Análisis y optimización de redes sismológicas. Aplicación al estudio de la sismicidad natural e inducida por embalses
(Sociedad Geológica de España, 1996)A methodology is proposed with the goal of obtaining optimal configurations of local seismological networks. This is performed by the analysis o f characteristic parameters like covariance matrix , condition number, etc. ... -
Características geológicas del borde suroccidental de la unidad hidrogeológica 04.04 y su influencia sobre la hidrogeología de las Tablas de Daimiel
(Sociedad Geológica de España, 1996)La Mancha Occidental (also called Hydrogeological Unit 04.04) is located in the castilian submesete and has a surface of 5.500 km2.The Tablas de Daimiel and Ojos del Guadiana wetlands were placed in the SW border of this ... -
Modelización del comportamiento dinámico de los suelos granulares densos. Movilidad cíclica
(Sociedad Geológica de España, 1996)This paper shows the results of the mathematical simulation of the dynamic behaviour of a dense granular soil when tested in a triaxial device. Under these conditions and due to the capability of these soils to increment ... -
Resultados preliminares de la aplicación de lodos de depuradoras como fertilizante y su implicación en la migración de nitratos a través de de la zona no saturada
(Sociedad Geológica de España, 1996)The results of field experiments over use of the composted sewage sludge compared with mineral fertilizer in corn crops are presented. Also, the nitrate leaching through the unsaturated zone and its arrival to groundwater ... -
Análisis de la evolución de los resultados de la prueba de selectividad (Geología) en la Universidad de Castilla-La Mancha en el periodo 1988-1995
(Sociedad Geológica de España, 1996)After seven years of experience in a project, controlled from its beginning by the C.O .U. (University Orientation Academic Year) coordination group of Castilla-La Mancha University, now we present the results of the ... -
Una aplicación didáctica en "Cartografía Ambiental y Ecológica": propuesta de reforestación con criterios ambientales
(Sociedad Geológica de España, 1996)Making, using and interpreting maps is necessary in Environmental and Earth's Sciences. This paper shows the foundations and methodology to realize an exercise proposed to universitary students of the matter «Environmental ... -
Ensayos experimentales del flujo del agua y la distribución de la conductividad eléctrica en perfiles de la zona no saturada próximos a un vertedero de residuos sólidos urbanos
(Sociedad Geológica de España, 1996)We present some results about water content, hydraulic conductivity, water flow, pH, organic matter and electrical conductivity determinated in soil samples from unsaturated zone profiles made in a discharge area located ... -
Aportaciones recientes sobre "Didáctica de la Geología" en revistas españolas
(Sociedad Geológica de España, 1996)It seems interesting to carry out a revision of the works about Didactics of Geology published in Spanish reviews in order to get an idea on the whole of the state o f this subject. The present papel offers the results of ... -
Aplicación de técnicas de Geo-Radar para el estudio del tapón de jet-grouting inyectado en los túneles del metro
(Sociedad Geológica de España, 1996)Several kilometers o f tunnel have been excavated to extend a metropolitan underground system. In some places, where the subsurface is mainly composed by gravel and sands, water can easly penetrate causing problems to the ... -
Estabilidad de los minerales de la arcilla en las relaciones de interacción arcosas-agua subterránea en el acuífero de Campo Arañuelo
(Sociedad Geológica de España, 1996)The equilibrium state of silicate minerals with groundwater in an aquifer can be known from the saturation state obtained by speciation codes, like WATEQ4F, or from stability mineral diagrams. In the study of the ground ... -
Simulación física y numérica de las avalanchas de nieve en Francia
(Sociedad Geológica de España, 1996)In this paper are presented and described the main characteristics of the different kind of snow avalanches. We distinguishes two great families : dense and powder avalanches. Their releasing conditions are reminded and ... -
Descripción del comportamiento tensodeformacional de los suelos granulares. Teoría del estado crítico
(Sociedad Geológica de España, 1996)The main features of the stress - strain behaviour of granular soils are described in this paper on the basis o f the typical results of triaxial tests. The principal feature of this behaviour consists on the capability ... -
El fenómeno de "scaling" en los sistemas kársticos
(Sociedad Geológica de España, 1996)In this work we preset a different sistemathic methodology to analyse the geomorphology o f the karstic cave systems, with the aim to show how the same behaviour, in roughness, appears at different working scales. This ... -
Modelos termodinámicos y de balance y transferencia de masas entre las aguas subterráneas y las rocas graníticas del Sistema Central (Cuenca del Alberche)
(Sociedad Geológica de España, 1996)The main porpuse of this work is to describe the relationship between the grounwater and the mineral composition of the granitic rocks in the meridional region of the Alberche river basin. We construct several geochemical ... -
Isótopos ambientales en las aguas subterráneas del macizo ígneo-metamórfico del Sistema Central (Cuenca del Alberche)
(Sociedad Geológica de España, 1996)The results of isotopic analyses - deuterium , oxygen-18 and tritium - are discussed for ground water samples obtained from severals wells and springs with different chemical types, located in the crystalline basin of the ... -
Los depósitos de deslizamientos gravitacionales del centro-sur de Gran Canaria
(Sociedad Geológica de España, 1996)Landslide deposits of Gran Canaria were poorly understood before 7990. Our survey has shown that these deposits are composed of large translational landslides, attaining volumes up to TO9 m3. A total of 28 landslides have ... -
