The algorithms were applied to the data related to the Karun-e-Bozorg basin in Iran. The results showed that joining a flood statistic with an appropriate weight to the feature vectors used in regionalization may improve the results of regionalization according to the number of the watersheds assigned to the homogeneous regions. Transbasin diversions and dams allow for water uses when and where there is high demand and low supply, but can come with an expense to the environment. This paper presents a linkage of hydrologic and hydraulic modeling and datasets to assess the hydrologic and hydraulic stability within a transbasin watershed as an approach for meeting water use targets and safeguarding environmental.
Hydrological regionalization is a useful step in hydrological modeling and prediction. The regionalization is not always straightforward, however, due to the lack of long-term hydrological data and the complex multi-scale variability features embedded in the data. This study examines the multiscale soil moisture variability for the simulated data on a grid cell base obtained from a large .

Abstract. There are various methods available for annual groundwater recharge estimation with in situ observations (i.e., observations obtained at the site/location of interest), but a great number of watersheds around the world still remain ungauged, i.e., without in situ observations of hydrologic responses. One approach for making estimates at ungauged watersheds is regionalization, namely.

Introduction. Hydrological data have always played a fundamental role in the planning Regionalisation of hydrological data book formulation of sound policies for the sustainable management of water resources; this role has become even more crucial in today’s environment, where competition among water users is increasing and hydrological networks are found to be either declining or by: Journal of Hydrology, 73 () 71 Elsevier Science Publishers B.V., Amsterdam -- Printed in The Netherlands [51 A SYSTEMATIC PROBLEM-ORIENTED APPROACH TO HYDROLOGICAL DATA REGIONALISATION I.

A prediction in ungauged basins is one of the challenging tasks for a hydrologist of this century. Even though the physically based hydrological models can be the more appropriate in ungauged basins but data requirement limit the use.
Conceptual hydrological models are simple and easy to use. But these model needs calibration before it can be : Shailesh Kumar Singh.
A regionalization of hydrological model parameters on the basis of catchment characteristics is therefore plausible. However, due to the non-uniqueness of the rainfall/runoff model parameters (equifinality), a procedure of a regional parameter estimation by model calibration and a subsequent fit of a regional function is not by: 9.

However, most studies had a regional (subcontinental) focus, employed a relatively small number of catchments, and used a variety of hydrologic models, forcing data, regionalization approaches, objective functions, and evaluation methodologies, resulting in findings with questionable generalizability [Razavi and Coulibaly, ].

While most books examine only the classical aspects of hydrology, this three-volume set covers multiple aspects of hydrology, and includes contributions from experts from more than 30 countries.
It examines new approaches, addresses growing concerns about hydrological and ecological connectivity, and considers the worldwide impact of climate change. It also provides updated material. In West Africa, the general situation of insufficient data is exacerbated by the decline of the measuring network observed since the late eighties.
With the aim of predicting hydrological variables in ungauged basins, regionalization methods are usually used. Integrated Hydrological Data Book, Chapter 1 Introduction The Annual precipitation including snowfall is the main source of water in India and is estimated to be of the order of cu km.
The total water resource potential of the country. These curves are important to estimate the flood quantiles of ungauged catchments in the data scarce area of the basin; hence, they meet the needs of water engineers who currently face tremendous challenges in designing small and medium hydraulic structures in the basin.
Hydrological regionalization is an important tool for the analysis of the spatial pattern of variations in hydrological phenomena. Regionalization means areal classification, i.e. the ability to attach to some location a label or number which is hydrologically meaningful.

The application of data mining techniques for the regionalisation of hydrological variables Question (1) is a matter of classification, whereas (2) requires the modelling of dependencies. Perhaps the most widely-applied procedure for hydrological regionalisation applied to date has been the so-called Method of Residuals.

Regionalisation has long been used as a standard tool to facilitate extrapolation from sites at which records have been collected to others at which data are required but unavailable. The need for such information has escalated dramatically in recent years to the point where the procedure has become a standard prerequisite for adequate solution of innumerable water-resource management problems.
The variables used in the creation of the hydrological regionalisation. A number of variables describing the storage, transport and release of surface water, groundwater and atmospheric water were included in the analysis.

Hy- drological investigations are encouraged at the national, regional and. The Hilbert-Huang Transform ((HHT) is a recently developed technique which is used to analyze nonstationary data. Hydrologic and environmental series are, in the main, analyzed by using techniques which were developed for stationary data.
This has led to problems of interpretation of the results. Environmental and hydrologic series are quite Format: Hardcover. Availability of data at all location in the basin limits the calibration of conceptual hydrological models. In this book a calibration methodology is presented for discharge series limited condition using upstream and downstream data.
