NECoM (Numerically Enhanced COnceptual Modelling) of two small Maltese Aquifers: Mizieb and Pwales

Abstract

Two small Maltese aquifers, Mizieb and Pwales, were numerically analyzed to test the existing hydrogeological conceptual model and suggest optimized groundwater monitoring strategies in support of the forthcoming monitoring network coordinated by the Government of Malta through the Energy and Water Agency. The model will undergo further revision of the concepts on which it is based as soon as new data is available, considering the conceptual and numerical model development as parallel activities, rather than as sequential. The model structure and parameter estimation made use of qualitative information and data acquired by archive research; during model calibration information/assumptions were introduced as “prior information” while the available measurements were introduced as classical “observations” with proper associated weight. The information content of both qualitative and quantitative data could be assimilated along the calibration process, highlighting the uncertainties and open questions that remain because of data insufficiency.

Modeling groundwater/surface-water interactions and their effects on hydraulic barriers, the case of the industrial area of Mantua (Italy)

“…• StreamFlow Routing (SFR2) to simulate, through 19 segments, the streamflow along the main channels of the hydrographic network, calculating the exchange between the surface and groundwater systems. An analysis of all the available project schemes was conducted to define the best conductance values of channels/rivers, e.g., structure, geometry, materials (Lotti et al 2021). • Well (WEL) to model the 229 wells and hydraulic barriers within the SIN.…”
