This study focuses on identifying GW-SW interaction locations in a tropical lake - Vellayani Lake (VL), Southwest India, utilizing stable water isotopes (s18O, sD) and chloride mass balance approach. The northern region was identified as critical groundwater discharge “hotspot” with pronounced (2.14×106 3.82×106 m³/yr), prompting targeted management interventions. reaffirms the role of inflow sustaining lake’s balance. Additionally, application machine learning (ML) techniques refined classification Lacustrine Groundwater Discharge (LGD) non-LGD sites while predictive modeling Sensitivity Indices enhanced understanding prominent factors influencing volume. K-means clustering Random Forest (RF) classification, achieved high accuracy (90%) kappa value 0.8 distinguishing non-discharge sites. Predictive sensitivity analysis revealed precipitation most influential factor, ±20% change causing 16.69% variation exhibited index 0.5320, further emphasizing its maintaining hydrological integrated approach provided valuable insights into nearshore recharge facilitates identification suitable areas for structures. For practitioners policymakers, this offers robust framework zones, prioritizing areas, designing sustainable strategies, especially data-scarce regions, paving way improved resource similar environments.

A Potential Technology for Improving the Quality of Lake Water Environments in Cold Zones: A Case Study from Lake Hulun, China

Sustainability, Год журнала: 2024, Номер 16(23), С. 10746 - 10746

Опубликована: Дек. 7, 2024

Lakes in cold zones have common characteristics of long frozen periods and fragile water ecosystems. More more lakes been experiencing quality deterioration due to eutrophication with climate change human activities. Lake Hulun is located the zone northern China, which Cyanobacterial blooms frequently occur. The excessive nutrient input inflowing river lake hydrodynamic condition might be main factors affecting this. To obtain a better understanding effects, loads nutrients from rivers were analyzed. A field test freezing concentration combined microbial activity regulation was carried out at river–lake confluence. results showed following: (1) receives large amount nitrogen phosphorus pollutants runoff every year, these inferior Grade V, greatly increases difficulty ecological purification lakes. (2) control technology has high rate for during unfrozen period. order rates each hydrochemical index TP > TN COD NH4+-N, between 35% 36%. Compared before purification, grade improved V III. (3) composite concentration–microbial general Under low-temperature condition, fluxes reduced by 9.38% 9.36%, respectively. After ice body above II, under layer IV, one higher than original water. This treatment process green, low-energy consumption, low-cost technology. study can provide reference integration demonstration governance resources security arid regions. It beneficial sustainable development lake.
