Abstract Robust water service delivery systems require an understanding of resource dynamics as a basis for planning sustainable solutions Jakarta, the capital with challenging provision performance. A significant gap needed to be closed coverage 64.06% and non-revenue at 45.06%. However, there is no detailed information on Jakarta's supply demand, which essential understand resources situation...

The infiltration rate and therefore the principal function of a sand based vertical flow constructed wetland (VFCW) is influenced by the content of suspended solids (SS) and chemical oxygen demand (COD) of the waste water supply. In this study there were three operating conditions defined as “No Clogging”; “Partly Clogging” and “Clogging”. Investigations on 21 VFCWs approved analytical differen...

Tensions over water resources in upland areas of northern Thailand are often attributed to reductions in water supply caused by forest clearing. This article argues that the hydrological evidence for such reductions in supply is very weak and that, rather, the key hydrological issue in upland catchments is a significant increase in water demand, especially during the dry season. The arguments a...

Accurate forecasts of water demand are required for real-time control of water supply systems under normal and abnormal conditions. A methodology is presented for quantifying, diagnosing and reducing model structural and predictive errors for the development of short term water demand forecasting models. The methodology (re-)emphasises the importance of posterior predictive checks of modelling ...

given the strategic remarkable rank of pistachio in non-oil exports, inputs’ management in its production is so important. as the scarcest input in agricultural sector, water is considered to be among the most important inputs of pistachio production.water inadequate supply and limate conditions increase water demand in pistachio growing areas. it is necessary to determine the real value or pri...

Most water managers use a mixture of both supply-side and demand-side policies, seeking to capitalize on the relative advantages of each. However, supply augmentation undertaken to avoid overdrafts can reduce the effectiveness of demand management policies if the two strategies are not carefully integrated. Such a result can stem from a type of moral hazard phenomenon by which consumers, aware ...

A two stage linear programming approach is used to estimate the willingness to pay (WTP) of individual households or groups of households for changes in a combination of probabilistic water supply reliability and retail price of water. By modeling the costs (financial and ‘perceived’) of implementing long and short-term conservation measures and assuming rational (expected value cost minimizing...

The main goal of this work is to provide an analysis methodology for assessment of water scarcity problems based on supply and demand. To this end, we must first determine what can be considered as supply and demand in the water scarcity problem. Although some variables involved are physical, economical or demographical, in our approach social factors are also included. This leads us to objecti...
