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 (3-D) hydrodynamic and salinity numerical model is built. Critical runoff–tide level lines are obtained to determine the occurrence of saltwater intrusion. To quantify the guarantee rates of freshwater, copula joint distribution is utilized, which connects the numerical model and daily hydrological characteristics. Guarantee rates of freshwater are obtained under different amounts of water intake (0, 10 m3/s, 20 m3/s, 30 m3/s). In addition, critical locations of water intake that satisfy different guarantee rates (80%, 85%, 90%, 95%, 99%) are identified. All the results will provide technical support for risk evaluation of saltwater intrusion and decisions on water intake location.
ITOXcontrol safeguards intake Romanian drinking water Case Study
The Romanian water supply company Apavital has installed a monitoring station to safeguard the intake of water from the river Prut. The monitoring station is part of an integrated monitoring that signals sudden changes in the water quality of the rivers, enabling Apavital to take appropriate measures, in the worst case a stop of the intake. The iTOXcontrol is developed by the Dutch company microLAN that has installed almost 100 stations worldwide, safeguarding the water supply in cities such as Amsterdam, Washingto...
Seasonal patterns of drinking water consumption pattern in Mysore City, Karnataka, South India
The aim of this study is to determine the general drinking water consumption pattern in Mysore city, Karnataka, South India with special reference to cold water (without boiling), and to construct a data base for water consumption habits of Mysore people. In developing countries microbial risk assessment studies, water intake values are often adopted from developed countries. However, these values may not be suitable for the risk characterization of human populations from tropical regions of developing countries....
Optimal control of reservoir release temperature through selective withdrawal intake at hydropower ...
This study is motivated by the need to understand the temperature dynamics and warm-water temperature withdrawal. This study also recognizes the need for an environmental assessment of the proposed temperature control schemes at New Fengman Dam. An unsteady three-dimensional (3D) non-hydrostatic model is used in the present study to predict the hydrodynamics and thermal dynamics in the forebay and intakes of the New Fengman Dam. The numerical model is validated using hydrodynamic data collected from a 1:120...
Nuclear power plant keeps intakes clean - case study
When this nuclear power plant in the Great Lakes region needed reliable traveling water screens to keep it’s intakes clean, they chose International Water Screens.Vertical screens with hoods provide clean water to create steam to generate up to 725,000 kilowatts of electricity for the surrounding region.This project included: Traveling Screen(s) Elevator Pump Trash Container Control Panel Head Loss Level Reader Filter Automatic Flash Filter Conveyor
Assessing the potential use of abandoned mining pools as an alternative resource of raw water supply
The water crisis in the state of Selangor has prompted the state water authority to use water from abandoned mining pools as an alternative resource of raw water supply. In this study, the potential use of the mining pool water has been assessed to evaluate its safe use for potable water consumption, which is the source of raw water to be supplied to water treatment plants. Assessments were made between sampling sites that include abandoned mining pools, active sand mining pools, and the receiving streams (two...
