IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

ABSTRACT
Kuwait is located at the upper part of the Arabian Gulf, and its marine environment has undergone extensive
environmental stress because of ongoing coastal development activities along its coastline. Mainly, oil related activities,
other developmental projects and anthropogenic activities have resulted in numerous marine pollution issues. One of the
main sources for such pollution in the marine environment is domestic-industrial sewage discharge from coastal outfalls.
High concentrations of nutrients in water bodies such as phosphate can lead to excessive algal blooms, fish kill incidents,
oxygen depletion and ultimately eutrophication phenomenon. Bottom marine sediments are considered the ultimate sink
for contaminants and their levels in sediment could sometimes reflect the general status of marine ecosystem health.
Sediment samples were collected from selected outfalls along Kuwait coastline from four main sampling zones (covering
the area from Kuwait Bay to the southern region of Kuwait¡¯s coastline). Loosely bound phosphate levels were determined
in sediment samples using spectrophotometer. The highest average phosphate concentration was measured at zone (A)
0.54 mg/g, followed by zone (B) 0.13 mg/g, then zone (C) 0.07 mg/g and finally zone (D) 0.05 mg/g. Variations of loosely
sorbed phosphate concentrations noticed in the investigated sampled zones clearly indicate the nature of anthropogenic
activities associated with each sampling zone. Findings from this study are significant for environmental impact
assessment of Kuwait marine ecosystem health and for the understanding of water and sediment quality patterns in the
region.
