Incorporating topography
WebMay 30, 2013 · A major difficulty of electrical resistivity forward modelling is the singularity of the potential occurring at the source location. To avoid large numerical errors, the potential is split into a primary part containing the singularity and a secondary part. The primary potential is defined analytically for flat topography, and is classically ... WebJul 20, 2016 · It is found that neglecting topography with an amplitude fluctuation greater than half the minimum seismic wavelength leads to appreciable inversion image artefacts. Therefore, the incorporation of surface topography, even if it appears minor, is essential for successful elastic full waveform inversion of land seismic data.

WebJan 1, 2012 · In this study, we suggest the use of a finite difference (FD) forward solution with triangular grid to incorporate topography into the inverse solution of direct current resistivity data. A new inversion algorithm was developed that takes topography into account with finite difference and finite element forward solution by using triangular grids. WebOct 19, 2024 · The results show that rough topography allows cougars to use areas close to roads, and that the animals are less likely to avoid roads with low traffic or during night …
