Effective Measures of ''Effective Discharge''

World Environmental and Water Resources Congress 2008, 2008
Abstract The concept of effective discharge, Qe, was introduced by Wolman and Miller (1960) as that stream discharge that transports the most sediment over time. Recently, the validity of Qe as an overall descriptor of sediment transport has been questioned because of its various interpretations and methods of calculation.

Measuring Flood Discharge

2017
With a continuous global increase in flood frequency and intensity, there is an immediate need for new science-based solutions for flood mitigation, resilience, and adaptation that can be quickly deployed in any flood-prone area. An integral part of these solutions is the availability of river discharge measurements delivered in real time with high ...

Partial Discharge Measurement

2014
This chapter is devoted to the measurement of partial discharges (PD) localized in weak spots of dielectrics if subjected to high test voltages. As standards for PD measurement s have been introduced only for quality assurance tests of HV apparatus energized by power frequency AC voltages (50/60 Hz), the following treatment refers mainly to this test ...

River discharge and bathymetry estimation from SWOT altimetry measurements

, 2020
An inverse method to estimate the discharge of rivers observed by satellite altimetry is developed and assessed. The flow model relies on the Saint-Venant equations combined with a dedicated algebraic system.

Power Measurements of Spark Discharge Experiments

Origins of life and evolution of the biosphere, 1998
An accurate and precise knowledge of the amount of energy introduced into prebiotic discharge experiments is important to understand the relative roles of different energy sources in the synthesis of organic compounds in the primitive Earth's atmosphere and other planetary atmospheres.

Measuring Irrigation Well Discharges

Journal of Irrigation and Drainage Engineering, 1999
Irrigation wells frequently discharge directly into canals. Upstream elbows, the pump head, or other pipe fittings may produce a distorted flow profile that is detrimental to the proper installation and operation of commonly available pipe meters. Before attempts to condition the flow with longer discharge piping or straightening vanes, it is desirable

Probe measurements in anisotropic discharges

Journal of Applied Physics, 2003
A current–voltage characteristic of one-side planar and cylindrical probes was considered for the use in the determination of plasma parameters when the electron velocity distribution functions (EVDFs) were significantly anisotropic. The EVDFs, space potential, and rates of inelastic process in pulse modulated and stratified discharges were obtained ...

Discharge measurement structures

2017
This chapter introduces calculation procedures for discharge measurement structures. It focuses on a rational expression for discharge in terms of typical flow quantities and the geometry of the structure. The chapter presents the general one-dimensional flow equations, and a demonstration that critical flow can occur if either the cross-sectional area

Measurement of River Discharge

Journal AWWA, 1925
of usefulness grew until today they assist in the solution of problems that affect every citizen. The number of measuring stations in operation has grown from a few in the early 90's to nearly 1700 this year. During the fiscal year of 1924 there were made approximately 12,000 regular and miscellaneous discharge measurements. These statements refer only
