Sub-Surface Hydrology Dataset for the Jazira Region of Syria

This sub-surface hydrology dataset complements 13 other datasets as part of a study that compared ancient settlement patterns with modern environmental conditions in the Jazira region of Syria. This study examined settlement distribution and density patterns over the past five millennia using archaeological survey reports and French 1930s 1:200,000 scale maps to locate and map archaeological sites. An archaeological site dataset was created and compared to and modelled with soil, geology, terrain (contour), surface and subsurface hydrology and normal and dry year precipitation pattern datasets; there are also three spreadsheet datasets providing 1963 precipitation and temperature readings collected at three locations in the region. The environmental datasets were created to account for ancient and modern population subsistence activities, which comprise barley and wheat farming and livestock grazing. These environmental datasets were subsequently modelled with the archaeological site dataset, as well as, land use and population density datasets for the Jazira region. Ancient trade routes were also mapped and factored into the model, and a comparison was made to ascertain if there was a correlation between ancient and modern settlement patterns and environmental conditions; the latter influencing subsistence activities. This dataset includes water quality index values for sub-surface hydrology and also maps surface and sub-surface irrigation zones in the Jazira region. Evidence suggests that wells have been dug over the millennia to extract potable groundwater for human and animal consumption. It is feasible that groundwater could also have been extracted to irrigate gardens. Derived from 1:500,000 maps produced for following report: Food and Agriculture Organization (FAO), United Nations. Etude des Ressources en Eaux Souterraines de la Jezireh Syrienne. Rome: FAO, 1966.Sub-surface hydrology map was copied to mylar and scanned to create a polygon coverage. Attribute information includes water quality index values with a range of 0 to 6 with the latter value corresponding to high quality. Subsequently, each polygon was labelled and attributed with the water quality index values. GIS vector data. This dataset was first accessioned in the EDINA ShareGeo Open repository on 2010-06-30 and migrated to Edinburgh DataShare on 2017-02-21.
