The Commission for Hydrology on its 14th session has among other activities asked for:
Preparation of a note/overview guidance material on how to use regional climate modeling (i.e. long-term climate scenarios) in strategic hydrological management
Preparation of a comprehensive report on downscaling approaches for hydrological applications and their associated uncertainties, including commenting on existing case studies
A group of experts met to discuss the document structure and steps in its preparation in Geneva last week. We agreed to prepare document that is intended to support operation and practice of National Hydrological Services (NHSs) and other practitioners in the field of use of outputs of climate models for hydrological applications. As such the main aim of the document is to provide a guidance on the process of design and performance of the climate model outputs use in hydrological applications e.g. climate change impact studies or seasonal hydrological predictions.
Our target user groups are practitioners in the field of hydrology and water management. Therefore the whole document describes and handle various aspect from the perspective of an impact modeler not a climate expert. The climate model outputs are considered as delivered products and inputs to the impact study or hydrological model.
The discussion led to a proposal of following table_of_contents.
You are welcome to comment on the document structure represented by table of contents as soon as possible. You are also welcome to express your interest to contribute to document preparation e.g. By provision of examples of case studies or trough the internal review of selected chapters.
