Various hydrogeological problems like groundwater inflow, water table drawdown, and pressure redistribution may be encountered in the construction of hydraulic projects. How to accurately predict occurrence inflow assess drainage effect during are still challenging for engineering designers. Taking Jinzhai pumped storage power station (JPSPS) China as an example, this paper aims use different methods calculate rates underground powerhouse evaluate caused by tunnel construction. The consist analytical formulas, site rating (SGR) method, Signorini type variational inequality formulation. results show that considering stable overestimate caverns drained conditions, whereas SGR method with available hydro-geological parameters obtains a qualitative hazard assessment preliminary phase. numerical solutions provide more precise reliable values complex geological structures seepage control measures. Moreover, effects, including seepage-free surface, pore redistribution, gradient, have been evaluated using various synthetic cases. Specifically, faults intersecting on significantly change flow regime around caverns. This comparative study can not only exactly identify capabilities cavern but also comprehensively

Crop diseases pose a significant threat to global food security, with both economic and environmental consequences. Early accurate detection is essential for timely intervention sustainable farming. This paper presents review of machine learning (ML) deep (DL) techniques crop disease diagnosis, focusing on Support Vector Machines (SVMs), Random Forest (RF), k-Nearest Neighbors (KNNs), models like VGG16, ResNet50, DenseNet121. The method includes an in-depth analysis algorithm performance using key metrics such as accuracy, precision, recall, F1 score across various datasets. We also highlight the data imbalances in commonly used datasets, particularly PlantVillage, discuss challenges posed by these imbalances. research highlights critical insights regarding ML DL detection. A primary challenge identified imbalance PlantVillage dataset, high number healthy images strong bias toward certain categories fungi, leaving other mites molds underrepresented. complicates model generalization, indicating need preprocessing steps enhance performance. study shows that combining Vision Transformers (ViTs) Green Chromatic Coordinates hybridizing SVM achieves classification emphasizing value advanced feature extraction improving efficacy. In terms comparative performance, architectures convolutional neural network demonstrated robust accuracy (95–99%) diverse underscoring their effectiveness managing complex image data. Additionally, traditional exhibited varied strengths; instance, performed better balanced while RF excelled imbalanced Preprocessing methods K-means clustering, Fuzzy C-Means, PCA, along ensemble approaches, further improved accuracy. Lastly, underscores high-quality, well-labeled stakeholder involvement, comprehensive evaluation precision are crucial optimizing models, making them more effective real-world applications agriculture.

The lakes known as El Sol and La Luna are high mountain water deposits located in Mexico within an inactive volcanic system. These of ecological importance because they unique Mexico. However, currently, the have experienced changes their shape increase algae blooms, coupled with degradation basin, which has alerted government entities to need address lakes’ problems. To environmental status Luna, a trophic study was conducted during period 2021–2023, including analysis influence climatic variables, lake quality, eutrophication conditions. state established based on index. Pearson correlations defined interrelation between distinct factors influencing status. registered higher conditions than Luna. identified seasonal eutrophic transitioning from oligotrophic mesotrophic, showing levels chlorophyll, total phosphorus, nitrogen low transparency. principal altering were pollution variables (precipitation ambient temperature).

The Chi and Mun River Basins, the primary tributary of Mekong Basin in Thailand, is undergoing significant land use changes that impact water quality. Understanding relationship between quality crucial for effective river basin management, providing insights applicable to global systems. While past studies have examined Basin, research specifically focusing on Chi-Mun remains limited. This study analyzes spatial temporal effects from 2007 2021 using change estimation, 11 parameters, redundancy analysis (RDA). Water samples were collected January, March, May, August across multiple years. Seasonal variations assessed, with dry season January March wet May August. Key findings include: (1) pH, Biochemical Oxygen Demand, Total Coliform Bacteria, Fecal Phosphorus, Nitrate Nitrogen, Ammonia-Nitrogen, Suspended Solids increased during season, while (2) Dissolved Oxygen, Electrical Conductivity, Quality Index higher season. (3) Land had a greater driven by runoff expanding urban agricultural areas declining paddy forest cover. (4) Forests aquatic improved quality, expansion contributed its deterioration. These underscore need sustainable management strategies balance regional development ecological conservation Basin.
