E n g i n e e r i n g G e o l o g y Table 8.2. Generalized flood hazard zones and management strategies (after Kenny, 1990). With the kind permission of the Geological Society Flood hazard zone I (active floodplain area) Prohibit development (business and residential) within floodplain. Maintain area in a natural state as an open area or for recreational uses only Flood hazard zone II (Alluvial fans and plains with channels less than a metre deep, bifurcating and intricately interconnected systems subject to inundation from overbank flooding) Flood proofing to reduce or prevent loss to structures is highly recommended. Residential development densities should be relatively low; development in obvious drainage channels should be prohibited. Dry stream channels should be maintained in a natural state and/or the density of native vegetation should be increased to facilitate superior water drainage retention and infiltration capabilities. Installation of upstream stormwater retention basins to reduce peak water discharges. Construction should be at the highest local elevation site where possible Flood hazard zone III (Dissected upland and lowland slopes; drainage channels where both erosional and depositional processes are operative along gradients generally less than 5%) Similar to flood hazard zone II Roadways that traverse channels should be reinforced to withstand the erosive power of a channelled stream flow. Flood hazard zone IV (Steep gradient drainages consisting of incised channels adjacent to outcrops and mountain fronts characterized by relatively coarse bedload material) Bridges, roads and culverts should be designed to allow unrestricted flow of boulders and debris up to a metre or more in diameter. Abandon roadways that presently occupy the wash flood plains. Restrict residential dwelling to relatively level building sites. Provisions for subsurface and surface drainage on residential sites should be required. Stormwater retention basins in relatively confined upstream channels to mitigate against high peak discharges. Emergency action involves erection of temporary flood defences and possible evacuation. A flood warning system can be used to alert a community to the danger of flooding. The success of such measures depends on the ability to predict floods and the effectiveness of the warning system. However, widespread use of flood warning is usually only available in highly sensitive areas. Warning systems often work well in large catchment areas that allow enough time between the rainfall or snowmelt event and the resultant flood peak to allow evacuation and any other measures to be put into effect. By contrast, in small tributary areas, especially those with steep slopes or appreciable urban development, the lag-time may be so short that, although prompt action may save lives, it is seldom possible to remove or protect property. No structure of any importance, either in or adjacent to a river, should ever be built without giving due consideration to the damage it may cause by its influence on flood waters or the damage to which it may be subjected by those same waters. The maximum flood that any such structure can safely pass is called the design flood. If a flood of a given magnitude 404
