In dam site studies, the study of permeability and joints and hydrogeomechanical behavior is
one of the basic requirements of the exploration stages. Due to the complexity of geological
conditions, measurements of hydrogeological data such as hydraulic conductivity and
conductivity may indicate significant uncertainty. Accordingly, estimation and simulation of
hydrogeological data are performed by different methods. Geostatistical methods have been
widely used for estimating aquifer hydraulic parameters and investigating the uncertainty of …

Tangab Dam is located 90 km south of Shiraz city and 12 km northwest of Firuzabad city on
the Firuzabad river. This dam is constructed in the Zagros zone on the Podenow limestone
anticline. Evidence shows that there is a possibility of water escaping from the reservoir and
abutments. In this research, the exploratory data analysis includes: distribution maps,
histogram, statistical parameters, and variogram was performed on the variables of RQD,
Lugeon and cementing. Moreover, geostatistical modeling is used to recognize the …
