Zoning of Hydrogeological Drought Severity in Arid Regions and It’s Relaion with Meteorological Drought(case study: Garmsar Plain)

Zahra Noori; Arash Malekian

Volume 76, Issue 2 , August 2023, , Pages 103-114


  Groundwater is important water resource supply, especially in arid and semi- arid regions. Increased utilization of the ground water aquifer leads to significant reduction in the storage of reservoirs. This study evaluates the hydrogeological drought in Garmsar plain using Groundwater Resource Index ...  Read More

Hossein Eslami; Ali Salajagheh; Shahram Khalighi sigaroudi; hasan Ahmadi; Shamsollah Ayoubi

Volume 67, Issue 3 , December 2014, , Pages 393-406


  Rainfall erosivity is the ability of rainfall to detach the soil particles. This study was conducted to evaluate spatial variability of rainfall erosivity indices in Khouzestan Province. The point data of indices (EI30, AIm, KE>1 and Onchev indices) in 74 stations were used to generate spatial erosivity ...  Read More

Spatial variation of nitrate concentrations in groundwater by Geostatistics (Case Study: Kurdan Plain)

Kh. Osati; A. Salajegheh; S. Arekhi

Volume 65, Issue 4 , March 2013, , Pages 461-472


  Spatiality assessment of groundwater pollution is very important to determine water quality condition, pollution sources and management decisions. In this case, GIS and geostatistics methods can be useful tools. Spatiality of groundwater quality parameters, in relation with various land uses, can be ...  Read More
