River water quantity and quality monitoring in an agricultural basin in north greece [link]Paper  abstract   bibtex   
The monitoring effort of Lissos River, located in Rhodope County, Thrace, North Greece, is presented. The river springs from Rhodope mountains and discharges into the Thracean Sea in the North Aegean, in an area protected by the Ramsar Convention. There are point and non-point pollutant sources in Lissos watershed resulting from human activities. Monitoring of Lissos River is essential for two reasons: first its water is used for irrigation of cultivated fields, and second it is included into the EU "Natura 2000" network. For the purposes of this study, a data collection program was established, aiming to collect data useful for the evaluation of the water quality of the river and its trophic state. The data include the following: (a) hydrologie (i.e., precipitation, air temperature, etc.) in a total of 2 stations over the watershed; (b) streamflow and sediment transport (i.e., cross-sectioning, velocity, suspended sediment, etc.) in a total of 7 stations in various torrents and in the main river course, at a frequency of ten days; (c) Electrical Conductivity (EC), pH, Dissolved Oxygen (DO) and Temperature (T) measured in situ simultaneously with discharge measurements; and (d) water samples collected and analyzed for the determination of Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solids (TSS), nitrates, nitrites, ammonium, total phosphorus (TP), ortho-phosphates (OP), alkalinity and various anions (i.e., SO41 , Cl-) and cations (i.e., Na +, K+, Mg+2, Ca+2). Monitoring results showed influence on the EC values and nitrogen and phosphorus concentrations in the tributary of Lissos where a wastewater treatment plant discharges its effluent. The one-way between groups ANOVA showed that there were statistically significant differences of mean values of measured parameters (i.e., BOD, COD, TP, Cl-, SO4-2 etc.) between various stations of the river, indicating pollutant sources. The trophic state of Lissos was found eutrophic due to increased concentrations of nutrients, indicating the need for management measures in order to improve river water quality. The water quality of Lissos River, for irrigation use, was found satisfactory and suitable for almost all crops.
