Abstract (11 Views)
Aims and Background: Using water potential and existing elements, groundwater can be estimated as the basis for these changes and developments. The purpose of determining the groundwater (boundary) conditions relative to seawater. Therefore, an attempt was made to determine this boundary by considering the elements and factors.
Methodology: With the help of elements that influence concentration increase, along with Herzberg and Warwich empirical relationships, the maximum advance of seawater towards the coastal aquifers of Gilan and the salinity line is determined.
Findings: On the other hand, the influencing elements have increased the concentration in the groundwater aquifers and the density of seawater in the triangular section has become almost equal to the density of coastal groundwater The common boundary between salt and fresh water advances towards the coasts. General map was obtained from the combination of all the maps Which defines the current situation (border).
Conclusion: As a result, the largest area is related to the element chlorine, and the highest concentration of groundwater and elements in all maps from the center to the east of Gilan, and the highest harvest in this region is in the summer. The highest salinity is around Chamkhale to Chaf, and the salinity decreases from the coast towards the mountains. The general map of the influencing elements shows that the salinity line completely coincides with the triangle. The overall map of influencing elements shows that the salinity line completely coincides with the triangle.
