The characteristics of Bangladesh and the possible causes of flooding.

Extracts from this document...

Introduction

The characteristics of Bangladesh and the possible causes of flooding. Bangladesh is situated between 22� and 27� North, either side of the tropic of cancer. It is bordered by India to the West, North and East, and by Myanmar to the South East. It is South of the Himalayas and North of the Bay of Bengal. Bangladesh Is very flat (all less than 200m ASL [above sea level], with 15% of land being less than 15m ASL. There are two main rivers in Bangladesh, The River Ganges and The River Brahmaputra. There are 230 river and tributaries in Bangladesh in total, which all drain southwards. ...read more.

Middle

The silt in the delta was eroded by the surface runoff picking up soil from fields, and by abrasion of the riverbed. It is transported by the sea waves, and by longshore drift. The flooding in Bangladesh is due mainly to the low-lying, flat ground, which makes the water spread out easily. The drainage density is high, so there is lots of water to create a flood, and coastal cyclones can sweep across the low-lying coast. The river discharge is often low between January and July, and then increases rapidly between June and August (to a peak of 45000 cumecs), and dropping from September to November. ...read more.

Conclusion

This is helpful because it reduces the flood risk towards the houses situated on the land below. Without these trees, the water run-off has no interception and will flow towards the lowland and lead to increased drainage, which leads to flooding. The rainfall in India and Nepal is very important to Bangladesh, as it flows down into Bangladesh and could destroy their crops. It also provides fresh water for drinking. This is proved when we look at the total annual rainfall for all three countries. At 2000mm (500mm less than Northern India and 1000mm less than Nepal), we can see that the main problem springs from the water flowing down from the surrounding countries. ...read more.
