the abharroud basin is an important region in the archeological studies of northwestern outskirts of the central plateau, and west and northwest of iran. considering its environmental capabilities and geographical location, studying the region can leads us to a better understanding of regional relations and also inter-regional interaction between the mentioned cultural-geographical regions. how...

knowledge about low flow statistics is essential for effective water resource planning and management in ungauged orpoorly gauged catchment areas, especially in arid and semi-arid regions such as iran. we employed a data set of 20 riverflow time-series from the iranian central plateau river basin, iran to evaluate the low-flow series using several frequencyanalysis methods and compared the resu...

The genus Melilotus contains altogether some 20 species (WIERSEMA et al. 1990) in the world which mostly distributed in Europe, Central and SW. Asia and N. Africa (HUCHINSON 1964). BOISSIER (1872) listed 13 species of Melilotus in which 6 of them are found in the Iranian flora. PARSA (1948) following Boissier’s work referring some new collections made by other workers, listed the same species n...

using global free air gravity and topography data, first we have calculated a bouguer anomaly (ba) map for iranian plateau and then computed the residual isostasy anomaly map under the airy-heiskannen assumption. the term residual is used as to reflect the assumption of local isostatic compensation in contrast to a regional isostatic compensation. the value with which the gravity effect of the ...

Abstract A record-breaking heat wave hit the Yangtze River valley during boreal summer of 2022, and caused severe social economic losses. One prominent feature this long-lived event was its persistence abnormal intensification in August. This study investigated physical mechanisms be responsible for late under background a La Niña event. The prolonged directly related to westward extension west...

Prehistoric archaeological sites in the center of the Iranian Plateau suddenly disappeared around the end of the 4th millennium BCE. At Tepe Sialk, near Kashan, the last cultural period, namely Sialk IV - probably established around 3400 BCE after the last settlements of Sialk III6-7b - was abandoned approximately after 500 years. The material culture of this period, known as Proto-Elamite peri...
