Sensitivity Analysis on the Modeling of Flows and Heat Transfers in the Geothermal Field of Basse-Terre, Guadeloupe

Numerical modeling of the geothermal hydrology of the Volcanic Island of Basse-Terre, Guadeloupe

“…Establishing such parametrization is challenging, both in terms of the initial choice of parameters to describe the system at the appropriate scale and in uncertainty management of parameter values. We ran a preliminary study to assess the sensitivity to the topography, the precipitation flux and geological heterogeneities (Raguenel et al 2017). This work showed that topography needs to be carefully represented, but that the infiltration from rainfall has a limited impact on the simulation for this area.…”

“…On the bottom of the model, a basal heat flux is represented with a value of 100 mW/m 2 (Manga et al 2012). On the top of the model, we decided to maintain the initial conditions at atmospheric pressure and temperature as the precipitation flux has a negligible impact on the simulation (Raguenel et al 2017). The lateral boundaries of the model are free flow boundaries.…”
