Flood Management Tool Series, Technical Document, 08. Risk Sharing in Flood Management
Flood managers have traditionally focused on structural interventions that, in the majority of cases have succeeded only in shifting impacts downstream or upstream. Meanwhile, however, the analytical tools for flood risk assessment and risk management practices offer a far greater variety of options. The Tool introduces the topic based on a judicious combination of measures that address risk reduction, risk retention and risk transfer through a strategic mix of structural and non-structural measures for flood preparedness, response and recovery. Risk reduction options also include the question ...
Flood Management Tool Series, Technical Document, 17. Coastal and Delta Flood Management
Coastal flood hazards are diverse (storm surges, tsunamis, tropical storms, seiches etc.) and are highly unpredictable. A profound understanding of these hazards, their mechanisms and potential impacts is therefore indispensable in order to derive an appropriate risk management response.
Such response should be selected from the widest range of measures and policies possible, taking due account of the inherent uncertainties both with respect to the probability of hazard and evolving socioeconomic developments.
This Tool paper aims at providing practical guidance to flood ...
Flood Management Tool Series, Technical Document, 18. Transboundary Flood Management
As floods do not recognize borders, transboundary flood risk management is imperative in shared river basins, involving both Governments – as borders are involved – and their people – as risk is involved. However, transboundary flood management is not easy to implement, as joint monitoring, forecasting and early warning, coordinated risk assessment and joint planning of measures, and appropriate legal and institutional frameworks are all necessary. The tool on transboundary aspects of flood management focuses on common problems, objectives and approaches of flood management in transboundary ba ...
Flood Management Tool Series, Technical Document, 19. Flood Forecasting and Early Warning
Flood forecasting and early warning is carried out to reduce risks in flood prone areas. This tool is tailored for use when decision‐makers need to establish an effective overview of the flood situation, provide timely and accurate early warnings and flood forecasting services to a variety of users. Many countries have already integrated flood forecasting and early warning measures into their local and national emergency planning systems. This tool provides a concise overview of concepts and approaches in flood forecasting and early warning that help flood managers and practitioners to develop ...
Flood Management Tool Series, Technical Document, 20. Flood Mapping
Flood Maps are tools to visualize flood information for decision makers and the general public. These maps form the basis for developing flood risk scenarios based on land use, various environmental and climate conditions and including social and economic conditions. Flood maps in their various formats and scales are the basis for the planning and implementation of development alternatives. In addition to the general objective of a flood map, special uses require specific information including maps that depict exposure to floods of various recurrence periods, flood risks, vulnerability and res ...
GCOS, 170. The GCOS Reference Upper-Air Network (GRUAN): Manual
This GCOS (Global Climate Observing System) Reference Upper‐Air Network (GRUAN) Manual describes mandatory operating protocols (distinguished by use of the words “must” or “shall”) which describe what is expected of participating sites, the GRUAN Lead Centre, and the Working Group on GRUAN (WG‐GRUAN) to achieve the goals of GRUAN. These protocols have the status of requirements in a technical resolution, which sites within GRUAN are expected to follow or implement.
Flood Management Tool Series, Technical Document, 13. Conservation and Restoration of Rivers and Floodplains
The tool aims at assisting practitioners mainly through reviewing and describing options for conservation and restoration of rivers and floodplains that can potentially assist flood management practitioners in addressing various flood management objectives, and providing an overview of current practices that could help flood management practitioners in identifying and establishing the values of ecosystem services generated under different conservation, restoration and flood management scenarios.
Flood Management Tool Series, Technical Document, 14. Urban Flood Management in a Changing Climate
The main thrust of this tool is to examine major aspects of urban flood management through in the context of climate change. This document deals with the “management” process and less about the technical, structural, and capital-intensive strategies usually pursued in coping with urban floods. It also explores the vital interaction and necessary overlap of urban flood management with land use management, urban planning, socio-economic development, and public awareness and participation. All of these issues lie at the core of planning for and carrying out strategies for climate change adaptatio ...
Flood Management Tool Series, Technical Document, 15. Flood Proofing
This tool aims to provide various options of flood proofing measures, not exclusively limited to structural measures or building protections, with a target of practitioners responsible for flood management. The tool covers two aspects of flood management: flood resistance and flood resilience. The flood resistance keeps out flood water to prevent flood damages, while flood resilience minimizes the impacts of floods once flooding occurs.
Flood Management Tool Series, Technical Document, 16. Management of Flash Floods
This tool provides an overview of approaches and practical actions to reduce disaster risks associated with flash floods. Flood forecasting and warning are expected to play an important role in flash flood management though there are scientific and technical limits to provide accurate and timely warnings. Spatial planning and flood proofing can also reduce risk of exposure. These require flood hazard mapping to assess the risk of flash floods and an appropriate legal framework to integrate (flash) flood management planning and spatial planning. Participatory approach can identify areas at risk ...
Guide to Agricultural Meteorological Practices (GAMP)
The 2010 Edition of this guide has been completely revised and updated. It provides information regarding the most important practices and procedures in agricultural meteorology.
Manual on Marine Meteorological Services - Volume I — Global Aspects : Annex VI to the WMO Technical Regulations
This manual is designed to facilitate cooperation in respect of the international coordination of marine meteorological services (MMS); to specify obligations of Members in the implementation of MMS; and to ensure uniformity in the practices and procedures employed in achieving these. It also aims to facilitate the development of adequate support from World Weather Watch (WWW) to MMS.
Standardized Precipitation Index User Guide
Over the years, there has been much discussion on what drought indices should be used in a particular climate and for what application. Many drought definitions and indices have been developed and attempts have been made to provide some guidance on this issue.
We hope that this user guide on the Standardized Precipitation Index will help countries and institutions to understand how to calculate and use the SPI in order to develop or further enhance their own drought monitoring and early warning capabilities.
A User’s Guide for Installation and Use of FY-3 MPT/HRPT Data Preprocessing Software Packages for Linux Users
On 27 May 2008, the China Meteorological Administration (CMA) successfully launched the FY-3 polar orbiting meteorological satellite through its partners. While making the Earth observations, FY-3 continuously broadcasts within its coverage the raw MPT data (from MERSI instrument), which is packed in CCSDS format and raw HRPT data from all its payload instruments (with only exception of MERSI instrument) via both X and L transmission bands. To extensively share the FY-3 data, the National Satellite Meteorological Center/CMA has released 2 software packages oriented to Linux users: (1) FY3L0pp ...
