In this study, numerical analyses of newly proposed grated inlet system for small roads are carried out. The model is based on a setup constructed in Hydromechanics Laboratory of METU. The physical model which is a rectangular channel of 0.9m width acts as a small road and continuous transverse grate system is installed as an inlet structure. The physical conditions were modeled by using Flow 3D software. The rates of the intercepted flows are measured and compared with the results of experimental data collected previously. In addition, channel capacity of the system has increased in numerical model in order to see behavior of the system with the higher amounts of flow rates. The efficiencies of continuous transverse grate are calculated with the various amounts of flow rates and their relations with total flow rates and Froude numbers are demonstrated.

Laboratory investigation of hydraulic efficiency of transverse grates in roads
Özbey, Cumhur; Tiğrek, Şahnaz; Department of Civil Engineering (2015)
In this study, hydraulic efficiency of transverse grated inlet systems to be used in small roads is experimentally investigated. For this purpose, an existing experimental setup in the Hydromechanics Laboratory of METU is utilized. Three sets of experiments are conducted in order to examine the relationship between the total flow rate and the grate efficiency with respect to several parameters. In the first set, the interdependence of the void ratio and grate efficiency is investigated. In the second set of...
Comparative study on sediment transport equations for delta formations in reservoirs
Pulcuoğlu, Başar; Tiğrek, Şahnaz; Department of Civil Engineering (2009)
In this study, a qualitative and comparative investigation on sediment transport equations used in prediction of rserevoir sedimentation is presented. 32 sediment transport equations, which are selected by literature review on sand and gravel size ranges, grouped according to the median particle sizes on which their derivation based. In order to compare these equations computer program DELTA, which is a one dimensional simulation program developed by Graf and Altınakar (1998) for the prediction of delta for...
Live load distribution in integral bridge girders
Erhan, S.; Dicleli, Murat (2010-07-15)
In this study, live load distribution formulae for the girders of single-span integral abutment bridges (IABs) are developed. For this purpose, two and three dimensional finite element models (FEMs) of several IABs are built and analyzed. The analyses results are then used to development of live load distribution formulae to estimate the girder live load moments and exterior girder live load shear for IABs with prestressed concrete girders.
Methodology for tunnel and portal support design in mixed limestone, schist and phyllite conditions: a case study in Turkey
Koçkar, Mustafa Kerem; Akgün, Haluk (Elsevier BV, 2003-02-01)
The purpose of this study is to present a methodology for tunnel and support design in mixed limestone, schist and phyllite conditions through investigating two highway tunnel case studies that are located along the Antalya-Alanya Highway in southern Turkey. The main lithologies of the project area are regularly jointed, recrystallized limestone and the weak lithologies of the schist unit (i.e., pelitic schist, calc schist, graphitic phyllite and alternations of these lithologies). A detailed geological and...
Live Load Distribution Formulas for Single-Span Prestressed Concrete Integral Abutment Bridge Girders
Dicleli, Murat (American Society of Civil Engineers (ASCE), 2009-11-01)
In this study, live load distribution formulas for the girders of single-span integral abutment bridges (IABs) are developed. For this purpose, two and three dimensional finite-element models (FEMs) of several IABs are built and analyzed. In the analyses, the effects of various superstructure properties such as span length, number of design lanes, prestressed concrete girder size, and spacing as well as slab thickness are considered. The results from the analyses of two and three dimensional FEMs are then u...
