Finding Potential Sites for Small-Scale Hydro Power in Uganda: a ...

A more advanced way of presenting the result would be to take more factors of interestinto account. Such factors could be population density and distances between roads andpotential sites, which can be seen in Figure 5.10.Figure 5.10 Overview map showing distribution of potential sites per sub-county. The segments inthe pie chart diagrams represent the proportion of sites within a certain distance from a road. Thesizes of the pie chart represent the number of potential sites in the sub-county. The colors of thesub-counties symbolize the variation of population density.This figure helps to decide which areas that have a high population density as well ashigh number of potential sites and their distances to roads. As in Figure 5.9 above, thedegree of detail is rather generalized; therefore if the exact position is desired, a moredetailed map over a smaller area can be used (see Figure 5.11).Figure 5.11 Geographic position of potential sites in Ikumba sub-county. Each red line, regardlessof its length, indicates one potential site for a small-scale hydropower station.53
