The Application of Two-point Method for Estimation of Flow Hydrodynamic
Parameters in Mountainous Cobble-Bed Rivers

Abstract
The study of mountainous rivers is recently considered by hydraulic researchers. Ten cross sections of a
cobble-bed river, Behesht Abad, located in the central Iran were applied in this study. The distribution of
velocity profile in cobble-bed and accuracy of two-point method to estimate the parameters of mean velocity and
shear velocity were investigated and then the values of flow resistance were evaluated. Shear velocity was
calculated by two-point method, and velocity profile and the results were compared by the parabolic and the
boundary layer characteristics methods to predict flow resistance function. Results reveal that velocity profiles
present S-shape and logarithm distributions. Also the values of mean velocity, shear velocity and flow resistance
function calculated by two-point method can be presented with 94.6, 85.6 and 84 per cent accuracy, respectively.
The results of this study can be extended to apply and to predict flow resistance for other mountainous rivers in
Iran.

The hydrodynamic flow field in streams and rivers influences many ecological processes including organism dispersal, habitat use, and resource acquisition. Understanding the linkages between hydrodynamic and ecological processes is essential for developing effective restoration and management tools. Despite the pervasive influence of flow velocity and turbulence, the details of natural stream flow fields as they apply to ecological concepts are poorly understood. In this study, velocity and turbulence distributions were investi- gated at two spatial scales using an acoustic Doppler velocimeter. The measurements were collected in two cobble-bed rivers with mean depths of approximately 0.5 m, relative roughness values between 0.12 and 0.33, and streamflow rates of 1.5 and 3.1 m3/s. The analysis included mean velocity, Reynolds shear stress R, turbulence intensity TI, and turbulent kinetic energy TKE vertical profiles and horizontal heterogeneity collected in riffle, run, and pool habitat units. The measured profiles were compared with previously reported semiempirical equations. The logarithmic profile reasonably described the vertical velocity profiles. However, the observed TI, TKE, and R profiles deviated noticeably from the semiempirical relationships. Velocity magnitude and cross-correlation coefficients revealed strong spatial heterogeneity at both the reach and fine scales. Spatial heterogeneity was also observed in TI and TKE data, but to a lesser degree. The results provide a novel description of flow field characteristics in cobble-bed rivers while demonstrating techniques for measuring velocity and turbulence distributions in natural streams in the context of an ecohydraulics study.

The hydraulics of overland flow on rough granular surfaces can be modelled and evaluated using the inundation ratio rather than the flow Reynolds number, as the primary dimensionless group determining the flow behaviour. The inundation ratio describes the average degree of submergence of the surface roughness and is used to distinguish three flow regimes representing partially inundated, marginally inundated and well-inundated surfaces. A heuristic physical model for the flow hydraulics in each regime demonstrates that the three states of flow are characterized by very different functional dependencies of frictional resistance on the scaled depth of flow. At partial inundation, flow resistance is associated with the drag force derived from individual roughness and therefore increases with depth and percentage cover. At marginal inundation, the size of the roughness elements relative to the depth of flow controls the degree of vertical mixing in the flow so that frictional resistance tends to decrease very rapidly with increasing depth of flow. Well-inundated flows are described using rough turbulent flow hydraulics previously developed for open channel flows. These flows exhibit a much more gradual decrease in frictional resistance with increasing depth than that observed during marginal inundation.

In 1965, Rouse critically reviewed hydraulic resistance in open channels on the basis of fluid mechanics. He pointed out the effects of cross-sectional shape, boundary nonuniformity, and flow unsteadiness, in addition to viscosity and wall roughness that are commonly considered. This paper extends that study by discussing the differences between momentum and energy resistances, between point, cross-sectional and reach resistance coefficients, as well as compound/composite channel resistance. Certain resistance phenomena can be explained with the inner and outer laws of boundary layer theory. The issue of linear-separation approach versus nonlinear approach to alluvial channel resistances also is discussed. This review indicates the need for extensive further research on the subject.

The velocity distributions in both steady and unsteady flows in a gravel-bed flume were measured with micropropellers. It is shown that, for steady flows: the additional term Br in the velocity distribution equation is a function of both the relative roughness and the Froude number, and while the velocity fluctuation V value gets its maximum of about 0.1 near the bottom, the maximum velocity fluctuation u value is around 1. For unsteady flows: in simulation of the hydrographs in natural mountain rivers, two hydrographs were created and each one repeated for more than 100 times in the laboratory; for an equal water depth, the velocity in the rising branch is generally larger than that in the falling branch; the velocity profiles are analyzed; the friction velocity, calculated from the St. Venant equation, is also larger in the rising branch and the time lags among the water discharge, the water depth, the vertical mean velocity, and the friction velocity are observed.

This paper presents results of the friction factor of cobble-bed and boulder-bed rivers based on 23 field measurements in three mountainous rivers in Iran. Results reveal that features of our measured velocity profiles in boulder-bed rivers in mountainous region do not present a specific shape but illustrate specific pattern in cobble-bed rivers. This difference is attributed to scale effect of relative submergence. It is found that the relative submergence in cobble and boulders-bed rivers is the only key parameter that influences friction factor estimation and other parameters such as particle Froude number and Froude number have few impacts on flow resistance of cobble-bed and boulder-bed rivers. The proposed relationship for estimation for the friction factor should be useful for large coarse-bed rivers.

This study extends the earlier contribution of Julien and Wargadalam in 1995. A larger database for the downstream hydraulic geometry of alluvial channels is examined through a nonlinear regression analysis. The database consists of a total of 1,485 measurements, 1,125 of which describe field data used for model calibration. The remaining 360 field and laboratory measurements are used for validation. The data used for validation include sand-bed, gravel-bed, and cobble-bed streams with meandering to braided planform geometry. The five parameters describing downstream hydraulic geometry are: channel width W, average flow depth h, mean flow velocity V, Shields parameter *, and channel slope S. The three independent variables are discharge Q, median bed particle diameter ds, and either channel slope S or Shields parameter * for dominant discharge conditions. The regression equations were tested for channel width ranging from 0.2 to 1,100 m, flow depth from 0.01 to 16 m, flow velocity from 0.02 to 7 m/s, channel slope from 0.0001 to 0.08, and Shields parameter from 0.001 to 35. The exponents of the proposed equations are comparable to those of Julien and Wargadalam 1995, but based on R2 values of the validation analysis, the proposed regression equations perform slightly better.
