Effects of geological structures on rainfall‐runoff responses in headwater catchments in a sedimentary rock mountain

open access: yesHydrological Processes, 2020
Clarifying rainfall‐runoff responses in mountainous areas is essential for disaster prediction as well as water resource management. Although runoff is considered to be significantly affected by topography, some previous studies have reported that ...

Modelling of the Dynamic Young’s Modulus of a Sedimentary Rock Subjected to Nonstationary Loading

open access: yesEnergies, 2020
This paper presents a mathematical model that reflects the nature of the dynamic Young’s modulus of a dry sedimentary rock during nonstationary uniaxial loading. The model is based on an idealized model of a system suggested by Jaeger J.C.
