Future Projection
Based on the analysis in terms of hazard analysis, vulnerability
analysis and risk analysis in several sub-districts, it is necessary to
take action against the availability of water reserves.
This availability is influenced by future projections of several regions
such as land use in some sub-districts. Areas that have the potential
for economic development will certainly attract the interest of
community groups to eventually form a population and inhabit the area.
Increasing the number of this population will certainly cause the volume
of water in a region will be reduced because the use of water per person
per liter will increase.
In addition, rainfall and geological conditions of a region also
determine the amount of water reserves. The higher the rainfall in a
region then the ability of the region to make the water reserve
increases. However, it should be noted also the geological condition of
the area. If the geological condition in the area is low porosity then
the area will be more vulnerable to disaster because the structure of
the land in the area has a large gap so that the possibility of
landslide and groundwater flow (runoff) will also be greater so that the
availability of water will decrease.
