K.F. UBEID 134Figure 5. Textural patterns along the beach sands.This study’s data analysis showed further that the percentage of fine and medium-grainsand increased toward the north and the percentage of coarse-grained sand increased toward thesouth, as Figure 7 depicts graphically. This indicates that the sand grains become segregated due totheir size as they move northward.Figure 6.

135SAND CHARACTERISTICS AND BEACH PROFILES OF THE COAST OF GAZA STRIP, PALESTINEFigure 7. Significant correlations of grain size distributions along the beach sands.ConclusionsThis study’s survey of the Gaza Strip’s coastal zone found that its beaches tend to benarrower in its middle and north than in its south and its northernmost stretch. An exception isthat the beach tends to be wide south of Gaza seaport in its middle stretch due an increase in thedepositional rate and in the rate of erosion north of it.The slope of the beach profile along the coastline varies from a few degrees to 90 degrees.The height of the sea cliffs of the coastal ridge is higher in its middle and northern stretches thanin the south, where it dies out into sand dunes.All of the Gaza Strip’s beaches are sandy. Longshore currents transport these sands alongthe eastern shore of the Mediterranean Sea from the Nile delta. This study’s analysis of 36 samplesfrom 12 locations along these beaches found that the sand grains become segregated as they movefrom south to north, becoming increasingly fine as they go. They are in general predominantlymedium grained. On most of the beaches they are moderately well sorted, due mainly to theactions of marine currents, waves, and tides.ReferencesBartov, Y., Arkin, Y., Lewy, Z., and Mimran, Y. 1981.
