it is now more than four decades from providing and execution of iran’s first comprehensive urban plan. evaluation of this plan shows that the process of execution has not been successful. considering the literature review, field study as well as comparing the plan’s documents, it is thought that lack of coordination between the urban planning organizations, the manner of providing and executio...

In regions affected by artisanal and small-scale gold mining (ASGM), the inhalation of mercury vapor and the ingestion of fish contaminated with this metal constitute the main sources of mercury contamination that affect human health. Nevertheless, according to the World Health Organization, another source of contamination is polluted water. Although mercury in freshwater is usually found in ve...

Identifying the factors that affect domestic water demand and consumption is very important in management of available regional water resources. In this study, relationships between water consumption and rural household activities are determined by comparing a snapshot of water consumption with rural household behavior of low, medium and high water consumers. In addition, the factors affecting ...

This paper describes a web-based environment for learning discrete simulation. The main goal of the paper is to foster the process of e-learning simulation by providing students and teachers with effective and comprehensive tools for creating, storing and executing discrete system simulation models. For these purposes the FONWEBGPSS application was developed and integrated into the e-learning s...

Land reclamation in coastal areas may have a significant effect on local ground water systems. Steady-state analytic solutions based on Dupuit and Ghyben-Herzberg assumptions are derived to evaluate this effect. Two situations are considered, both with ground water flow resulting from precipitation recharge: the coastal aquifer of an extensive landmass and an island. The results show that after...

The Danube is an international river passing partly through Serbia. The protection of the environment and sustainable use of water resources is a primary task that implies constant monitoring of the quality status and evaluation of ecochemical status of the water in the Danube basin. The investigation includes calculation of all-inclusive water quality by the Serbian water quality index (SWQI) ...

France is currently embarking upon a drastic reform of quantitative water resources management. This reform relies on two principles: the definition of an upper limit to water abstraction per water body and the decentralization of the responsibility for allocating water among users, in particular in the agricultural sector. This paper looks at possible institutional arrangements and incentive-b...

Many studies of ground water pollution in general and nitrate contamination in particular have often relied on a one-time investigation, tracking of individual wells, or aggregate summaries. Studies of changes in spatial distribution of contaminants over time are lacking. This paper presents a method to compare spatial distributions for possible changes over time. The large-scale spatial distri...

A rainwater harvesting system (RWHS) is an alternative water resource that collects and stores rainwater from rooftops. It helps smooth out variations in water supply and sustainable water resources management. In this study, we investigated the potential benefits from sharing RWHS with nearby neighbors in a community. We introduced different mean, variance, and correlation in water demand for ...

The objective of the study is to analyse the actual availability of water resources and its impact on human health deterioration. The following aspects were studied: (a) human activities and environmental deterioration; (b) statistics on the availability and demand of water resources; (c) urban and industry wastes as sources of water resources contamination; and (d) deleterious effect of contam...
