In present study, an experimental based study of meander evolution was employed to develop a predic-tion formula for identifying the pool-point bar location by using the dimensional analysis technique and multiple nonlinear regressions. Through the experimental work on a race of the non-uniform river sand, a set of experimental runs have been carried out through combining different hydraulic and geometric parameters to produce different empirical conditions that have a direct impact on the pool-point bar location. Based on the experimental observations and measurements, the varia-tion in pool–point bar locations could be interpreted to that the hydraulic and morphologic properties through the meander evolution were varied during the time causes the variations in the patterns of the pool-point bar formations accordingly. The developed formula was verified by using another set of the experimental data and tested with three statistical indica-tors. The predicted results indicated that the proposed formula had high reliability for practical estimation of the pool-point bar location. This reliability was tested by the statistical indicators, where the less values have been resulted for bias andmean absolute error (MAE), 0.0004 and 0.0110 respectively, whereas the higher values 0.935 and 0.930 are achieved for the Nash–Sutcliffe efficiency (NSE) and the determination coefficient R2, respectively.}, type={Artykuły / Articles}, title={Identifying the pool-point bar location based on experimental investigation}, URL={http://journals.pan.pl/Content/114833/PDF-MASTER/Maatooq%20Hameed%20523.pdf}, keywords={experimental investigation, meander evolution, morphologic properties, pool-point bar, river sand}, }
