Study on the cumulative effect of drip irrigation on the stability of loess slopes

Geomatics, Natural Hazards & Risk
Infiltration of irrigation water is an important factor affecting the stability of loess slopes. In this study, based on the Green-Ampt infiltration model.

Modeliranje dinamike pražnjenja kišnih vrtova primjenom Green-Ampt modela

Zbornik Radova
U radu je prikazan relativno jednostavan proračunski postupak za modeliranje dinamike pražnjenja kišnih vrtova, odnosno adekvatno dizajniranih infiltracijskih površina koje se u urbaniziranim sredinama koriste za privremeno zadržavanje oborinske vode.

Application of Green-Ampt Equation to Long Term Runoff Analysis.

Journal of Japan Society of Hydrology and Water Resources, 1996
本研究ではGreen-Ampt式を長期間流出解析に適用し,タンクモデルに準じた概念モデルを提案した.このモデルでは,無降雨期の土壌水分の再配分を単純なプロファイルで表すことによって,連続的に浸入現象を追跡することができた.また,土壌深さが有限の場合について,任意降雨強度条件下での浸入強度の計算手順も提示した.そして,本モデルを用いて,二つの試験流域の流出解析を行い,比較的良好な再現性を得た.なお,幾つかのパラメータについて,同定した値と現地採土した土壌からの実測値との比較を行った結果,両者の間にある程度の整合性があることが示された.

Comparative Performance of SCS-CN and Green-Ampt Methods in HEC-HMS Under Spatio-Temporal Rainfall Variability in a Semi-Arid Mexican Basin

Hydrology
Pronounced spatio-temporal variability of rainfall in semi-arid basins remains a central challenge for rainfall–infiltration–runoff modeling, particularly in ungauged or newly instrumented catchments where continuous soil-moisture data are unavailable ...

Feasibility Investigation of Improving the Modified Green–Ampt Model for Treatment of Horizontal Infiltration in Soil

, 2019
Water infiltration in soil is a complex process that still requires appreciation of interactions among three phases (soil particles, water and air) to enable accurate estimation of water transport rates. To simulate this process, the Green–Ampt (GA)

Equação de green-ampt para a infiltração da água no solo aproximações numéricas para explicitação do volume infiltrado Green-ampt equation for water infiltration into soil numerical approximations to the explicit formulation for the accumulated water

Revista de Ciências Agrárias, 2008
O modelo de infiltração de Green-Ampt (1911), muito utilizado ainda hoje em Hidrologia, não permite explicitar de forma exacta o volume acumulado por infiltração em função do tempo.

Using the Green and Ampt infiltration equation on native and plowed rangeland soils

, 1988
Soil textural relationships were used on 3 soil series on both plowed and native rangeland to predict Green and Ampt infiltration equation parameters. Infiltration rates predicted from the Green and Ampt soil texture relationships were regressed against ...

Modeling Water Infiltration in Rain Gardens Using the Green-Ampt Model

Cilj rada je prikazati jednostavan proračunski postupak za modeliranje pražnjenja kišnih vrtova, koji su zamjenski pristup odvodnji oborinskih voda u urbaniziranim sredinama jer privremeno zadržavaju oborinu i uz sporu infiltraciju je upuštaju u tlo.
