Flood Hazards of Chalakroud
Flood Hazards of Chalakroud river
 
  Page 1
 
   Head branch of Chalakroud River has located in 1500 m Chinehkooh heights south of Ramsar and called Jalisan River. Jalisan River after joint with Laktarashan River makes Chalakroud River. Local base level (LBL) of Chalakroud River is 25 meter and it's bed gradient is 3.5/1000 in Caspian Coastal Zone. This river cuts Ramsar-Tonekabon road in Km: 10+100.
    uncemented coarse grain alluviums makes Alluvial terraces of this river and thus they are completely in debris form. Chalakroud account as a width river. Morphology of Chalakrour is a river-valley that minimum width of its stream bed is 30-40 m. flood plain width of river is up to 300 m.
   River bed has made by gravel-rubble materials and confined by river terraces from both side. In Chalakroud terrace walls have made by different hight. Terraces walls have 1-1.5 m and 2-3 m hight, and highest wall has 5 m hight.
   because of material type of Terraces in both side of Chalakroud, they are gently retreating and thus the width of river are widening. Width flood plain in chalakroud river decreases depth and rate of stream flow.
   Chalakroud river approximately experiences floodwater each year, but floodwaters in 1334, 1369, 1372 and 1380 years were the important floods of this river.Vulnerable area of Chalakroud river has 2.5 Km length. South limit of Chalakroud Vulnerable area is Norodin Mahaleh damaged iron bridge (in 2.4 Km south of Chalakroud) and north limith of it is 100 m north of Jadeh Kenar (around of beach manse). The flood intensity is n't equal in this 2.5 Km area.
   There was not construction in active flood plain of Chalakroud River but there are agricultural areas in active flood plain.
