Once the water sharing is established, the water flows in seguias low sections to reach the secondary kasria. Shared by the secondary kasria, the water flows in small seguias to run into tertiary kasrias. Each owner then
Hydrochemical analysis and evaluation of
2012-2-28 The samples were collected in four acid-washed polypropylene containers from wells located in the El Eulma aquifer, East of Algeria (Fig. 1) after pumping for 10 min to remove stored water in the wells. Each sample was immediately filtered using 0.45 μm filters of acetate cellulose and was transferred into 100 ml polyethylene bottles.

2009-6-30 The SAR is used to classify the risks associated with sodium in irrigation water sources. Water with a SAR over 10 will accumulate sodium in the soil. High SAR can act to disperse soil aggregates, which in turn reduces the number of large pores in soil (Grattan 2002). Sodium affects the deflocculation of a clay soil, thus decreasing its no capillary porosity (air porosity) and its water
Physicochemical evolution and evaluation of
2021-2-1 It is used to estimate the amount of dissolved solids. It increases as the amount of dissolved mineral (ions) increases. It is used as a basic index to select the suitability of water for agricultural purposes (Jacintha et al. 2016). For all samples, the conductivity is between 522 and 1198 μS/cm (Table 4). In addition to the WHO standard, the results obtained are lower than the standards (2700 μs/cm) for the conductivity of drinking water.

2014-7-3 sharing water among the owners of the foggara. The portion of water depends on the contribution of each owner. From the main kasria, each part of water is fed by a channel (seguia) to a storage basin called madjen which is filled in 24 h (Fig. 5). From this madjen, the water flows in the small seguias embedded in the garden
Assessment of water quality at the largest dam in
The chemical facies of the water were chloride sulfate and calcium magnesium. The water had low levels of cadmium (8.9 μg/L) and lead (4.55 μg/L), excessive contents of chloride and bicarbonate, while pH ranged between 6.5 and 8.4. High levels of electrical conductivity were measured in 39% of samples that exceeded standard for irrigation use.

2021-7-3 Water evaporates from the surface of the land and oceans, rises and cools, condenses into rain or snow, and falls again to the surface as precipitation. The water falling on land collects in rivers and lakes, soil, and porous layers of rock, and much of it flows back into the oceans. The cycling of water in and out of the atmosphere is a
