“…However, due to the growing water demand, real estate speculation, and fishing activities in this ecosystem, this scenario may change and lead to the degradation of its water, thus implying the need for constant monitoring strategies for the proper management of water and correct decision-making (Ziemińska-Stolarska et al, 2019).…”

Aim Humid forest enclaves are areas with privileged rainfall patterns compared to the surrounding regions, which favours their use for human settlement and agricultural activities, actions that promote severe transformations of the landscape and can contribute to the degradation of local water resources. From this perspective, given the great importance of water reservoirs for this region and the high demand for water, this study aimed to analyse the conservation status of water quality in reservoirs subjected to different anthropic disturbance in a humid forest enclave in the State of Paraíba, Brazil. Methods Sampling campaigns were carried out for one year in six reservoirs: Mazagão I, Mazagão II, Vaca Brava, Saulo Maia, Rio do Canto and Lagoa do Paó, to measure the physic-chemical variables of the water. Results The influence of annual rainfall patterns on the capacity of these ecosystems to respond to anthropic pressures, indicating the effects of seasonality in the Lagoa do Paó reservoir. For the Vaca Brava, the low accumulated water volumes turned out to be more critical for changes in water quality than the use and occupation of the margins of this reservoir. Furthermore, the Mazagão I and II reservoirs showed low electrical conductivity. The Saulo Maia reservoir exhibit clear waters with low phosphorus content and can be used as a reference for a preserved environment for a highland humid forest enclave. Conclusions The conservation of the reservoir environment in the highland humid forest enclave is not sufficient to guarantee the water quality, as it is concentrated an affected at a certain time of the year. These aquatic ecosystems are under great pressure and the lack of decisions based on technical criteria makes them vulnerable to eutrophication.

“…The flow of water in the Luciąża is in the range of 0.8 to 9.2 m 3 /s, with an average annual flow of 1.91 m 3 /s [57]. The results of studies on water quality in the reservoir confirm significant loading with biogenic compounds from both Pilica and Luciaza rivers [62][63][64][65].…”

The aim of this work is to evaluate core variables of the ecological potential of the Sulejów Reservoir (temperature distribution, flow velocities, and concentrations of selected indicators, e.g., phosphates, nitrates, the abundance of phytoplankton) using a three-dimensional hydrodynamic model, GEMSS-HDM (generalized environmental modeling system for surface waters), coupled with a water quality model, WASP EUTRO (GEMSS-WQM). The monitoring data necessary to build the model were obtained from two multiparameter probes that were submerged in two locations in the Sulejów Reservoir. An ADCP current profiler was used to collect data for hydrodynamic model calibration and verification. Total error between computed and measured velocity was estimated at 10–15%. A high concentration of chlorophyll-a during the vegetation season of 2015 (0.02 mg/L) was coupled with high water temperature (above 25 °C) and low concentrations of biogenic compounds (phosphorus and nitrogen at 0.02 and 0.001 mg/L, respectively). In 2015, NO3-N was the limiting nutrient in the Sulejów Reservoir. Maximum growth of algae was observed in June and July 2015 (0.02 mg/L chla) along the entire length of the reservoir; algae bloom volume reduction was observed in September (0.004 mg/L chla). Proposed scenarios for nutrient reduction—50% reduction of phosphate-phosphorus (PO4-P) and nitrate-nitrogen (NO3-N) from agriculture areas as well as 50% reduction of discharges from septic tanks—led to a considerable reduction of nutrient concentrations in the reservoir waters; it additionally favors reducing the concentration of chlorophyll-a. The obtained results indicate that these sources of pollutants are mainly responsible for the poor water quality status of the reservoir and more intensive eutrophication phenomena.

“…In addition, previous studies conducted in the field have demonstrated strong correlations between sensor data and cell counts in single phytoplankton assemblages: Planktothrix rubescens, r = 0.899, n = 110 [44]; Fragilaria crotonensis, r 2 = 0.70, n = 25 [45]; and Ceratium sp., r = 0.984, n = 19 [46]. Ziemi ńska-Stolarska et al [47] examined a dataset of 650-700 data points, of which only 30 were analyzed in the laboratory. Consequently, obtaining sensor data via conventional laboratory analysis methods (e.g., microscopy) is limited and inefficient in terms of analyses, expenses, and time.…”

There are physical, chemical, and biological methods to control algae, and their efficiency requires evaluation. In the field, monitoring and evaluating the overall algal concentration is challenging due to factors such as the flow rate, inhomogeneous distribution of algae in the water body, and limitations in the number of samples for microscopic analysis. In this study, we analyzed total and cyanobacterial chlorophyll a (Chl-a) using a FluoroProbe sensor and microscopic data collected from March to November 2019. The Pearson correlation coefficient of log(x + 1) values revealed a significant positive correlation between four harmful cyanobacteria and cyanobacterial Chl-a (r = 0.618, p < 0.01). Furthermore, we explored the potential of evaluating the efficiency of algal control using sensors by acquiring three-dimensional, spatially continuous data for an algal fence, a physical algae control technology installed at the Daecheong Dam in 2021. The results confirmed that sensors can effectively evaluate algal control technology. This study demonstrates the effectiveness of using sensors to assess the efficiency of physical algal control.
