Ionic rare earth (RE) mines use the in situ leaching (ISL) method to operate, but after investigation, it is found that the geological damage caused by RE mines is still serious in recent years. The structure is damaged, which affects the stability of the mine slope and even causes geological disasters such as landslides and collapses to a certain extent, which has a huge impact on the lives of local people. Therefore, it is very important to analyze the slope stability of RE mines. In this study, indoor similarity simulation experiments were conducted using the sensor network (SN) of non-linear data analysis, and its stability of the ISL of ionic RE ore bodies was studied. In addition, an indoor column leaching simulation experiment was carried out to observe the internal fine and microstructure of the ore sample during the whole leaching process using nuclear magnetic resonance (NMR) under the conditions of magnesium sulfate solution and water leaching, respectively. The evolution mechanism of the pore structure was analyzed during the leaching process. The experiments showed that during the whole leaching process, the ore body reaches saturation in the early stages, resulting in a sharp increase in the porosity of the ore sample within the first 1 h due to seepage. Subsequently, the porosity of each sample increases, indicating that the seepage of the leaching solution inside the sample has reached a relatively stable state.

“…A landscape scale understanding of controls on streamflow regimes requires an integrative approach that captures the ecologically and hydrological meaningful characteristics of seasonal flow dynamics (Arthington et al, 2006;Tetzlaff et al, 2005;Tonkin et al, 2021). Environmental tracers, such as stable water isotopes, can be useful for characterizing complex hydrological systems in order to understand hydrological functioning across multiple scales (Ehleringer et al, 2016;Jasechko, 2019;Kendall & McDonnell, 1998;Stevenson et al, 2022). Tracer applications and tracer-based models can provide insight into controls on streamflow generation across different climatic and geographic scales (Bonneau et al, 2018;Stevenson et al, 2022;Von Freyberg et al, 2018).…”

Abstract. Flow regimes are increasingly impacted by more extreme natural hazards of droughts and floods as a result of climate change, compounded by anthropogenic influences in both urban and intensively managed rural catchments. However, the characteristics of sustainable flow regimes that are needed to maintain or restore hydrologic, biogeochemical and ecological function under rapid global change remain unclear and contested. We conducted an inter-comparison of two streams in the Berlin-Brandenburg region of NE Germany, which are both mesoscale sub-catchments of the River Spree; an intermittent rural agricultural stream (the Demnitzer Millcreek) and a heavily anthropogenically impacted urban stream (the Panke). Through tracer-based analyses using stable water isotopes, we identified the dominant physical processes (runoff sources, flowpaths and age characteristics) sustaining streamflow over multiple years (2018–2023), including three major drought years (2018–20, 2021–22). In the urban stream, low flows are regulated through artificially increased baseflow from treated waste water effluent (by up to 80 %), whilst storm drainage drives rapid, transient high flow and runoff responses (up to 80 %) to intense convective summer rainfall. The intermittent groundwater-dominated rural stream experienced extended no-flow periods during drought years (⁓ 60 % of the year), and only moderate storm runoff coefficients (<10 %) in winter along near-surface flows paths after heavy rainfall. In both streams, groundwater dominance with young water influence prevails, with low water ages in the urban stream (<10 %) despite significant urban runoff, and higher ones in the rural stream (⁓15 %). Urban cover resulted in mean transit time of ⁓4 years compared to arable land with ⁓3 years, highlighting the interlinkages of landuse and catchment properties on catchment transit times. Understanding seasonal and interannual variability in streamflow generation through a tracer-based hydrological template, has potential for assessing the impacts of natural hazards on the sustainability of future baseflow management, including wider water quality and ecological implications across anthropogenically impacted environments.

“…Consequently, more hydrological studies are moving towards integrating a more process-based understanding of the spatio-temporal dynamics of the urban water cycle components across the urban critical zone (Arden et al, 2014 ; Cristiano et al, 2020 ; Gillefalk et al, 2022 ; Salvadore et al, 2015 ). Studies investigating urban catchment hydrology have shown significantly lower water ages (Mean Transit Times – MTTs) and higher fractions of young water than non-urban catchment as a result of artificial storm drainage and reduced recharge and groundwater storage under impervious surfaces (Bonneau et al, 2018 ; Kuhlemann et al, 2022 ; Parajulee et al, 2019 ; Soulsby et al, 2015 ; Stevenson et al, 2022 ). Those impacts are likely to be time-variant as urban areas evolve (Birkel et al, 2012 ; Rodriguez et al, 2020 ).…”

We have a poor understanding of how urban drainage and other engineered components interact with more natural hydrological processes in green and blue spaces to generate stream flow. This limits the scientific evidence base for predicting and mitigating the effects of future development of the built environment and climate change on urban water resources and their ecosystem services. Here, we synthesize > 20 years of environmental monitoring data to better understand the hydrological function of the 109-km2 Wuhle catchment, an important tributary of the river Spree in Berlin, Germany. More than half (56%) of the catchment is urbanized, leading to substantial flow path alterations. Young water from storm runoff and rapid subsurface flow provided around 20% of stream flow. However, most of it was generated by older groundwater (several years old), mainly recharged through the rural headwaters and non-urban green spaces. Recent drought years since 2018 showed that this base flow component has reduced in response to decreased recharge, causing deterioration in water quality and sections of the stream network to dry out. Attempts to integrate the understanding of engineered and natural processes in a traditional rainfall-runoff model were only partly successful due to uncertainties over the catchment area, effects of sustainable urban drainage, adjacent groundwater pumping, and limited conceptualization of groundwater storage dynamics. The study highlights the need for more extensive and coordinated monitoring and data collection in complex urban catchments and the use of these data in more advanced models of urban hydrology to enhance management.
