The geomorphometry of endorheic drainage basins: implications for interpreting and modelling their evolution
(2013)
Endorheic basins are catchments with no hydrological connection with marine environments. They cover 20% of the Earth's surface, and are mostly located in arid regions. Their drainage networks converge to lakes, salt flats ...
SatRed: New classification land use/land cover model based on multi-spectral satellite images and neural networks applied to a semiarid valley of Patagonia
(Elsevier, 2022-02)
In this article we describe a new model, SatRed, which classifies land use and land cover (LULC) from Sentinel-2 imagery and data acquired in the field. SatRed performs pixel-level classification and is based on a ...
Performance assessment of two-dimensional hydraulic models for generation of flood inundation maps in mountain river basins
(2019)
Abstract Hydraulic models for the generation of flood inundation maps are not commonly applied in mountain river basins because of the difficulty in modeling the hydraulic behavior and the complex topography. This paper ...

Stochastic fractured rock facies for groundwater flow modeling
(Universidad Nacional de Colombia Sede Medellín, 2013)
This paper presents simulation results of groundwater flow in fractured rocks. A stochastic approach is employed to build the conceptual model, a stochastic Equivalent Porous Medium fractured rock facies model, for the ...
Comparação entre modelagem numérica e experimento de campo em escala real para um sistema de cobertura na Mina Fazenda Brasileiro (Bahia)
(Universidade Federal de Minas GeraisUFMG, 2014-06-05)
The concern about the closure of mines after the end of their activities is recent in Brazil, where discussions about this subject began only some years ago. Here, in most cases, the mining wastes are disposed in mud form ...
