Preprint
In this paper is discussed sediment transport as a mechanical process that characterises a natural stream or channel flow regime. The objective of experimental work presented in this paper is to recall and to give another prospect of well-known Meyer-Peter and Müller approach for estimation of Shield’s number (θ_c,θ) in laboratory conditions, and c...
Article
Accurate estimation of velocity distribution in open channels or streams (especially in turbulent flow conditions) is very important and its measurement is very difficult because of spatio-temporal variation in velocity vectors. In the present study, velocity distribution in streams was estimated by two different artificial neural networks (ANN), A...

World experiences reveal that catastrophic floods are posing a serious threat that comes not only from them as extreme events but also as the result of adaptation measures uncertainty, (i.e. dikes). In particularly old dikes constructed earliest at the north part of Albania, during the last floods demonstrated the high uncertainty and weak spots. I...

In this study, artificial neural networks (ANNs) and adaptive neuro-fuzzy inference system (ANFIS) were used to estimate shear stress distribution in streams. The methods were applied to the 145 field data gauged from four different sites on the Sarimsakli and Sosun streams in Turkey. The accuracy of the applied models was compared with the multipl...
Article
The applicability of artificial neural networks (ANNs) and the adaptive neuro-fuzzy inference system (ANFIS) for determination of mean velocity and discharge of natural streams is investigated. The 2,184 field data obtained from four different sites on the Sarimsakli and Sosun streams in central Turkey were used in the study. ANNs and ANFIS models...

Average shear stress is an important parameter for prediction of sediment transport, bank protection and other river engineering problems in natural streams. For this purpose velocity measurements were taken on Kızılırmak River sub branch, named Sarimsakli stream and Barsama station in center of Turkey. Acoustic Doppler Velocimeter (ADV) was used f...
Article
This paper examines the discharge and velocity distributions in natural open channel flows using the entropy theory. Flow measurements were carried out at four different cross‐sections in central Turkey. The mean and maximum velocities at these stations exhibited a linear distribution and the entropy parameter was calculated to be M=1.31. Using thi...

Devolli river is one of the biggest rivers of Albania which is characterized by large stream flow but also during the full stream flow it bring a lot of sediments and this paper consists precisely to calculation rough of sediments transport of this river.It is important to recognize that present conditions in the Devoll valley are not necessarily t...
Article
Density differences may occur because of temperature differentials, suspended sediments, dissolved salts or other chemicals. Most of the large surface reservoirs are stably stratified throughout most, or all, of the year. One of the means of assisting the management is to allow a selective withdrawal from the reservoir. And while an intake is used...
Article
This paper investigates the accuracy of an adaptive neuro-fuzzy computing technique in suspended sediment estimation. The monthly streamflow and suspended sediment data from two stations, Kuylus and Salur Koprusu, in Kizilirmak Basin in Turkey are used as case studies. The estimation results obtained by using the neuro-fuzzy technique are tested an...

In this study, vertical and lateral velocity distribution in a compound channel cross section was mea-sured to investigate kinetic energy and momentum correction coefficients for nine different test dis-charges. Experiments were carried out for subcritical flow conditions and the Froude number (Fr) and depth ratio (Dr) varied between 0.87 and 0.95,...

IIn this paper the capability of two different feed-forward back-propagation neural network algorithms, namely Levenberg-Marquardt and gradient-descent, in solving complex nonlinear problems is utilized for suspended sediment prediction. The monthly streamflow and suspended sediment data from two stations, Palu and Çayağzi, in the Firat Basin in Tu...
Article
Distributions of shear stresses throughout the entire cross-section within the fully developed boundary layer region in both the smooth and rough surfaces of a rectangular open channel flow were experimentally determined. Velocity measurements were taken for two different surfaces and 48 flow conditions with Froude numbers in the range: 0.12 ≤ Fr ≤...

In this paper, boundary layer development was investigated for smooth open channel flow. For this purpose ADV velocity measurements were made at 16 different distances along the channel mid section for four different flow conditions. Both experimental and theoretical methods implemented in the computation of boundary layer thickness. Boundary layer...

Dynamic programming with successive approximation has been used in the past for optimizing multi-reservoir water resources systems. In this study, the State Incremental Dynamic Programming (SIDP) model is developed for energy optimization of multi-reservoir systems. A random file access method is used for reaching initial and intermediate data to c...

Applicability of logarithmic and entropy-based velocity distribution equations is investigated for rough-surface open-channel flow. For this purpose, 24 flume experiments, comprising over 1200 point measurements, are performed for Reynolds number ranging from 3.4.104 to 1.7.105 and aspect ratio from 4.2 to 12.0. The investigated equations have a fl...

First, a numerical algorithm for the friction factor in the Darcy–Weisbach pipe friction head loss formula is developed by an effective linear iteration scheme of the Colebrook–White equation, which precisely determines, with a small load of computations, the friction factor within the ranges of: 0<relative roughness<0.1 and 2×103<Reynolds number<1...

In this study, vertical and lateral velocity distribution in a compound channel cross section was measured to investigate kinetic energy and momentum correction coefficients for eight different test discharges. Experiments were carried out for supercritical flow conditions. Froude number (Fr) was varied between 1.04 and 1.1, as depth ratio (Dr) cha...

The results of model testing of arch and straight deck bridge constrictions are presented. All tests were carried out in a compound flume that consists of a main channel and two symmetric floodplains set at a fixed bed slope. A simple generalized afflux equation is also proposed. The equation which describes the model characterizes the afflux as a...

Using a Laser-Doppler anemometer, mean velocities are measured in developing and fully developed turbulent subcritical smooth open channel flows. Experiments are conducted in a rectangular laboratory channel for 12 different test conditions with Reynolds number ranging from 28,026 to 136,842. From the experiments it is found that the boundary layer...

Determination of flow discharge is very important for different demands such as water management, water supply, irrigation, flood control, ect. There are two classical methods for this purpose from which empirical formulas include much elusiveness and measurement methods require a great amount of time and effort. The introduction of the entropy con...
