Experimental study on local scour around large-diameter submerged cylinders under combined waves and current action

Shui kexue jinzhan, 2019
The characteristics of local scour around large-diameter submerged cylinders are quite different from the non-submerged ones under combined wave and current conditions. Local scour model tests are carried out in a wave-current flume. A submerged cylinder

Harnessing Spatial and Multi‐Criteria Decision Analysis (MCDA) to Optimize Land Suitability for Kenaf Cultivation in Kelantan: Pathways for Sustainable Economic Development

Land Degradation &Development, EarlyView.
ABSTRACT In Kelantan, entrenched land degradation and extensive idling of agricultural lands exacerbate rural poverty. Current top‐down planning often overlooks local geographic and social constraints, despite state initiatives to convert idle lands and strengthen rural livelihoods.

Wave–Current Force Characteristics of Monopile Foundations on Scoured Seabeds

Journal of Marine Science and Engineering
Local scour around offshore wind turbine foundations is a common engineering challenge. It changes the hydrodynamic loads and affects the foundation’s load-bearing capacity.

LOCAL SCOUR AMD CURRENT AROUND A POROUS BREAKWATER

Coastal Engineering Proceedings, 1976
Scour at the foot of vertical homogeneous crib style walls which were used as models for detached breakwaters, and the rise of mean water level in the shoreside region of the breakwaters were experimentally investigated, and the experimental results were compared to some field data.

Characteristics and Influencing Factors of Soil Shear Strength in Gully Erosion at Different Developmental Segments of Subalpine Meadows

Land Degradation &Development, EarlyView.
ABSTRACT Subalpine meadows play important roles in biodiversity conservation and soil carbon sequestration, but gully erosion poses a serious threat to their ecological stability. Soil shear strength (τ) is a key mechanical parameter for evaluating gully stability and soil resistance to failure. However, the spatial variation in soil shear strength and

Evaluation of methods for the analysis of oxygen and carbon dioxide in water, sediment, litter, and soil

Limnology and Oceanography: Methods, EarlyView.
Abstract Choosing an appropriate analyzer to measure concentrations of oxygen (O2) and carbon dioxide (CO2) during biogeochemical cycling studies can be difficult, considering the range of options available. While several studies examine the abilities of specific analyzers, comparison of multiple analyzers and environmental sample types is lacking.

Integrating and assessing metacommunity drivers of ecosystem function and resilience in benthic algal systems

Oikos, EarlyView.
Understanding the scales and mechanisms by which species composition interacts with ecosystem functions is critical for forecasting the effects of environmental perturbations on ecosystem services. However, the linkages between what regulates the ecosystem functions of dispersal‐capable networks of communities (metacommunities) and what regulates a ...

SIMULATION OF SCOURING AROUND A VERTICAL CYLINDER DUE TO TSUNAMI [PDF]

Science of Tsunami Hazards, 2017
* Corresponding author radianta@ugm.ac.id ABSTRACT Local scour due to tsunami is damaging especially on shallow foundation. Although relatively in a short duration, tsunami attack may scour material around buildings that led to destruction. A number of
