INTRODUCTION
The Kavar dam is a rock-fill dam for storage water. The dam is located in the southwest of Iran in the Fars province. It provides a barrier for water from Ghareh Aghage River. The catchment's area is approximately 1601 [km.sup.-2] and the total volume of the reservoir is 242*[10.sup.6] [m.sup.-3]. The rock mass in the foundation of the dam consist of Oligocene, Eocene and Miocene limestone and marls. The main problem of this dam is water escape from it's axe and abutments. In order to solve this problem grouting is commended. In this regard, the permeability of rocks was determined and analyzed trough about 82 Water Pressure Tests (WPT) in 6 ...
