Prediction of soil characteristics over large areas is desirable for environmental modeling. In arid environments, soil characteristics often show strong ecological connectivity with natural vegetation, specifically biomass and/or canopy cover, suggesting that the soil characteristics may be predicted from vegetation data. The objective of this study was to predict soil infiltration characteris...

Interlocking concrete block pavements (ICBPs) have been widely used in car parks to reduce runoff. Researches have demonstrated that clogging is the most influential factor in the reduction of the infiltration capacity of this type of permeable pavement. Nevertheless, there is no laboratory study of the infiltration performance of ICBPs that combines clogging levels with variables related with ...

The benefits of using permeable interlocking concrete pavement systems (PICPs) have not translated into widespread adoption in Australia, where their uptake has been slow. This paper communicates the actual performance PICPs installed field by providing evidence long-term efficiency. There are currently no Australian standards for design, specification and installation PICPs. In this study, mea...

Bjorneberg, USDA-ARS, Northwest Irrigation and Soils Research Lab., 3793 N. 3600 E., Kimberly, ID 83341 USA. *Corresponding author: [email protected] ABSTRACT For surface irrigation, the rate and spatial characteristics of infiltration processes influence crop productivity, water use efficiency, and erosion potential of stream flows. A change in infiltration rate a...

Hydrological modeling of the unsaturated soil zone fluxes allows the transfer processes simulation through the hydrological active soil zone. The pedotransfer functions (FTP) are useful tools in the modeling process. They contain analytical functions derived through statistic optimization process using a large amount of soil information data. This paper aims to analyze the level of reliability ...

Woodland planting is gaining momentum as a potential method of natural flood management (NFM), due to its ability break up soil and increase infiltration water storage. In this study, 2.2 km2 area in Warwickshire, England, planted with woodland every year from 2006 2012, was sampled using Mini Disk infiltrometer (MDI). Infiltration measurements were taken 10 200 cm away the trees, November 2019...

Urbanisation and the replacement of previously vegetated areas with impermeable surfaces reduces lag times overland flow increases peak flows to receiving watercourses; magnitude this will increase as a result climate change. Tree planting is gaining momentum potential method natural flood management (NFM) due its ability break up soil infiltration water storage. In study, 2.2 km2 clay-textured...

Superabsorbent polymers (hydrogels) have been studied for their ability to influence soil hydraulic conductivity because they can store and release water due swelling properties. However, concerns related the increased use of synthetic hydrogels necessitates a switch bio-based hydrogels, which are renewable more biodegradable in comparison hydrogels. In this study, we synthesized lignin-based h...

Evidence from experimental and established grasslands indicates that plant biodiversity can modify the water cycle. One suspected mechanism behind this is a higher infiltration capacity (νB) hydraulic conductivity (K) of soil on species-rich grasslands. However, in agriculturally managed grasslands, effects cannot be studied independent land-use effects. Therefore, we investigated grassland sys...
