Analysis and Environmental Studies of MaryutLake, Alexandria, Egypt
The article discusses Maryut Lake, near Alexandria, Egypt, using samples of bottom sediment to examine the conditions and mechanisms of its precipitation bias. The results of this study suggest that changes between different parts of the lake may be due to a variety of deposit-related reasons. With respect to its precipitation, the paper states that the relationship between its sorting (σI) and average size (Mz), and between its sorting (σI) and asymmetry (SkI) grains (pellets) of precipitation, indicate that the materials encompassed in the sediment are mostly fluvial in origin. At this stage the report re-focuses on geographical, geological and meteorological data, and on precipitation-related information. Statistical parameters indicate that the latter range from 0,012 mm to 0,52 mm with an average rate of 0,28mm. The research report also notes that the lake’s average and median diameters are almost identical. Sort samples collected from rainfall range from 0,67 mm to 2,74 mm with an average of 1,80mm (moderate to very poor sediment). Differences in grading imply that the materials comprising its sediments were received from more than one source. Furthermore, the distribution coefficient of collected sedimentary samples varies from 0,74 mm to 2,54 mm with an average of 1,10 mm, which means the lake sediments have an average kurtosis of 1,10 mm.
