Land cover effects on soil infiltration capacity measured using plot scale rainfall simulation in steep tropical lowlands of Central Panama

Hydrological Processes, 2019
Understanding land use/land cover (LULC) effects on tropical soil infiltration is crucial for maximizing watershed scale hydro‐ecosystem services and informing land managers.

Land restoration by tree planting in the tropics and subtropics improves soil infiltration, but some critical gaps still hinder conclusive results

Forest Ecology and Management, 2019
Infiltration is one of the most important hydrological processes in ecosystems, having important influence on soil erosion control and runoff, soil moisture content and groundwater recharge.

Flux infiltration into soils: analytic solutions

Journal of Physics A: Mathematical and General, 1994
Summary: The Burgers model for flux infiltration into a semi-infinite soil is solved for generic space-dependent initial moisture and time dependent supply rate. General formulae in terms of quadratures are obtained for the moisture content and for the time to ponding of the soil.

Optimal discharge for closed-end border irrigation under soil infiltration variability

Agricultural Water Management, 2019
Traditional border irrigation designs have rarely considered that soil infiltration can vary. The design of border irrigation systems can be improved by the optimization of border irrigation discharge.

Effect of soil thickness on rainfall infiltration and runoff generation from karst hillslopes during rainstorms

European Journal of Soil Science, 2022
Knowledge of water movement from the hillslope critical zone is important for water management. However, the runoff process resulting from extreme rainfall events remains unclear due to rare field‐based natural monitoring data.

Infiltration Induced Soil Instabilities

Groundwater, 1970
ABSTRACT Theoretical analyses predicted and experimental observations—confirmed a mechanism by which strong capilary forces hindered instead of helped promote infiltration into soils. Infiltration into an unsaturated soil overlying an impermeable barrier displaces the air from the soil interstices.

Horizontal Infiltration into Layered Soils

Soil Science Society of America Journal, 1972
Abstract A numerical solution of the soil water movement equation is presented for horizontal infiltration into air‐dry layered soils. The solution is based upon a scaled soil water diffusivity function common to six homogeneous soils and values of the microscopic characteristic length ascertained for each soil from homogeneous ...

Water Infiltration Into Soils

1960
Publisher Summary Careful water management is essential to a stable and efficient agriculture, and efforts by a number of agencies are being directed toward water management and conservation activities, such as irrigation, drainage, flood prevention, and erosion control.

Effects of hillslope position on soil water infiltration and preferential flow in tropical forest in southwest China.

Journal of Environmental Management, 2021
The hillslope is an essential natural spatial gradient that influences hydrological processes by affecting water distribution, surface flow, soil erosion, and groundwater recharge.

Infiltration processes in cohesionless soils

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2012
AbstractIn this paper, a thermodynamically consistent four‐phase continuum model in the framework of the mixture theory is presented describing infiltration processes of suspensions in cohesionless granular material. The paper focuses on the distinct form of the constitutive relation for the volume production term of the fluidized particles and its ...
