Riparian zones in semi-arid regions often exhibit high rates of evapotranspiration (ET) in spite of low soil moisture content due to vegetation that is able to withdraw water from shallow aquifers. This work better defines the relationship between ET and the saturated zone by comparing the observed water table drawdown to analytically modeled drawdown in fully penetrating wells of an unconfined...

to control the nonlinear numerical instability, throughout the time evolution of the eulerian form of the nonlinear rotating shallow water equations, it is necessary to add numerical diffusion to the solution. it is clear that, this extra numerical diffusion degrades the accuracy of the numerical solution and should be kept as small as possible. in a conventional approach a hyper-diffusion is u...

With the recent development of deep convolutional neural networks and large-scale datasets, face recognition has made remarkable progress been widely used in various applications. However, unlike existing public many real-world scenarios recognition, depth training dataset is shallow, which means that only two images are available for each ID. non-uniform increase samples, such issue converted ...

Global atmospheric circulation models (GCM) typically have three primary algorithmic components: columnar physics, spectral tran-form, and semi-Lagrangian transport. In this study, several varients of a SLT method are studied in the context of test cases for the shallow water equations in spherical geometry. A grid point formulation is used with implicit, semi-implicit or explicit time integrat...

We give an exponentially-accurate normal form for a Lagrangian particle moving in a rotating shallow-water system in the semi-geostrophic limit, which describes the motion in the region of an exponentially-accurate slow manifold (a region of phase space for which dynamics on the fast scale are exponentially small in the Rossby number). We show how this result is related to the variational asymp...
