This is a study in the area of microclimate and aeolian processes causing weathering of the Globigerina limestone of the Ħaġar Qim and Mnajdra Temples. It is expected that since the shelter recently erected to protect the temples from the elements might be causing a convergence of wind streamlines and the consequent lowering of the air pressure, an increased wind velocity may result just under the shelter causing enhanced wind erosion on the temples. In this study, we will look at whether and how the protective canopies have actually enhanced wind funneling and therefore increased temple deterioration because of increasing wind velocities. Turbulent, laminar wind-flows and eddy-currents will be analyzed so as to identify particular sites which are particularly prone to wind erosion especially abrasion. Microclimate data collected by the Preventive Conservation Unit of Heritage Malta will be used as baseline results so as to compare wind velocities inside and outside the shelter. This will be complemented by wind data collected in different parts of the temple by anemometers so as to identify variations in wind speed in different parts of the area. Additional information will be provided through sticky pad sampling, used to collect dust in saltation and suspension both inside and outside the shelter and temple. From the investigations carried out it has been found that, contrary to prior expectations, no significant wind funneling occurs as wind enters from underneath the canopy and moves through the megalithic structure. Thus not only is the shelter responsible for decreased wind velocities but funneling does not occur except through particularly tight channels through some of the megaliths. Consequently, strategies aimed at preventing the remaining funneling and abrasion, such as the adjustable wind shields and the planting of protective vegetation, are proposed.
