Abstract Understanding how climate change alters hydrological connectivity and associated nitrate dynamics remains a key challenge in lowland, mixed land‐use catchments. Here, we use a tracer‐aided, fully distributed ecohydrological modeling framework to investigate how future climate conditions may influence water fluxes and nitrate dynamics in such ...

Abstract Extreme rainfall‐triggered landslide–flash flood–debris flow hazard chains (LFFDF) are increasingly responsible for hydroclimatic losses worldwide. Although dynamics of individual hazards are established, transition mechanisms within LFFDF governed by coupled landslide–channel responses remain unresolved.

Ponding Analysis with Green-and-Ampt Infiltration [PDF]
The ponding of water over level terrain caused by storms of arbitrary temporal intensity is quantified by solving water-balance differential equations involving cumulative rainfall, infiltration, the depth of ponded water, and evaporation of ponded water.

Rapid Infiltration Signatures From Global Infiltration Observations
Abstract Rapid infiltration influences rainfall partitioning, subsurface water movement, and freshwater availability, yet its large‐scale spatial organization remains poorly constrained by limited observations and the lack of scalable approaches for synthesizing infiltration measurements.

The Impact of Model Resolution on the Water Balance of a Dryland Basin
Dryland regions are poorly represented in large‐scale hydrological models. The spatial and temporal resolution of these models strongly influences model performance and affects the partitioning of precipitation into hydrological fluxes and storage changes.

Evaluación de infiltración con equipo TDR-300 y el modelo Green y Ampt, en suelo con aditivos orgánicos en Guasave, Sinaloa, México [PDF]
The water needs in crops are naturally satisfied by rains, when it is insufficient, gravity irrigation is applied, which requires knowing the soil’s moisture behavior.

Application of Isotopic Information for Estimation of Parameters in Green-Ampt Infiltration Model
:Aiming at the deficiency of hydrological information in the estimation of parameters in hydrological models, based on the combination of Green-Ampt infiltration model and isotopic mixing model, parameters were estimated in Green-Ampt infiltration using ...

Increasing urban flash flood risk attributable to both climate and development
A new event impact attribution methodology that combines convection‐permitting climate model data with flood inundation modelling was used for a five‐hour flash‐flooding event in the suburbs of Leeds in 2014. The results show increased urban flood extent due to both climate change (+16%) and increased urbanisation (+29%).

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.
