The Asian Tsunami and Post-Disaster Aidunoff is accelerated by drainage systems of gulleys, pipes and sewers. Obviously the time to peak of a hydrograph and the percentage runoff will be decreased and increased respectively compared with a natural catchment of permeable soils and vegetation.

When the losses arising in these ways are all provided for, there may remain a surplus that, obeying the gravitation laws, flows over the surface to the nearest stream channel. The streams coalesce into rivers and the rivers find their way down to the sea. When

The Asian Tsunami and Post-Disaster Aidimilarly in chapter 9, the equation for ., the mean annual maximum flood for Region 6, departs from the general equation and includes an URBAN term. URBAN, it may be recalled, is the fraction of catchment in urban development. The reason for this special term’s inclusion is the need to take account
