Operational hydrology report (OHR), 21. Methods of correction for systematic error in point precipitation measurement for operational use
This publication, in the form of an operational manual, describes methods of correcting errors with diagrams, formulae, a detailed chronology and over 100 references. The long-term aim is the wider acceptance and use of internationally recognized methods of correcting precipitation data.
Operational hydrology report (OHR), 20. Long-range water-supply forecasting
Regression methods, conceptual models and time series are reviewed and compared, and the feasibility of combining conceptual deterministic models and data simulation is discussed.
Operational hydrology report (OHR), 19. Concepts and techniques in hydrological network design
The concept of an optimum network is adapted to achieve a realistic network design based on surrogate measures, objectives and criteria. Supportive decision theory is then developed, based on the various design components involved, such as socio-economic analysis, probability theory, Bayesian analysis, etc.
Operational hydrology report (OHR), 18. Flash flood forecasting
This report reviews the problem of flash floods and summarizes the basic forecasting techniques and warning systems as well as non-real-time solutions.
Operational hydrology report (OHR), 16. Measurement of river sediments : prepared by the Rapporteur on Sediment Transport of the Commission for Hydrology
This report is a review of equipment and techniques for measuring sediment discharge in alluvial rivers. After an introductory discussion on classifying river sediments, there is an examination of the measurement of suspended sediment, bed load and total load and the sampling of bed material.
Operational hydrology report (OHR), 15. Selection of distribution types for extremes of precipitation
Reviewed are methods of selecting distribution types for the analysis of extremes of precipitation and results obtained, bearing in mind the effects of climate, seasonal and geo-graphical patterns and the duration of precipitation. A practical example is included.
Operational hydrology report (OHR), 14. Hydrological data transmission
Deals with current hydrological data transmission systems in connection with flood forecasting and warning dissemination, data collection and processing and describes ways of meeting the requirements of National Hydrological Services, with particular emphasis on satellites.
Operational hydrology report (OHR), 17. Case studies of National hydrological data banks (planning, development and organization)
Fourteen countries contributed information on the planning, development and organization of their national hydrological data banks, according to an annotated guideline provided to them.
Operational hydrology report (OHR), 12. Applications of remote sensing to hydrology
World Meteorological Organization (WMO) ; Konovalov V.G.; Solomon S.I.; et al. - WMO, 1979 (WMO-No. 513)This report, prepared by WMO and UNESCO, describes briefly the principles and techniques of remote sensing for the collection of data on surface waters and related water-balance elements. It discusses the nature of the results obtained as well as their application.
Operational hydrology report (OHR), 11. Hydrological application of atmospheric vapour-flux analysis
