The objective of this article is describing the changes of the coastline shape during the time period extended between 1973-2014. the coastal zone is very special because it occur at the interface between the three major natural systems at the earth surface atmosphere, ocean and land surface. Geomorphological factors operating in all three of these systems are responsible for shaping the coastal zone, and the interaction between the three different sets of processes makes the coastal zone an extremely dynamic one. At present, a wide range of tools and techniques are available to help us to study the evolution of coastline during the time intervals determined by the available data, and thus become our ability to predict future changes. improve our understanding of the geomorphological processes affect the coastal zone allow us to minimize their effects, and use this knowledge in the development of comprehensive coastal zone management planning.

The research had studied the qualitative and quantitative compositions and the distributions of fish caught from Al Qandil river estuary during the period Jan. – Dec. 2014. In addition, some morphometric parameters of mullets and rabbitfish finger lings، the abundances، periods of presence in various places of the estuary، vitality and mortality rates were studied.
In this study the concentration of (Cu, Cr, Cd, Fe, Mn, Ni, Zn , Pb ,V &Co) in some sedimentary columns and pore-water extracted from the estuary of Al-Kabeer alshemali river was determined during four seasons .the concentrations of these metals w ere determined using atomic absorption spectroscopy (AAS). The columns were cut into slices with 2cm of thickness ,the pore water at every slice was extracted using centrifugation (7000 r/min).the results showed that the concentration increased from surface(deep=0cm, rich of O2) up to the 4cm of deep ,then the concentration decreased in deeper slices (down of 4cm,deficiency of O2) and the concentration of Fe and Mn from high ranking ppm. The rest of the items were relatively lower ranking ppb, but Co, Cd and V were low. meat increased the concentration of all these elements in the spring and summer, compared with the values in the winter and autumn, due to increasing human activities on the one hand and the high temperature on the other hand, leading to increased activities of bacterial that leads to the decomposition of organic material that may increase the ratios of these elements in the pore water.
This study deals with the determination of total mercury concentration in the water taken from three sites on Al-Kabeer Al-Shemaly River ( near the industrial area and Al- Damat Lake, and 16 Tishreen Lake), also the effect of some physio-chemical p arameters including: DO, pH, T °C. of water in the three sites was studied. Results showed that the total mercury concentration was low in general, where the medium concentration in the three studied sites was 0.29 ppb and it was less than the permission level of total mercury in the surface water(> 10 ppb), the higher value of the medium concentration of total mercury(0.35, 0.31, 0.21)ppb was recorded in the Industrial Area, Damat Lake, then 16 Tishreen Lake, respectively. For the changes in the total concentration of mercury in the three studied sites during seasons of a year, was higher in Summer comparing with other seasons. The results showed positive correlation coefficient between the total mercury concentration and temperature, pH value, but it was negative with DO in Summer.
This study aimed at determining the fish fauna composition in 16th of Tishreen Lake (Alkabeer Alshimali River). A total of 730 individual fishes were collected between April 2012 and March 2013 from five different sites along the lake /Alsafkoon, W ata-Alsheer, Alkerassat, Mazraet Alsheikh Deeb, and Alaqfaas area/. Our results showed the presence of only six main fish species belonging to three families (Tillapia zillii, Cyprinus carpio, Liza abu,Varicorhinus damascinus, Garra rufa and Garra lamta). The results also showed that Tilapia zillii was the most caught fish, and Wata-Alsheer was the richest site in the lake. These results showed a decrease in the number of fish species and their quantities compared to that in previous studies on the lake.
