Eaucea

What Eaucea does

Eaucea is an independent French water resource engineering consultancy headquartered in Toulouse, founded in 2002 and registered as a SARL under SIREN 441 783 289. It provides specialized consulting and modeling services to public water basin organizations (EPTBs), water agencies, departmental and regional governments, agricultural and irrigation bodies, and hydropower operators including EDF and SHEM, with over 500 reference projects completed across metropolitan France. The firm addresses integrated water resource management challenges — drought and low-flow support, climate impact assessment, biological flow determination, agricultural withdrawal allocation, hydropower concession support, and water governance — anchored in French and EU regulatory frameworks (Water Framework Directive, SAGE, SDAGE, GEMAPI).

Its core technology comprises a proprietary suite of nine hydrological, hydraulic, and environmental modeling tools developed over two decades. E-tiage is an online operational decision-support platform for real-time low-flow management, deployed since 2015 on the Lot and subsequently on the Garonne, Charente, Ardèche, and Aude basins, co-developed with EDF and Météo France. CycleauPE is a semi-distributed rainfall-runoff model integrating climate, land use, hydrogeology, and withdrawals, used for climate change impact studies. Turb'eau models hydroelectric producible potential, Sturieau simulates estuarine turbidity and water quality, Morph'eau provides rainfall-runoff estimation using satellite data (NASA, NIPON, EURO), and Tourd'eau, Teaurrent, Eauzoneh, and Preaufiler round out the modeling stack across agricultural scheduling, torrential habitats, wetlands, and hydrological data valorization. A multidisciplinary team of roughly ten engineers covers hydrology, hydrobiology, hydrogeology, climatology, agronomy, and geography, and complements this IP with field metrology (ADCP, bathymetric sonar, aquatic drones), public policy advisory, and authorization-dossier support, including a 2019 spin-off (Ingé-eau) dedicated to hydroelectric engineering design.

Core offering

Eaucea is an independent water and environment engineering consultancy headquartered in Toulouse, France, delivering specialized hydrological studies, hydraulic modeling, agro-environment analyses, hydroelectric engineering, metrology and water governance support to public agencies and private operators across metropolitan France. Its offerings combine a multidisciplinary team (hydrology, hydrobiology, hydrogeology, climatology, agronomy, geography) with a proprietary suite of operational decision-support and simulation tools — including the E-tiage online platform, CycleauPE rainfall-runoff model, Turb'eau hydroelectric potential model, Sturieau estuarine simulator and Morph'eau regional estimator — developed internally for low-flow management, water resource planning, estuarine dynamics, climate impact assessment and regulatory compliance.

Product overview

Eaucea is a specialized water resource engineering consultancy offering both proprietary software tools and professional services. Its software portfolio comprises seven dedicated modeling tools: E-tiage (operational drought management platform), Cycleaupe (rainfall-runoff hydrological model), Tourd'eau (agricultural water scheduling), Turb'eau (hydroelectric potential assessment), Sturieau (estuarine quality simulation), Teaurrent (torrential habitat evaluation), Eauzone h (wetland hydraulic management), Morph'eau (regional hydrological estimation), and Preaufiler (hydrological data valorization). The company provides complementary professional services in hydrology, agro-environment studies, hydropower engineering, metrology, and water governance support.
