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

3DMGAR: A Transient Quasi-3D Point-Source Green–Ampt Infiltration and Redistribution Model

Vadose Zone Journal, 2018
Although Richards’ equation (RE) generally provides a good description of infiltration and water redistribution in soils, its numerical solutions can be computationally intensive or suffer from numerical instability and require extensive soil data ...

Effects of Wildfire on Soil Hydraulic Properties in the Western Oregon Cascades

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract Wildfires can substantially impact the hydrology of forested watersheds, increasing the risk of hydrologic hazards such as flash floods and debris flows. Soil hydraulic properties related to infiltration are a key control in determining the timing and magnitude of these hydrogeomorphic events.

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

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.

Harnessing Community Science to Address Flood Risks and Build Climate Resilience With Nature‐Based Solutions (NbS)—A Case Study From the Quad Cities Region

Community Science, Volume 5, Issue 1, March 2026.
Abstract Urban regions situated along major river systems are increasingly facing flood risks, driven by the combined effects of rapid urbanization and intensifying climate change. The Quad Cities region, comprising Davenport and Bettendorf in Iowa, and Rock Island, Moline, and East Moline in Illinois, is vulnerable to flood hazards caused by extreme ...

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 ...

Midwives' Perception Towards Male Partners' Involvement in Labour Companionship: A Qualitative Study

Journal of Advanced Nursing, Volume 82, Issue 3, Page 2307-2319, March 2026.
ABSTRACT Background Labour companionship is a recommendation by WHO that health authorities enable women to choose a companion during labour to ensure a safe and dignified labour experience for the birthing woman. However, most healthcare facilities in low‐ and middle‐income countries do not necessarily consider this maternal need, which hampers a ...

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.
