The objective of this study is to survey natural resources and to assess environmental changes induced by human activities (industrial, socio-economic, and recreational) and the associated impacts on Manifah and Tanagib coastal zones in eastern Saudi Arabia. A review of the relevant literature was carried out at both the local and regional levels, in order to define the characteristics of the c...

The Um Alhool area in Qatar is a dynamic evaporative ecosystem that receives seawater from below as it is surrounded by sand dunes. We investigated the chemical composition, the microbial activity and biodiversity of the four main layers (L1-L4) in the photosynthetic mats. Chlorophyll a (Chl a) concentration and distribution (measured by HPLC and hyperspectral imaging, respectively), the phycoc...

Mineral dust in the atmosphere has implications for Earth’s radiation budget, biogeochemical cycles, hydrological cycles, human health, and visibility. Currently, the simulated vertical mass flux of dust differs greatly among the existing dust models. While most of the models utilize an erodibility factor to characterize dust sources, this factor is assumed to be static, without sufficient char...

The Mesopotamian Plain is part of the Mesopotamia which extends for vast area bigger than plain. plain almost flat and lowland, has clearly defined physiographic boundaries with other surrounding provinces. a huge accumulation geomorphologic unit, where fluvial, lacustrine, Aeolian landforms prevail; fluvial units being abundant among others. However, estuarine marine forms also are developed, ...
