Evaluating spatio-temporal subsurface water storage dynamics in catchments using non-invasive high-resolution sensing technologies


Project Description

This project focuses on evaluating the combined use of non-invasive water storage sensing technologies (geophysical imaging and cosmic ray sensing) to improve modelling and forecasting of subsurface water storage dynamics for catchment water resources management.

Hydrological models provide crucial tools in predicting the responses and recovery to climatic extremes and land management stresses. While the development and implementation of many environmental and land use / management policies strongly depend on catchment scale, the uncertainties associated with model simulations can be up to orders of magnitude and beyond any impacts predicted.

Traditional point/plot-scale studies (e.g. soil/borehole sampling) are unable to capture spatial heterogeneity while large scale satellite remote sensing studies are too coarse. Recent developments in novel sensing of subsurface water storage dynamics at more relevant scales offer great potential to improve hydrological modelling and forecasting. These innovative sensor technologies include cosmic ray sensing (CRS, also known as COSMOS) and advanced use of geophysical imaging techniques. While CRS provides high temporal resolution data on water storage in the very shallow subsurface, geophysics enables high spatial resolution estimates and at larger depth. The project will explore in details the spatiotemporal correlation between the two techniques and how they can be integrated for enhanced parameterisation and verification of catchment hydrological models.

The research will be based in two contrasted catchments in Aberdeenshire, where hydrological and CRS monitoring is already in place. It will involve acquisition of complementary data where relevant, including geophysics, and training in application and processing of non-invasive sensing techniques and hydrological modelling. The project will be based at the Northern Rivers Institute, which undertakes fundamental research to help understand the hydrological functioning of catchments as well as being involved in applied work such as water resources management.
