| Abstract:
Exploitation of river sand and gravel is a source of mane natural organizational
financial and environmental problems. Recent years have seen mane efforts to improve the
river material exploitation system ,as Minab river is one of the richest sources of sand and
gravel in Iran numerous factories have been established on is bed to exploit its material.
Minab dam has caused total hinderance of base debit downstream flow and consequently
downstream transmission of sediments especially coarse grains and erosion of this
alluvial system bed and sides it has also led to river course change riverbed and side
erosion meander expansion increasing riverbed widening endangering river constructions
e.g. Minab bridge Minab dam and dikes and threatening population centers farma and
gardens adjacent to the river arelated problem is alluvial material exploitation in recent
years so meny measures have been taken to improve this exploitation system it should be
remembered however that within the current system technical issues water and sediment
direction and its contribution to the river geomorphology as well as considering natural
effects and condeguences of the river material exploitation are among the long-range
objectives in relation to those alluvial system.
