The optimum values for the section variables like channel side slope,bottom width,depth and radius for triangular,rectangular, trapezoidal and circular channels are computed by minimizing the cost of the channel section.Manning ̕s uniform flow formula is treated as a constraint for the optimization model.The cost function is arranged to include the cost of lining,cost of earthwork and the increment in the cost of earthwork with the depth below the ground surface.The optimum values of section variables are expressed as simple functions of unit cost terms.Unique values of optimum section variables are obtained for the case of minimum area or minimum wetted perimeter problems.

Determination of hydraulic parameters of semi-infinite aquifers using Marquardt algorithm Taşkan, Cüneyt; Önder, Halil; Department of Civil Engineering (2004) In this study, transmissivity and storage coefficient of a semi-infinite, confined, homogeneous and isotropic aquifer, where the flow is one-dimensional and linear, are determined using Marquardt algorithm, considering two independent cases: constant drawdown in the adjacent stream; or constant discharge from the aquifer due to pumping at a constant rate. In the first case piezometric head and discharge measurements are utilized. Hydraulic diffusivity, which is the ratio of transmissivity to storage coeffic...
A study on uncertainty-based flood analysis Akpınar, Mustafa Berkay; Akyürek, Sevda Zuhal; Yanmaz, Ali Melih; Department of Civil Engineering (2023-1) A hydraulic model is a collection of mathematical equations that give a simple representation of reality with the inputs obtained from hydrological assessments to estimate flow, flow depth and velocity in channels. Basically, hydraulic models require digital elevation models, Intensity-Duration-Frequency curves, maximum flows from hydrographs, and roughness coefficients from field studies and/or satellite images. Inherently, these major inputs have uncertainties due to the complex nature of the evalua...
Solution of one-dimensional transient flow in fractured aquifers by numerical Laplace transform inversion Dündar, Serdar; Önder, Halil; Department of Civil Engineering (2005) Laplace transform step-response functions are presented for one dimensional transient flow in fractured semi-infinite & finite aquifers. Unsteady flow in the aquifer resulting from a constant discharge pumped from the stream is considered. Flow is one-dimensional, perpendicular to the stream in the confined aquifers. The stream is assumed to penetrate the full thickness of the aquifer. The aquifers may be semi-infinite or finite in width. The Laplace domain solutions are numerically inverted to the real-tim...
The effect of prismatic ruoghness elements on hydraulic jump Evcimen, Taylan Ulaş; Tokyay, Nuray; Department of Civil Engineering (2005) The objective of this study is to determine the effect of different roughness types and arrangements on hydraulic jump characteristics in a rectangular channel. Three different types of roughness were used along experiments. All of them had rectangular prism shapes and that were placed normal to the flow direction. To avoid cavitation, height of roughness elements were arranged according to level of the channel inlet, so that the crests of roughness elements would not be protruding into the flow. The effect...
Simulation of surface waves generated by a rapid rise of a block at the sea bottom Şenol, Nalan; Aydın, İsmail; Department of Civil Engineering (2005) A mathematical model is developed for investigating time dependent surface deformations of a hydrostatic water volume, when it is subjected to a sudden partial rise of the sea bottom. In the model, 2-dimensional, compressible, and viscous Navier-Stokes equations are solved by Marker and Cell (MAC) method. Variable mesh size in both horizontal and vertical directions with a staggered grid arrangement is used. Limited compressibility model is utilized for pressure. Various computational tests are done for the...
