“…In aquatic ecosystems, the DO level is a critical water quality indicator and its variation is related to photosynthesis (Parween et al, 2022). The DO is also a value of the ecological status of the river (Ding et al, 2017). Aerobic microorganisms, present in contaminated water, degrade organic matter and reduce the dissolved oxygen content (Kükrer & Mutlu, 2019).…”

Water quality in rivers is affected as it passes through urban areas; this situation can be improved with good management of water resources. High Andean rivers require further studies to indicate their quality status. In addition, it is important to estimate the health risks associated with exposure to contaminants in the river water. Therefore, it is proposed to assess the water quality index (WQI) using the National Sanitation Foundation (NSF) model and the health risks in the urban section of the Ichu River in Peru. Six monitoring points were selected in the section of the Ichu River that includes the urbanized part of the city of Huancavelica. The sample was taken during the months of February to April 2021. Critical parameters were analyzed by multivariate statistical analysis as principal components and cluster test. In addition, Pearson's correlation test was performed, and the water quality status was evaluated using the WQI-NSF model. The Ichu River was of "bad" quality, unfit for human consumption, and confirming the impact of the population on water quality. The WQI-NSF model could be useful for high Andean watercourses suffering from anthropogenic deterioration of quality, with illegal effluent discharges and poor sanitation. There is a high health risk due to fecal coliform contamination from sewage discharges into the river. In addition, the total hazard index indicated that contaminants are causing negative health effects in adult males at a low risk level (risk 2), adult females at a moderate risk level (risk 3), and children at a negligible risk level (risk 1). With the help of this study, an appropriate management plan can be put in place to restore the ecological integrity of the Ichu River.

“…The DO is essential in water quality and the ecological health of aquatic ecosystems. Besides, during photosynthesis the oxygen produced in aquatic environments facilitates oxygen saturation [Ding et al, 2017]. However, a low value was found in MP-6 mainly, this refers to the anthropic activity that supports the river in its downstream course, accompanied by discharges of wastewater from various sources that increase microbial activity and accelerate organic matter degradation resulting in oxygen reduction in the river water.…”

In developing countries, river monitoring is very limited. Despite environmental and health problems, there is a paucity of information regarding the contaminants phosphates and nitrates. Thus, concentration and health risks, of phosphates and nitrates of the Ichu river waters, in Huancavelica, Peru, were evaluated. Sampling was carried out at six different points. Important water quality parameters were analyzed, such as pH, temperature, dissolved oxygen (DO) and electric conductivity (EC). The results revealed that the phosphate and nitrate varied between 0.475 to 0.575 mg/L and 11.10 to 14.00 mg/L, respectively. The concentration of phosphates and nitrates was 0.520±0.02 mg/L and 13.10±0.48, respectively. The Ichu River water had the quality that corresponded to its category, when compared to the permitted limits of the Environmental Quality Standards (EQS) for water. It did not present contamination according to the nutrient contamination index and the health risk was from chronic low intake. Besides, it presented a moderate relationship between nitrate and phosphate, due to the low concentration of phosphates during the dry season. What is new about this research is the approach to potential health risks of exposure to nitrates and phosphates, in a high Andean river in Huancavelica, Peru.

“…After statistically analyzing the data, linear multivariate regression was created. Eventually, the equation with the lowest standard error and greatest correlation was considered the final one: (1) …where E = evaporation (mm), T = temperature (centigrade), W = wind speed (m/s), and M = relative moisture.…”

Evaporation from reservoirs is an important issue frequently occurring in dry, hot regions like Iran. Since the laboratory and field studies of evaporation control are difficult, time-consuming, and costly, and the investigation of various possible modes is not possible, numerical models with high capabilities are widely used to analyze the hydrological processes. This article aimed to investigate the effect of windbreaks on reducing evaporation of lakes and reservoirs in dry areas and determine the most optimal location and layout of windbreaks using the FLUENT model. Initial investigations showed that wind is the most important factor of evaporation in the Chahnimeh Region of Sistan, Iran. The results showed that if solid windbreaks with 25% casement (height of 2 and distance of 66 m) are vertically installed in a northwesterly direction, evaporation can be effectively reduced. Although the use of wind breaks in Chahnimeh can help significantly reduce evaporation, it cannot be fully controlled. That is why diagonal windbreaks with 30, 45, and 60º were designed to integrate the windbreaks with other evaporation control methods such as solar panels. The results showed that 60º had the greatest amount of evaporation reduction and were integrated with other methods to control evaporation.
