This paper presents a non-linear optimal control strategy for the operational management of water distribution networks (WDNs) including both flow and hydraulic head/pressure constraints. The optimal operation of WDNs should guarantee water supply with suitable pressures at all the demand nodes in the network. The challenge for non-linear model predictive control in this context is to compute c...

While many water management tools exist, these systems are not usually interconnected and therefore cannot communicate between one another, preventing Integrated Water Resources Management to be fully achieved. This paper presents the solution proposed by WatERP project * where a novel solution enables better matching between water supply and demand from holistic perspective. Subsystems that co...

This paper is part of a broader project that provides a microfoundation to the General Theory of J. M. Keynes. I call this project “old Keynesian economics” to distinguish it from new-Keynesian economics, a theory that is based on the idea that to make sense of Keynes we must assume that prices are sticky. I describe a multi-good model in which I interpret the definitions of aggregate demand an...

Gene-Culture Coevolution (GCC) theory is an intriguing new entry in the quest to understand human culture. Nonetheless, it has received relatively little philosophical attention. One notable exception is Kim Sterelny’s (2006) critique which raises three primary objections against the GCC account. Most importantly, he argues that GCC theory, as it stands, is unable to resolve “the paradox of cul...

Currently, water demand management and optimal operation of its resources is one ofthe most important issues in environmental economics and management. Water demandmanagement has been a concern of economic planners as a new approach in environmentaleconomics. This study aims to investigate water demand management in different productmarkets in downstream of Yengejeh Dam in Neyshabur. This is an...

A new indicator of drought-induced water stress is introduced and applied at the county level in the USA. Unlike most existing drought metrics, we directly consider current daily water demands and renewable daily water supply to estimate the potential stress. Water stress indices developed include the Normalized Deficit Cumulated to represent multiyear droughts by computing the maximum cumulati...

Asia and Middle East represent one of the most dynamic regions in the world which has experienced fast economic and technological growth. Access to clean and affordable water is essential for building resilience and maintaining human’s well-being and livelihood development in this region. Likewise, various energy resources are fundamental to support stable economic and social progress for bette...

abstract in the recent decades, the iranian economy has been highly depended on oil revenues. considering the fact that a great part of non-oil exports are agricultures product, studying factors influencing growth of agricultural sector plays an important role in the iran's economy. supply domestic shocks and domestic demand pressure along with deviation of exchange rates from its equilibrium, ...

Restrictions on the use of water supplied by water corporations are frequently introduced in Australian cities whenever the demand for water exceeds the experienced or anticipated supply. This paper examines evidence from a stratified random survey of 2179 households in Sydney in a period when restrictions on domestic water use outside the home had just been imposed. The paper explores attitude...
