Sapping Features of the Colorado Plateau: a Comparative Planetary Geology Field Guide [PDF]

open access: yes
This book is an attempt to determine geomorphic criteria to be used to distinguish between channels formed predominantly by sapping and seepage erosion and those formed principally by surface runoff processes.

Loen Rockfall Center

open access: yes, 2021
Seven percent of the Norwegian landscape consists of rock and bare mountains, this makes a total of thirteen thousand mountains. The Norwegian culture is strongly influenced by settlements close to the wild mountain landscape. These populations vary from small villages to larger cities. Living close to these natural forces has resulted in many villages

Field trip guide to Oligocene Limestones and Caves in the Waitomo District [PDF]

open access: yes, 2013
The field guide runs from Hamilton to Waitomo to Te Anga and return in limestone-dominated country developed in transgressive sedimentary deposits of the Oligocene Te Kuiti Group – a world class example of a temperate shelf carbonate depositional system.

Shape Effect of Rockfall Impacting Sandy Soil Cushion Layer–Reinforced Concrete Slab Composite Structure

open access: yesMedžiagotyra
The impact effects of falling rocks on sand–reinforced concrete slab composite protective structures involve several factors. Among them, the existing codes are unable to consider the effect of rockfall shape and the angle of contact between the rockfall

Effect of rockfall fragmentation on exposure and subsequent risk analysis [PDF]

open access: yes, 2018
Rockfalls are frequent natural processes in mountain regions with the potential to produce damage. The quantitative risk analysis (QRA) is an approach increasingly used to assess risk and evaluate the performance of mitigation measures.
