Estimation of River Width with Fully-Focused SAR Altimetry Data

River width is an important indication for water storage, with the development of remote sensing techniques, estimating river width in a large area becomes possible. In this report, fully-focused SAR altimetry data with an advantage of high spatial resolution is applied to compute river width for the first time. Methodology developed based on...

The dynamic response of an embedded cavity in a half-space subjected to SH waves using the Boundary Element Method

A reciprocity-based direct boundary integral method and indirect boundary integral method have been introduced and used to obtain the two-dimensional response of a cylindrical cavity embedded in a uniform elastic half space subjected to SH wave. By introducing free wave field and the actual field with a cavity, the key point to solve for...
