Jordan is characterized as a “water scarce” country. Therefore, conserving ecosystem services such as water regulation and soil retention is challenging. In Jordan, rainwater harvesting has been adapted to meet those challenges. However, the spatial composition and configuration features of a target landscape are rarely considered when selecting a rainwater-harvesting site. This study aimed to ...
Management of urban stormwater to mitigate Combined Sewer Overflows (CSOs) is a priority for many cities; yet, few truly innovative approaches have been proposed to address the problem. Recent advances in information technology are now, however, providing cost-effective opportunities to achieve better performance of conventional stormwater infrastructure through a Continuous Monitoring and Adap...
In this research, a method is proposed to identify and determine rainwater harvesting potential in a watershed based on geomorphological factors through integrating Geographical Information System (GIS) and Analytical Hierarchy Process (AHP). For this purpose, land use, land cover, topography, geology, soil, vegetation, and soil permeability factors were considered the as main geomorphological ...
Surface water resulted from rainfall-runoff responses in a basin is a potential water source that if it is managed properly can be useful to demand secure. In this study, hub coating algorithm (PR) and geographic information system (GIS) were used to identify areas with potential in Birjand plain for rainwater harvesting. The weight of 18 decision-making indices was calculated and prioritized u...
[1] Indian megacities face severe water supply problems owing to factors ranging from growing population to high municipal pipe leakage rates; no Indian city provides 24/7 water supply. Current approaches to addressing the problem have been “utility centric,” overlooking the significance of decentralized activities by consumers, groundwater extraction via private wells, and aquifer recharge by ...
Previous studies of the bacterial quality of roof-harvested rainwater have been confined to either detection of specific pathogens and faecal indicator organisms, or epidemiological studies of health effects associated with consumption of stored rainwater. As yet however, a general consensus on tank-water quality has not been reached. In this paper it is proposed that achieving reliable microbi...
Total water cycle management (TWCM) discussion mostly limits the role of residential rainwater harvesting to providing an alternate water supply to a fraction of fit-for-purpose end uses. However, with operational improvements, greater outcomes can be achieved. By increasing the portion of roof area connected and developing adaptive rainwater diversion (ARD), reliable stormwater management outc...
Adaptation measures are necessary for reducing the impacts of extreme climatic events, especially at the community scale. Constructed wetlands and rainwater harvesting systems are commonly used as on-site water supply systems for distributed adaptation. The purpose of this study is to build a community water supply model and to evaluate the performance of low impact development (LID) modules as...
To address concern regarding water sustainability, the Australian Federal Government and many state governments have implemented regulatory mechanisms and incentives to support households to purchase and install rainwater harvesting systems. This has led to an increase in rainwater harvesting in regional and urban Australia. This review examines the implementation of the regulatory mechanisms a...
Northeastern Mexico is a semiarid region with water scarcity and a strong pressure on water sources caused by the rapid increase of population and industrialization. In this region, rainwater harvesting alone is not enough to meet water supply demands due to the irregular distribution of rainfall in time and space. Thus, in this study the reliability of integrating rainwater harvesting with gre...
