Karst systems, such as caves, provide a unique opportunity to study the groundwater from inside in contrast spring studies, where hydrographs, chemographs, and thermographs show an integrated signal entire catchment aquifer. Studies karst springs that recharge conduit characteristics significantly influence how temperature is transmitted thus could inform on structure of underground flow paths....

A study was performed to determine groundwater fluoride concentration of Posht-e-Kooh-eDashtestan area located in southern Iran. Groundwater samples were collected from 26 wells, 4 springs, during dry and wet seasons. Fluoride concentration was determined in the water samples using SPADNS method. The results showed that fluoride concentrations are above the World Health Organization (WHO) maxim...

The discharge from most karst springs exhibits a consistent and reasonably predictable response to recharge but few exhibit short-term (‘rhythmic’) changes in flow that are commonly attributed the geometry of feeder conduits action siphons. This paper investigates water system rhythmic episodic due variations two phreatic (Main Rising (MR) Whirlpool (WR)) pass through Speedwell Cavern en route ...

vulnerability and contamination risk assessment is of great importance in karst aquifer management. because of vastness of karst in zagros, natural conditions and human activity within the region of aquifer, pollution emission has become one of the most important challenges in front of zagros aquifers. the purpose of this study is to assess marab aquifer vulnerability, using riske model and, de...

Water is one of our most important resources. Both surface water and groundwater are used by humans for drinking, irrigation, transportation, entertainment, and are a major service for ecosystems. Almost all surface water features, such as streams, rivers, and lakes, interact with groundwater by exchanging water between these two reservoirs. Surface water can become polluted depending on land u...
