Water-related disasters account for 70 % of total deaths due to disasters. Globally about 1.7 billion people are currently living in river basins¹. River flooding is one of the most common causes of economical losses. From the paper of Nature climate change, depending on the socio-economic scenario, it is found that human losses from flooding could rise by 70–83%, direct flood damage by 160–240% when 1.5-degree celsius increase in temperature globally². 

The above image shows the flooding in Gandaki river near the paniyahwa bridge, eastern Uttar Pradesh. The river Gandak flows southeast 300 kilometres (190 mi) across the Gangetic plain of Bihar state through West Champaran and joins the Ganga basin near Patna. In India Gandak’s total drainage area is about 7,620 square kilometres. Owing to a week of heavy rainfall Gandaki flooded from August 04, 2017. On August,09,2017, Sentinel 1A passed over the eastern Uttar Pradesh. Instruments such as Interferometric Wide (IW) swath mode in Sentinel 1A are being used to assess the area of damages. The damages can be categorized such as loss in urban areas, cropland, and further into specific crop type damages. These subcategories help us to assess the economic losses more precisely 

Assessment of historical flooding is essential for the development of regions which are close to the flood risk zones to minimize the economical loss in those areas. Satyukt Analytics is capable of assessing historical flooding globally. As microwave images have an advantage over the conventional optical images, Satyukt is able to assess the flood damage more accurately.
