In order to obtain information on the hydrological signature of rivers during and after heavy rain events, small
catchment areas are selected as experimental sites. Hydrograph separations based on en...
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...

Advances in scientific knowledge and new techniques of remote sensing permit a better understanding of the physical land features governing hydrologic processes, and make possible efficient, large-sca...
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...
Regional analysis using the Geomorphologic Instantaneous Unit Hydrograph (GIUH) method
Ammameh catchment geomorphologic and geomorphoclimatic instantaneous unit hydrographs rainfall-runoff model regionalization
2015/3/10
The construction of design flood hydrographs for ungauged drainage areas has traditionally been approached by regionalization, i.e. the transfer of information from the gauged to the ungauged catchmen...

Time Step Issue in Unit Hydrograph for Improving Runoff Prediction in Small Catchments
Unit Hydrograph Time Step Peak Discharge Time to Peak
2013/3/19
Unit hydrograph is a very practical tool in runoff prediction which has been used since decades ago and to date it remains useful. Unit hydrograph method is applied in Way Kuala Garuntang, an ungauged...
Groundwater Hydrograph Patterns in North China Plain during 1982-1986 Interpreted Using Principal Component Analysis
Groundwater Depth, North China Plain, Principal Component Analysis (PCA)
2011/12/16
The groundwater table depths from 1982 to 1986 of 58 unconfined wells in North China Plain(NCP) were analyzed using principal component analysis method. Results showed there were mainly three hydrogra...
Z-Transform Based Instantaneous Unit Hydrograph for Hilly Watersheds
IUH ARMA Process Z-Transform Nash Model Direct Runoff Hydrograph Hilly Watershed
2013/3/21
Present study emphasizes the applicability of linear theory concept onto hilly watersheds. For this purpose, Z-transform technique was used to derive the instantaneous unit hydrograph (IUH) from the t...
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...
