Investigation of the groundwater modelling component of the Integrated Water Flow Model (IWFM)
Ercan, Ali; Dogrul, Emin C.; Kadir, Tariq N. (2016-01-01)
The Integrated Water Flow Model (IWFM), developed by the California Department of Water Resources, is an integrated hydrological model that simulates key flow processes including groundwater flows, streamflow, stream-aquifer interactions, rainfall-runoff and infiltration. It also simulates the agricultural water demand as a function of soil, crop and climatic characteristics, as well as irrigation practices, and allows the user to meet these demands through pumping and stream diversions. This study investig...
Investigation of combustion characteristics of biomass and coal mixtures in a circulating fluidized bed combustor
Varol, Murat; Atımtay, Ayse; Department of Environmental Engineering (2013)
In this study, combustion and co-combustion tests of Bursa/Orhaneli lignite with two biomass fuels (olive cake and woodchips) were carried out in a laboratory scale Circulating Fluidized Bed (CFB) combustor, 6 m high and 108 mm inside diameter, in order to investigate the effect of excess air ratio (l), secondary air ratio (SAR) and location of secondary air injection along the combustor wall on the emissions. Optimum l and SAR was determined for each test. The flue gas emissions were compared with limits i...
Investigation of passive sampling of no2 and o3 in ambient air and determination of the effects of meteorological parameters to the uptake rate
Bayındır, Elif; Tuncel, Semra G.; Department of Chemistry (2008)
In this study NO2 and O3 gases which are the secondary pollutants in ambient air were sampled with designed passive tubes. The collected samples were extracted for UV-VIS spectrometric analysis. NO2 gases were converted to NO2- ions by extracting with water and then this solution was colored with Saltzman reagent (5:1 sulfanilamide and N-(1 naphthly)-ethlyene-diamine dihydrochloride). Then the absorbance of the solution was measured at 537 nm. O3 was extracted with 3-metyl-2-benzothiazolinone hydrozone hydr...
Investigation of the effects of uncertainties of inflow hydrograph and dam breach geometry on outflow hydrograph
Gödek, Neslihan Pınar; Yanmaz, Ali Melih; Çalamak, Melih; Department of Civil Engineering (2021-11)
Precise breach outflow hydrograph is crucial for the accurate determination of the flood damage and cost at the downstream region. Precise flood inundation modeling is based on the use of a realistic breach outflow hydrograph as an input. Therefore, comprehensive modeling is essential for an accurate description of breach hydrograph. This study evaluates the effects of dam breach parameters and inflow hydrograph on the peak breach outflow utilizing a probabilistic dam breach model. An experimental model was...
Investigation of factors affecting coke strength after reaction (CSR) and developing a statistical model for CSR prediction
Ünsal, Barış; Arol, Ali İhsan; Department of Mining Engineering (2018)
This study was aimed at investigating the coke strength after reaction (CSR) prediction before coke production by regression modelling. Initially, quality parameters of studied coals, namely Australian, American and Canadian coals, were categorized to understand fluctuation in the parameters. Parameters studied consist of proximate analysis, physical properties, rheological properties, ash chemistry, petrographical analysis and coke quality parameters of the coals. After understanding remarkable difference ...
