Abstract:
... One of the most effective ways to dissipate the destructive energy of water downstream of a flow control structure is the interference of water with air (such as a vertical drop). In this study, the hydraulic parameters of a vertical drop equipped with dual horizontal screens and with the subcritical upstream flow were investigated. Experiments were performed for two drop heights, two porosities, ...

Abstract:
... The recent study of the basement margin to the Nuussuaq Basin, West Greenland, by Jess et al. (2019) illustrates the problems introduced by extracting thermal histories from thermochronology data without taking into account the constraints provided by geological evidence. Their interpretations are incompatible with numerous aspects of the geology of the region, and as a result their conclusions ar ...

Abstract:
... Numerous submarine plateaus form highstanding bathymetric highs at continent to ocean transitions. Due to their proximity to continents, they have been frequently labelled “marginal plateaus”, although this term has not been clearly defined or associated with a specific geology or geodynamic process. Until now, these elevations have been interpreted as submerged thinned continental fragments detac ...

Abstract:
... For the Upper Triassic, conodonts are the primary tools utilized in biostratigraphic investigations. For an effective biostratigraphic zonation, the species should be constrained by clear phylogenetic relationships, in which the stratigraphic ranges and taxonomy are reliable. Unfortunately, a phylogenetic framework for the Late Triassic pectiniform conodonts is almost missing, except for particula ...

Abstract:
... Sequence stratigraphy is commonly used to understand basin history and the distribution of conventional reservoir facies. Establishing a sequence stratigraphic framework in organic-rich mudstone successions is challenging because macroscale sedimentological and petrophysical variations can be subtle, while biostratigraphic and seismic data may be unavailable or of limited use. For these reasons, i ...

Abstract:
... Aggregation is used to represent the real world in a model at an appropriate level of abstraction.

We highlight how all models depend on some forms o ...

Abstract:
... Microfibres are one of the most ubiquitous particulate pollutants, occurring in all environmental compartments. They are often assumed to be microplastics, but include natural as well as synthetic textile fibres and are perhaps best treated as a separate class of pollutants given the challenges they pose in terms of identification and contamination. Microfibres have been largely ignored by traditi ...

Abstract:

The framework first calibrates parameters for each catchment/sub-basin sequentially and then fine-tunes parameters as needed. We implemented a comprehensive learning particle swarm optimiser (CLPSO) as the calibrator and applied the two-step CLPSO tool in calibrating parameters of a water ac ...

In the surrounding area sizable coseismic surface deformation were catalogued, attesting the severity of earthquake, the proximity to the causative fault and the geo ...
