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....
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
An optimization procedure for the sustainable management of water resources
The sustainable management of water resources requires the identification of procedures to optimize the use and management of resources that are able to deal adequately with the problems of an integrated water service. Taking cue from the classic problem of transport of operations research, this paper proposes a procedure to optimize the allocation of resources for water supply in an area. The transportation problem has been particularized to the case of water resources management considering water intake structure...
Determination of total vanadium and vanadium(V) in groundwater from Mt. Etna and estimate of daily ...
Vanadium(V) can be found in natural waters in the form of V(IV) and V(V) species, which have different biological properties and toxicity. The purpose of this study was to determine the concentrations of total V and V(V) in groundwater from the area of Mt. Etna and to assess the estimated daily intake (EDI) of V(V) of adults and children through drinking water. Water was sampled monthly at 21 sites in 2011. Total vanadium was determined by inductively coupled plasma-mass spectrometry (ICP-MS) and speciation by...
