| dc.description | La investigación de procesos de migración de gases a través de suelos normalmente presenta dificultades debido principal-mente a la naturaleza no homogénea del suelo; esto limita la capacidad de modelar los procesos apropiadamente tanto para describirlos como para predecirlos. El Simulador de Migración de Gases en Suelos (GAMS) se desarrolló para resolver este problema. El GAMS consta de un recipiente cilíndrico, el cual puede llenarse homogéneamente con un volumen conocido de suelo. El diseño del GAMS permite una entrada difusiva de cierta fase gaseosa en la base de la columna de suelo, lo que al mismo tiempo permite investigar la velocidad de exhalación del gas. El diseño permite además efectuar una irrigación cuantitativa de la superficie del suelo y simular niveles hidrostáticos ajustables. Para registrar series de tiempo de los parámetros más relevantes, el GAMS el GAMS está equipado con seis capas de monitores intercambiables a diferente profundidad. Las investigaciones más recientes empleando el GAMS se enfocan a la migración de radón a través del suelo y su dependencia con la temperatura y contenido de humedad del suelo utilizando monitores “Clipperton”. | es-ES |
| dc.description | Since natural soil conditions are hardly ever homogeneous, soil gas migration processes are difficult to investigate. The power of model calculations for describing or predicting soil gas migration processes is often limited. The Gas-Migration-Simulator (GAMS) has been developed to cope with this problem. The GAMS takes the form of a cylindrical box which can be homogeneously filled with a soil volume of 1.7 m3. The design allows a solely diffusive input of a gas phase into the base of the soil column. At the same time it allows determination of the gas exhalation rate. By providing a gas-tight crawling space immediately above the soil column and by adjusting a certain air pressure in this space the GAMS also permits the simulation of atmospheric high or low pressure fields, enabling the investigation of their influence on soil gas exhalation rate and soil gas migration. Quantitative irrigation of the soil surface and simulation of an adjustable groundwater table are also possible. To record time series of the relevant parameters, the GAMS is equipped with six layers of exchangeable probes at different depths. Recent research focuses on the migration of radon through the ground and its dependence on meteorological parameters. Special “Clipperton” probes have been used to record continuous time series of radon concentration of soil gas together with the temperature and the soil moisture content. | en-US |
