The bioavailable contents of heavy metals in karstic soils are a subject increasing concern since the uptake by plants can pose severe threat to food safety and public health. However, their effective factors poorly understood karst regions. Calcareous soil red developed from carbonate clastic rocks, respectively, were chosen typical region (Guilin) southwestern China, total (CT) available (CA)...

We study the well-posedness of a coupled Cahn-Hilliard-Stokes-Darcy system which is a di↵use-interface model for essentially immiscible two phase incompressible flows with matched density in a karstic geometry. Existence of finite energy weak solution that is global in time is established in both 2D and 3D. Weak-strong uniqueness property of the weak solutions is provided as well.

In this research, recognition of karstic water-bearing zones using the management of exploration data in Kal-Qorno valley, situated in the Tepal area of Shahrood, has been considered. For this purpose, the sequential exploration method was conducted using geological evidences and applying remote sensing and geoelectrical resistivity methods in two major phases including the regional and local s...

The need for clean groundwater resources to have sustainable development in a country is undoubted. Due to the importance and high quality of karstic waters in supplying water in Iran especially in Shahrood city, it is attempted in this research work to recognize and explore karstic waters in southwest of Tepal area, Shahrood. For this purpose, integration of the results obtained from the metho...

In February 2002, during speleological exploration of a karstic system in the southwestern Carpathian Mountains, Stefan Milota, Adrian Bı̂lgar and Laurentiu Sarcina discovered a previously unknown karstic chamber with abundant remains of Ursus spelaeus, occasional other mammalian skeletal elements, and a largely complete human mandible on the paleosurface. The karstic chamber was designated the ...

To explore the effect and applicability of contour reverse slope terraces in water soil conservation karstic red clay area northern Guangxi, rainfall simulation experiments were conducted on bare slopes laid with to find erosion pattern response different intensities (15, 30, 50 mm/h) bedrock porosities (1%, 3%, 5%). The results showed that can change spatial distribution surface runoff, divert...

Speleothems are primarily studied in order to generate archives of climatic change and results have led to significant advances in identifying and dating major shifts in the climate system. However, the climatological meaning of many speleothem records cannot be interpreted unequivocally; this is particularly so for more subtle shifts and shorter time periods, but the use of multiple proxies an...
