Runoff Ratio, Preflood Discharge Rate and Rainfall Intensity of Daily Hydrologic Data

Interaction Effect of Slope Aspect and Precipitation Intensity in Runoff and Sediment in Acid Rainfall

Soils are severely damaged by acid rain; acid rain also leads to excessive dissolving of minerals and valuable nutrients in the soil, which weakens vegetation. In this study, in order to determine the interaction effect between the slope aspect and precipitation intensity relative to acid rainfall in the Aghajari and Gachsaran formations, a part of Margha and Kuhe Gach watersheds of Izeh city w...

Artificial neural networks for daily rainfall-runoff modelling

The application of artificial neural network (ANN) methodology for modelling daily flows during monsoon flood events for a large size catchment of the Narmada River in Madhya Pradesh (India) is presented. The spatial variation of rainfall is accounted for by subdividing the catchment and treating the average rainfall of each subcatchment as a parallel and separate lumped input to the model. A l...

Calibration of a Daily Rainfall-Runoff Model to Estimate High Daily Flows

Flood estimation can be performed on the basis of event-based simulation or continuous simulation. A model with continuous water balance accounting has the attractive feature that dynamic factors affecting runoff production may be represented explicitly (Lamb 1999). In particular, a conceptual rainfall-runoff model can simulate the changing antecedent moisture conditions that determine the catc...

Effect of vegetation cover ,slope, and rainfall intensity on runoff in some watersheds of chaharmahal and bakhtiary provience

Analysis of extreme daily rainfall in southeast Asia with a gridded daily rainfall data set

The objective of this study is to estimate the daily extreme precipitation distribution in an Asian monsoon region considering orographic precipitation in mountainous areas. For this purpose, the APHRODITE data set and precipitation observations from 150 raingauges throughout Thailand were used as the main input. First, a bias-correction for underestimated precipitation in the APHRODITE data se...
