The ability of transformers to perform precision tasks such as question answering, Natural Language Inference (NLI) or summarizing, has enabled them be ranked one the best paradigms address Processing (NLP) tasks. NLI is scenarios test these architectures, due knowledge required understand complex sentences and established relationships between a hypothesis premise. Nevertheless, models suffer ...

The extreme 2010-2011 wet season resulted in highly elevated Burdekin River discharge into the Great Barrier Reef lagoon for a period of 200 days, resulting in a large flood plume extending >50km offshore and >100km north during peak conditions. Export of suspended sediment was dominated by clay and fine silt fractions and most sediment initially settled within ∼10km of the river mouth. Biologi...

A field trial was conducted to test the existence of subsonic (Vp < 331 m/s) P-waves previously reported in the literature. A 1-m-long reverse profile was acquired with three-component (3C) geophones on a sandy silt (unified classification ML). The silt had a porosity of 54%, a degree of water saturation of 63%, and a plasticity index of 10. No subsonic P-waves were observed, although highfrequ...

Sedimentary dispersal systems with fine-grained beds are common, yet the physics of sediment movement within them remains poorly constrained. We analyze sediment transport data for the best-documented, fine-grained river worldwide, the Huanghe (Yellow River) of China, where sediment flux is underpredicted by an order of magnitude according to well-accepted sediment transport relations. Our theo...

The Himalayan Rivers due to their steep bed and side slopes, narrow width and fragile geology of the region carry huge amount of sediment with them. Many runof-river hydro power projects are coming up on these rivers and suspended sediment enters into the power intake of these projects. Desilting chambers are provided to remove / minimize the suspended sediment from water conductor system. The ...
