Study The Seasonal Fluctuations of Groundwater Characteristics in Al-Raudhatain And Umm Al-Aish Depressions, North Kuwait
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 1
Abstract
The role of groundwater in north Kuwait is expected to be doubled in the near future. The fresh groundwater lenses in the Quaternary Aquifer in Al-Raudhatain and Umm Al-Aish Depressions (QARUAD) receive special attentions of the government and different investment authorities for agricultural development and construction new communities. Expanding the development of new communities within the limited low flat desert surfaces in north Kuwait has started to face the continuous growth of population. The specific objectives of this study were to detect the dynamics of groundwater level and salinity in wet and dry season; and to determine the relationships among the groundwater level, salinity content, and climate factors. The materials used in this paper were collected through carrying out 12 field trips in QARUAD during the period 2015-17. Moreover, network of 120 observation and dug wells was chosen for seasonally periodic recording of groundwater levels and hydrogeochemical routine analysis and cluster analysis. The results showed that the groundwater moves generally from the SW to the NE towards the Arabian Gulf. Direct recharge through the rainfall, faults and lateral flow from the adjacent aquifers are the acceptable source of the recharge to QARUAD. The change in groundwater salinity may attribute to the seasonal rainfall, lithologic composition and structural impacts. The relation between TDS and different major ions are statistically analyzed. Four principal components were extracted from chemical data to explain the major sources and processes responsible for chemical characteristics of groundwater. Cluster analysis showed that silicate weathering, agricultural runoff (fertilizer input), municipal wastewater infiltration play a vital role in the enrichment of ionic constituents. It is concluded that that the majority of the samples are good to permissible for drinking purpose which reflects a good chance for agriculture and urbanization development. An integrated water management to the most fresh upper zone of QARUAD and detailed subsurface study before any reclamation activities are recommended.
