2013 —
WHEEA522DB912
Researchers have developed a novel method to derive critical rainfall thresholds (CRT) for shallow landslides, which can be used as a tool for debris flow early warning systems. This approach overcomes limitations associated with empirical methods when historical data is scarce or environmental conditions change over time. The methodology involves mathematical and numerical simulations based on the infinite-slope stability model, where slope instability is governed by increased groundwater pressure due to rainfall. The effect of rainfall infiltration on landslide occurrence is modeled using a reduced form of the Richards equation. The study investigates the range of rainfall durations for which this method can be accurately employed and derives an equation for its lower limit. A large number of simulations were performed, combining different values of rainfall characteristics such as intensity and duration of event rainfall, as well as antecedent rainfall intensity. For each combination, the percentage of basin instability was computed, forming a database used to derive CRT curves. The methodology was tested in a small basin on the Amalfi Coast, Italy, showing good agreement with observed rainfall amounts during a playback period. The study also highlights that the lack of knowledge about soil parameter variability can significantly affect results, which is partially mitigated by using a Monte Carlo approach.

Researchers determined that the Hierapolis theater near Pamukkale, Turkey, exhibits a statistically significant elliptical shape when analyzed using precise surveying techniques. By employing an electronic total station instrument and applying an ellipse-fitting algorithm, the study assessed the geometric form of the theater's rings. Statistical testing revealed that an elliptical model best represents the theater's structure, providing insights into its architectural design. This finding challenges assumptions about circularity in ancient theaters and offers a method for characterizing similar heritage sites.

A comparative study of Lijiang Old Town and China’s Lane in Chengdu reveals that while China’s Lane outperforms Lijiang in sustainable cultural heritage tourism development due to stronger government guidance and segregation systems, both sites face declining cultural authenticity primarily caused by the displacement of indigenous populations and disruption of local community networks. The research underscores the need for governments to shift from dominant control to supportive guidance roles, adopt effective right segregation management, and establish comprehensive assessment mechanisms to ensure long-term sustainability. It also highlights the critical importance of preserving cultural authenticity and local community structures as foundational elements for sustainable heritage tourism.
