Transfer of dissolved gases through a thick karstic vadose zone – Implications for recharge characterisation and groundwater age dating in karstic aquifers

A dimensionless number describing the effects of recharge and geometry on discharge from simple karstic aquifers

[1] The responses of karstic aquifers to storms are often used to obtain information about aquifer geometry. In general, spring hydrographs are a function of both system geometry and recharge. However, the majority of prior work on storm pulses through karst has not studied the effect of recharge on spring hydrographs. To examine the relative importance of geometry and recharge, we break karsti...

Classification and identification of karstic aquifers in the OSHTORANKUH region

The karst areas refers to individual areas that shaped by the dissolution of bedrock and subsurface drainage grid development and are connected mainly with limestone. The karstic formations outcrop 20 percent of the land surface of the planet is covered that 11 percent of Iran are part of this 20% is included. The ZAGROS region of origin karstic formations in the country that the formation of k...

Using Pedotransfer Functions in Vadose Zone Models for Estimating Groundwater Recharge in Semiarid Regions

Assessing Vulenerabilty of Karstic Aquifers in Kermanshah Plain and Bistoon-Parao Mass Using COP Model

Vulnerability assessment and mapping of hazard pollution is raised on as an important management strategy to protect the karst. Karstic aquifers in semi-arid regions of the West of Iran with regard to the natural conditions of the region, are susceptible to contamination. Estimation of amount and vulnerability mapping of aquifers in the karst religion of Bistoun- Paraw – Kermanshah plain agains...

Artificial recharge through a thick, heterogeneous unsaturated zone.

Thick, heterogeneous unsaturated zones away from large streams in desert areas have not previously been considered suitable for artificial recharge from ponds. To test the potential for recharge in these settings, 1.3 x 10(6) m(3) of water was infiltrated through a 0.36-ha pond along Oro Grande Wash near Victorville, California, between October 2002 and January 2006. The pond overlies a regiona...
