Aquatic environment studies

General objectives

Training in techniques and methods for the study and management (impact assessment, preservation, maintenance, management, etc.) of aquatic environments (wetlands, watercourses). 

This presupposes knowledge of the specific regulations governing the management of terrestrial wetlands, of the hydrological and hydraulic functioning of these environments, of the methods used to observe, monitor and characterize these environments, and of the associated taxonomic groups (including river fish). And to apply some of this knowledge to concrete case studies, in order to understand the complexity of these natural environments, sometimes anthropized, through complementary disciplinary fields.

            Sequence 1: Regulations and hydrological functioning of wetlands

            Sequence 2: Understanding flows, impacts of development and tools for characterizing watercourses

Sequence 3: Fish taxonomy, principle of electrofishing and assessment of wetland condition indicators

Sequence 1: Regulationshydrological functioning of wetlands

Non-classroom-based: to be carried out individually

Research into players, issues, European and French regulations.

Or Research to be carried out on the various wetlands.

Face-to-face, in the form of TD: 5h

Pooling of regulatory research and matrix analysis of regulatory texts.

Pooling research on wetlands: Identification of different wetlands (with publication of an image database) and their associated catchment areas (with mapping application).

Understanding the hydrological functioning of wetlands and watersheds.

Sequence 2: Understanding flows, impacts of development and tools for characterizing watercourses

Face-to-face, in the form of TD: 5h

Principles of hydrometry (measurement of heights, velocities) and tools for characterizing wetlands via direct measurements (physical, chemical and hydrodynamic parameters), observations (morphological, sedimentological), raw data analysis (Q(H), QMNA, minimum biological flow, classified flows, QT...).

Introduction to free-surface hydraulics in permanent flow and in the vicinity of structures through small case studies (recalibration, weir or pass).

Face-to-face, in the form of a Field trip 5h

To be carried out collectively: Observations of the impact of structures and hydraulic processes in situ. Hydraulic measurements on the weir and hydraulic jump (nearest site the Lez). In-stream chemical measurements (on-site and SEQ-eau).

Non-classroom-based: To be carried out in pairs: Creation of pedagogical and technical description sheets based on site visits and bibliography.

Sequence 3: Fish taxonomy, principle of electrofishing and assessment of wetland condition indicators

In-class TD by an external lecturer: 5h

Taxonomy of French freshwater fish and the principle of electrofishing

Method for evaluating indicators of their condition (IBGN, I2M2)

- Identify, select and apply a combination of analytical tools (current techniques, instrumentation) adapted to characterize organisms (from the biomolecule to the individual in all its complexity) and their functioning at different levels of analysis (intracellular metabolism, biology and physiology of org

- Identify sources of error to calculate the uncertainty of an experimental result.

- Work as part of a team as well as independently and responsibly on a project.

- Step back from a situation, assess yourself and challenge yourself to learn

- Analyze and synthesize data for further processing.
