“…The predominant material in 90% of the district geological formations is carbonated, with substantial subterranean drainage. However, quaternary detrital formations predominate in the coastal plains of the area, which contributes to pollution problems due to the lower rate of transportation [36]. SW-GW interaction in the SW rivers is classified as follows: 78% receives discharges from the aquifer, considered as gaining stream; 18% are SW rivers where the river infiltrates resources into the aquifer, considered as losing; the remaining are considered as variable, where one situation or another occurs depending on the time of the year.…”

“…29(11): 863-871 doi: 10.9755/ejfa.2017.v29.i11.1496 http://www.ejfa.me/ by many researchers in an attempt to increase the water use efficiency and minimize the harmful effects of high nutrient concentrations discarded into the environment. This does take into account the scarcity of water resources, and local legislation regarding groundwater aquifers which may preexist in multiple countries (Morille et al, 2013;Ferreira et al, 2016). According to Silber et al (2003), working with lettuce planted in pots filled with perlite, the amount of drainage solution was increased, as the frequency of irrigation decreased.…”

“…Despite the revolutionary expansion of hydroponics in commercial horticulture, there are still some constrains which restrict further expansion, especially in environmentally protected areas (i.e. Nitrate Vulnerable Zones) where the discharge of drainage is not compatible under the EU Nitrate Directive (Savvas, 2002;Ferreira et al, 2016). In particular, open hydroponic cultures have considerable amounts of nutrients (i.e.…”

“…The effect of irrigation frequency, on the amount of nutrient outflow from the greenhouse, was also investigated by many researchers in an attempt to increase the water use efficiency and minimize the harmful effects of high nutrient concentrations discarded into the environment. This does take into account the scarcity of water resources, and local legislation regarding groundwater aquifers which may preexist in multiple countries (Morille et al, 2013;Ferreira et al, 2016). According to , working with lettuce planted in pots filled with perlite, the amount of drainage solution was increased, as the frequency of irrigation decreased.…”
