It was also assumed that urban areas would have an influence proportional to their size since larger urban areas would logically have more employment opportunities. The urban pull factor map thus shows the degree of pull of the nearest urban area at each location. Land Suitability Fig. Not all lands are equally suitable for urban development. Slope Gradient Fig.
Steeper slopes cost more to construct upon.
Consequently, the lower the slope, the more suitable for settlement. Likelihood of Flooding associated with Typhoons Fig. As indicated earlier, this area is highly susceptible to storm surges associated with typhoons. Using the frequency data available and the projected level of the sea in 2100, the probability of being flooded from a typhoon storm surge was evaluated using a similar procedure to that used to predict the new sea level. Clearly areas covered by the new level of the sea could not be considered in the solution.
