Rhama Consultoria Ambiental Ltda

What Rhama Consultoria Ambiental Ltda does

Rhama Consultoria Ambiental Ltda, operating under the brand Rhama Analysis, is a privately-held Brazilian environmental engineering consultancy founded in 2004 and headquartered in Porto Alegre, Rio Grande do Sul. The firm delivers integrated solutions across three technical disciplines — hydrology, meteorology, and geotechnics — addressing dam safety, urban and riverine flooding, water quality, and climate-change impact assessment for infrastructure projects. Its service portfolio includes dam break rupture studies, hydrometeorological forecasting systems, water quality studies, flood risk analysis, hydrometeorological data consistency validation, integrated urban water management (GIAU), and master drainage plans for municipalities. The technical foundation rests on proprietary methodologies such as the MGB rainfall-runoff model (10km grid discretization), PMP/QMP estimation with climate change projections, and non-stationary Gumbel flood frequency analysis, developed and refined through a long-standing academic partnership with IPH/UFRGS.

The business model is project-based professional services, with revenue generated through public tenders, direct contracting, and consortium work for government agencies, water utilities, hydroelectric operators, and mining companies. The firm does not publish pricing and operates with customized, quote-based commercial proposals. Distribution is direct enterprise field sales, with thought-leadership marketing via a technical blog (successor to the legacy "BLOG DO TUCCI"), LinkedIn, YouTube, and Instagram, plus selective training engagements for regulatory bodies. The senior leadership comprises Carlos E. M. Tucci (Director of Hydrology) and Maria Assunção Dias (Director of Meteorology), whose academic credentials — including Tucci's coordination of the São Francisco river basin ANEEL study with IPH/UFRGS, INPE/CPETEC, and IAG/USP, and Dias's participation in the FAPESP-funded LBA Amazonia research (1998–2010) — anchor the firm's reputation. Recent strategic activity has been concentrated on deepening the IPH/UFRGS partnership (2024 hydrological bulletins), joining the Concremat consortium for the Gravataí master drainage plan (2025), and expanding into regulatory training (ARSESP, 2023) and mining-impact watershed monitoring (SENAI/FIEMG, 2024).
