Honeycomb weathering is a common phenomenon found on various rock surfaces all around the world. However, honeycomb formation mechanisms are still poorly understood. In this study, we propose model describing moisture transport within sandstone and erosion resulting from salt deposition during evaporation of off surface. The based non-linear diffusion equation, where volumetric content combined...
Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract A multi-layer land surface model (SOLVEG) is dynamically coupled to the non-hydrostatic atmospheric model (MM5) in order to represent better spatial variations and changes in land surface characteristics compared with the land surface para...
The Soil Moisture and Ocean Salinity (SMOS) mission, developed by the European Space Agency (ESA), will be launched in the second half of 2009. It will be the first L-band (~1.4 GHz) passive microwave satellite specifically designed for global soil moisture observations, with an expected accuracy for the retrieved soil moisture of ~0.04 m/m. While passive microwave observations have been widely...
Extended abstract 1- INTRODUCTION In the arid and semi-arid areas of Asia, dust storms occur frequently. Much progress has been made in the monitoring modeling and prediction of Asian dust storms. Dust emission is caused by wind erosion in the sensitive areas. Wind erosion is described as the transportation of soil particles by means of the wind. Soil Surface moisture is one of the most i...
Soil moisture is one of the main input parameters in many models for monitoring and predicting crop yield. The ability of mathematical models has allowed correct application of brackish water and selection of management options. The purpose of this research was to evaluate the performance of HYDRUS-2D for simulating soil volumetric water content in a heterogeneous heavy soil under field conditi...
