Seasonal Variation of the Solute and Determine the Solubility of Limestone Formations

Study of karstic rocks properties, understanding teh chemical and physical properties TEMPhas a special place in resent researches. By understanding of teh properties mentioned such as Bulk density, Porosity, coefficient of solubility, solubility rate … can be evaluated for karst development in teh soluble rocks. Teh purpose of dis study is teh assessment of seasonal variations of teh solute and solubility of karstic formations in Khorram Abad, Alashtar and Biran Shahr. To do so, circulation technique, as a commonly used method was applied to determine teh amount of solubility. Also, teh solute load was determined. Teh result showed dat teh maximum and minimum solubility (k) of Asmari-Shabazan and Omas formations can be 1.27*10-6 and 1.02*10-6 m s-1 respectively. Also result shown dat Khorramabad and Biranshahr watersheds TEMPhas a maximum and minimum solute load, respectively. In dis regard, annual solute load were estimated to be around 75.61 *103, 47.56 *103 and 44.49 *103 tons/year in Khorram Abad, Alashtar and Biran Shahr watersheds respectively.
