Rainfall‐induced ground deformation in southern Africa

نویسندگان

چکیده

We present an analysis of ground deformation induced by large-scale seasonal rainfall in Southern Africa, based on GPS and GRACE time series simulations elastic flexural response to hydrological loading. This study including South Zambia, Angola, North Namibia Botswana displays a latitudinal precipitation gradient between tropical semi-arid conditions. data display annual variations water mass decreasing drastically southwards. three permanent stations located show synchronous vertical displacements with amplitude southwards from 4 2 cm, shift 2–3 months the main season. Flexure integrating rainfall, evapotranspiration, storage, flood migration river output produce flexure up 6 cm timing agreement series. It highlights buffering surface aquifer Kalahari sands.

Ground Deformation Mapping Using Insar

SAR interferometric data can be used for extracting three dimensional information of the earth’s surface by using the phase part of the radar signal. In this study, available SAR interferometric data acquired before and after the Marmara earthquake of 1999 and provided by ESA were used for mapping the ground deformation in the satellite line of sight (LOS) in the Izmit province. The interferome...
