Abstract. The discharge measured in karst springs is known to exhibit distinctive long tails during recession times following distinct short-duration discharge peaks. The long-tailed behavior is generally attributed to the occurrence of tortuous, ramified flow paths that develop in the underground structure of karst systems. Modeling the discharge behavior poses unique difficulties because of the poorly delineated flow path geometry and generally scarce information on the hydraulic properties of catchment-scale systems. In a different context, modeling of long-tailed behavior has been addressed in studies of chemical transport. Here, an adaptation of a continuous time random walk–particle tracking (CTRW-PT) framework for anomalous transport is proposed, which offers a robust means to quantify long-tailed breakthrough curves that often arise during the transport of chemical species under various flow scenarios. A theoretical analogy is first established between partially water-saturated karst flow, characterized by temporally varying water storage, and chemical transport involving the accumulation and release of a chemical tracer. This analogy is then used to develop and implement a CTRW-PT model. Application of this numerical model to the examination of 3 years of summer rainfall and discharge data from a karst aquifer system – the Disnergschroef high-alpine site in the Austrian Alps – is shown to yield robust fits between modeled and measured discharge values. In particular,...

See AlsoDollar Tree Bandera PointeKarst is a term used to describe an area where limestone bedrock has eroded in an irregular manner. This irregular erosion is caused by the dissolution of limestone, which occurs as water is transported through the rock. As a result, these areas are often characterized by extremely variable rock surfaces, rock pinnacles, solution channels, sinkholes, and caves that may not be able to adequately support the proposed site improvements and buildings.

11. Modelling hazards impacting the flow regime in the Hranice Karst due to ...
... 2024-21', Ulf Mohrlok, 25 Apr 2024. The authors present a very simple modeling approach to investigate the hydraulic behavior of a poorly known karst system.
Abstract. This study examines hydrogeological risks associated with the construction of the proposed Skalička Dam in the vicinity of the Hranice Karst. Prompted by the catastrophic floods in 1997, the design of the dam aims to mitigate floods along the Bečva River downstream of the reservoir. However, concerns have been raised regarding the potential disturbance of the natural groundwater regime in the Hranice Karst and the source of mineral waters for the Teplice spa. This is particularly due to the dam's location in an area with limestone outcrops potentially susceptible to surface water infiltration. Previous studies have also highlighted the strong correlation between the water level in the Bečva River and the water level in karst formations such as the Hranice Abyss, Zbrašov Aragonite Caves, and other caves in the locality. To address these concerns, a nonlinear reservoir-pipe groundwater flow model was employed to simulate the behaviour of the Hranice Karst aquifer, and specifically the effects of the dam reservoir's impoundment. The study concluded that the lateral variant of the dam would have a practically negligible impact on the karst water system, with the rise in water level being only a few centimetres. The through-flow variant was found to have a more significant potential impact on water levels and the outflow of mineral water in the spa, with a piezometric rise of about 1 m and an increase in the karst water discharge to the Bečva River of more than 50 %.
