The surface drainage of an irrigation area is concerned with the collection and removal of storm runoff and excess water from irrigation applications. The engineering problem is to determine the shape, crosssectional area and slope of a stable channel. A reliability-based design, which addresses and treats possible uncertainties associated with the design parameters, is of importance as it leads to realistic decision-making. In this paper, a reliability-based assessment of erodible channel capacity based on the regime concept is carried out in an example using the Advanced First Order Second Moment formulation and the Monte Carlo simulation technique. A sensitivity analysis is also carried out to observe the effects of coefficient of variation and probability distributions. The results obtained from both approaches are found to be in relatively good agreement.

Assessment of trophic status of the northeastern Mediterranean coastal waters: eutrophication classification tools revisited Tuğrul, Süleyman; Özhan, Koray; Akçay, İsmail (2019-05-01) The Eastern Mediterranean and its Cilician Basin offshore waters have oligotrophic features with low nutrient concentrations, low primary production, and high water transparency. However, the wide shelf area of the Cilician Basin is subject to contaminated river inflows with enhanced nutrient loads and direct discharges of urban wastewaters of southern Turkey, leading to develop local eutrophic/mesotrophic conditions in the inner sites of Mersin and Iskenderun Bays on the Cilician Basin. For the assessment ...
Reliability assessment in detention basin design Yanmaz, Ali Melih (1998-08-07) A flood detention basin is one of the structural measures used for the mitigation of floods. Its design consists of determining the required flood storage and the dimensions of bottom outlet(s) and overflow spillway. Hydraulic performance of a detention basin is dictated with the achievement of the desired degree of attenuation which is affected by storage and capacities of outlet facilities. In this paper, a reliability based model is presented for the preliminary design of flood detention basins having du...
Determination of optimum rack angle of tyrolean type water-intake structures Melek, Abiddin Berhan; Göğüş, Mustafa; Department of Civil Engineering (2017) Tyrolean weir is known as an effective device to separate major part of sediment from the main channel flow in order to provide required sediment-free water discharge for run-off river hydropower plants. Basically, in the design of Tyrolean weirs, the main concern is to divert at least the design discharge of the facility while it permits to enter the minimum amount of bed-sediment to the system. In this study, water and sediment capture rates of Tyrolean type water-intake structures were investigated for a...
Numerical solution to kinematic wave equation for surface runoff analysis using satellite based DEM data Yıldırım, Hasan Hüseyin; Aydın, İsmail; Department of Civil Engineering (2020-9) Modeling of rainfall runoff over large catchment areas is a critical step in flood analysis to estimate the time-wise variation of discharge at the outlet of hydrological basin. Outlet hydrograph of a basin is generally estimated using empirical formulations based on measurements from previous rainfall events. However, these empirical methods may not correctly model the surface flow dynamics over large and complex geometries. In this study, a fully distributed numerical model is developed that can deal with...
Numerical modeling of seawater groundwater relationships in the Selçuk sub basın, İzmir Turkey Hassan, Abubakr; Çamur, Mehmet Zeki; Department of Geological Engineering (2004) Seawater-fresh groundwater natural equilibrium conditions in the aquifers of the Selçuk sub-basin may be disturbed by the discharge occurred during the past 30 years in order to supply water for irrigation and domestic purpose usage. Two dimensional density dependent cross sectional saturated flow and solute transport simulations were carried out to determine whether seawater intrusion has occurred in the Selçuk sub-basin due to the imposed discharge or the determined salt-water in the western section of th...
