Good practice guidelines for water data management policy : world water data initiative
Bureau of Meteorology ; World Meteorological Organization (WMO) - Australian Bureau of Meteorology, 2017These guidelines acknowledge that it is difficult to gather support for and then prosecute actions that are disruptive to the status quo and requiring considerable public investment. It is stressed that planning the water data reform journey is every bit as challenging as implementing the reforms themselves. Accordingly, these guidelines conclude with a recommended series of steps to get started in reforming water data management arrangements.

Comparison of different rainfall inputs in a continuous rainfall-runoff model – a case study for Argentina
Buzzella Maria Mercedes; Institute of Water Resources Management, Hydrology and Agricultural Hydraulic Engineering - Leibniz Universität, 2013Precipitation data is the main input parameter in order to simulate rainfall-runoff processes, since it is strongly dependent on the accuracy of the spatial and temporal representation of the precipitation. In regions where rainfall stations are scarce, additional data sources may be considered necessary. In this manner, remote sensing from satellite platforms has provided a satisfactory alternative due to its global coverage. Although a wide range of satellite-based estimations of precipitation is available, not all the satellite products are suitable for all regions. Most of the studies perf ...

Maria Mercedes Buzzella ; Institute of Water Resources Management, Hydrology and Agricultural Hydraulic Engineering
Published by: Leibniz Universität ; 2013Precipitation data is the main input parameter in order to simulate rainfall-runoff processes, since it is strongly dependent on the accuracy of the spatial and temporal representation of the precipitation. In regions where rainfall stations are scarce, additional data sources may be considered necessary. In this manner, remote sensing from satellite platforms has provided a satisfactory alternative due to its global coverage. Although a wide range of satellite-based estimations of precipitation is available, not all the satellite products are suitable for all regions. Most of the studies performed with the purpose of evaluating their accuracy are focused in particular areas of the world. In this fashion, particular models have to be conducted in order to evaluate their performances, specially in regions with complex geography as high mountains.
Additionally, to perform an appropriate spatial representation of the rainfall and consequently to improve the available data, interpolation techniques are used, e.g. simple techniques as Nearest Neighbour or Inverse Distance methods, and some more complex as geostatistical (Kriging) methods. This last one offers the advantage of adding relevant additional information in the interpolation, providing a chance to compensate a low network density. Moreover, in data scarce regions in which interpolation schemes are applied, it becomes difficult to have an accurate performance assessment; in this manner, other comparison tool is required as rainfall-runoff models.
In this manner, the aim of this study is to perform a comparison between different types of available rainfall data by means of a hydrological model. The work is focused in Neuquén catchment, a mountainous region of Argentina where several rainfall stations and flow gauges are available. In this fashion, a satellite-based estimated precipitation already validated in mountainous areas and southern latitudes, CMORPH, is used as well as the available rainfall stations as input. Moreover, to improve the rainfall stations measurements, CMORPH data and topography are used during the interpolation as additional variables. Consequently, five precipitation input cases are generated and compared. To accomplish the main objective, at first several interpolation techniques are tested and assessed by means of cross-validation for each precipitation input. Subsequently, a hydrological model HEC-HMS is set up for every case and thus its outcomes are compared using indices of reliability.
Regarding the cases that consider the rainfall stations data, assess from the interpolation technique showed that the best performance is obtained with the case without external drift. Conversely, the hydrological model showed the most accurate precision when topography was used as additional information. Input cases with the satellite-based estimations as external drift improved considerably the results in comparison to the case in which rainfall stations are considered alone. However, results showed that the case with CMORPH data as only input, the estimation of the observed discharge was not able to be reproduced precisely. Finally it could be concluded that, in those cases in which the rainfall stations networks are not dense enough and do not represent the spatial variability of the area correctly additional information is extremely useful to simulate more accurately the observed discharge in the area.Notes: Supervisor: Ana Claudia Callaú Poduje

However, global water resources are coming under increasing pressure. It is widely recognized that over the next few decades global drivers such as climate change, population growth and improving living standards will increase pressure on the availability, quality and distribution of water resources.

Managing the impacts of these drivers to maximize social and economic welfare will require intelligent policy and management responses at all levels of collection, production and distribution of water. The goal is to improve water allocation systems in order to balance multiple uses – including social, economic and environmental benefits – of water resources.

If the Price is Right- Development of a Methodology for Valuing Hydrologic Data : In 23rd Hydrology and Water Resources Symposium
Increasing restrictions on public funding for hydrologic data collection, and a trend over recent years for data collection activities to be driven by current specific use projects, have highlighted more than ever before the need to systematically assess the value of the benefits derived from the collection of hydrologic data. A most important aspect of this need is to make sensible, realistic estimates of the economic value of sll,ch benefits in dollar terms for current as well as for future uses of hydrologic data. Previous attempts to achieve this have been of limited practical application, ...

Operational hydrology report (OHR), 32. Cost-benefit assessment techniques and user requirements for hydrological data
In 1980 the Commission for Hydrology established a Working Group on Users' Requirements for Hydrological Information to study the determination of the economic value of hydrological data for water-resource projects and the use of cost-benefit criteria in the optimization of hydrological networks. The reports prepared by members of the group are presented in this publication together with the findings of an international Workshop on the Application of Cost-Benefit Assessment of Hydrological Data for Water-resource Projects held in Geneva in November 1982.
