GIS and remote sensing as tools for conducting geo-hazards risk assessment along Gulf of Aqaba coastal zone,Egypt 总被引:2,自引:0,他引:2
Satellite remote sensing data, in addition to Geographic Information Systems (GIS), offers an excellent alternative to conventional
mapping techniques in monitoring and mapping of geo-hazards areas. One of the most sustainable development projects in Egypt
has been accomplished in Sinai, especially along and around the Gulf of Aqaba and the Gulf of Suez. Variations along the coastal
zone of the Gulf of Aqaba have been identified through the analysis of multi-temporal satellite images with the aid of GIS
analysis. The study area is subject to rapid and increasing changes in land-use/land-cover that resulting from natural and
human activities such as flash flooding, seismic activity, landslides, and tourist and urban activities. This is in addition
to the construction projects of roads, ports, PowerStation stations, mineral exploration, beaches, and tourist villages resulting
from major environmental impacts. The current study aims to use Remote Sensing and GIS tools to investigate, monitor, and
assess geo-hazards through the building of a geographical database. Several techniques have been developed over the last decade
mostly to study the geological and geomorphologic characteristics of the terrain; land-use and land-cover changes. These are
based on satellite imagery and Digital Elevation Models (DEM) to determine the topographic features, and geo-hazards maps.
It is concluded that integrated approaches to monitoring can successfully be used to assess the environmental impacts along
the Gulf of Aqaba coastal zone. 相似文献

In this paper, a cross-shore profile evolution model, Uniform Beach Sediment Transport-Time-Averaged Cross-Shore (UNIBEST-TC),
is used. The model was developed at WL/Delft hydraulic laboratory in the Netherlands. The model is used to predict wave height
in a barred beach (Egmond site, The Netherlands) and the results show that there is a good agreement between the measured
and predicted values by the model. In the present study, Morlet wavelet is used to distinguish the breaking waves; it is integrated
over frequency to provide the temporal variation of localized total energy. The study shows that the local peaks of the energy
densities correspond to the events of wave breaking in the predicted–wave time series. Furthermore, the wave energy distribution
shows a tendency to decrease in the off-shore direction of the inner bar. 相似文献

Potential for internal loading by phosphorus based on sequential extraction of surficial sediment in a shallow Egyptian Lake 总被引:1,自引:0,他引:1
Maha Ahmed Mohamed Abdallah 《Environmental monitoring and assessment》2011,178(1-4):203-212
The fractionation of phosphorus (P) in shallow Lake Maryout surficial sediments was investigated in order to understand its potential availability in relation to the eutrophication status of this lake. The rank order of P fractions was NaOH-P > HCl-P > NH4Cl-P > BD-P. The metal oxide-bound P (NaOH-P) averaged 43% in this hypereutrophic lake and would be potentially available under low oxygen conditions. The highly available, loosely sorbed P (NH4Cl-P) represented 20% of the sedimentary inorganic P on average, while the reductant P (BD-P) averaged 15% and is also considered highly available under low oxygen conditions. The less available calcium-bound P (HCl-P) represented 22% of sedimentary inorganic P. Lake Maryout exhibits high potential for release of P from sediment in forms available to algae, which is undesirable for eutrophication control. The range of potentially available P in tested sediments was 1,541 to 3,990 mg/kg (ppm), a very high quantity capable of supporting algal blooms independent of external loading. 相似文献
