The influence of the net rainfall mixed Curve Number – Green Ampt procedure in flood hazard mapping: a case study in Central Italy [PDF]

open access: yesJournal of Agricultural Engineering, 2013
A net rainfall estimation procedure, referred to as Curve-Number For Green-Ampt (CN4GA), combining the Soil Conservation Service - Curve Number (SCS-CN) method and the Green and Ampt (GA) infiltration equation was recently developed, aiming to distribute

Infiltration and stability analysis of gravelly soil slopes under rainfall with the improved green-ampt model [PDF]

open access: yesFrontiers in Earth Science
Rainfall infiltration is a key cause of slope instability, especially in complex soil-rock mixture slopes with preferential flow paths. The classic Green-Ampt model, widely used in infiltration studies, has limitations in handling air pressure variations

Coupling Green-Ampt and Saint-Venant Equations for Estimating of Transmission Losses during Flood Routing in Rivers [PDF]

open access: yesعلوم و مهندسی آبیاری, 2016
Volume of flooding flow volume in ephemeral streams decreases due to evaporation as well as the channel wall and bed penetration. This process is known as transmission losses.

Modification of Green-Ampt model based on the stratification hypothesis

open access: yesShui kexue jinzhan, 2012
A modification of Green-Ampt model is proposed based on the stratification hypothesis,which dynamically divided the soil column is into saturated layer,transient layer and dry layer.The model uses the concept of an equivalent hydraulic conductivity in ...

A comparison of discharge hydrograph using some methods of effective rainfall approach (case study: Upper Cisadane Watershed)

open access: yesJurnal Sumber Daya Air, 2016
Calculation of effective rainfall is an important step in hydrologic modelling. The used methods to calculate effective rainfall rarely observe watershed conditions on site.
