ISSN:
0022-1694
Subject:
hydrology; methodology; models; porosity; porous media
Abstract:
... Single and multiphase flows in fractured porous media at the scale of natural reservoirs are often handled by resorting to homogenized models that avoid the heavy computations associated with a complete discretization of both fractures and matrix blocks. For example, the two overlapping continua (fractures and matrix) of a dual porosity system are coupled by way of fluid flux exchanges that deeply ...

Abstract:
... The use of micro-lysimeters (MLs) by the scientific community for the measurement of non-rainfall water input, NRWI (dew, fog, water vapor) has become more widespread. With MLs being isolated bodies, we hypothesized that changes in heat flux may affect the surface temperatures and subsequently NRWI. Measurements were conducted with MLs of various lengths (3.5, 12, 20, 30, 40, 50cm for 2014 and 3.5 ...

Due to the lack of field measurements, different methods have been proposed to estimate RZSM, including the use of exponential filters to predict RZSM from remotely sensed near surface soil moisture data. However, inconsistent findings about the controls on the optima ...
