Abstract Karst groundwater is the main source of water supply for ecosystems that are dependent on its discharges, such as wetlands, which habitats various species. Due to their characteristics and significance, it imperative conduct research aimed at elucidating mechanisms governing quality quantity in reliant karst discharges. The karstic systems susceptible contamination, despite this fact, there a dearth information available, hampers accurate determination quality. site study system discharging RAMSAR wetland Ciénaga de Tamasopo (Mexico) affected by extraction extensive sugar cane agriculture. goal was identify flow into using hydrogeochemical isotopic techniques. Additionally, assess temporal changes physical chemical parameters. It determined composition with respect residence time subsoil, predominant processes dissolution–precipitation calcite, dolomite, gypsum water-rock interaction, mixing, evaporation. This facilitated development conceptual model understanding movement warm, sub-humid climate. crucial enhancing management strategies area.

To improve the informatization construction and intelligent decision-making level of river lake basin management, water quality a digital twin was considered as starting point evaluation platform for Chuancheng River Baihe in Nanyang City, Henan Province established. Based on technology, establishes virtual space city model, uses long short-term memory algorithm to establish prediction draws distribution pollution factors two dimensions based Kriging interpolation, simulates pollutant diffusion three numerical simulation, finally builds visual analysis. The combines with models: one-dimensional (1D) data processing, two-dimensional distribution, three-dimensional (3D) simulation achieve comprehensive management assessment. Compared traditional 1D platform, proposed 3D urban system solves problems low visualization degree, single incomplete analysis, well provides new technical guarantee quality.
