Effects of River Inputs on Mediterranean Coastal Shore Line in front of Damietta Estuary

چکیده
HE WATER quality characteristics and some heavy metals cations (Fe, Mn, Zn, Cu and Pb) of Damietta estuary and in front of Mediterranean coastal shoreline were evaluated through four successive cruises (February 2008 to November 2008). Twelve sites were selected from the two sectors. The results obtained showed that serious deterioration of quality of water at Damietta estuary compared with Mediterranean shoreline. The concentrations of major cations and anions increased progressively while moving away from Damietta Estuary to the sea which reflect the effect of seawater intrusion into estuary. Contrarily, nutrient salts values in the estuary showed elevated values due to heavily polluted waste water poured into estuary where the nutrient salts content of the Mediterranean Sea water depend on its levels in Damietta Estuary. The distribution order of heavy metals concentrations in water samples was Fe > Mn > Pb > Zn > Cu > Cd.

A Model of Non-Stationary Time-Series to Predict Surface Salinity Off-Shore the Columbia River
The Columbia River discharge plays a central role in North-East Pacific Ocean coastal ecosystem dynamics. A model is developed to predict non-stationary surface-salinity time-series in the North Pacific Ocean off-shore the Columbia River. The model takes wind velocities and Columbia River discharge as inputs only. Wind velocities are converted to smoothed wind stresses which are then integrated...

Introduction Due to the different geomorphological and morph dynamic forces of the coastal area, they form different areas. Each of these areas requires its own coastal management. While in our country, coastal management is done without considering the characteristics and coastal characteristics of each coast. In this study, in order to classify coasts and determine coastal cells, morph dynam...

A metal-enriched seawater plume entering the western Mediterranean Sea through the Strait of Gibraltar originates 300 km to the west in the Rio Tinto estuary of southwestern Spain. Mining of Rio Tinto ore, one of the largest metal-rich sulfide deposits in the world, started well before Roman times. Contemporary Rio Tinto waters draining the region are highly acidic (pH 2.5) with dissolved cadmi...
متن کاملWastewater influences nitrogen dynamics in a coastal catchment during a prolonged drought
Ecosystem function measurements can enhance our understanding of nitrogen (N) delivery in coastal catchments across river and estuary ecosystems. Here, we contrast patterns of N cycling and export in two rivers, one heavily influenced by wastewater treatment plants (WWTP), in a coastal catchment of south Texas. We measured N export from both rivers to the estuary over 2 yr that encompass a seve...
