Water storage Events

Alongside the effects of climate change and anthropogenic factors, natural climate cycles have considerable impacts on the hydrologic cycle. In this study, we look at how global climatic oscillations cycles, like El Niño–Southern Oscillation (ENSO) and the Indian Ocean Dipole (IOD) affect total water storage and groundwater storage in the Orange-Senqu River Basin by analysing two large aquifers: the Stampriet Transboundary Aquifer System (STAS) shared between Botswana, Namibia and South Africa, and the Karoo Sedimentary Aquifer shared between Lesotho and South Africa.

Presentation 1: Analyses of Groundwater Storage Change in the Usutu-Mhlatuze Drainage Region using GRACE Satellite Data TALK ABSTRACT: The Gravity Recovery and Climate Experiment (GRACE) satellite data interpretation provides an integrated measure of monthly terrestrial water mass changes. The GRACE satellite data has been successfully used to estimate the monthly changes of terrestrial water storage (TWS) including groundwater storage changes. This presentation will provide an overview and application of the GRACE satellite product to
