Title

Groundwater flow model of aquifer system, Kwale County, Kenya (NERC grant NE/M008894/1)

Abstract

The download .rar file contains a groundwater model of the coastal aquifer in Kwale County, Kenya (ModelMuse Text File) produced by Dr Nuria Ferrer and Dr Albert Folch at the Universitat Politècnica de Catalunya. The model can be used to explore future climate and groundwater abstraction scenarios to provide management recommendations. The download does not include proprietary abstraction data from industry project partners, thus running the model provided here will not reproduce published research findings. The file named”np67IH.bhd” are the initial heads file required to run the model.

Lineage

Model has been constructed using the MODFLOW-2005 Package and graphical interface ModelMuse (Winston, 2009). MODFLOW is a 3D code that solves the finite-difference method and includes modules to simulate steady-state or transient groundwater flow in confined/unconfined aquifers (Harbaugh, 2005). A steady-state simulation has been conducted to set up initial conditions, as compared with field data. The transient simulation covers an eight year period from 2010 to November 2017. Monthly stress periods with 3 time steps in each have been adopted in the model simulation. Further details in paper: 1-Ferrer, N., Folch, A., Lane, M. et al. (2019).
