Special Issue Information

Dear Colleagues,

Human activities, particularly in regions experiencing the development of industry and agriculture and the exploitation of mineral resources, pose increasing threats to terrestrial ecosystems and groundwater environments. This situation is critical in areas facing water scarcity, where groundwater serves as the primary source of drinking water. Such concerns center around the type, distribution, source, migration, transformation, and ecological health risks associated with various contaminants in soil–groundwater ecosystems. The concentrations of contaminants in these ecosystems are complex due to long-term water–rock interactions, diverse groundwater recharge patterns, hydrological–biogeochemical processes, and intensive human exploitation. Notably, the threat extends to both traditional and emerging inorganic and organic pollutants, which find their way into human bodies via bioaccumulation, food chains, and drinking water, thus leading to health risks such as chemical toxicity, radiation exposure, and carcinogenic effects. In the face of escalating environmental challenges and the urgent need for sustainable land management, the assessment of soil quality and resources has never been more crucial. Given the pivotal role that soil and groundwater play in supporting agriculture, maintaining natural landscapes, extracting geothermal resources, and providing potable water, it is imperative that we deepen our understanding of these resources.

In response to these environmental challenges, we have established a Special Issue entitled “Soil and Groundwater Quality and Resources Assessment, 2nd Edition”. This collection of research articles aims to illuminate the critical processes at play and promote innovative approaches that protect our soil and groundwater ecosystems.

With the frequent occurrence of extreme weather events worldwide, the compound frequency of drought and flood events has significantly increased, imposing multidimensional pressures on agricultural water resource management. Agricultural water consumption accounts for approximately 70%, with severe waste, as a large amount of water is lost during transmission and distribution. Faced with increasingly severe and frequent extreme weather, traditional drainage systems may become unsustainable. Identifying the factors influencing drainage time is crucial for efficient drainage. The MIKE URBAN model has significant potential in farmland waterlogging simulation and drainage network optimization. This study validated the model’s accuracy based on infiltration well overflow capacity experiments, with Average Relative Error (ARE) values of 2.29%, 6.52%, 4.41%, 3.17%, 4.37%, and 5.69%, demonstrating good simulation accuracy. The MIKE URBAN model was used to simulate drainage networks, explore factors affecting drainage time, establish an annual cost system for the drainage network, and optimize the network using a genetic algorithm with the objective of minimizing annual costs. Research findings: There is a clear negative correlation between the maximum inflow of infiltration wells and drainage time. As inflow increases, drainage becomes faster, but beyond 0.0075 m3/s (27 m3/h), the efficiency gains level off. This indicates that selecting infiltration wells with at least a 20% opening ratio is essential. Similarly, increasing the collector’s diameter enhances drainage efficiency significantly, though the effect follows a diminishing return pattern. While smaller lateral spacing improves local water collection, it may lead to flow congestion if the collector is undersized; conversely, larger spacing increases drainage paths and delays, even if the collector is large. An optimal spacing range of 100–150 m is suggested alongside the collector diameter. Lateral diameter also affects performance: increasing it reduces drainage time, but the benefit plateaus around 200 mm, making further enlargement cost-ineffective. The genetic algorithm helped to optimize the drainage network design. Utilizing the genetic algorithm, the drainage network was optimized in just 15 iterations. The fitness function value rapidly decreased from 351,000 CNY to 55,000 CNY and then stabilized, reducing the annual cost from 59,640.67 CNY to 45,337.86 CNY—a 24% savings—highlighting the approach’s effectiveness in designing efficient and economical farmland drainage systems. This study has shown that the simulation-based optimization of drainage networks provides a more rational and cost-effective approach to planning drainage infrastructure. Full article
