“…Analyzing the uncertainty of the mechanism of the model, for the simulation of inland lakes, WRF-Lake uses the assumption of a single-column model. In recent years, models have been developed that directly simulate the turbulent exchange in the water column, and even models with more accurate physical mechanisms that directly solve the 3D flow field [72,73] have been developed. Moreover, from the point of view of the uncertainty in the observed data, the heat storage was calculated using the assumption of energy closure in the observed data used in this paper.…”

Lake Taihu, a typical shallow lake in eastern China, was selected for study in this paper. Methods: Considering that the accurate parameterization scheme is the key to a lake breeze simulation, then based on Lake Taihu’s characteristics, the setting of parameters of the lakes’ scheme was adjusted in the WRF (Weather Research and Forecasting Model) lake model. Results: By comparing the observed values of the mesoscale flux platform of Lake Taihu from June to August 2012, the results showed that the model significantly improved the simulation. The root-mean-square error of the simulated and observed comparison of the latent heat fluxes over the lake improved from 42.77 to 89.00. The adjusted WRF-Lake model better presents the characteristics of Lake Taihu’s lake wind. The different lake depth cases showed that the maximum difference in surface temperature between the shallow lake case and the deep lake case reached 9.9 °C, and the average was about 3 °C. Conclusion: Compared with the deep lake case, the shallow lake case stimulated less lake breeze circulation with a shorter time and smaller range in the horizontal and vertical directions. The lake breeze frequency, simulated by the shallow lake case, was 18.5%, while for the deep lake case, it reached 38%. These simulations of lake breeze contribute to understanding the influence of a lake’s depth on lake breeze characteristics and the accurate parameterization scheme of the inland shallow lakes.

“…The Q1 of January-March, June-July, and November in the study area was 3, indicating that only 25% of the stations had a low frequency of rising events during approximately half the year. The lowest value of the frequency of rising events each month was 1, whereas the highest value varied widely, with the highest in August (20) and the lowest in February (12). The outliers of the frequency of rising events were mainly concentrated from July to September.…”

“…The resulting ecological and environmental effects have also become more prominent. The dynamic changes of groundwater have been studied using macro devices, including remote sensing and satellite data in the literature [12][13][14]. However, the problem of AGLR in the PLB urgently needs to be solved [15] and has not been systemically studied yet.…”

Studies on groundwater have traditionally been based on declining groundwater levels and associated ecological, environmental, and geological problems. However, due to extreme hydrometeorological events and human activities, rising groundwater levels have been observed in many areas. The daily groundwater levels from 2018 to 2020 for the Poyang Lake Basin (PLB) in Jiangxi Province were recorded. The statistical characteristics of abnormal groundwater level rising (AGLR) events and the factors influencing the dynamic changes in groundwater level were analyzed using geostatistical methods and outlier identification methods. The groundwater level in the lower terrain of the PLB has increased significantly in recent years. AGLR events identified by the median absolute deviation and interquartile range methods showed that AGLR events mainly occurred in the spring and summer and were mainly distributed near the surface water bodies. Correlation analysis of the factors influencing the groundwater level revealed that the correlation between precipitation and groundwater level was related to topography. In contrast, the correlation between river stage and groundwater level was related to runoff volume.

“…These techniques are commonly used in water quality assessment to useful information from water quality data matrices and avoid misinterpretation of large complex monitoring. One application of multivariate statistics in water quality assessment is the analysis of remote sensing, landsat data and satellite data [4,5]. Multivariate statistical techniques such as cluster analysis and principal component analysis can be used to analyze these data sets and identify patterns or trends in water quality over time and space [6].…”

The study evaluates the surface water quality of the Bach Dang river basin. During the rainy season, the temperature, pH, EC, BOD5, COD, coliforms, ammonium and phosphate values were 27–37 oC, 6.6–8.9, 300–2200 μS/cm, 5–25 mg/L, 5–26 mg/L, 0–3000 MPN/100mL, below 0.01 mg/L, and 0.02 mg/L, respective. During the rainy and dry seasons, Zn, Pb, Cr, As, Fe and Mn levels were below drinking water limits. In the rainy season, the water quality index varied from 76 to 91, signifying medium to excellent water quality. The most outstanding water quality sites were the QN12, QN18, and QN22. During the dry season, most areas had moderate to excellent (WQI values between 61 and 93), except for QN01, QN03, QN04, QN05, QN06, QN07, QN11, QN16, QN17, QN19, and QN23, where it dropped to moderate (61–73). The temperatures were greater and higher EC values in the southeast. The DO concentrations were higher in the northwest and southeast in both seasons. The southern and southeastern regions exhibited more excellent COD and BOD5 values than the western, southwest, north, and northeast regions. The ammonium concentrations were higher in the southeast. During the dry season, the phosphate levels exceeded the permissible limit in the west, southeast, east, and northeast. Coliforms were below acceptable in both seasons, with greater levels in the northwest and northeast during the dry season. In addition, the Zn and Pb are favorably associated with the As, Mn, ammonium and phosphate in the rainy season. The COD positively correlated with the coliforms and BOD5. In the dry season, the pH inversely correlated with the Pb and Fe positively. The ammonium correlated negatively with the DO and positively with the phosphates. The pH negatively connected with the alkalinity, while the As positively correlated with the BOD5 and COD.
