“…Cherkasov et al (2018) proposed that longterm monitoring could be accomplished by high-precision repeated UAV surveys. Gokdemir et al (2023) used handheld TIR and regional TIR studies to establish baseline environmental conditions to establish a detailed method to assess tunnel drainage and its impact on surface vegetation. Their method is highly quantitative and establishes a vulnerability index based on rooting depths and the tunnel dewatering impacts on plant root depths of differing subsurface locations.…”

The California High‐Speed Rail is currently planning a rail corridor through the San Gabriel Mountains. The alignment will require tunnels up to approximately 600 m deep and crossing through the San Gabriel Mountains in the SR 14 area. This study utilized repeated optical and infrared unmanned aerial vehicle (UAV) aerial imagery to document the baseline environmental conditions overlying one of the future high‐speed rail tunnels. Images provide vegetation and soil moisture patterns along the surface route of the corridor for future comparison when the tunneling segments are bored. Analysis of reflectance data revealed subsurface water flow in the Bear Creek‐Sand Canyon Creek Study Area. Using UAVs is considered an effective new tool to detect large‐scale and discrete environmental conditions, perhaps undocumented or unobservable, via standard mapping tools. Setting detailed baseline conditions is important to identify changes that may occur because of future tunneling.

“…Soil, plant, and atmosphere are regarded as dynamic physical systems in which energy transfer and material (water) transport occur all the time [31]. At present, this model has been widely used in agricultural research [32][33][34], but few studies have applied it to the effect of tunnel excavation on plants. The previous studies mostly ana-lyzed the effect of a tunnel excavation on local plants from the perspective of soil water matrix potential (SWMP) [35,36], but ignored other fluxes in the SPAC model, and did not further apply them to the study of ecological water level.…”

Keywordsgroundwater decline ecological water level SPAC model plant wiltDuring the excavation of tunnels in mountainous areas, groundwater may be lost, which affects the surface plants and ecology. In this article, taking Hengwu Tunnel in China as an example, based on the soil-plant-atmosphere continuum (SPAC) model, the relevant parameters were obtained by field test first, and then from the perspective of soil water matrix potential (SWMP) and soil water migration (SWM), the effect of groundwater level decline induced by mountain tunnel excavation on plant growth was studied, and the calculation method of ecological water level was put forward. The results show the following: (1) The wilting of plant roots is a dynamic process of gradual expansion from the middle of the root to both ends, and the response of SWMP in the root region to changes in atmosphere and groundwater level is lagging and non-uniform; (2) SWMP can be used to predict the degree of wilting of plant roots, while the final distribution and value of SWMP are only related to the position of the groundwater level, but not related to the decline rate of the groundwater level; (3) groundwater level and rainfall (P) will affect the value and proportion of each flux in the SPAC model, in which the relative transpiration ratio can be used to evaluate the growth of the plant and calculate the ecological water level of the plant.
