Examplesofaquiferaquifer Then the water composition approximately oscillates at each point of theaquiferin phase with the water velocity. From theCambridge English Corpus The efficiency of the mechanism may be one of the selection factors at some stages of the chemical evolution in theaquifer. From theCambridge English Corpus The alternating water flow produces temperature and water composition oscillations in theaquifer. From theCambridge English Corpus A watershed development program aiming at recharging aquifers, facilitating sustainable groundwater use, is the focus of this study. From theCambridge English Corpus According to the mechanism, the particles in anaquiferare moved by an alternating flow of ground water. From theCambridge English Corpus The proposed mechanism permits the concentration of particles in some regions of theaquifer(in so-called attractors). From theCambridge English Corpus Starting in the late nineteenth century, farmers began using groundwater from this extensiveaquiferto supplement the highly variable surface supplies. From theCambridge English Corpus Let us assume that over a semiperiod the particles travel a small distance compared with the size of theaquifer. From theCambridge English Corpus Geothermometry and chemical and isotopic compositions can be used to assess changes inaquiferstatus during production. From theCambridge English Corpus An important example is the extraction (appropriation) of resource units from a renewable resource stock such as fish, rangelands, groundwater aquifers, or forests. From theCambridge English Corpus The topography and chaotic terrain may favor a hydrothermalaquiferas the original setting where hematite formed. From theCambridge English Corpus Under such conditions, nitrate can be leached and can contaminate the shallowaquiferwhich is also a source of drinking water. From theCambridge English Corpus Irrigators can also get ground water or contingent water rights, which can be used to fill dams or recharge aquifers. From theCambridge English Corpus These values, however, do not measure the other non-timber benefits of the forest, only its contribution toaquiferrecharge. From theCambridge English Corpus The data may suggest that growing lowland rice during the wet season could reduce the amount of nitrate leached to the shallowaquifer.
