Flood Hazards of Talar River

   Head branch of Kazemroud River is located in 2500 meters heights south of Ghaemshahr. Morphology of Talar River shows a combination of meander and River-Valley featurers. There are several meander in Talar river flow path. Talar River flows parallel with Firouzkooh-Ghaemshahr road and it arrives to Caspian beach area in Malek Kala village. Length of Talar river in Caspian beach is more than 25 Km. the local base level (LBL) of Talar river is -24 m and its bed gradient is 10/1000 (1 percent).
   Tralar River morphology shows an active flood plain that be confined by 2 river terraces (H1 and H2). These terraces have different topographic contours.
   Maximum width of Talar river flood plane is more than 100 meters but its active flood plain width is up to 40 meters. H1 Terraces defines 20 years recurrence period area. H2 terraces have 5-7 meters hight and are the topmost morphic features in Talar River.this terraces can define 100 years recurrence period flood area. Because of H2 terraces are away from Talar river flood flows, constructions and farms are developed in the top of them.
   There aren't any plants in Talar Active flood plain and this trait is the most important way to recognition of flood area.
   Vulnerable area of Talar River lies between 1/5 Km south of Ghaemshahr (Talar village) and 300 m north of Talar park.
   Talar River approximately overflows each year. Maximum volume of Talar is end of winter and first of spring. The most severe floodwater of Talar has happened in 1379.
   Terraces walls in the most areas makes from Cohesive brown silts (loess) and take place of landslide in these walls are probably.
   Talar River Width is considerable. This width can decrease the velocity and destruction power of floodwaters. Therefore floodwater controlling structures are not necessary. In zones that walls are retreating with more velocity, establishing of protective blocks is necessary.
