IDA: An implicit, parallelizable method for calculating drainage area
Models of landscape evolution or hydrological processes typically depend on the accurate determination of upslope drainage area from digital elevation data, but such calculations can be very computationally demanding when applied to high-resolution topographic data. To overcome this limitation, we propose calculating drainage area in an implicit, iterative manner using linear solvers. The basis...
متن کاملAn implicit finite difference method for drainage basin evolution
[1] In drainage basin evolution models the implementation of sediment transport and sediment balance is constrained by numerical instabilities. In order to overcome these difficulties an implicit finite difference method is proposed. The method simultaneously adjusts the elevation at each node of the numerical grid, is unconditionally stable, and significantly reduces the computational time. Th...
متن کاملAn Alternating Direction Implicit Method for Modeling of Fluid Flow
This research includes of the numerical modeling of fluids in two-dimensional cavity. The cavity flow is an important theoretical problem. In this research, modeling was carried out based on an alternating direction implicit via Vorticity-Stream function formulation. It evaluates different Reynolds numbers and grid sizes. Therefore, for the flow field analysis and prove of the ability of the sc...
متن کاملA Combinatorial Method for Calculating the Moments of Lévy Area
We present a new way to compute the moments of the Lévy area of a two-dimensional Brownian motion. Our approach uses iterated integrals and combinatorial arguments involving the shuffle product.
متن کاملPleural drainage: an evolving area
I read with interest the paper by Singh and coworkers on the subject of pleural drainage [1]. In the respiratory field, this is a hot topic and guidelines were recently published [2]. Singh and coworkers used a 16-French gauge catheter, which is broadly in agreement with the British Thoracic Society guidelines (and this is what we sometimes use in our hospital). However, the British Thoracic So...
