Titre : Use of phase-sensitive radar to monitor discharge and recharge of Moroccan aquifers

Pays : Maroc

Numéro du projet : GB-GOV-13-FUND—GCRF-NE_R009589_1

Organismes de mise en œuvre : NERC British Antarctic Survey

Durée : Actual Start 01 Nov 2017 // Actual End31 Dec 2018

Objectifs
The objectives of the proposed project are fourfold. 1. Determine through field trials the envelope of capability of the ApRES instrument at different radar frequencies in arid regions. The rate of absorption of radio waves in typical soils depends strongly on the radio wave frequency : lower frequencies are more appropriate for the detection and monitoring of deeper water tables (> 100 m). There are, however, other disadvantages to using lower frequencies. 2. Contribute to a parallel, fully resourced study that seeks to understand how the ability to monitor aquifer levels can be applied in the most transformative way. As a separate investigation, a Development i-Teams study will be determining the optimal approach to securing the best outcomes downstream of the project, specifically assessing how a monitoring network could be integrated into the diverse approaches to groundwater management adopted by different nations. 3. Assess the potential to make the instrument cheaper to manufacture and robust to the environment. The ApRES instrument is well-suited to the cold, dry conditions of Antarctica, but will need to be hardened against higher temperatures and wetter conditions. The design was not optimised for economy, and various manufacturing approaches need to be investigated to determine the cheapest and simplest, while maintaining reliability. 4. Work out how to deskill the interpretation of the ApRES datasets. At present, the ApRES dataset needs to be interpreted by an expert. Possibly the most challenging part of the project will be to develop data-processing algorithms that can be applied by trained, but otherwise relatively unskilled operators.
