Modeling the Karst zones in a dam site through micro-gravity data

Micro-gravity data are used in a rough terrain area to detect and model the Karst zones. A dense DTM model is used to compute terrain corrections and Bouguer gravity anomalies consequently. Residual gravity anomalies are computed by polynomial fitting method. EULDPH technique is applied to residual anomalies to get some information from the depths of anomalies. Using the depths of anomalies as A-prior information, the anomalies (Karst zones ) are modeled through inversion of micro-gravity data by Lewi’s method (Camacho et al. 2002).
