of the many climatic events that influence the earth’s environment, drought is perhaps the one that is most linked with desertification. drought is the consequence of a natural reduction in the amount of precipitation received over an extended period, usually a season or more in length. drought monitoring is an essential component of drought risk management. it is normally performed using vario...

On the morning of the 25 of April 1998, an accidental spill of the waste damp basin of the Aznalcóllar mine (Seville, SW Spain) occurred. The basin, containing mud and acid waters, suffered a rupture spilling 4 hm of acid waters and 2 hm of acid mud directly into the Agrio and Guadiamar rivers. This accidental spill spread to an area of about 49 km and they had very important ecological consequ...

With the advent of post-epidemic era, China's tourism industry has increased significantly. So there is a need for large number people who are proficient in travel English. However, training professionals China somewhat backward. This paper analyzes problems existing listening and speaking teaching Tourism English higher vocational colleges, applies schema theory to this application colleges fr...

Uniaxial compressive strength (UCS) is one of the most significant factors on the stability of underground excavation projects. Most of the time, this factor can be obtained by exploratory boreholes evaluation. Due to the large distance between exploratory boreholes in the majority of geotechnical projects, the application of geostatistical methods has increased as an estimator of rock mass pro...

[1] This study presents monthly CO2 fluxes from 1997 to 2001 at a 3.75 latitude 5 longitude resolution, inferred using a geostatistical inverse modeling approach. The approach focuses on quantifying the information content of measurements from the NOAA-ESRL cooperative air sampling network with regard to the global CO2 budget at different spatial and temporal scales. The geostatistical approach...
