing shallow slides susceptibility. However, several studies have shown that physically-based models produce better results when incomplete landslide inventories are used. Despite this, physically-based modelling is seldom applied to large areas due to the difficulty in obtaining the required input data. In this study, conducted in the region north of Li...

Terraces of the Guadiana River between the Pulo do Lobo water fall and Pomarão ...

The terraces of the Guadiana River were mapped in the stretch between Pulo do Lobo and the Pomarão village. In this work we used the river terraces to estimate the uplift rate and to understand the main controls driving the river's incision throughout the late Pleistocene and Holocene. Four terrace levels were identified upstream of Pulo do Lobo and five terraces in the downstream reach. Uplift rates ranging be...

Debris flow in Indian Himalaya: a threat to emerging infrastructure

The present study aimed to understand the debris flow characteristics in view of frequent extreme rainfall events, expansion of road networks, tourist influx, and population pressure in the NW & Central Himalaya. Notably, majority of the human settlements, roads, bridges, buildings, and even protection measures in the NW & Central Himalaya do not take into consideration such debris flow impact scenario despite ...

Landslide susceptibility assessment using different rainfall event-based landsl...

The present work aims to evaluate potential sources of uncertainty associated with rainfalltriggered event-based landslide inventories within the framework of landslide susceptibility assessment. Therefore, this study addresses the following questions: (i) How representative is an event-based landslide inventory map of the total landslide activity and distribution in a study area?; (ii) How reliable is an event...

Post-fire debris flow hazard in the Zêzere glacial valley and Manteigas village...

A debris flow is a mixture of water and sediments that flows down channelized steep slopes, posing a potential hazard in mountainous regions due to high velocities (from very rapid to extremely rapid), high impact forces and extended run-out distances. The initiation of debris flows is generally attributed to the critical combination of three factors: steep slopes, unconsolidated sediments and water. Heavy rain...

Road Network Exposure to Deep-Seated and Shallow Slides at the Basin-Scale (Gra...

Landslides are well-known for their destructive capacity; however, risk only exists if an interaction with people, activities, structures and infrastructures occurs. When landslides affect roads and potential human losses, both road damage and road disruption can cause significant economic losses. Therefore, in the framework of spatial planning, civil protection, emergency and risk management and the evaluation...

Validation of 3-day rainfall forecast at the regional scale

Nearly half of the natural disasters in the world are due to hydro-geomorphological hazards. Therefore, rainfall forecast is a key parameter for the implementation of landslides and flash-floods early warning systems. In this work we developed a routine in R software that enables the validation of a 3-day rainfall forecast by comparison with the daily rainfall data recorded in 101 automatic meteorological stati...
