Water Storage Variations Over Bangladesh

Abstract

Climate change can significantly influence terrestrial water changes around the world particularly in places that have been proven to be more vulnerable such as Bangladesh. In the past few decades, climate impacts, together with those of excessive human water use have changed the country’s water availability structure. In this study, we use multi-mission remotely sensed measurements along with a hydrological model to separately analyze groundwater and soil moisture variations for the period 2003–2013, and their interactions with rainfall in Bangladesh.

In the absence of any considerable decrease in precipitation over the region, a remarkable groundwater reduction is observed from the first and second Intrinsic Mode Functions (IMFs), which can be referred to human impacts. High spatio-temporal resolution remote sensing products along with the data assimilation methodology show a high capability for studying water storages in Bangladesh.
