Large-scale landslide dam breach experiments: Overtopping and “overtopping and seepage” failures

open access: yesEngineering Geology, 2022
Landslide dams form when landslide materials reach rivers causing complete or partial blockage. It is known that overtopping water flows and seepage flows are two crucial processes that induce dam failure. In several instances, the landslide dams collapse is caused by the coupled influence of seepage flows and overtopping water.

Estimation of Wave overtopping on Reshaping Breakwaters [PDF]

open access: yesمحیط زیست و مهندسی آب, 2016
The breakwater as structures that have an important role in the protection of coastal facilities was used to create calm in the harbor, reduce wave energy and also protect the coast against wave attack.

Is a plant truly plastic? Nutrients and neighbours induce trait‐specific responses, but performance depends on response direction

open access: yesOikos, EarlyView.
Plants live in a heterogeneous world, where nutrient and neighbour distributions vary in space and time. Plants can respond to this variation through plastic responses in individual organs, which are assumed to be coordinated among traits to support a coherent, adaptive strategy, maintaining plant growth in varying environments.

Bias in Peak Flood Discharges: Are Our Bridges and Culverts Undersized?

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Reliable methods for peak discharge predictions at ungaged locations are required for infrastructure design and floodplain management. For decades, a standard practice in the United States has been to utilize US Geological Survey regional regression equations (StreamStats) as a singular method. However, implementation of multiple methods, such

Spectral characterization of plant diversity in a biodiversity‐enriched oil palm plantation

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
How well can airborne imaging spectroscopy detect plant diversity in vertically complex agroforestry systems? We tested this in a biodiversity‐enriched oil palm plantation in Sumatra, Indonesia, using high‐resolution hyperspectral data. We calculated spectral alpha and beta diversity and compared them to field‐based plant diversity.

Wave Overtopping at Sea Dikes on Shallow Foreshores: A Review, an Evaluation, and Remaining Challenges

open access: yesJournal of Marine Science and Engineering, 2023
Wave overtopping is a critical parameter in the design of coastal defense structures. Nowadays, several empirical formulations based on small-scale experiments are available in the literature to predict the mean overtopping discharge at dikes on shallow ...

Optimizing Wave Overtopping Energy Converters by ANN Modelling: Evaluating the Overtopping Rate Forecasting as the First Step

open access: yesSustainability, 2021
Artificial neural networks (ANN) are extremely powerful analytical, parallel processing elements that can successfully approximate any complex non-linear process, and which form a key piece in Artificial Intelligence models.

Optimising Wave Energy Plant Location Through Neutrosophic Multi‐Criteria Group Decision‐Making

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT The global shift towards sustainable energy has intensified research into renewable sources, particularly wave energy. Pakistan, with its long coastline, holds significant potential for wave energy development. However, identifying optimal locations for wave energy plants involves evaluating complex, multi‐faceted criteria.

Late‐Holocene evolution of a small Sub‐Arctic glacier, Gljúfurárjökull (Tröllaskagi, northern Iceland)

open access: yesBoreas, EarlyView.
Gljúfurárjökull, located on the Tröllaskagi Peninsula in northern Iceland, is a small glacier approximately 3.8 km in length. This study analyses the glacier's evolution through a combination of methods including: (i) geomorphological mapping, (ii) Cosmic‐Ray Exposure (CRE) dating, (iii) lichenometry and (iv) palaeoglacier reconstruction (volume ...
