Physical risk assessment for urban water supply in a developing country: A case of Mega City Dhaka

Water supply access in many developing countries is yet to fulfill Millennium Development Goals. Many local governments are incapable of managing their water resources either due to funding constrains or lack of adequate work force. This often results into poor services with low quality, insufficien...

Many local governments are incapable of managing their water resources either due to funding constrains or lack of adequate work force.
