Effect of Submerged Vegetation on Water Surface Geometry and Air–Water Momentum Transfer

Geophysical Research Letters
Understanding how submerged vegetation modifies the water surface is crucial for modeling momentum exchange between shallow waters and the atmosphere. In particular, quantifying its impact on the equivalent aerodynamic roughness of the water surface is ...

Rede urbana e redes de serviços bancários, postais e educacionais do Rio Grande do Norte: coexistências de hierarquias

Confins, 2017
The urban network of Rio Grande do Norte in the current period displays a configuration resulting from the characteristics of the technical-scientific-informational period in which emerges a superposition of networks that cohabit in that territory.

L’(in)efficacité géomorphologique des cascades sédimentaires en question : les apports d’une analyse réseau

Cybergeo, 2016
The formalization of sediments cascades within a catchment is one of the main field research in geomorphology. Since the pioneering studies on geomorphic open systems, inefficient sediment exportation at catchment sinks has been widely observed.

Numerical algorithms for solving problems of multiphase flows in porous media

Mathematical Modelling and Analysis, 2006
In this paper we discuss numerical algorithms for solving the system of nonlinear PDEs, arising in modelling of two‐phase flows in porous media, as well as the proper object oriented implementation of these algorithms.

Methodological aspects of a questionnaire researching transportation links

Transport, 2005
Changes of foreign trade conditions also bring changes of the main transport routes and directions. Lithuanian transport companies must perfect their ability to adapt in changing environment, to predict and reorient to the possible changes in the flow of
