متن کاملAssessing sinkhole activity in the Ebro Valley mantled evaporite karst using 1 advanced
19 Sinkholes in karst areas may cause subsidence damage in transportation infrastructures, 20 demolition of buildings and even the loss of human lives when they occur in a 21 catastrophic way. Differential Interferometry (DInSAR) is a promising technology for 22 detecting and characterizing sinkholes, as well as for reducing the associated risk when 23 combined with other sources of data such a...
متن کاملAlluvial sinkholes over gypsum in the Ebro basin ( Spain ) : genesis and environmental impact
The Ebro Basin is located in the northeast of Spain. Its central part is filled with gypsum and carbonate deposits of Neogene age. Quaternary sediments overlie the Tertiary layers. Alluvial sinkholes have developed in this region, causing high economic losses. From the study of aerial photographs, from the compilation of historical cases of collapse and from data on the lithological characteris...
متن کاملMartian Sinkholes: Implications for Large Scale Evaporite
Introduction. The current hypothesis is that Martian sinkholes do not exist. It is proposed that the low pH environment resulting from the high CO2 content of the atmosphere will cause calcium carbonate to be deposited as calcite cemented sandstone rather than limestone [5]. Calcite, as well as gypsum, halite, smectite and illite, has been detected in Martian meteorites providing proof of the p...
متن کاملIrrigation return flows and phosphorus transport in the Middle Ebro River Valley (Spain)
Currently, there is an increased interest in the study of phosphorus (P) loss from soils aimed to understand and mitigate water eutrophication problems. The main objective of this study is to describe P losses in f ive irrigated agricultural watersheds considered as representative in terms of agricultural water management. Weekly water samples were collected during the 2007 hydrologic year (HY)...
