Human Impacts on Nile River Morphology
This paper shows the impacts of human interference on Nile River morphology. A roadway culvert was constructed to connect an island on Nile River to the eastern bank of the Nile had altered river morphology in the vicinity of the island. The paper focuses on, 1) the efficiency of the roadway culvert to pass the normal flow, and 2) the impact of the roadway culvert on river morphology. A one-dim...
متن کاملIs solar variability reflected in the Nile River?
[1] We investigate the possibility that solar variability influences North African climate by using annual records of the water level of the Nile collected in 622–1470 A.D. The time series of these records are nonstationary, in that the amplitudes and frequencies of the quasi-periodic variations are time-dependent. We apply the Empirical Mode Decomposition technique especially designed to deal ...
متن کاملMonitoring of pesticides water pollution-The Egyptian River Nile
BACKGROUND Persistent organic pollutants represent about 95 % of the industrial sector effluents in Egypt. Contamination of the River Nile water with various pesticides poses a hazardous risk to both human and environmental compartments. Therefore, a large scale monitoring study was carried on pesticides pollution in three geographical main regions along the River Nil water stream, Egypt. MET...
متن کاملPolychlorinated Biphenyls Water Pollution along the River Nile, Egypt.
Ten polychlorinated biphenyl (PCB) congeners were determined in water samples collected along the River Nile using gas chromatography-electron capture detector (GC-ECD). PCB concentrations ranged from 14 to 20 μg/L, which were higher than those reported in previous studies, indicating serious PCB pollution in the River Nile. PCB congener profiles varied depending on the sampling sties. PCB-138 ...
متن کاملMathematical Formulation for the Nile River Geographical Ontology
Nowadays, the proliferation of geographic information systems has caused great interest in geographical ontologies. Geographical ontologies have been introduced to facilitate knowledge sharing and to assist in recognizing spatial terms employed in a query. In this research the full model of the Nile River geographical ontology has been developed to meet the needs of the recognition of the termi...
