Estimating the flash flood quantitative parameters affecting the oil-fields infrastructures in Ras Sudr, Sinai, Egypt, during the January 2010 event

Abstract

This paper aims to quantify the hydrological parameters for the flash flood event of 17th January 2010 in Sinai using multiple sets of remote sensing data and field work for the nongaged catchments (approximately 2100 sq km) of the wadis affecting Ras Sudr area, which is heavily occupied by numerous oil fields and related activities. The affected areas were visited, and several cross sections of the main active channels were surveyed to estimate the peak discharge rates. The Tropical Rainfall Monitoring Mission (TRMM) data have been used to estimate rainfall parameters for the catchments due to the absence of in situ data. The digital elevation model (DEM) of the Shuttle Radar Topography Mission (SRTM) was used to extract the hydrographic data following standard procedures and techniques of the Geographic Information Systems (GIS). Both of the surveyed and extracted parameters for the active channels were integrated into GIS to estimate the runoff parameters using the open-channel flow equation of Manning's. The simulated hydrographs show that the total discharge exceeded 5.7 million cubic meters and the peak discharge rate was 70 cubic meters per second. The mitigation of extreme flash flood is possible by altering the natural flow dispersion over the alluvial fan, and conveying the resulting flows into one adjusted channel.

Assessing Flood Risks in Arid Zones by Linking Remote Sensing Techniques and Gis

“…During this period, the study area was sustainable, in terms of the Egyptian Code for flood danger protection. In addition, a link was established between the GIS program and the HEC RAS program to reflect the inundation maps, where figures (11) and ( 12) are provided to represent the limits of flood inundation with maximum depth and maximum velocities, for a return period of 100 years, respectively.…”

“…Moreover, the effect of high releases downstream of the Assiut Barrage (544.75 km from the Aswan Dam depression) was studied . [ 4 ] Furthermore, hydrological parameters of the flash flood event that occurred on January 17, 2010 in Sinai were measured using multiple sets of remote sensing data and fieldwork of instrumented watersheds [11]. Moreover, the types of errors that cause inaccurate conclusions of hydrological analysis results have been studied [28].…”

Toward an Integrated and Sustainable Water Resources Management in Structurally-Controlled Watersheds in Desert Environments Using Geophysical and Remote Sensing Methods

“…Further, it was ob- Remote sensing (RS) and geographic information system (GIS) have been increasingly used to improve the imitative methods of data collection in geological and environmental applications [10][11][12][13]. The problem of data limitation has been overcome as megascopic observations through available satellite images and digital elevation models (DEM) of different sources and resolutions [14][15][16]. As a main product of the shuttle radar topographic mission (SRTM), the DEM has been widely used for defining watershed characteristics [14,17], such as flow pathways and their confluences/dispersions and the estimation of linear relationship of these networks [13].…”
