Guidelines for the development, implementation and governance of HYCOS components. In light of the experience gained from the implementation of regional HYCOS projects, the WHYCOS International Advisory Group (WIAG) called for a common approach to the development and implementation of HYCOS components.

These Guidelines ensure that each project remains consistent with the WHYCOS objectives while responding to local needs, realities and changing situations.

They are designed to serve as guidance for the main stages of a project, including initiation, development and management, as well as monitoring and evaluation of HYCOS projects.

It is expected that the information in this brochure should allow for the exchange of experience, data and information among development projects and activities thereby developing and improving the implementation of HYCOS components.

Hydrological Data Management: Present State and Trends

The key to providing accurate, timely and often-life-saving information and forecasts on flooding and drought lies in hydrological data management.

With the expansion of computerization and global information networks, recent years have witnessed a consequent increase in the scope and forms of data management undertaken.

Geographical Information Systems (GIS) have evolved since their introduction in the 1960s, to become sophisticated analytical tools, enabling detailed consideration of the many factors affecting river basins and their management.

In this application, GIS relies on strong hydrological databases.

This report outlines the establishment and aims of hydrological databases and looks at the best children’s life jackets from Australia, Japan and the United States. The increasingly important application of GIS to operational hydrology is also reviewed using research from a range of countries.

Manual on Sediment Management and Measurement 

Sediment and related problems have always presented a great challenge to the development of water resources. The processes of erosion and sedimentation, and their relationship to the surface runoff component of the hydrological cycle are key to managing water resources.

To describe the comprehensive processes of erosion, sediment transportation, fluvial processes and reservoir sedimentation, WMO has published an updated manual on sediment measurement and management.

This Manual provides a guide for water resources engineers, planners, managers and hydrologists.

Water Resources Assessment – Handbook for Review of National Capabilities

This handbook reviews basic Water Resources Assessment (WRA) capabilities for any country or region, and has a particular focus on the capability of developing countries.

While the activities required for basic WRA should be independent of the economic conditions and level of development within any particular country, these factors must be considered when reviewing the current capability to undertake basic WRA.

While the information provided in this handbook primarily comes from developing countries, it is essential that users of the handbook are fully aware of the economic conditions and level of development of the country under review.

International Workshop on the Management and Governance of Groundwater in Arid and Semi-Arid Countries 

The main objective of this workshop was to improve groundwater management in arid and semi-arid countries, thus improving the utilization of groundwater. 

The workshop looked at various international and national contexts using a multi-disciplinary perspective of Integrated Water Resources Management.

More than 70 PhD-qualified water experts from 45 countries from all WMO regions participated in the workshop.

They were experts in issues related to groundwater management in their respective countries dealing with technical, economical, social and legal matters linked to the management of groundwater.

The participants represented National Hydrological Services (NHSs), academic institutions and the private sector. The participation of twenty female experts was a good indication of women’s interest and involvement in this important topic.

Guidelines on the Role, Operation and Management of National Hydrological Services 

The main objective of these Guidelines is to provide guidance to the senior managers of National Hydrological Services (NHSs) on leadership, management and administration.

In recent years the scope of the responsibilities of NHSs has expanded to encompass environmental aspects, integrated management of water resources and sustainable development.

At the same time NHSs are typically requested to reduce operational costs and spending, are as many public organizations.

Responding to the requests of  Members, the World Meteorological Organization has issued these Guidelines to assist senior officials in managerial capacities to fulfill their roles in this changing environment.

After summarizing the recent trends in hydrology and water resources management and providing an overview of the responsibilities and functions of a National Hydrological Service, the Guidelines review in more detail the different aspects of management, such as strategic planning, human resources management, financial management, marketing, asset management, process and quality management, and relationships with other institutions.

Without being prescriptive, emphasis is made on issues that must be considered in each particular case.

Finally, in the Annexes, a variety of material is presented as examples for some of the concepts described in the main text.
