when surface runoff is considered as local water sources, the other types of local sources are<br />
automatically taken into account.<br />

there are more possibilities of combination. However, if such complicated options are considered, it<br />
means that the water is very scarce, whereby only these three extreme options are involved.<br />
Explanation: as the exemplar, the table is blank. During the calculation, two tables are generated for<br />
system cost and energy consumption each.<br />
