VITAL (Viability Intake Tool for Aquatic Life) is a tool developed by HYDREOLE to estimate the environmental impact of hydropower developments, with a particular focus on downstream fish migration. Validated by the French Biodiversity Agency, the tool fully complies with the most advanced guidelines. It incorporates all site-specific parameters — such as hourly or daily hydrological data over at least 20 years, downstream migration attraction flow, dam configuration, intake attractiveness, screen and fish bypass efficiency, turbine survival rates, and other key factors — to estimate the impact of a hydropower scheme on fish populations. Simulations are performed separately for each fish group, including salmonids, cyprinids, clupeids, cottids, anguillids and others.

SIMSEN is a software package developed by the Swiss Federal Institute of Technology Lausanne (EPFL, Switzerland. The software package enables modelling, simulation and analysis of the power networks dynamic behavior, speed drives and hydraulic systems with arbitrary topology. The strength of the software leads to the possibility of including into the simulation: hydraulic circuits, electrical installations, rotating inertias, control/command systems, with a very high degree of complexity for each part, ensuring to take properly into account all dynamics interactions. HYDREOLE uses SIMSEN for hydraulic and electrical transients calculation, water Hammer, power network stability and turbine control parameters definition.

DAILYDRO is a software solution developed by HYDREOLE to calculate energy production and forecast power output over periods of up to 50 years, using daily, hourly or even 5-minute time steps. The software takes into account the stream's hydrological time series and all characteristics of the hydropower scheme: gross head variation, head losses based on turbine discharge, sanitary flow, downstream migration and fish pass flows, efficiency hills of each turbine types, energy selling tariffs, outage and maintenance simulations, and more. This enables DAILYDRO to verify or predict, on a day-by-day basis, the expected energy production of a hydropower plant, or analyse the past production to identify optimization targets.

ETHyC (Evaluation Tool of Hydroelectric Capacity) is a powerful GIS tool developped by HYDREOLE dedicated to sites identification and energy potential evaluation. It is designed for project developers, local communities or energy authorities to help the identification of the most suitable sites and quickly calculate the best scenario’s technical characteristics (nominal discharge, gross head between the selected intake and powerhouse sites, installed power, annual energy production) for a wide range of scheme's size, from kW to GW. It is an easy-to-use solution with a friendly user interface to quickly define the best site configuration by selecting on the map the intake and powerhouse location. The tool is based on existing topographical, meteorological and topological data.

Rhino is a versatile 3D modelling software. HYDREOLE uses Rhino 3D to design and model its hydropower schemes, including dams, water intakes, canals, penstocks, powerhouses, turbines, electrical equipment and fish passes. This enables the experts team to fully control the design process, optimize sizing and check the scheme's operation under all hydrological and operational conditions.

AutoCAD is one of the most widely used drafting tools. HYDREOLE uses it extensively to design hydropower schemes, including projects based on on-site dimensional surveys of existing schemes. It is of great help to optimize new equipment integration — such as turbines, gates, valves and electrical systems — and to adapt hydraulic structures for optimal design and performance.

TURBNPRO determines hydroturbine sizing and type selection based on actual site data entered by the User. Typical performance and dimensional data of the hydroturbine size/type selected are developed by the program including speed, runaway speed and cavitation characteristics. TURBNPRO includes extensive graphics showing turbine performance tin various formats as well as identification of major turbine components and dimensions. The HYDREOLE's experts use TURBNPRO to quickly assess a wide range of configurations for a given site and erify the compatibility of different turbine types and layouts within the existing civil structures.

HEC-RAS allows the user to perform 1D steady flow, 1D/2D unsteady flow computations, sediment transport/mobile bed computations, stormwater pipe network modeling, and water temperature/water quality modeling. HYDREOLE uses HEC-RAS to accurately assess how technical solutions may affect water levels and flow velocities in waterways and stream bed. The software is used to build realistic hydraulic models tailored to each project, simulate both current and future site conditions, and visualize results graphically in order to anticipate the impact of proposed developments on the environment and existing infrastructure. Combined with HYDREOLE’s expertise in hydraulics and hydropower, HEC-RAS helps deliver high-quality studies that meet the technical and environmental requirements of each project.

TURBeau is a tool for modelling hydraulic systems and assessing water supply infrastructure. Developed by the Swiss Federal Institute of Technology Lausanne (EPFL, Switzerland), TURBEAU (TURBinage des EAUx potables) helps HYDREOLE efficiently identify sites suitable for drinking water turbining by evaluating their energy potential and economic viability.

HYDREOLE installs and operates piezometric level sensors equipped with on-line data transmission. These sensors enable continuous water level monitoring to estimate the hydrology of rivers and streams without existing data.

HYDREOLE performs spot discharge measurements in water streams, canals and pipes using high accuracy equipment based on fluorimetry, conductivity measurements or current meters. These measurements help establish rating curves for piezometric sensors and quantify tributary inflows along selected sections of a watercourse.
