Abstarct: The Palangan area is a part of of Shahu mountains situated 55 kilometers northwest of Kamyaran city (Kurdestan). These mountains lie in a distinct band of rocks Jurassic- Cretaceous and Oligomiosen that is known as High Zagros zone. In order to study the hydrogeological and hydrogeochemical characteristics of Palangan karst springs, physical and chemical characteristic of springs including electrical conductivity, acidity, discharge, temperature, dissolved carbon dioxide and major anions and cations were measured during a water year. In addition, physical and chemical properties of the Tangivar river were measured simultaneously with the springs. Evaluating the chemistry of springs show that the variation of most studied parameters is high which indicate the main flow system in karst region is conduit. The variation coefficient of has been very high 82%, The falling limb of hydrograph includes two slopes, i.e. and which are and , respectively. As it can be seen the value of is very large which indicates a rapid discharge due to existence of large conduits in the karstic aquifers. The variation coefficient of water temperature and electrical conductivity in the studied springs is like variation coefficient of discharge which all of them illustrate a conduit system. The catchment area of Palangan karst springs is about 219 square kilometres which is characterised by the existence of karst valleys, sinkholes and karst plains.
