A Novel Analytical Solution for Ponded Infiltration With Consideration of a Developing Saturated Zone

Water Resources Research, 2023
Ponding at the soil surface exerts profound impacts on infiltration. However, the effects of ponding depth on infiltration, especially the development of a saturated zone below the soil surface, have yet to be considered in present infiltration models. A

Analisis Volume Limpasan dengan Metode Green-Ampt

Jurnal Nasional Teknologi Terapan (JNTT), 2019
The development of modern era involves the economic, industrial and population growth and also increase of the social needs which cause the increase of the land needs. Land conversion which happens today has a negative impact on the environment and can damage the potency of the land use itself.

Can Flash Flood Risk Index Be an Early Warning Signal of Flash Floods in Ungauged Basin?

Journal of Flood Risk Management, Volume 19, Issue 1, March 2026.
ABSTRACT Flash flooding is amongst the most severe natural hazards, causing widespread socioeconomic impacts across both wet regions and drylands. In ungauged mountainous basins, effective risk warning based on hydrodynamic modelling is challenging due to sparse hydrological observations and complex terrain.

Effects of the Grain Size on Dynamic Capillary Pressure and the Modified Green–Ampt Model for Infiltration

Geofluids, 2018
Darcy-scale capillary pressure is traditionally assumed to be constant. By contrast, a considerable gap exists between the measured and equilibrium capillary pressures when the same moisture saturation is considered with a high flow rate, and this gap is

Building Treatment and Its Effects on City‐Scale Urban Flood Modeling

Journal of Flood Risk Management, Volume 19, Issue 1, March 2026.
ABSTRACT Physics‐based flood hydrodynamic models are widely used for predicting inundation in urban basins with complex building layouts. While the treatment of urban buildings in these models has been extensively discussed, over‐assumptions can introduce inaccuracies, uncertainties, and excessive computational effort, particularly under data‐scarce ...

Understanding Compound Pluvial–Fluvial Flood Hazards Under Climate Change: A Case Study of the Lower Tone River Basin, Japan

Hydrological Processes, Volume 40, Issue 2, February 2026.
A hindcast of Typhoon Hagibis inundation in the Lower Tone River Basin demonstrates reasonable consistency with observations. Scenario‐based simulations were performed to quantify flood hazards in this coastal watershed until the end of the twenty‐first century. Agricultural lands, most of which were reclaimed from lakebeds, face a greater flood hazard

Effect of Rainfall Intensity and Slope at the Beginning of Sandy Loam Soil Runoff using Rain Simulator (Case Study: Semnan City)

علوم آب و خاک, 2023
Runoff is formed by spending some time after rain and significantly depends on rainfall intensity, soil moisture, and slope. One of the fundamental questions about runoff is the time that it starts to create.

Evaluation of Infiltration Models with Double Ring Infiltrometer Test on Residual Soil in Kulonprogo, Indonesia

Civil Engineering Dimension
The hydraulic conductivity of soil is an essential parameter for evaluating the slope instability triggered by rain infiltration. This research uses a Double-Ring Infiltrometer (DRI) at five locations to estimate the hydraulic conductivity from a field ...

Two‐dimensional Green–Ampt response of high‐capacity tensiometers and a conceptual pathway to correct dynamic water retention curve data

Vadose Zone Journal, Volume 25, Issue 1, January/February 2026.
Abstract In the investigation of the relationship between measured soil suction and the rate of saturation change, an increase in response time prevents the tensiometer from instantaneously reacting to changes in suction. Solving this problem requires a tensiometer response model, which is based on the measured data from partial drainage and adsorption

Modeling of Infiltration from An Artificial Recharge Basin with a Decreasing Ponded Depth

Journal of King Saud University: Engineering Sciences, 1991
The first important physical process in basin recharge is the infiltration of water from the basin's bed to the water table below. The Green and Ampt approach was applied to model infiltration from an artificial recharge basin with a decreasing ponded ...
