The fluid flow system can be described by an equivalent electromagnetic system. In this paper a successful application of the Biot–Savart law in hydraulics is presented. Similarity between the magnetic field of a current wire and the isovel contours...

normalized form, which can be used for estimation of discharge in artificial and natural

channels. It is assumed that the velocity at each arbitrary point in the flow section is affected ...

Abstract: Maghrebi has previously introduced a model for the production of isovel contours in a normalized form, which can be used for estimation of discharge in artificial and natural channels. The model is applied to a tidal river with partially...

. This research aims to facilitate determination of

discharge by applying remote sensing technique as well as the concept of isovel contours. For

this purpose, the geometry of the river cross section is determined using remotely sensed data...

rivers using the concept of isovel contours with the

corresponding hydro-geometric parameters of the cross sections which was first introduced by

Maghrebi (2006). The most important advantage of the proposed method in estimation of the...

of this method, discharge can be estimated automatically with a

fixed measurement location in the river section or on the water surface, which is associated with minimum energy and cost consumptions. For

the proposed model, we determine the isovel...

new approach that is based on the concept of the cross-sectional isovel contours is introduced for
estimation of the stage-discharge curves in compound channels. The multivariate Newton’s method
is applied to the difference between the observed...

The use of reliable stage-discharge curves is one of the most important issues in the management of
water resources and river engineering. Discharge measurement in natural rivers is generally difficult
and accompanied ...
