Gradient-based estimation of Manning's friction coefficient from noisy data
Victor M. Calo, Nathan Collier, Matthias Gehre +2
We study the numerical recovery of Manning's roughness coefficient for the diffusive wave approximation of the shallow water equation. We describe a conjugate gradient method for t…
