Conceptualisation of geo-hydrological characteristic erosive runoff are particular importance and has been required in recent soil erosion control. This study aimed to explore the feasibility applying hydrological attributes characterize surface pathways process hillslope due rainfall. Combined with sub-millimeter high-resolution laser scanning computer digital image processing method, three in...

A statistical approach to LiDAR derived topographic attributes for the automatic extraction of channel network and for the choice of the scale to apply for parameter evaluation is presented in this paper. The basis of this approach is to use distribution analysis and statistical descriptors to identify channels where terrain geometry denotes significant convergences. Two case study areas with d...

The paper describes aspects of research being undertaken on the determination and processing of digital elevation models. A 2-D Kalman filter has been developed based on dynamic and functional models for a grid DEM, to produce optimal estimates of terrain attributes of a DEM point using the relevant observations, and predictions derived from its orthogonal neighbouring points. A further method ...

by considering the fact that the surface tension of a real fluid arises from a combination of both repulsive and attractive forces between molecules, a new expression for the interfacial tension has been derived from scaled particle theory (spt)  based on the work of cavity formation and the interaction energy between molecules. at the critical temperature, the interfacial tension between coexi...

Abstract. The absence of a compiled large-scale catchment characteristics dataset is key obstacle limiting the development large-sample hydrology research in China. We introduce first attribute diverse data sources, including soil, land cover, climate, topography, and geology, to develop dataset. also includes catchment-scale 31-year meteorological time series from 1990 2020 for each basin. Pot...

The Front Cover shows UO2 nanoparticles with a pictorial representation of the atoms (uranium in blue and oxygen red). In this work, user-defined X-ray absorption spectroscopy models informed by surface relaxation effects inherent disorder were generated preferentially fit to experimentally derived data. developed method enables representative local structure attributes be extracted from bulk R...

Recent theory and experimental work in metapopulations and metacommunities demonstrates that long-term persistence is maximized when the rate at which individuals disperse among patches within the system is intermediate; if too low, local extinctions are more frequent than recolonizations, increasing the chance of regional-scale extinctions, and if too high, dynamics exhibit region-wide synchro...

The purpose of this study is to examine the relationship between local government services and the overall satisfaction of users with the e–recruitment website (e–job website) in Taiwan. A two–dimensional mean value matrix (TDMVM) technique was used to explore the identification, classification, and application of website service quality. The results show that the asymmetrical relationship betw...
