|Title||Subsurface Geological-Geotechnical Modeling of Gaza Strip|
|Title in Arabic||النمذجة الجيولوجية الجيوتقنية اسفل سطح قطاع غزة|
There is a lack of the geotechnical and geological information of Gaza Strip. There are no complete geology geotechnical reports for Gaza Strip but some studies carried out for specific purposes by some researchers, engineering consulting offices, ministries or government authorities such as the Palestinian Water Authority. Most of these researches are special reports and not published, but little of this information has been published. The internal reports and some of the published data for the study area characterized by a degree of uncertainty, needs purification and re-classification and verified the presence of a repeat in some of them need to be an accurate geological description This study was conducted of Gaza Strip, and depend on some physical properties of the surface (soil texture , water content, , density, liquid limit, bearing capacity) to depth 7.5m, and subsurface layers, geological studying of characteristics geological of the layers. 749 boreholes or wells have been collected from Palestinian water authority (PWA) and materials and soil laboratory(MSL) of the Islamic University in Gaza, 547 from PWA and 202 from MSL. The study aimed to Drawing geological and geotechnical sections at different areas in Gaza Strip in forms of 1D and 2D, Determination the geotechnical properties for different rocks for the study area (nature water content, liquid limit, dry density, soil bearing capacity, soil classification, rock texture..), Determine the characteristics (geological / engineering) for the different rocks at different depths, Update geological cross sections in Gaza Strip to identify of subsurface litho logical structure. The results show that the small change happened to the Gaza strip at 0.5m top soil texture, the soil type on the sea side beach areas is sandy pure soil and especially the northern and southern areas, begin to change gradually as we head east to turn into a silt and clay in the south and clay containing calcium in the north area as Beit Hanoun There is relationship between the natural water content of the soil with the soil type in this region at different depths. There is a direct correlation between the liquid limit and moisture content at the same depth. Sub-surface 8 lithological cross sections has been drawn in different locations. The sections presents soil, and rock types along these locations .Some of these proposed sections correlated well with previous sections suggested by others. Data Bank was created as a nucleus for an electronic database using Rock ware program and Google Earth.There is a direct correlation between the liquid limit and moisture content at the same depth. Sub-surface 8 lithological cross sections has been drawn in different locations. The sections presents soil, and rock types along these locations .Some of these proposed sections correlated well with previous sections suggested by others. The study gives recommendation for creating Data bank over the Internet that contains geological and geotechnical characteristics to get them on demand and collect more data to be as for building 3D model using Rock ware software for Gaza strip and adding new data to get more accuracy in description, Selecting new geotechnical characteristics to conduct the same studies and Standardization the geological terminology during drilling wells and description. Merge geological characteristics of the soil, water levels can be integrated to gain more information about water resources with more areas. collected data maps is a very important tool that can be used Determine location of solid waste, building areas, areas for agriculture purposes and assign areas to be used for wastewater treatment plants.
