“Towards a culture of preparedness for better flood management”

Vol. 7 No. 2 August 2014

From the Co-Editor’s Desk In India, in general and in Bihar in particular, water engineers and water managers are always on tenterhooks during

the monsoon period. We sit with our hands crossed praying for an optimum rainfall, no more no less. While excessive rain brings flood, the shortage of it causes drought.

Besides skewed rainfall, we are also exposed to frequently occurring natural calamities like the one which happened in Nepal when an artificial ‘dam’ was created due to massive landslide across the river Sun Kosi. FMISC has played its part in keeping round- the- clock vigil over the possible fall-out of this natural event in Bihar. We were hopeful that with the Indo-Nepal efforts, the huge amount of water collected behind the artificial landslide mass will be safely carried to the outfall.

Flood News

Nullifying the effect of El Nino, there was very good rain in the second and third week of August both in Bihar and Nepal. This resulted in averting the drought like situation, but at the same time brought floods in some rivers of Bihar causing damages to some embankments as given below:-

• Damage in Kamla Balan right embankment causing floods in villages of Ghanshyampur Block under Darbhanga district.

• Damage in Bagmati left embankment causing floods in villages in Suppi Block under Sitamarhi district.

• Many villages in West Champaran district were also flooded due to damage reported in Champaran embankment on river Gandak, and in Gopalganj district due to damage in Sallehpur Tandaspur Chharki.

• Nalanda district also faced severe flood because of breach in some Zamindari Bandhs and overbank spilling of local rivers. Due to heavy rain and drainage congestion, there was

severe waterlogging in several parts of Patna which continued for days together. Drainage system in Patna definitely needs to be improved.
