Guarantee rate of freshwater in a river mouth intruded by saltwater with respect to the joint impact of runoff and tide
Saltwater intrusion is detrimental to water utilization. It is of vital significance to study the joint impact of runoff and tide on salinity and the risk of saltwater intrusion. To analyze the risk of saltwater intrusion, this paper proposes two concepts: critical runoff–tide level line and guarantee rate of freshwater. Taking Nandu River Estuary in China as a study case, a three-dimensional ...

Pb isotopes in drinking water: a new strategy for source detection of low Pb sources
Source detection of low concentrations of Pb in water, for instance less than 15 μg L-1, may require a new methodology as the tolerances of Pb in drinking water are further reduced. It appears that the isotope properties of Pb may aid discrimination among natural sources and anthropogenic sources, including some plumbing materials. Characteristic Pb isotope signatures in a typical rural water ...

CL#7 - In Situ BioLogix Application - Case Study
Site Information Dry cleaning solvents were found in the ground water at the former location of a dry cleaning facility at a commercial shopping center. Most of the mass of ground water contamination was located under a bank that was built over the former dry cleaners, restricting access for remediation. The PCE plume was estimated to be 30,000 square feet. The PCE concentration was greater than ...

Installation Examples: Battery Charging Turbines- Salamanca (Spain) - Case Study
The water network of Salamanca has a pressure regulation valve to supply a neighborhood of the city, reducing the pressure from 5,2 to 3bar. Near the pressure reducing valve (PRV) there are different public facilities, specifically an ornamental water fountain located in a garden square. Like in any PRV it is an energy potential traditionally never ...

Robust sensor placement for leak location: analysis and design
In this paper, a nominal sensor placement methodology for leak location in water distribution networks is presented. To reduce the size and the complexity of the optimization problem a clustering technique is combined with the nominal sensor placement methodology. Some of the pressure sensor placement methods for leak detection and location in water distribution networks are based on the ...

Pellissippi Parkway Study
Summary: At the Pellissippi site the investigation concerned finding hidden voids underneath the highway. It is built on a location where numerous cave-ins have occurred over the years. The objective at this site was to determine if it was possible to find new voids in the subsurface which could be expected to cause more cave-ins. At this site the Dip-Dip method was used with a 56 ...

Water security and sustainability in urban India
The rapid growth of population combined with rising levels of consumption and pollution has increased water insecurity in urban India. The depleting water sources on the one hand, higher financial and technological costs to refine and transport water from far off sources on the other, leave limited possibilities to augment the water supply in the near future. Climate change may further adversely ...

Four free surface algorithms for the 3D Navier–Stokes equations
Four algorithms are described for computing a steady free water surface with the solution of the three-dimensional (3D) Navier–Stokes equations. The numerical methods are used in hydraulic engineering cases, typically spillways and river modelling. The algorithms were tested against a laboratory experiment of a v-shaped broad-crested weir. The complex geometry of the weir introduced ...

Spatial interactions between organizations and the symbolic landscapes created by their public information campaigns
This study investigates public information as a component of the democratic process, advancing previous frameworks by considering information as a spatial product of multiple governmental and civil society organizations. The symbolic weight of information campaigns is a critical component of two democratic processes: awareness of the public's vulnerability to formal water policy change ...

Ground-breaking innovation in rainwater harvesting
Rainwater harvesting has for centuries been performed using simple methods. At the start of the 1990s, the first companies began launching standardised components on the German market. In 1997, at the leading international trade fair for sanitary, heating and climate control technology, the ISH, INTEWA was one of the first companies to present a complete station for rainwater harvesting. The ...

The need for Virtual Water Credits and Trading System
Understanding, sensitizing and accounting Virtual Water Trade (the embedded water flow) between locations, nations and geographies is necessary to contain future water wars. Virtual water need not be limited to agricultural output, but can also be applied to all other products and services. Across nations, all organizations, farmers and consumers should be accounted for the Virtual Water ...

Methodology to elaborate the bathing water profile on urban beaches, according to the requirements of the European Directive 2006/7/EC: the case of Santander beaches (Spain)
The approval of the current Bathing Water Directive (Directive 2006/7/EC) set the necessity to define the bathing water profile. The goals established in the definition of the profile are: (i) to know the processes that determine the concentration of bacteriological indicators in the aquatic environment, (ii) to obtain relationships between the cause of pollution and its effects, and (iii) to ...

Designing robust water planning institutions in remote regions: a case of Georgina and Diamantina catchment in Australia
Several catchment-based water planning processes are currently underway in Australia, with the Water Reform Agreement of 1994 providing the legislative umbrella. This paper presents the results of a case study conducted in the joint catchment of the Diamantina and Georgina rivers, located in the remote central-west part of the state of Queensland. The paper investigates the new water planning ...

Can Dowsing Rods Locate Water Supplies?
Finding water in the 21st century really isn’t all that difficult. We turn on the tap and out it streams, without so much as a second thought. However, it hasn’t always been that easy and – although we’re now blessed with a solid pipe network and other infrastructure that brings us what we need when we need it – in times past, civilisations had to rely on other ways ...
