“…In this section, we present the key components of the proposed measurement framework and the area of interest. Our previous studies [24,40,42] were focused on the River Žrnovnica, whereas here we focus on a rather more significant river in the area of Split, namely the River Jadro and its estuary ( Figure 1). A concept for the field experiment is introduced in Section 2.2 and followed by the detailed explanation of designing the probe in Section 2.3.…”

“…Three different measurement campaigns were organized during the month of July 2018 in order to test the developed prototypes and the implications for the various applications. The initial focus was to further validate the analytical model for concentration statistics in estuaries developed by Galešić et al [24] and later expanded to a spatially integrated model by Andričević and Galešić [40]. However, these particular validation procedures will be further analyzed in future work.…”

This approach has been analyzed [40,41], by measuring the salinity at different points in time with a commercial probe, the Sea-Bird's SBE 37-SI MicroCAT. Depending on the final goal of the comparison between measured and modeled data, different spatial configurations of the measured points were previously planned and executed accordingly within four measurement campaigns on the River Žrnovnica [42].…”

“…More importantly, the procedure of measurement system development (Section 2.3) and data acquisition (Sections 2.4.1-2.4.3) are described. Specific focus is given to the calculation of both velocity and salinity data, which are needed for the additional and improved validation of previous research [24,[40][41][42]. Within Section 3.1, the obtained data are shown, while final applications for obtaining the parameters needed for further modeling are displayed in Section 3.2.…”

There are multiple factors affecting the behavior of water properties in an estuary, including the hydraulic properties of rivers and corresponding receiving water bodies, along with the potential solutes brought by rivers. Although there are various numerical models and analytical approaches to solving particular or holistic problems in estuaries, measurements are inevitably required. In this study, we developed an innovative low-cost probe based on the Arduino platform as an alternative to more expensive measuring systems. Our device is designed to measure position, temperature, and electrical conductivity in multiple realizations, and it consists of a floating container equipped with the following components: an Arduino Mega development board, a power management module, an SD card logging module, a Bluetooth module, a temperature measuring module, a global positioning satellite (GPS) position module, and a newly developed module for measuring electrical conductivity (EC). We emphasize that all used tools are open-source and greatly supported by the worldwide community. We tested our probe during a field campaign conducted at the estuary of River Jadro near Split (Croatia). Nine probes were released at the river mouth and their position, temperature, and EC were monitored and recorded during the experiment, which ended when the probes stopped, due to the river plume attenuation. The same experiment was repeated three times. All of the probes recorded consistent temperature data, while the EC data show more variable behavior, due to the higher sensitivity of the corresponding sensor. This was expected as a part of the natural process in the estuary. The measured data were additionally used to parameterize an analytical model for mean flow velocity and salinity as a proxy concentration. This showed a good match between the experimental results and the theoretical framework. This work, although focused on water surface applications in the near field zone of an estuary, should be considered as a promising step toward the development of innovative and affordable measurement devices.
