Nitrate Hysteresis as a Tool for Revealing Storm-Event Dynamics and Improving Water Quality Model Performance

Admin Husic et al.

Summary: Understanding the physics of nitrate contamination in surface and subsurface water is crucial for improving downstream water quality. This study utilized high-frequency data to develop a conceptual model for nitrate hysteresis in an agricultural karst spring in Kentucky, USA. By integrating hysteresis analysis into numerical model evaluation, the simulated nitrate prediction bounds and parameter uncertainty were significantly reduced. This study highlights the importance of integrating high-frequency sensor data into numerical models to improve process representation and reduce modeled uncertainty.

Quantifying and interpreting the hysteresis patterns of monthly sediment concentration and water discharge in karst watersheds

Miaomiao Zhu et al.

Summary: Hysteresis loop models are effective tools for understanding sediment dynamics and managing sediment-discharge resources. An improved differential hysteresis index was developed to quantify sediment-discharge relationships in karst watersheds in southwest China. The results showed that clockwise hysteresis was dominant, accounting for 74% of the total hysteresis. Climatic factors and vegetation extent explained 50% to 75% of the hysteresis between sediment concentration and water discharge. The study extends the applicability of differential hysteresis indices and provides valuable information for soil erosion control in karst watersheds.

Temporal and spatial characterization of sediment transport through a karst aquifer by means of time series analysis

Damir Jukic et al.

Summary: This study investigates the sediment transport process in a karst aquifer using time series analysis. The results show that the partial cross-correlation function is useful for studying mass transport and determining the specific contribution of rainfall locations to spring water quantity and quality. The study provides valuable insights into sediment origins and the timing of rainwater arrival in the karst aquifer.

Impact of Withdrawals on Karst Watershed Water Supply

David Labat et al.

Summary: Karst systems are composed of heterogenous aquifers with non-linear hydrogeological behavior, which leads to difficulties in management and potential conflicts over resource use. A study on the second largest karst system in France, the Touvre karst system, shows that withdrawals significantly impact spring discharge, with a decrease of 10% to 20% in low-flow annual discharge. Future research will address issues related to climate change projections.

Sediment transport investigation in a karst aquifer hypothesizes controls on internal versus external sediment origin and saturation impact on hysteresis

Leonie Bettel et al.

Summary: Karst springs are important drinking water sources, but the routing of contaminants like sediment in karst remains uncertain. Through data collection and modeling, we identified external sediment loading as the primary control of sediment load at springs, contrary to previous assumptions of internal resuspension.

Strategies for identifying pollution sources in a headwater catchment based on multi-scale water quality monitoring

Franciele de Bastos et al.

Summary: This study aimed to describe the spatial and temporal dynamics of water quality in rural headwater catchments and its implications for environmental monitoring programs. By monitoring parameters in different sub-basins with physiographic traits, it was found that agriculture had the greatest impact on water resources.

Hydraulics and Turbidity Generation in the Milandre Cave (Switzerland)

Cecile Vuilleumier et al.

Summary: This study discusses the sources and transport pathways of turbidity in karst springs, revealing the mechanisms of turbidity changes during flood events through observations and numerical simulations. Turbidity mainly comes from underground sediment and soil, and is related to the average boundary shear stress within the conduit network.

Karst Recharge Areas Identified by Combined Application of Isotopes and Hydrogeological Budget

Silvia Iacurto et al.

Summary: The identification of recharge areas in karst aquifers with the use of stable isotopes and hydrogeological tools has provided valuable insights into the sustainable management of groundwater resources. The study successfully combines an isotope-driven model with a quantitative hydrogeological tool to determine recharge areas in karst mountain basins, showing that as average recharge elevations increase, recharge areas decrease.
