Flash flood is a regular event for the inhabitants of the north-eastern region of Bangladesh which is commonly known as Haor (Wet land). It is situated at the foothills of Assam and Meghalaya regions and are highly vulnerable for flash flood due to steep gradients of the topography of the Assam and Meghalaya region. Cherrapunji of the Meghalaya region annually receives highest amount of rainfall in the world. In 2004 and 2010, a major portion of matured Boro crops of the haor region was washed away by a sudden flash flood causing huge loss for the farmers.
This year, Weather Research and Forecasting (WRF) model simulation of the area using real-time GFS data indicates heavy to very heavy rainfall over the northeastern region over the next few days. By using real-time GFS data available at 12 April 2016, WRF model simulation showed positive rainfall signature and therefore, the results were validated by a second simulation using 14 April 2016 data and shows simillar result.
At this point, it is wise to take necessary precautionary measures to avoid unnecessary life and property damage. Boro is the only crop that can be grown in this region due to the flooded condition of the region over 5/7 months a year. Therefore, it is wise to harvest matured boro rice as soon as possible to avoid unnecessary crop loss.
