Quantifying the effects of watershed management projects is a first step in the evaluation of their efficiency. Selecting suitable index for evaluation is an important concern in an evaluation process and is determined on the basis of project type, evaluation method, required accuracy, and available data. Watershed management projects have been initiated in Goosh-Bahreh Watershed, Khorasan...
Due to the growing use of Plug-in Electric vehicles in transportation networks, scheduling the charge/discharge of electric vehicles in parking lots can have great impacts on the distribution network's resiliency. This paper presents a Bi-level optimization model to improve the resiliency of the distribution network that takes into account the interaction between the distribution network island...
Prediction of flood peak discharge and runoff volume is one of the major challenges in the management of watersheds. The present study was carried out to estimate event flood peak discharge and runoff volume using artificial neural network (ANN) and adaptive neuro-fuzzy inference system (ANFIS) in Kasilian watershed, Iran. For this purpose, 15 rainfall characteristics were considered for 6...
Spillways are responsible for draining floods in dams. However, morning glory spillways are considered as free spillway type. In floods, a submerged flow is formed in their crest. This factor leads to severe pressure fluctuations in the shaft, suction and vibration of the structure and also reduces the spillway efficiency. Insufficient knowledge of the hydraulics of the submerged flow will be a...
abstract bottom rack intake is one of the most popular structures used for diverting water in mountain region. corrosion and rotten problems of bottom racks inspire the introduction of a new system of bottom intake in which a porous media is replaced by the bottom rack. obviously, clogging and reduction of diverted discharge are the most important problems in this new system, too. in this paper...
We investigate the triggering and guiding ofDChigh-voltage discharges over a distance of 37 cmby filaments produced by ultraviolet (266 nm) laser pulses of 200 ps duration. The latter reduce the breakdown electric field by half and allow up to 80%discharge probability in an electric field of 920 kVm. This high efficiency is not further increased by adding nanosecond pulses in the Joule range at...
