PROJECT/CLIENT ISSUES SOLUTIONS
Maintenance of navigational channels and preser-
vation of water quality in the face of rapid develop-
ment.
How to assess the environmental impacts of exist-
ing and future developments along coastline.
How to assess the environmental impacts of exist-
ing and future developments along coastline.
Dubai Creek is prone to eutrophication from nutri-
ent discharges. Development could exacerbate
existing problems or create new areas of concern.
Major NYC Development Project would impact
sewer discharges and stormwater/CSO discharges.
Evaluate existing sewer system capacity and cur-
rent water quality conditions in affected surface
water.
Spill modeling and crisis management tools have
been applied to Gulf waters for over 10 years. The
models allow emergency managers and planners to
respond to oil and chemical spills as well as search
and rescue cases.
Expansion of exploration & production facilities
required environmental studies to define risk.
Determine mixing zone, evaluate potential thermal
impacts to biological resources and develop mitiga-
tion concepts that minimize impact from increased
discharge of heated water.
Assess the dilution of treated sewage discharge
from a proposed upgrade to a sewage treatment
plant and extension of existing marine outfall.

Water Quality Modeling/Assessments
HydroQualASA develops water quality model computer codes, but more importantly, our
personnel are world renowned for application of these models to solve complex
water quality probelms. Our experts have worked on water quality problems in the
world’s largest cities impacted by their coastal environment. Models have been
developed to address the following:
w Coastal Hydrodynamic/ w Toxic Substance Fate and Transport
Circulation Analyses w Food Chain and Bioaccumulation
w Coastal Eutrophication w Water Sediment Criteria Development
w Pathogens and Beach Protection

Dispersion Modeling
Analyzing and solving difficult environmental problems connected with coastal, estuary and waterbody environments is the focus of
HydroQualASA's services to its clients. With over 25 years of environmental engineering experience, we are specialists in measuring
and evaluating impacts associated with the development and management of these environments and their surroundings. We provide
clients with solutions to improve water quality, manage the impacts from development, mitigate oil and chemical spills, and evaluate
the effectiveness of remediation alternatives. To accomplish this, HydroQualASA conducts field studies and applies advanced com-
puter tools to analyze the physical, chemical and biological processes that assist in the development of practical solutions. These com-
puter tools include models for oil spills, chemical spills, sediment transport, water quality, atmospheric releases and search & rescue.
The joint venture between HydroQual and ASA merges two organizations with world class scientists and engineers with expertise in
environmental services for the Arabian Gulf.
