Interpretation of SP anomalies due to 2D horizontal circular cylinders is presented using the modified Hilbert transform. The modified Hilbert transform defined here is equal to the conventional Hilbert transform in magnitude but differs in phase. The additional phase associated with the modified...
The propagation of Love waves in models with local irregularities (a canyon or an alluvial valley) related to general waste deposit problems in environmental geophysics is numerically investigated. The investigation is based on a direct boundary element method for calculating wave fields and on a...
The least-squares minimization method can be used to determine the depth of a buried structure from moving average residual gravity anomalies separated from observed data using regionals of successive windows (Abdelrahman and El-Araby, 1993a). In the present study, we show that this method can be...
