Superposition principle for short-term solutions of Richards' equation:...
AbstractThe interaction of a wetting front with an impervious layer is described by adding a reflected solution to the incoming solution for a semi-infinite medium. It is shown and checked by...
View ArticleInteraction of wetting fronts with an impervious surface — Longer time behaviour
AbstractThe interaction of a wetting front with an impervious surface can be described very easily in the early stages of interaction by using a superposition principle. After the time when the...
View ArticleSorptivity calculation for arbitrary diffusivity
AbstractAn estimate of the sorptivity that requires only the knowledge of simple integrals of the soil-water diffusivity weighted by a power of the water content is present. The result is checked...
View ArticleA multifractal analysis of lidar measured water vapour
AbstractAccurate and fast-response measurements of space-time observations of specific humidity were made above a drying land surface at the University of California at Davis, using the Los Alamos...
View ArticleApproximate Analytical Solution of the Nonlinear Diffusion Equation for...
AbstractA general approximation for the solution of the one-dimensional nonlinear diffusion equation is presented. It applies to arbitrary soil properties and boundary conditions. The approximation...
View ArticlePhysics and modeling of small scale turbulence for large eddy simulation
AbstractAn important open question for Large Eddy Simulation (LES) of turbulent flow is whether the subgrid-scales (smaller than A) and the associated stresses can be described by universal models....
View ArticleOn an Exact Analytical Solution of the Boussinesq Equation
AbstractA useful exact analytical solution of the Boussinesq equation is discussed and is the most general solution presently available, and in particular yields a solution for a finite aquifer. It...
View ArticleEstimation of urban sensible heat flux using a dense wireless network of...
AbstractThe determination of the sensible heat flux over urban terrain is challenging due to irregular surface geometry and surface types. To address this, in 2006–07, a major field campaign (LUCE)...
View ArticleModelling Small-Scale Drifting Snow with a Lagrangian Stochastic Model Based...
AbstractObservations of drifting snow on small scales have shown that, in spite of nearly steady winds, the snow mass flux can strongly fluctuate in time and space. Most drifting snow models, however,...
View ArticleSpatial Characteristics of Roughness Sublayer Mean Flow and Turbulence Over a...
AbstractSingle-point measurements from towers in cities cannot properly quantify the impact of all terms in the turbulent kinetic energy (TKE) budget and are often not representative of...
View ArticlePerturbations to the Spatial and Temporal Characteristics of the...
AbstractThe effect of extensive terrestrial wind farms on the spatio-temporal structure of the diurnally-evolving atmospheric boundary layer is explored. High-resolution large-eddy simulations of a...

AbstractThe Nieuwstadt closed-form solution for the stationary Ekman layer is generalized for katabatic flows within the conceptual framework of the Prandtl model. The proposed solution is valid for...
