Guidance on Environmental Flows : Integrating E-flow Science with Fluvial Geomorphology to Maintain Ecosystem Services
Fluvial systems provide a wide range of necessary services for human society to thrive on. These are the so-called ecosystem services: food, drinking water, natural flood mitigation, energy and so forth. Such services are linked to an appropriate level of functionality of fluvial processes, which can be accounted for in terms of ecological objectives. These ecological objectives in watercourses can be reached only if appropriate flow and sediment regimes and related quality of channel morphology are guaranteed. The establishment and maintenance of such flow regimes, namely environmental flows ...Guide to Instruments and Methods of Observation
The first edition of this guide was published in 1950.

Guidance on Verification of Operational Seasonal Climate Forecasts
The purpose of this publication is to describe and recommend procedures for the verification of operational probabilistic seasonal forecasts, including those from the Regional Climate Outlook Forums (RCOFs), National Meteorological and Hydrological Services and other forecasting centres. The recommendations are meant to complement the WMO Commission for Basic Systems Standardized Verification System for Long-range Forecasts (SVSLRF). SVSLRF defines standards for verifying model outputs from Global Producing Centres (GPCs), and so includes procedures for measuring the quality of ensemble predic ...

Guide de l'assistance météorologique aux activités maritimes
La connaissance des conditions météorologiques tient depuis toujours une place essentielle en matière de sécurité et d’efficacité appliquées aux activités maritimes, notamment le transport et la pêche. Au début du XXe siècle, avec l'apparition de la télégraphie sans fil, il devient possible d'établir des communications régulières entre les navires et la côte; c’est le commencement des émissions météorologiques pour la navigation maritime. La première Convention internationale pour la sauvegarde de la vie humaine en mer (Convention SOLAS) préconisait que la radiodiffusion de renseignements mété ...
