Analysis of discharge rates in rectangular slit, ogee, and sharp-crested weirs

Frontiers in Built Environment
Climate change has made flash floods increasingly common. It's crucial to have confidence in the structural integrity of dams during a flash flood. According to the International Commission on Large Dams (ICOLD), approximately one-third of dam failures ...

Modeling discharge capacity of labyrinth weirs through a learning machine approach [PDF]

Journal of Applied Research in Water and Wastewater, 2019
In this paper, the discharge coefficient of weirs is simulated by the extreme learning machine (ELM). To this end, seven different ELM models are introduced by the input parameters.

Molten Salt Synthesis of Disordered Spinel LiNi0.5Mn1.5O4 with Improved Electrochemical Performance for Li-ion Batteries

International Journal of Electrochemical Science, 2018
Disordered spinel LiNi0.5Mn1.5O4 (LNMO) was successfully synthesised via a molten-salt method using a mixture of LiOH⋅H2O and LiNO3 salts. The precursor was annealed at 750, 850 or 950 °C for 12 h, and the effects of calcination temperature on the ...

II. On stratified discharges. V. Discharge from a condenser of large capacity [PDF]

Proceedings of the Royal Society of London, 1878
Abstract The principal object of the following communication is to describe an instrumental arrangement which has proved very convenient for the production of steady striæ. The first attempt which was made nearly two years ago (February, 1876), consisted in charging a Leyden battery of nine large jars by means of an induction coil ...

Discharge Capacity of Prefabricated Vertical Drain Confined in-clay

Geosynthetics Engineering Journal, 2000
This paper reports the long-term discharge capacities of four types of prefabricated vertical drains (PVDs) confined in clay. The results indicate that under clay confinement, the PVD discharge capacities significantly reduced with time. The discharge capacity reduction may be caused by creep deformation of the PVD filter or clogging of the drainage ...

Anfis to estimate discharge capacity of rectangular side weir

Proceedings of the Institution of Civil Engineers - Water Management, 2013
The adaptive neuro-fuzzy inference system (Anfis) is considered for flow over rectangular side weirs located on a straight channel as a substantial part of distribution channels in irrigation systems and treatment units. To estimate the outflow over a rectangular sharp-crested side weir, the discharge coefficient in the side weir equation needs to be ...
