Abstract :

The Tang Sard karstic spring with an average annual discharge of more than 1.2 m3/s is considered as one of the Khuzestan drainage karstic springs. The most flood variations in the springs are related to the rainfall time, so that from about 0.5 m3/s in response to the precipitation in November of 1395 reaches a significant increase of about 1.5 m3/s in February 1395 . The position of the emergence of a tight fountain in a broken waist of the Kenno anticline and in the direction of the crushed zone resulting from the operation of the filament faults. In order to investigate the hydrogeological characteristics of the karstic aquifer feeding the aforementioned fountains, the drainage hydrograph has been used. Analysis of the hydrograph of the Tang Sard Spring discharge in the Blue Years 95-96 indicates that a snowfall-karstic basin with a snow-rainy diet throughout the year affects the supply of springs and other hydrodynamic properties of the reservoir, somehow The effects of snow-induced feeding in the dry period are remarkable. The percentage of groundwater and fast spring springs in the year 96-95 is 64.58 and 35.42, respectively, and the total volume of dynamic storage in the year of discharge is about 38.38 × 106 m3/s (equivalent to 1.2 m3/s) Estimated. The flow regime in the karstic aquifer of springs tang sard is a conduit- diffuse.
