The Imperative of Water Resources Assessment
Bulletin nº Vol 57 (3) - 2008
1

As populations grow and economies expand, competition for water to meet household, municipal, agricultural and industrial needs continuously increases. Moreover, laws and regulations aimed at keeping water in rivers and streams to meet environmental and recreational objectives are similarly increasing.
Developments in Hydrometric Technology: New and Emerging Instruments for Mapping River Hydrodynamics
Bulletin nº Vol 57 (3) - 2008

Publish Date: 1 July 2008
New demands on surface-water resources from an increasing world population and rising global living standards are requiring water managers to improve river flow measurements. Water managers are requiring flow instrumentation to measure those resources more accurately, in more detail and at lesser cost.

Communicating Forecast Uncertainty for Service Providers
Bulletin nº Vol 57 (4) - 2008
1
Publish Date: 1 October 2008
by Jon Gill Uncertainty is an inherent ingredient in the hydrometeorological forecasting process. Forecasters are familiar with the question of uncertainty and predictability and must deal with it every time a forecast is prepared. Sometimes, the available computer models or other guidance are consistent in their predictions and the forecaster is confident of the outcome. At other times, the models may differ greatly or the weather parameter may be intrinsically difficult to forecast. Nevertheless, a forecast must be made, even when confidence is low.
Partnership between Private and Public Sectors in Service Delivery
Bulletin nº Vol 57 (4) - 2008

Publish Date: 1 October 2008
by Neil Gordon A number of factors have led to many National Meteorological Services becoming involved in the provision of value-added services, in addition to their core government-funded role. These include trends since the 1980s and 1990s for government bodies to take a more “business-like” approach, financial pressures on NMSs causing them to seek additional revenue sources, and an increasing ability for NMSs to add value to the core publicly funded services they already produce.
Economic Valuation and Application of Services

by Jeffrey K. Lazo, Nathaniel F. Bushek, Emily K. Laidlaw, Robert S. Raucher, Thomas J. Teisberg, Carolyn J. Wagner and Rodney F. Weiher Measuring the economic impact of hydrometeorological services and information typically involves assessing the impact of hydrometeorological events or forecasts of events on specific economic sectors such as trans­portation, energy or agriculture. Changes in measures of output, employment, revenue or taxes are presented as the economic impacts of these events or forecasts.
Public Health and Weather Services–Climate Information for the Health Sector

by T.A. Ghebreyesus, Z. Tadese, D. Jima, E. Bekele, A. Mihretie, Y.Y. Yihdego, T. Dinku, S.J. Connor and D.P. Rogers Climate is a key variable in managing the overall burden of disease, particularly in developing countries where the ability to control climate-sensitive diseases constrains the prospects of achieving the United Nations Millennium Development Goals. To mitigate their adverse effects, the health sector needs to understand and quantify the specific effects of climate variability and change both on the overall disease burden and on opportunities and effectiveness in the public...
