Phosphorus losses from land to water will be impacted by climate change and management for food production, with detrimental impacts on aquatic ecosystems. Here we use a unique combination of methods evaluate the impact projected future phosphorus transfers, assess what scale agricultural would needed mitigate these transfers. We combine novel high-frequency flux data three representative catchments across UK, new high-spatial resolution model, uncertainty estimates an ensemble simulations,...
We hypothesise that climate change, together with intensive agricultural systems, will increase the transfer of pollutants from land to water and impact on stream health. This study builds, for first time, an integrated assessment nutrient transfers, bringing a) high-frequency data outlets two surface water-dominated, headwater (~ 10 km2) catchments, b) event-by-event analysis c) concentration duration curves comparison EU Water Framework Directive quality targets, d) event...
This paper presents the design and construction of a deep excavation for building foundations in saturated soil. was particular interest because it located above beside Shanghai Metro tunnels. The twin tunnels had to be full operation during excavation. Potential large deformation one main concerns discusses detail criteria measures controlling soil tunnel deformation. included cast-in-place concrete diaphragm walls with bracing structural members, pumping consolidation, cementsoil mix pile...
A numerical solution for shallow-water flow is developed based on the unsteady Reynolds-averaged Navier–Stokes equations without conventional assumption of hydrostatic pressure. Instead, non-hydrostatic pressure component may be added in regions where its influence significant, notably bed slope not small and separation a vertical plane occur or free-surface small. The are solved σ-co-ordinate system with semi-implicit time stepping eddy viscosity calculated using standard k–ϵ turbulence...
There is a need to model and predict the transfer of phosphorus (P) from land water, but this challenging because large number complex physical biogeochemical processes involved. This study presents, for first time, 'limits acceptability' approach Generalized Likelihood Uncertainty Estimation (GLUE) framework Soil Water Assessment Tool (SWAT), in an application water quality problem Newby Beck catchment (12.5 km2), Cumbria, United Kingdom (UK). Using high frequency outlet data (discharge P),...
Dam-break flows in general geometries with complex bed topography are simulated numerically using a high-resolution Godunov-type cut cell method. The model is based on the shallow water equations appropriate source terms. A vertical step treated efficiently and accurately surface gradient For dam-break occurring complicated geometries, Cartesian method together transmissive boundary conditions incorporated. Verification of carried out by predicting typical practical situations, i.e., over...

The effect the step on flows modelled with equations including local energy loss terms. elevation denoted z b ‐ left and + right values at each grid point, hence exactly representing a discontinuity topography. surface gradient method (SGM) generalized to reconstruct depths cell interfaces involving so that fluxes can accurately be calculated Riemann solver. verified by predicting surge...
A lattice Boltzmann method is developed for incompressible axisymmetric flows. Both force and source or sink terms are incorporated into the equation in a natural way, which consistent dimension with equation. The correct macroscopic equations flows recovered through Chapman-Enskog expansion. It turns out that added nothing but additional governing compared Navier-Stokes equations, resulting simple efficient model. This provides an unique advantage proposed scheme naturally suitable general...
Bitcoin (BTC) is known for its exceptional return potential, but this comes with high volatility which makes it a high-risk, high-reward investment. This paper examines Bitcoin's risk-return pattern compared to traditional assets (DXY, GLD, SPY and QQQ). We apply key indicators such as annualized return, volatility, sharp ratio, skewness, kurtosis explore the risk of Bitcoin. find that has higher investment assets, much maximum drawdown. In addition, we combine different proportions...
As an unconventional gas reservoir, bauxite reservoirs have often been studied as weathered crust cover layers rather than in the past. The Taiyuan Formation Longdong area of Ordos Basin has achieved breakthroughs, and some wells obtained industrial airflow. Therefore, it is necessary to conduct basic geological research on reservoir. application casting thin sections, scanning electron microscopy (SEM), X-ray diffraction (XRD), high-pressure mercury injection (HPMI), low-temperature...

The two-dimensional shallow-water flow equations are first written in strong conservation form and used for developing the model. In discretization equations, based on control volume method, velocity field is found to be proportional both square of depth itself. Due this, none existing SIMPLE-like algorithms can deal with velocity-depth coupling. this paper, problem coupling studied, a modified algorithm described treat it. Several applications model have shown that method efficient, simple,...
