Classification of Spatio - Temporal Pattern of Rainfall in Iran Using a Hierarchical and Divisive Cluster Analysis
Rainfall pattern Cluster Analysis Ward Method Iran
2015/8/11
The identification of spatial rainfall pattern is an essential task for hydrologists, climatologists as well as regional and local planners and managers. This is due to the variability of both the tem...
A stochastic design rainfall generator based on copulas and mass curves
rainfall generator copulas mass curves
2010/12/22
The use of design storms can be very useful in many hydrological and hydraulic practices. In this study, the concept of a copula-based secondary return period in combination with the concept of mass c...
Limits and characteristics of the multifractal behaviour of a high-resolution rainfall time series
multifractal behaviour high-resolution rainfall time series
2009/11/16
The multifractal properties of a 2-year time series of 8-min rainfall intensity observations are investigated. The empirical probability distribution function suggests a hyperbolic intermittency with ...
Meteorological uncertainty and rainfall downscaling
Meteorological uncertainty rainfall downscaling
2009/11/3
We explore the sources of forecast uncertainty in a mixed dynamical-stochastic ensemble prediction chain for small-scale precipitation, suitable for hydrological applications. To this end, we apply th...
Multiscaling analysis of high resolution space-time lidar-rainfall
Multiscaling analysis high resolution space-time lidar-rainfall
2009/10/30
In this study, we report results from scaling analysis of 2.5 m spatial and 1 s temporal resolution lidar-rainfall data. The high resolution spatial and temporal data from the same observing system al...
Analysis of the Rainfall-Runoff Transformation Process

2009/10/28
Considerable effort has been expended on the theoretical aspects of the applicability
of the unsteady flow equations to natural overland flow. The major
difficulty when these equations are used to s...
The shape of a runoff hydrograph depends on the dynamic properties of the
rainfall. The possible range of impact of the rainfall movement on runoff
generating process can only be judged if the rainf...

Investigation Influence of Rainfall Movement Runoff Hydrograph Real Catchments
2009/10/28
Work presented here consists of two parts: the first part, presented before as a
separate paper (Niemczynowicz 1984b), described studies performed on conceptual
catchment, the secoGd part presented ...

Investigation Influence of Rainfall Movement Runoff Hydrograph Conceptual Catchment
2009/10/28
Work reported here consists of two parts: the first part describes studies
performed on a conceptual catchment, the second part, presented as a separate
paper, describes studies on real catchments i...
Analysis of Non-Linear Rainfall-Runoff Process
Analysis Non-Linear Rainfall-Runoff Process
2009/10/27
Rainfall runoff phenomena in small watersheds are favorably modelled using
the kinematic wave approach. The present investigation considers excess rainfall
as time dependent but ignores spatial effe...
The speed and direction of movement of rainfall patterns, assumed constant
during any given storm, can be derived from data sets comprised of the coordinates
(x, y) of a number of rainfall recording...
Effects of Spatially-Distributed Rainfall on Runoff for a Conceptual Catchment
Spatially-Distributed Rainfall Runoff Conceptual Catchment
2009/10/26
A physically-based rainfall-runoff model is used to investigate effects of moving
storms on the runoff hydrograph of throughflow dominated idealised catchments.
Simulations are undertaken varying th...
EFFECTS OF RAINFALL VARIABILITY ON SPATIAL ACCUMULATION OF PEAK RUNOFF AND EXCESS RUNOFF DEPTH: LITTLE WASHITA RIVER BASIN, OKLAHOMA, USA
surface runoff components runoff depth peak flow
2009/10/19
This paper demonstrates the spatial variability of surface runoff components, accumulated peak flow (Q a ) and excess runoff depth (R a ), in response to varying distribution of precipitation on a bas...
Constraints of artificial neural networks for rainfall-runoff modelling：trade-offs in hydrological state representation and model evaluation
neural networks rainfall-runoff modelling
2009/5/18
The application of Artificial Neural Networks (ANNs) in rainfall-runoff modelling needs to be researched more extensively in order to appreciate and fulfil the potential of this modelling approach. Th...
