Estimating the ice thickness of shallow glaciers from surface topography and mass-balance data with a shape optimization algorithm
The bedrock topography of glaciers is reconstructed with an optimal control technique. Bedrock topography and model parameters can be computed concurrently. A Tikhonov regularization based on the topography?s area is used. The whole computations underlying the algorithm are detailed.
