Deducing the weir flow stage-discharge relationship is a classical hydraulic problem. In this
regard Buckingham's theorem of dimensional analysis can be used to find simple and …

In the present research, three different data-driven models (DDMs) are developed to predict
the discharge coefficient of streamlined weirs (C dstw). Some machine-learning methods …

The discharge characteristics of flow over and under different weir-gate structures were
investigated using dimensional analysis and multivariable regression techniques. Based on …

Weirs are simple devices widely applied for flow measurements in open channels. These
hydraulic structures are characterized by a stage-discharge relationship which mainly …

The stage-discharge relationship of a weir is essential for posteriori calculations of flow
discharges. Conventionally, it is determined by regression methods, which is time …

In this paper, the outflow process of a triangular broad-crested device is examined using the
dimensional analysis and the incomplete self-similarity theory. A new theoretical stage …

A comprehensive study was performed to examine the flow characteristics over rectangular
sharp-crested side weirs based on the traditional weir equation. To obtain a generally …

The flow process of weirs of finite crest length is analyzed on the basis of the dimensional
analysis and incomplete self-similarity theory. The crest length is incorporated in the …

In this paper, the outflow process of a sharp-crested and broad weir is studied using the
dimensional analysis and the incomplete self-similarity theory. The new stage discharge is …

The deduction of the weir flow stage-discharge relationship is a hydraulic problem generally
solved by energy considerations and using the discharge coefficient to correct the gap …
