Abstract |
: |
Displays the status of each of the ground water and rain in five drainage basins main Wadi Nu'man, Wadi Fatima, the valley of the Gran, Wadi Marouani, and Valley soils, located in the western region of Allofh of Saudi Arabia for a comprehensive study by means of the application of different isotopes of environmental samples of groundwater and rain collected of these areas. Furthermore Zld research also included detailed studies on the chemistry of water and climatic conditions and the mechanism of nutrition of the existing water tanks in the study area.
The impact of seasonal changes and rainfall, as well as the impact of altitude on the concentration of an environmental isotopes of rain falling on the study area can be identified has been found that the change in oxygen 18. Aldiotiram with the rise by less than -0.1 and -0.4, respectively, whenever Ertfna 100 meters above sea level.
Underground water content of oxygen-18 isotope indicates that indirect feeding of the floods that are generated in the high valleys are the main factor that groundwater recharge, on the other hand feeding the topical effect only in the upper parts of the medication.
Concentration of the radioactive isotope of hydrogen -3 (Altrtem) higher in the groundwater indicates that this water is a relatively recent range between 30 and 40 years within each of the following valleys Fatima, Numan, Marouani, and soil. While the concentration of this isotope is low and within the Grand Valley as a result of the line and that may have occurred between the date feed water ratio of the isotope was relatively higher than the old water to some extent, containing a low concentration of this isotope.
Dari marine air masses is one of the main sources of water vapor, which results in precipitation on the study area and thus lead to feed the aquifers.
Balance method using elemental chlorine, found that the feed rate varies from place to place. Within each of the Wadi Fatima, Alnama Valley, and Valley soil found that the rate was 18.1, 10.5, 7.05 mm / year, respectively. |
