The paper presents the state-of-the-art in flood forecasting and simulation applied to a river flood analysis and risk prediction. Different water flow forecasting and river simulation models are analysed. An advanced river flood forecasting and modelling approach developed within the ongoing project INFROM is described. It provides an integrated procedure for river flow forecasting and simulat...

Interfaces are ubiquitous. They occur everywhere. They are the boundaries that separate distinct physical and chemical regions of matter. The bulk materials on adjacent sides of the interface can be chemically identical, as with a liquid water/vapor water interface, or they can be chemically different, as at ~t liquid/liquid interface such as hexadecane/water. All transfers of chemical species ...

It may be difficult for small and medium cities to obtain information about the fluoride content of public water, because of the lack of equipments and technicians. This study aimed to analyze the fluoride levels of the water supplied by the public treatment stations of 40 cities situated in the northwest region of São Paulo State, during a period of 6 months, to verify if fluoridation occurs i...

Sensitivity analysis for water vapor profile estimation with Infrared: IR sounder data based on inversion is carried out. Through simulation study, it is found that influence due to ground surface relative humidity estimation error is greater than that of sea surface temperature estimation error on the water vapor vertical profile retrievals. KeywordsIR sounde; error budget analysis; MODTRAN; a...

Narrow-band detection of the Raman water vapor spectrum using the lidar technique introduces a concern over the temperature dependence of the Raman spectrum. Various groups have addressed this issue either by trying to minimize the temperature dependence to the point where it can be ignored or by correcting for whatever degree of temperature dependence exists. The traditional technique for perf...

The Buchanan County Board of Health (BCBOH) has reviewed and discussed the relevant facts on the issue of community water fluoridation (CWF). Subsequent to that review and discussion, the BCBOH has unanimously adopted the position which supports CWF. It is the Board’s conclusion that the science supports the current practice as sound public health policy which protects and preserves the health ...

The Water Framework Directive (WFD) imposes a new approach to water resource management in the EU states. Uncertainty surrounding its implementation, however, could badly affect the achievement of the objectives set by the Directive. Although not directly linked to a set of techniques to deal with it, the WFD and accompanying guideline documents identify uncertainty as a factor likely to play a...

International monitoring of drinking water and sanitation shapes awareness of countries' needs and informs policy, implementation and research efforts to extend and improve services. The Millennium Development Goals established global targets for drinking water and sanitation access; progress towards these targets, facilitated by international monitoring, has contributed to reducing the global ...

This chapter presents a comprehensive review of valuation of water. Though existing literature has a large number of papers on the significant attempts at valuing water, a number of publications only consider certain specific aspects of water pricing, rarely attempting a comprehensive review. Water pricing, whether by government mandate or in practice, has to take into consideration a host of c...
