The objective of this study was to develop quantitative stochastic methods to assess effects of land-disposed E&P waste on groundwater quality. A computer model was developed to assess the probability of groundwater contamination from salts and oily waste constituents disposed by landspreading or in waste pits. The model considers leaching of chemicals from the waste zone over time until the constituent mass is depleted. It considers volatilization of organics for landspreading. Water flow is controlled by the net infiltration rate (rainfall minus evaporation and surface runoff), except for lined pits, in which flow may be limited by a low permeability layer. The program models one-dimensional convective-dispersive transport of dissolved constituents through the unsaturated zone and three-dimensional transport in groundwater zone. Organic constituents are subject to adsorption and biodecay. A Monte Carlo method is used to determine the probability distribution of maximum constituent concentration at receptor locations, given probability distributions of hydrogeologic and waste properties.

Computer assisted analysis of flow over spillway chutes Kıranoğlu, Meriç; Yanmaz, A. Melih.; Department of Civil Engineering (2019) In this study, a literature review is conducted in terms of assumptions, approaches, and various calculation methods used for the analysis of flow over conventional and stepped type spillways. In guidance of this review, a software is developed to perform such analyses with the set of given data by the user, and display results with some tables and figures. To this end, water surface profile over the spillway face is determined considering air entrainment process, pressure distribution over the crest under ...
Degradation of decabromodiphenyl ether (BDE-209) in microcosms mimicking sediment environment subjected to comparative bioremediation strategies Demirtepe, Hale; İmamoğlu, İpek (Elsevier BV, 2019-03-01) The aim of this study was to examine bioremediation strategies for BDE-209 contaminated sediments. Sediment microcosms were established to observe anaerobic debromination of BDE-209 under conditions representing three bioremediadon strategies: biostimulation, bioaugmentation and natural attenuation. To simulate biostimulation, a defined mineral medium containing both a carbon source (sodium formate) and electron donor (ethanol) was added into sediments. Bioaugmentation was established by enrichment of the s...
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...
Assessment of buried pipeline performance during the 1999 Duzce Earthquake Yargıcı, Volkan; Çetin, Kemal Önder; Yücemen, M. Semih; Department of Civil Engineering (2003) The goal of this study is to develop probabilistically based empirical correlations for seismic performance assessment of buried pipelines. Within the scope of these research efforts, pipeline performance case histories have been compiled from Duzce city after Duzce earthquake. The characteristics of Duzce water supply and distribution system with the earthquake damage on the system were studied. Correlations of the damage patterns with the water distribution system, earthquake and geotechnical characterist...
Assessment of quality and quantity of leachate from the municipal solid waste landfill of bursa Akyol, Selin; Ünlü, Kahraman; Department of Environmental Engineering (2005) In this study, regularly measured long-term leachate data from Bursa Municipal Solid Waste Landfill (MSWL) were analyzed using conventional statistical, time series and factor analyses to investigate in detail the temporal variability of leachate quality and quantity, trend, randomness, seasonality and the auto- and cross- correlations of leachate pollutants. Evaluating the results of data analyses, leachate management recommendations, including sampling strategies in monitoring programs and treatment alter...
