Coastal canals in Bangladesh

Coastal canals in Bangladesh: Coastal Bangladesh in the south is criss-crossed by many river tributaries and canals. The canals are recharged during high tides and becomes empty at low tides twice in a 24-hours cycle. Farmers use its water to irrigate their crop lands during high tides. Such situation happens during dry season (Oct-March). While in summer (rainy season) such canals overflow and flood the adjacent areas including people's courtyards and orchards.
