3.0 Conducting a Vulnerability Assessment3.4.2 Low-technology methodsIf sophisticated high-technology survey techniques arenot available or affordable, a low-technology approachcan provide elevation information with acceptableaccuracy, if done carefully.Although high-technology methods such as dGPS arepreferable, topographic elevation can be quantitativelydescribed with respect to tidal range using a lowtechnologywater level method (Figure 26). Thefundamental principle of this technique is that waterlevel is level during the latter half of rising tides. Hencethe corresponding depth beneath water level can helpto calculate the relative elevation of the mangrovemud surface. A rising tide is best for this approach asit has been shown that water surfaces on the flood tideare horizontal and, while on the ebb, tend to declineslightly seawards (Healey et al., 1981).Figure 26 shows a mangrove forest in profile, withspecies A (i.e. Avicennia) at the seaward zone, R(i.e. Rhizophora) just inside this and B toward thelandward edge (which in Tanzania and Fiji wasBruguiera, and in Cameroon was Laguncularia).Arrows show the sample design for a water levelelevation survey.In Figure 26, h is the reference station and d1, d2, d3,d4, etc. are different locations within the mangroves atwhich to measure mud surface elevation. Most criticalfor purposes of the VA are zone transitions.How to collect dataEquipment RequiredReference station (h)– Survey stake graduated in mm with 0 at the base– Clear plastic tube cut from a drink bottle to go overthe stake– Accurate source of time, such as mobile phone– Communication with rover (preferable but notnecessary)– Pencils and copies of data sheets (in Appendix)– Personal safety gearRover (d)– Stiff measure graduated in mm (roll-up builders’metal tapes are good)– Accurate source of time, such as mobile phone– Communication with reference station (preferablebut not necessary)– Pencils and copies of data sheets (in Appendix)– Personal safety gearBy Michael HelmanFigure 26.
