Geochemical and Isotopic Evidence of Groundwater Salinization Processes in El Dabaa Area, Northwestern Coast, Egypt

open access: yesGeosciences, 2018
El Dabaa city is located along the northwestern coast ridge zone of Egypt, where the groundwater is the major water source for drinking, domestic, and agricultural purposes. The groundwater salinity increased over the last decades, therefore, geochemical

DILSTORE software for ecological status assessment of lakes based on benthic diatoms [PDF]

open access: yes, 2009
Until recently, only few diatom indices were developed for monitoring littoral zones of lakes. The available indices are not applicable for all lake types because species lists and environmental constraints’ ranges are different.
