Technical Modelling

Environmental Modelling in Qatar

GSustain delivers technical environmental modelling services for projects across Qatar and the GCC. Our modelling capabilities support environmental impact assessments, regulatory permitting, operational compliance, and engineering design — providing the quantitative evidence that regulators, operators, and stakeholders require for confident decision-making.

We understand what Qatar regulators expect from modelling submissions.

Technical Credibility

AERMOD, CALPUFF, and noise modelling delivered by qualified environmental scientists.

Efficient Delivery

Modelling studies typically completed within 3-6 weeks depending on complexity.

Common Questions

Frequently Asked Questions

What is air dispersion modelling?

Air dispersion modelling uses mathematical models (such as AERMOD) to predict how pollutants emitted from sources (stacks, vents, fugitive sources) disperse in the atmosphere. The results show predicted ground-level concentrations at receptor locations — used to assess compliance with air quality standards.

When is environmental modelling required?

Environmental modelling is typically required as part of an EIA for industrial projects, or when regulators need quantitative evidence of compliance with air quality, noise, or discharge standards. Qatar Energy requires modelling for projects in Ras Laffan and Mesaieed.

Which air quality models does GSustain use?

We primarily use AERMOD (the US EPA preferred regulatory model), supported by CALPUFF for complex terrain and long-range transport, and ISC3 where specified by project requirements.

Can GSustain integrate modelling with EIA delivery?

Yes. Our modelling team works within our EIA practice, allowing seamless integration of modelling outputs into environmental assessment reports without the delays and coordination overhead of subcontracting.
