Indonesia has 129 active volcanoes; therefore, the volcanic-related disasters risk is relatively high. Lahar flood is a secondary post-eruption disaster, which is triggered by the rainfall due to the movement of volcanic material by the runoff. After the

A green-Ampt model considering unsaturated zone and pore air pressure
The relationship between infiltration time and the depth of the wetting front can be solved using Darcy’s law. According to this, the infiltration rate is equal to the derivative of the infiltration amount regarding time.

The rainfall infiltration analysis of slopes is of a great significance to the reinforcement design, mitigation and risk mitigation of rainfall-induced landslides. The classical Green-Ampt model, whose parameters have clear physical meanings and which is

Establishing a reasonable rainfall infiltration model is an important prerequisite for revealing the rainfall-induced slope failure mechanism and disaster prevention and control. The traditional Green-Ampt model does not consider the distribution of soil

Abstract This study investigates rainfall runoff behavior of five major torrential Nullahs' of Dera Ghazi Khan (D. G. Khan) for flash flood events. The integration, and fusion of satellite‐based meteorological, topographical, and pedo‐transferred function's (PTF) derived soil hydraulic datasets at 250 m grid size substantially proves a viable approach ...

Rapid Hydraulic Modelling in Post‐Wildfire Channels Using a Tiered Framework
A three‐tier hydraulic modelling framework enables rapid, safe calibration of post‐wildfire channel models using remote sensing and limited field data. Tested on two contrasting burned Colorado watersheds, discharge and salt tracer velocity measurements alone captured most of the achievable model accuracy, with detailed bathymetric survey adding little

Many mechanisms can lead to successful plant invasion, but their importance is often context dependent. One such mechanism is allelopathy: chemical inhibition of neighbouring plants. The importance of allelopathy may be mediated by soil microbiota and environmental conditions, and depend upon the species or functional group affected.

A Novel Approach to Characterize and Model Drywell Infiltration Capacity
Abstract Drywells are vadose‐zone wells constructed for infiltration and recharge, typically positioned far above the water table. They provide for efficient infiltration, with high infiltration rates per land area, because the infiltration process is below the land surface.

Border Irrigation Modeling with the Barré de Saint-Venant and Green and Ampt Equations
In gravity irrigation, how water is distributed in the soil profile makes it necessary to study and develop methodologies to model the process of water infiltration and redistribution.
