The case study of the brackish spring of "Almyros of Heraklio" in Crete (Greece) and its vast carbonate coastal aquifer is presented, showing the consequence of preferential flows of continental fresh water and saline sea water in karst galleries in a coastal area. Flow heterogeneity generates unexpected upconing in boreholes, and permits the spring of Almyros not to be directly connected with ...

Abstract Climate change has a pronounced effect on water resources in many semiarid climates, causing populated areas such as San Diego County (USA), to become more vulnerable shortages the coming decades. To prepare for decreased supply, is adopting policies decrease use and develop additional local sources of water. One new source freshwater produced by desalination facility that purifies bra...

To quantify ground water denitrification in discrete locations of riparian aquifers, we modified and evaluated an in situ method based on conservative tracers and 15N-enriched nitrate. Ground water was "pushed" (i.e., injected) into a mini-piezometer and then "pulled" (i.e., extracted) from the same mini-piezometer after an incubation period. This push-pull method was applied in replicate mini-...

The influence of salinity on habitat selection and growth in juvenile American eels Anguilla rostrata captured in four rivers across eastern Canada was assessed in controlled experiments in 2011 and 2012. Glass eels were first categorized according to their salinity preferences towards fresh (FW), salt (SW) or brackish water (BW) and the growth rate of each group of elvers was subsequently moni...

There are anecdotal reports that upstream water withdrawals over the past 50 years have altered the salinity structure of coastal Georgia estuaries. Since few consistent salinity records exist, it may be possible to use shifts in vegetation to document salinity change. The purpose of this study was to use aerial photographs and GIS analysis to determine if the location of the brackish water int...

The isopod, Asellus, has been reported from a wide range of conditions in fresh and brackish water. One species, A. aquaticus, has a natural salinity range from fresh water (0-15 m-equiv./l. Na; Moon, 1957) to the Baltic (103 mM./l. NaCl; Valikangas, 1933). Thienemann (1913) has also found it occurring in Westphalian brine pools at a concentration of 25-3 % salt (equivalent to 434 mM./l. NaCl)....

A ®eld lysimeter study was conducted to investigate the effect of initial soil salinity and salinity level of brackish subirrigation water on tuber weight and tuber size of three potato (Solanum tuberosum L.) cultivars (Kennebec, Norland and Russet Burbank) under simulated arid conditions. Both saline and non-saline initial soil conditions were simulated in a total of 36 lysimeters. Eighteen ly...
