Step 4: Setting Target for Basin Flood Management Plan

The overall objective of a flood management plan is to prevent flood hazards turning into disasters while maintaining the benefit of floods.

Systematic actions in the cycle of preparedness, response and recovery based on the flood risk assessment carried out would help determine the distinct targets. These targets should clearly articulate as to how the flood risks would be reduced or managed. The targets would vary within a basin according to the natural conditions, state of socio economic activities and resultant damages. For example, the target for rural areas in a hypothetical basin could be:

  • To reduce flood risks in rural agricultural areas by avoiding exposure to floods below 10 years frequency,
  • To deal with risks from all higher floods by reducing the exposure and vulnerability

Since most of the river basins around the world have certain flood control measures implemented, it is important that these are taken account through an analysis of their past performance and efficiency. This clearly facilitates the formulation of realistic and achievable targets.

Furthermore it is crucial to define the scope of the basin flood management plan in terms of the geographical area covered should. A river basin (e.g., Mekong River in South East Asia, Yellow river in China) may be too big to have one set of basin flood management goals. In such cases, based on the regional characteristics, and issues it may be appropriate to develop separate plans for each of the sub-basins. On the other hand, a number of small basins, falling within a given administrative jurisdiction could be treated as a single unit for developing such a plan.
