“…The regionally extended carbonate rock volume can be handled simply as a special type of a hydrogeological environment (Tóth 1971(Tóth , 1984 where the rock matrix basically consists of soluble formations with relatively high hydraulic conductivities. These formations can be fully or partially covered by siliciclastic sediments (Ford and Williams 2007c).…”

The peculiarities of karst environment make it highly vulnerable to a number of geohazards: As concerns the natural hazards, the main categories are sinkholes, slope movements, and floods. To these, anthropogenic hazards have to be added, as pollution events, land use changes resulting in loss of karst landscape, destruction of karst landforms, etc. Even carrying out engineering works without taking into the due consideration, the peculiar aspects of karst can be extremely dangerous and cause risk to the natural environment, as well as to the man-made infrastructures and buildings. In the second half of last century, man has definitely become one of the most powerful factors that can cause changes in the karst environment, produce direct damage, predispose the territory to threatening events, and increase with mismanagement actions the negative effects deriving from natural hazards. In this chapter, the main hazards in karst are briefly described with particular focus on the natural hazards and with the help of some case studies

“…The presence of ascending groundwater flows in discharge areas as a result of topography, driven flows is an unquestionable hydraulic fact (Hubbert, 1940;Toth, 1963), which has an important impact on the landscape and on the vegetation (Bernáldez et al, 1987) and which actively intervenes in numerous geological and geomorphological processes (Toth, 1971(Toth, , 1999, including the formation of saline wetlands (Toth, 1980;Herrera and Sastre 1983;Hendry and Duckland 1999;Salama et al, 1999) and salt lakes (Sánchez et al, 1998).…”

Abstract:Presence of groundwater flow in the 'Somontano de Huesca' Area, derived from low-permeability detrital Tertiary rocks, is considered. A groundwater flow model is constructed for these Tertiary rocks. This model explains both water flow through them and the chemical characteristics of the water.Groundwater flow has clear surface manifestations: it causes wetlands (which are called 'paules' in the area) with sodic waters, it produces saline, sodic or alkaline soils, and it produces modifies the chemical composition of rivers in Somontano.Irrigation has increased the volume of filtered water, especially in the interfluve areas, causing the extension of the wetlands in the valley thalwegs, and also the greater movement of salts has increased the problems of saline and/or sodic soils in the area.

“…La presencia de suelos salinos en la cuenca del Ebro ha sido objeto de numerosos estudios (Alberto et aL, 1979;Herrero, 1982;Cuchi, 1986); todos ellos, si bien muy documentados en datos edafológicos y químicos, no consideran, en la génesis de estos suelos la existencia de flujos ascendentes de agua -hecho hidráulico incuestionable (Hubbert, 1940;Toth, 1963)-de gran impacto en el paisaje y la vegetación (Bernáldez el al., 1987); así como generadores de procesos geológicos y morfológicos (Toth, 1971 ), entre ellos los suelos salinos (Leskiw, 1971;Toth, 1980;Herrera et aL, 1983). En el presente trabajo se ha realizado un muestreo hidroquímico, tanto de las aguas subterráneas del Terciario detrítico como de todos los manantiales y zonas húmedas observados en el somontano de Huesca; asimismo se han muestreado los ríos prepirenaicos en diferentes tramos ( fig.…”

RESUMENSe considera la presencia en el Somontano Oscense de flujos de agua subterránea procedentes de materiales detríticos terciarios de baja permeabilidad. Se da un modelo de flujo de las aguas subterráneas en estos materiales que permite explicar tanto su fluencia hacia la superficie como sus características fisico-químicas.Estos flujos se manifiestan en superficie, dando lugar a zonas húmedas naturales, pauJes, con aguas de composición sódica que provocan la formación de suelos salinos, sódicos o alcalinos; también se manifiestan modificando la composición química de las aguas de los ríos que atraviesan el Somontano.Palabras clave: Hidrogeología, hidroquímica, humedales, suelos salinos, suelos sódicos, cuenca del Ebro, Huesca, España.
