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.
