ABSTRACT:

This resource contains input files for SUTRA simulations used to replicate the conceptual model of the Kuparuk aufeis field developed by Terry et al. (2020) and to investigate the sensitivity of the aufeis volume of various parameters. The results of the simulations are presented and discussed in Lainis, A., Neupauer, R.M., Koch, J.C., and Gooseff, M.N. (2024).

ABSTRACT:

Sensitivity analysis requires the calculation of the sensitivity of a performance measure of model output to a model input. This repository contains two jupyter notebooks demonstrating the calculation of forward (using Green's functions) and adjoint sensitivities. Both examples are presented in

Neupauer, R.M., C. Turnadge, and J. Okkonen, Forward and adjoint modeling of sensitivities to periodic forcings in groundwater flow and transport, Mathematical Geosciences, http://dx.doi.org/10.1007/s11004-023-10074-w, 2023

Case 1 is a periodic thermal loading in a one-dimensional, homogeneous aquifer. Case 2 is stream depletion in a two-dimensional homogeneous aquifer.
