“…Climate change in Algeria has disrupted weather patterns such as precipitation and the water cycle, which has affected groundwater recharge and soil moisture [5]. In addition, the demand for water for various reasons is rising as a result of the expanding population [7] and increased usage of land for agriculture [8]. Furthermore, numerous types of pollution are degrading the condition of rivers in Algeria.…”

Dams are regarded as crucial pieces of structure that store water for irrigation and municipal uses. Given their vital role, the dam’s water quality assessment is considered to be an important criterion and requires constant monitoring. In this research, we attempted to use two water quality indices (WQIs) methods to assess the water quality of the Keddara Dam, which is located on the Boudouaou River, Algeria, using eleven water quality parameters (temperature, pH, conductivity, turbidity, total suspended solids (TSS), full alkalimetric title (TAC), hydrometric title (TH), nitrite ions (NO2−), nitrate ions (NO3−), ammonium ions (NH4+), and phosphate ions (PO43−)) for data recorded from 29 December 2018 to 3 June 2021. Application of The Canadian Council of Ministers of the Environment (CCME) WQIs and the Weighted Arithmetic Method (WAM) indicated that the Keddara Dam’s water quality parameters were within the WHO’s permissible level, except for the conductivity and turbidity values. The results of the CCME WQI ranged from acceptable (81.92) to excellent (95.08) quality, whereas the WAM WQI ranged from 9.52 to 17.77, indicating excellent quality. This demonstrates that the Keddara Dam is appropriate for agriculture and municipal use. The water quality indices (WQIs) methods are recommended as valuable tools that allow both the public and decision-makers to comprehend and manage the water quality of any aquatic environment by providing flexibility in choosing variables.

The present study aims to assess the impact of human activities on the water quality of Hammam Boughrara Dam, while highlighting the importance of seasonal variations of the organic pollution indicator parameters. The COD/BOD5 Ratio (CBR) values, over the period mentioned above, revealed the dominance of two categories, namely Moderately Biodegradable Effluent (MBE) and Difficult to Biodegrade Effluents (DBE) or Non-Biodegradable Effluents (NBE), with significant seasonal variations. The MBE category showed a maximum frequency in autumn (29 occurrences) and a minimum frequency in spring (20 occurrences), while the DBE or NBE category had a maximum frequency of 26 during winter and a minimum frequency of 21 during the autumn season. The analysis of Organic Pollution Index (OPI) revealed that the water of the dam under study is strongly impacted by organic pollution, with significant seasonal variations. This is confirmed by the predominance of the Organic Pollution (OP) category, with a maximum frequency in autumn and summer seasons (25 occurrences) and minimum in spring (21 occurrences), as well as by the Very Strong Organic Pollution (VSOP) category, with a maximum frequency in winter (23 occurrences) and minimum in summer (11 occurrences). The box-plot graphs showed positive skew, while others exhibited a negative one, with significant seasonal variations in the InterQuartile Range (IQR). It should also be mentioned that the correlation of the Organic Pollution Index (OPI) with the concentrations of NH₄⁺ and PO₄³⁻ ions is higher than that of the OPI with BOD5 and NO₂⁻. However, it must be recognized that the correlation between the OPI and BOD5 as well as NO₂⁻ remains significant at 1% threshold level. Moreover, the correlation coefficients showed significant seasonal variations. It is worth noting that the OPI showed a positive correlation with the dam’s water volume, during all four seasons, with correlation coefficients varying significantly for each season. On the other hand, the OPI exhibited negative correlation with COD, TDS and \({NO}_{3}^{-}\) concentrations in some seasons. In addition, positive correlations were observed between the concentrations of \({NH}_{4}^{+}\)and \({PO}_{4}^{3-}\) ions, as well as between the concentrations of \({NH}_{4}^{+}\) and \({NO}_{2}^{-}\) ions, throughout the four seasons.

“…Water is a limited resource and is under pressure from a variety of factors, including climate change, human stressors and agricultural activities. Intensification of agriculture can result in increased fertiliser use and, consequently, lead to a deterioration in water quality (Djelita, Bouzid-Lagha, & Nehar, 2016;Lutz et al, 2016). Previous research has indicated that tributaries in agricultural watersheds deliver very high sediment and nutrient losses, which are mainly determined by climatic conditions, geomorphology, geohydrology and farming practices (Z.…”

A major problem facing the water sector in Algeria is deteriorating water quality, which is strongly influenced by nutrient inputs to agricultural watersheds. To mitigate the effects of agricultural activities and enhance water quality, this study considered the impact of different best management practices (BMPs) in agriculture. The objective of the research was to evaluate the impacts of various agricultural BMPs on nitrate losses in the Sebdou catchment in north-west Africa using the Soil and Water Assessment Tool (SWAT) model in order to identify and recommend the most appropriate BMP. The study was carried out in two parts: first, the SWAT model was calibrated and validated to simulate discharge and nitrate losses at the outlet of the catchment, and second, the calibrated model was used to assess the effects of BMPs on nitrate losses. The hydrological modelling fitted well with the observed data for the calibration and validation periods (NSE between 0.63 and 0.65 and R 2 between 0.80 and 0.92). Nitrate simulation was also satisfactory (NSE = 0.58 and R 2 = 0.58), with the average nitrate exports at the outlet varying between 136 and 149 t N year À1 . Agricultural tillage practices were the main N input and plant uptake was the main N output. The simulation results of BMP scenarios (contour farming, strip cropping and terracing) showed a significant decrease in nitrate quantity in soil, nitrate yield in surface run-off and nitrate exports. The maximum reduction was observed from the use of parallel terraces, which reduced nitrate in soil by 17% (41 kg ha À1 ) and decreased nitrate flux exportation to below 133 t N year À1 (a reduction of about 11%). This study provided useful information for implementation of the most effective agricultural BMPs in the catchment for stakeholders who are interested in soil and water management.
