River System Style Frameworks, New Approach to Management of rivers (Case Study: Karaj Arangeh basin)
Published 2021-03-01“…Arangeh River basin were identified in 1and 3 styles, including: Headwater, Gorge style in confined valley setting, planform controlled, floodplain bed, low sinuosity cobble, low sinuosity gravel, bedrock controlled sand, meandering gravel, unconfined low sinuosity cobble with Side stabilized, partly-confined low sinuosity cobble with Side stabilized, partly confined Asymmetric valley with cobble, , partly confined symmetric valley with cobble ,Artificial bed.Geomorphic conditions of each of the styles were evaluated in the two stage of river style framework. at this stage of adjustment of Each style is determined to the confusion of peak flow by using criteria such as channel characteristics (size, shape, morphology Bank and plants channels), channel plan form (sinuosity, lateral stability, geomorphic units into the channel and River flood plain and plants) and features bed . Two Style had good geomorphic conditions (floodplain bed bedrock controlled sand, unconfined low sinuosity cobble with Side stabilized) show the potential of a good adjustment, and the reach has a good of potential adjustments are more sensitive to changes . …”

Short-Term Optimal Scheduling Method of Cascade Hydropower Stations Based on Segmented Load Construction Strategy
Published 2023-01-01“…With the rapid development of China's economy,electricity demand has increased.As the largest clean energy in China,hydropower has been put into large-scale and centralized production,and the most complex large-scale hydropower system in the world is formed.However,short-term hydropower optimal scheduling faces the serious challenge of the curse of dimensionality due to massive cascade hydropower stations,numerous hydropower constraints,and time-sensitive scheduling requirements.Therefore,this paper proposes a short-term optimal scheduling method for cascade hydropower stations based on a segmented load construction strategy.First,the selection rules of the hydropower stations to be regulated are formulated from the perspective of the regulation performance,location,and task of the cascade hydropower stations.Then,a method is given to divide the complex original load into two sub-load processes,namely the segmented load process with time reduction scale and the residual load process with frequent fluctuations.Finally,the adjustment method is given,and the particle swarm algorithm is used for traversal and optimization at different stages,so as to find the load division process when the target is optimal.By taking seven cascade hydropower stations in a certain river basin in southwest China as research objects,a mature particle swarm algorithm is used to simulate the typical day during the flood and dry periods.The results show that the segmented load construction strategy proposed in this paper can effectively reduce the solution complexity,and the appropriate number of segments can improve the solution efficiency while ensuring the solution quality.In addition,this method greatly reduces the output fluctuation of auxiliary hydropower stations and helps to reduce the difficulty of scheduling and unit loss.Therefore,the method proposed in this paper can provide a reference for solving the short-term scheduling of large-scale cascade hydropower stations and is of good practical value.…”
