Public restitution seminar on Hydroacoustic SPM measurement technology for operational use - Project M.ES.U.R.E.

You are cordially invited to the restitution seminar of the ANR Asma project entitled M.ES.U.R.E. - Métrologie mES hydroacoUstique opéRationnElle- (2017-2020), to be held:

on Tuesday, March 10th 2020 at Laboratoire LEGI
from 9:00 to 17:00 1209-1211 rue de la Piscine
Domaine universitaire
in the K118 room 38400 Saint-Martin d'Hères.

This seminar is meant to present the outcomes of this 3-year project on Suspended Sediment Transport Measurement.

If you wish to attend this event, please reply to this free (but mandatory, before February 24th 2020) registration link by specifying your name and affiliation in parenthesis after your name.

Among the technological challenges of operational flow monitoring, Suspended Particle Mater (SPM) measurements are of primary importance nowadays because they address several fundamental environmental, industrial and society issues related to the prediction of extreme climatic flow events and their impact on fluvial, estuarine and coastal flow morphodynamics; the management of hydro-electrical resources; the integrated coastline management strategy; the monitoring of wastewater networks; the sustainable use of natural water and sediment resources; the design of environmental hydraulic structures; the fishery resources management.

However, SPM measurement science which aims quantitative estimations of SPM concentration, sizes and fluxes in aquatic hydrosystems, remains at a very low Technological Readiness Level (TRL 3) in spite of the significant progress made over the past two decades in operational monitoring of flow current, discharge and bathymetry (TRL>6). This situation arises from the inherent complexity of ultrasound scattering theory, requiring advanced scientific knowledge and methodological expertise still not readily accessible to the industrial sector. As a result, a profound technological gap exists in SPM measurement science between the academic and industrial sectors.

The present MESURE project has the objective to reduce this gap via the transfer of recent skills and know-how in hydroacoustic measurement science acquired by the academic partners of the project toward the industrial partners. To reach these objectives, two advanced measurement tools are developed:

  • an open-source software tool named HYDRAC dedicated to hydroacoustic inversions for a large variety of SPM conditions in oceanic and river flows;
  • an industrial instrumentation prototype UB-MES of the ACVP measurement technology of LEGI developed by the SME partner UBERTONE.

The originality of the envisioned tools lies in their high technological readiness level (TRL 5) which facilitates the emergence of a performant SPM technology for operational use and the potential marketing of a novel instrumentation by the SME partner.
