ABSTRACT: The studied subject
is about subsidence coefficient of mirages and dynamic storage volume of
Karstic springs in Khorram Abad in West of Iran. Subsidence coefficient
indicates ability of groundwater discharge and hydrologic properties of the
environment; meaning effective porosity and transfer coefficient of springs. In
general, in developed Karstic zones, each direct line of subsidence curve
indicates a discharge regime. Obtained results from the study show that
subsidence branch of Golestan, Motahari, Niloofar (changaei), Navekech, Dore
Robat mirages have subsidence coefficient with mild slope and low value, which
demonstrate passage of water through a seams system at the karst springs. Q and
whirlpool stone mirages have two subsidence coefficients, which indicate
passage of water through two seam systems in Karstic environment of springs. According
to obtained results, process of changes in subsidence branch in these mirages
has had at the first a mild slope and low discharge coefficient and in
continue, its discharge would be declined with sharper slope and high discharge
coefficient. In order to estimate dynamic storage volume of springs, MAILET
general equation is applied, which is suitable for subsidence branch of
hydrographs of centralized springs discharge. Following, dynamic storage volume
of studied springs is analyzed and obtained results are presented in this study
respectively.
