Environmental flow is explained as the period of time, quantity and the amount of required water for maintaining the water, fresh, the river’s ecosystem, human beings’ welfare and the life depending on the water. The main goal of this paper is to investigate and compare the hydrological methods including Tennant, aquatic flow, Tessman, analysis of the flow duration curve and the flow duration c...
monitoring of road traffic noise is becoming an important issue in modern cities due to the spreading of noise pollution and the extension of monitored areas. thus, the stratified spatial sampling is frequently applied to reduce the costs and provide adequate accuracy in order to obtain reliable noise maps. the definition of the strata in the sampling may refer to the legislative classification...
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
Online and accurate traffic classification is a key challenge for network management. Internet traffic classification based on flow statistics using machine learning method has attracted great attention. To solve the drawback of the previous classification scheme to meet the requirements of the network activities, our work mainly focuses on how to build an online Internet traffic classification...
Mathematically, the problem of flow field classification can be analyzed by eigenanalysis deformation-rate tensor; however, such analysis technique have not been commonly applied in fluid processing. We derive a simplified objective scheme based on invariants strain-rate tensor and vorticity tensor. Multiaxiality flow, which is related to type elongation, converging/bifurcating characterized te...
