Gas phase pollutants (O-3, NOx and SO2) suspended particulate matter (SPM), and major ions in aerosols were measured for 12 month period at a mountainous site of northwestern Turkey which is suffering from severe forest decline. Gaseous pollutants, SPM and meteorological parameters were measured in hourly basis with automated analyzers. Aerosol samples were collected daily. The long and short term trends in the concentrations of the measured parameters were investigated in order to understand the causes of the observed concentrations of these pollutants. Higher concentrations of O-3 during summer months were consistent with the higher photochemical production from precursor gases (NOx) with increased solar flux. The diurnal variations of O-3 and NO2 were 27 and 2.3 ppb respectively during summer. The diurnal pattern of O-3 NO, NO2 and SPM describes a photochemical smog scenario. Sulfate makes up about 30% of the total analyzed aerosol mass. A lower pH associated with a high level of SO42- and NO3- in aerosols is an indication of acid deposition. Wind sector analysis indicated the largely contributing source regions to be located in the southern and northern direction of the sampling site which is Bursa city, local industries and the nearby power plant.

Numerical simulation of infiltration and evaporation for unsaturated infinite soil slopes
Kenanoğlu, Melih Birhan; Toker, Nabi Kartal; Huvaj Sarıhan, Nejan; Department of Civil Engineering (2017)
Rainfall triggered landslides are common threat in many regions of the world and cause loss of lives and properties. These are shallow failures (typically 3-5 m depths from the ground surface) that occur along a plane parallel to the ground surface where the groundwater level is located at significant depths below, and they are triggered after a heavy rainfall in a short time or after days of lower intensity rainfall (Huvaj et al., 2013). Considering a failure plane oriented parallel to the ground surface, ...
Chemical composition of rainwater at EMEP station in Ankara, Turkey
Topcu, S; Incecik, S; Atımtay, Aysel (2002-11-01)
The chemical characteristics of rainfall and its seasonal variation at the EMEP (The Cooperative Programme for Monitoring and Evaluation of the Long-Range Transmission of Air Pollutants in Europe) station located in Cubuk, Ankara were studied for the period between September 1994 and December 1996. The station is located in a rural area about 50 km north of Ankara and is considered as a background station for air pollution. The rainwater samples collected were analyzed for pH, major ions concentrations and ...
Measurement of NOx, SO2, SPM and O3, at a high altitude station in the northwestern Turkey
Tuncel, Semra; Baykal, Abdülhadi; Tuncel, Süleyman Gürdal; Özer, Ulviye (1994-01-01)
Temporal variation of NO, NO2, SO2, SPM (suspended particulate matter), and O3 were measured at a high altitude station in the northwestern part of Turkey. The long‐ and short‐term trends in the concentrations of measured parameters were investigated to understand sources contributing to the observed concentrations of these pollutants. Higher concentrations of O3 during summer months were consistent with higher photochemical production with increased solar flux. Seasonal patterns observed in other parameter...
MEASUREMENT OF NOX, SO2, SPM, AND O-3 AT A HIGH-ALTITUDE STATION IN NORTHWESTERN TURKEY

Estimation of Rainfall Runoff Relation Using HEC HMS for a Basin In Turkey
Akay, Hüseyin; Baduna Koçyiğit, Müsteyde; Yanmaz, Ali Melih (null; 2016-07-29)
This study deals with the investigation of the rainfall-runoff relation of a watershed inWestern Black Sea Region, Turkey. The aim is to perform a hydrological assessment for a watershed located near Bartın city. The basin is very mountainous and forestry with increasing urbanization. The hydrological parameters of the basin are likely to be altering due to possible changes in climate and precipitation patterns. Land-use/cover changes owing to human activities and urbanization in the area also contributes t...
