The Role of Geological and Geomorphologic Characteristics on the Sirvan River Pollution
Geological and geomorphologic factors can have effect on a river contamination. The West part of the Sirvan catchments has been selected to study the role of these factors.

| description | Geological and geomorphologic factors can have effect on a river contamination. The West part of the Sirvan catchments has been selected to study the role of these factors. In this part, six sections of measurements are selected where 9 contamination indices were obtained from samples taken 2 or 3 times at each season. Comparing the experiment results with that of pollution indices and upstream geological and geomorphologic characteristics show that despite Sirvan pollution by sewages, other factors likerock type, a given stage of evolution in some parts of catchments, and different land use create a situation that make to carry sediments based on kind and amount of precipitation. So, it produces different turbidity and TDS on different parts of catchments that these indices affect, in turn, other indices as E.C., salinity and oxygen dissolve. Impermissible gravel is washed from river beds and erosion of terraces in some parts of river is locally agents to produce sediment. However, rock kinds and it's weathering, instability in some slopes and gelifluction debris that filled subvallys of Sirvan River are important factors to play role in amount and kind of delivered sediments. |
