Nutrient dynamics at the interface between surface waters and groundwaters
1. The surface water/groundwater (SW/GW) interface is a crucial control point for lateral nutrient ̄uxes between uplands and aquatic ecosystems and for upstream/ downstream (longitudinal) processes in lotic ecosystems. 2. Hydrological and biogeochemical dynamics of the SW/GW ecotone are linked to the degree of channel constraint and the sediment characteristics of the ̄oodplain and stream bed. 3....
متن کاملfrom historical facts to geo-political realities: relation between turkey and armenia ( 1915 – 2010)
armenias geopolitics and its historical experience have had a determining impact on the character of its foreign policy .present-day armenia is a small, landlocked country with _11,620 square miles area armenias landlocked nature makes it dependent on the benevolence of its neighbors for access to the outside world a fact that gives it a sense of isolation and vulnerability. as it was indic...
15 صفحه اولApplication of SWAT Model to Simulate Nitrate and Phosphate Leaching from Agricultural Lands to Rivers
In the present study, the amount of nitrate and phosphate leaching from agricultural lands into the Zanjanrood River in Iran was simulated using the Soil & Water Assessment Tool (SWAT) model. The measured average monthly discharges at the Sarcham station were used to calibrate and validate the SWAT model, and the SWAT Calibration and Uncertainty Program (SWAT-CUP) model was applied to perform t...
متن کاملVariations in Nitrate and Phosphate Contents of Waters in the Southwest Caspian Sea
Science and technological developments provide new opportunities to exploit aquatic resource. Hence, it is important to understand biotic and abiotic conditions of aquatic ecosystems. Objective of this Paper is to report findings of the study of nitrate and phosphate contents of water and effects of other physicalchemical parameters in the southwest regions of the Caspian Sea in the spring and ...
متن کاملCapability of Chlorella vulgaris to remove nitrate and phosphate at different concentrations and condition: studied by response surface methodology
In order to study the capability of microalgea Chlorella vulgaris in removal of nitrate and phosphate from water, the effects of initial concentration of nitrate and phosphate and photoperiod were investigated in 20 experiments proposed by response surface methodology. The most effective factors in nitrate removal include initial nitrate concentration, photoperiod and interaction of phosphate-p...
