Abstract :

Each karstic aquifer has its own singular hydrodynamics behavior, flow pattern and infiltration capacitycharacteristics. Recent studies have shown that the karst aquifers responses to infiltration events are veryimportant. In this research, studies reveal the effectiveness of rainfall events on the index bacterialconcentration in dry and wet period in a semi-arid region, Maharlu basin. But total rainfall does not have anydetermined relationship with total bacterial concentration in the selected karst water resources, so we need toprospect any event as unique.
