This paper reports on the demand for water-based leisure activity in Ireland based on data from a nationally representative telephone survey. Participation and trip demand are modelled using an augmented Poisson count model and consumer surplus welfare estimates are derived. The model is also used to investigate the level of social exclusion in water-based leisure activity. The demand for four ...

Accurate forecast of water demand is one of the main problems in developing management strategy for the optimal control of water supply system. In this paper, a hybrid model which combines empirical mode decomposition (EMD) and least square support vector machine (LSSVM) model is proposed to forecast water demand. This hybrid is formulated specifically to address in modelling water demand that ...

Shortage of water resources and increasing demand to consumption of this scarce resource, leads to somenoticeable limitations. On the other hand, population growth and consequently, increasing demand for water in aridand semi arid regions , needs production in exchange of little amount of water consumption. To approach thisobjective, an experiment in the complete randomized blocks carried out i...

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...

We estimate the price elasticity of water demand with household-level data, structurally modeling the piecewise-linear budget constraints imposed by increasing block pricing. We develop a mathematical expression for the unconditional price elasticity of demand under increasing block prices and compare conditional and unconditional elasticities analytically and empirically. We test the hypothesi...

Assessment of long-term impacts of projected changes in climate, population, and land use and land cover on regional water resource is critical to the sustainable development of the southeastern United States. The objective of this study was to fully budget annual water availability for water supply (precipitation ) evapotranspiration + groundwater supply + return flow) and demand from commerci...

Small water enterprises (SWEs) have lower capital expenditures than centralized systems, offering decentralized solutions for rural markets. This study evaluated SWEs in rural Rwanda, where nine health care facilities (HCF) owned and operated water kiosks supplying water from onsite water treatment systems (WTS). SWEs were monitored for 12 months. Spearman's Rank Correlation Coefficient (rs) wa...
