Model Instance Title:
Chilgrove House
Model Instance Short Name:
Chilgrove House
Description:
Lumped, conceptual groundwater models can be used to simulate groundwater level time-series quickly and efficiently without the need for comprehensive modelling expertise. A new model of this type, AquiMod, is presented for simulating groundwater level time-series in unconfined aquifers. Its modular design enables users to implement different model structures to gain understanding about controls on aquifer storage and discharge. An AquiMod model has been produced to simulate the groundwater level response at the Chilgrove House (CH) OBH. The CH OBH was chosen for its long record and is used to illustrate how AquiMod can be applied to the chalk aquifer. The majority of model parameters demonstrate sensitivity and can be related to available field data. The model structure experiments demonstrate the need to represent vertical aquifer heterogeneity to capture the storage-discharge dynamics efficiently
