Derivation of Instantaneous Unit Hydrograph for a sub-basin using Linear Geomorphological Model and Geographic Information Systems
Geographic Information System GIS Linear Geomorphological Model LGM GIUH
2015/8/14
Rainfall is converted into runoff and reaches the river and it becomes river flow. Geomorphological Instantaneous Unit Hydrograph (GIUH) based approach, which uses the geomorphologic parameters, is us...
Forest watershed runoff changes determined using the unit hydrograph method
forest watershed drainage runoff
2015/3/17
Unit hydrograph is a basic method to show changes in runoff in the watershed. The investigation of runoff changes was carried out in the U Dvou louček watershed situated at the summit part of the...

Much attention has been given to rationalizing the dimensionless unit hydrograph
during the past two decades. Recently, Schultz, Pinkayan & Komsartra
(1971) reviewed some of this literature and prop...
A Comparison of Some Methods of Deriving the Instantaneous Unit Hydrograph
Comparison Some Methods Instantaneous Unit Hydrograph
2009/10/28
The geomorphological instantaneous unit hydrograph (IUH) proposed by
Gupta et al. (1980) was compared with the IUH derived by commonly used
time-area and Nash methods. This comparison was performed ...
Distributions of Instantaneous Unit Hydrograph Peak Characteristics for Small River Networks
Instantaneous unit hydrograph river network width function translation routing
2009/10/14
Diameter-conditioned distribution functions of peak ratio (\peak"/diameter) and position ratio (\time to peak"/diameter) of topological width functions of small networks were obtained analytically. He...
A SPATIALLY VARIED UNIT HYDROGRAPH MODEL
instantaneous unit hydrographs flood hydrographs geomorphology
2009/10/13
In the recent past, instantaneous unit hydrographs based on geomorphology have been proposed as a tool to produce flood hydrographs from rainfall. This paper presents a flood hydrograph simulation mod...
Linear Reservoirs in Series Model for Unit Hydrograph of Finite Duration
Unit hydrograph Linear reservoirs Reservoirs in series
2009/10/12
The unit hydrograph of a river basin can be estimated from the records of rainfall and streamflow by various methods. In this paper, a linear reservoirs in series model is used to derive the unit hydr...
The geomorphological unit hydrograph – a critical review
geomorphological unit hydrograph instantaneous unit hydrograph
2009/5/27
The theory of the geomorphological unit hydrograph (GUH) is examined critically and it is shown that the inherent assumption that the operation of the drainage network may be modelled by a correspondi...

The construction of design flood hydrographs for ungauged drainage areas has traditionally been approached by regionalisation, i.e. the transfer of information from the gauged to the ungauged catchmen...
Improved unit hydrograph characterisation of the daily flow regime (including low flows) for the River Teifi, Wales: towards better rainfall-streamflow models for regionalisation

2009/3/17
An established rainfall-streamflow modelling methodology employing a six-parameter unit hydrograph-based rainfall-runoff model structure is developed further to give an improved model-fit to daily flo...
