Evaluation of infiltration and rainfall-runoff attributes by utilizing a rainfall simulator

INTERNATIONAL JOURNAL OF AGRICULTURAL SCIENCES, 2023
The impact of different land management practices on the amount of runoff and infiltration was studied in a laboratory for a period from August to December (2018) by simulating the natural conditions. Special trays were designed to hold a unique soil surface cover and rain was artificially poured onto them from a pre-determined height using a rainfall ...

Three modes of rainfall infiltration inducing loess landslide

Natural Hazards, 2015
Rainfall infiltration depth in an integrated and homogeneous soil mass is extremely limited. How does rainfall infiltrate into a loess slope developed with various fractures and holes? How do infiltration mechanisms impact slope stability?

Estimating infiltration for erratic rainfall

Water Resources Research, 1975
To estimate cheaply the infiltration/runoff of typically unsteady rainfall events for purposes of watershed modeling, a method known as ‘time compression’ has been tested against hysteretic Darcy computations. This method assumes that for a given soil the maximum infiltration rate is simply a function of the cumulative infiltration, regardless of the ...

Rainfall infiltration into bare soils

Water Resources Research, 1977
Raindrop impact destroys the surface aggregates of soils and gradually forms a continuous crust. Infiltration rates of bare soils are determined by this process. A theoretical model presented previously was tested under field conditions with a sandy loam soil.

Experimental rainfall–runoff data: Reconsidering the concept of infiltration capacity

Journal of Hydrology, 2011
Many infiltration models rely on an effective hydraulic conductivity parameter (Ke) which is often determined in the field from rainfall simulation experiments on small plots.

Bifurcation analysis of rainfall infiltration

Water Resources Research, 1981
The understanding of local characteristics within the global behavior of catchment dynamics is an important concern to both theorists and field hydrologists. The law of averages, when applied to local infiltration behavior, often fails to render representative information as to the nonlinear response of a catchment due to runoff thresholds, feedback ...

A rainfall simulator study of infiltration into arable soils

Agricultural Water Management, 1992
Since Hortonian surface runoff is one possible mechanism for the fast transport of agricultural chemicals from arable soils to surface water, more information is needed on its significance in agricultural areas. The present study concerns the sandy soils of the Dutch Cover Sands area, and is based on the approximate one-dimensional Mein-Larson ...

Constant-rainfall infiltration

Journal of Hydrology, 1980
Abstract An approximate solution of the infiltration equation for rain of constant intensity is developed. From the theory, the ponding time and the development of the moisture profile at time shorter than ponding time are determined. Using the theoretical background, simple empirical and algebraic equations are derived for the calculation of the ...

Microrelief, rainfall and cover effects on infiltration

Soil and Tillage Research, 1990
Abstract Field infiltration behavior of a fine loamy mixed mesic, Typic Haplaquoll, was related to indices of surface microrelief and rainfall energy using simulated rainfall and ponded water. Infiltration of simulated rainfall was controlled primarily by a surface crust.
