Morphological analysis and evaluation of Givi-chay River conduit form (northwest of Iran)
In this study, the factors affecting the formation of channel patterns and dynamics in the Givi-chay River during the period 2019–2000 were analysed. To evaluate the river strength, flaw stress and its effects on channel morphology, Landsat 7 and 8 images, topographic maps, geology, and hydrological...

| description | In this study, the factors affecting the formation of channel patterns and dynamics in the Givi-chay River during the period 2019–2000 were analysed. To evaluate the river strength, flaw stress and its effects on channel morphology, Landsat 7 and 8 images, topographic maps, geology, and hydrological and field data were used. According to the results of the calculation of hydrological indicators, in terms of 15, the index, a significant difference is seen among upstream and downstream stations. Therefore, it can be found that the presence of the Givi Dam has created a good platform for intensifying the hydrological and morphological changes of the river plan. The particular strength of the river in all parts of the fourth interval and the ninth, 12th, eighth (second interval) levels causes the erosion threshold to soar. The highest amount of shear stress was observed in the second interval at 12, 13, and 9, respectively. Generally, the changes of the Givi River Plan include expansion of existing meanders, displacement of paths, increase of curvature and formation of small meanders and formation of channel pattern and dynamics, affected by discharge provision, sediment discharge due to dam construction, lithological resistance of the riverbed and human interference.
