“…Once equilibrium is reached, carbonate will not precipitate further (Figure 2a‐IX) (Andrews, 2006; Bono et al, 2001) unless the water temperature increases (Baatz, 1978; Dreybrodt, 1982); the CO 2 level is brought below that of the atmosphere, for example, if cyanobacteria (Merz, 1992; Spiro & Pentecost, 1991), algae (McConnaughey, 1991) or higher plants grow in the water and extract CO 2 ; or if evaporation reduces the water volume (Figure 2a‐X,XI) (Curie & Petit, 2014; Harmon et al, 1983). Such conditions exist on the outside of channels in leakage water (Figures 2‐X,XI and 3d) (Sürmelihindi & Passchier, 2013) or in a channel if it is an open system or if the vault is damaged (Figure 2a‐X,XI) (Sürmelihindi, Passchier, Baykan, et al, 2013).…”

Calcium carbonate deposits from ancient water systems such as aqueducts are a hidden archive for archaeology and environmental sciences. These deposits formed wherever carbonate‐rich water was in contact with a water‐containing structure and recorded water composition, temperature, biological content, the operation or nonoperation of a water system segment, flow discharge and velocity, the shape of disappeared segments of water structures, the number of years a water supply system was active, disruptions of the water supply and water management such as repairs, adaptations and cleaning. Indirectly, urban development, resilience, population‐ and socioeconomic dynamics can be studied through the stratigraphy of carbonate in water systems. Carbonate archives can also give insight into long‐term changes in paleoclimate and on environmental pollution, deforestation, extreme floods, droughts, earthquakes and volcanic eruptions. Archaeological and environmental investigations of carbonate deposits can provide data with up to daily resolution over decades to centuries. Although absolute dating of carbonate from water systems is still problematic, each study on the aqueduct of an ancient city, together with its carbonate deposits, provides its own microstory in Roman life.

Accurate determination of the tufa growth rate (TGR) is required to answer the fundamental geomorphological question of tufa evolution. The TGR has been measured by various direct and indirect methods. One of the most popular direct methods uses modified micro‐erosion meter (MEM), which has several drawbacks.Here, we present for the first time a coordinate measuring macro‐photogrammetry device (CMD) for monitoring the TGR in a contactless manner. The CMD was applied on 28 limestone plates at 14 locations within the Skradinski buk area, Croatia, and measurements were performed in the laboratory. The TGR was derived from digital tufa high‐resolution models (DTHRMs). The accuracy of the device was evaluated using state‐of‐the‐art three‐dimensional (3D) scanners and error calculation at checkpoints. Moreover, the precision was evaluated with the split test (n = 5).A total of 74 DTHRMs with a spatial resolution of 0.0236 mm were created. The TGR ranged from 0.327 to 19.302 mm a−1, with an average of 5.771 mm a−1. A higher TGR was observed on the limestone plates near mosses, located in fast and turbulent water rather than in stagnant water. We found that specific micro‐environmental factors (e.g. proximity to moss) positively affected tufa growth. Erosion events were observed, as well as the presence of aquatic insect larvae (Simuliidae and Chironomidae), which positively affected tufa growth.The CMD is a precise and accurate device that does not suffer from the drawbacks of the MEM method and has many other advantages. It has a high capability of tufa erosion detection, enables the identification of macroinvertebrates, and multispectral or hyperspectral cameras can be mounted on the device for spectral reflectance analysis of the tufa surface.The CMD can be applied in any study requiring a sub‐millimetre data quality and involving the comparison of consecutive 3D models and derivation of various parameters of smaller objects. © 2020 John Wiley & Sons, Ltd.
