| Abstract | Challenging to make a prediction of future urban water demand is that of
nonlinear function of climatic and socioeconomic variables. Future changes of
those that relevant factors certainly influence future demand. Thus, forecasting
technique has to be reasonable come up from a significant and reliable way in
order to efficient plan and operate every water supply system. More importantly
the technique has to be able to investigate the amount sensitive of variables on
forecasting the demand. The objective of this research is to estimate the effect of
climatic and socio-economic changes of future water demand for Bangkok.
Therefore, this study divided into three parts: obtaining future climatic and socioeconomic,
correlation analysis and modeling future the demand.
As a result, downscaled HadCM3 provided the satisfying results representing the
present day precipitation, minimum temperature, evaporation and relative
humidity of the study area. On the other hand, corrected ECHAM4/PRECIS
represented better for representing daily maximum temperature. About
correlation analysis, numbers of connection is the most highly correlated with
existed water demand for yearly and monthly scales. Using Artificial Neural
Networks software, in long term demand model with coefficient correlation of
96.6%, results indicated that climatic variables have contributed to future
demand, but less than the contribution from numbers of connections. For medium
term demand model with coefficient correlation of 95.1%, models has combined
more climatic variables, and provided the best result suggesting that smaller
scaled demand models significantly influenced by climate. The results from this
research should help MWA in a way of verify making reliable and reasonable
decision for manage and construct their water supply improvement project to
cope with future water demand for Bangkok and its vicinities |
