Predicting event soil loss from bare plots at two Italian sites

Predicting event soil loss from bare plots at two Italian sites
Including runoff in USLE-type empirical models is expected to improve plot soil loss prediction at the event temporal scale. The goal of this paper was to develop an estimating procedure of event soil loss from bare plots at 2 Italian sites, i.e

Using palm-mat geotextiles for soil conservation : II. Effects on in situ soil particle size distribution and nutrient concentration

, with duplicate treatments :(1) bare soil; (2) permanent grass; (3) bare soil with 1 m Borassus-mat buffer zones at the lower end of the plots; (4) bare soil with 1 m Buriti-mat buffer zones at the lower end of the plots; and (5) completely-covered with Borassus

Bio-geomorphic effects on tidal channel evolution : impact of vegetation establishment and tidal prism change

density and channel width) change as (1) vegetation establishes on an initially bare intertidal platform and (2) sediment accretion on the intertidal platform leads to a reduction in the tidal prism (i.e. water volume that during a tidal cycle floods
to and drains back from the intertidal platform). Based on a time series of aerial photographs and digital elevation models, the AA. derived the channel geometric properties at different time steps during the evolution from an initially low-elevated bare tidal

Effects of interrill erosion, soil crusting and soil aggregate breakdown on in situ CO2 effluxes

A set of rainfall simulations were carried out on bare loess-burden soil with different antecedent soil moisture content. All treatments were compared with controls protected from rain drop impact using a fine-meshed geotextile. As expected, runoff
and sediment delivery was significantly larger on bare compared to covered soils, while surface runoff and sediment delivery increased (in most cases) with rising antecedent soil moisture as well as rainfall duration. Crust thickness increased with antecedent

Soil water repellency in rangelands of Extremadura (Spain) and its relationship with land management

cover, water repellency was highest at sites covered by holm oak litter. At soil surfaces covered by cork oak litter, dry grass and mosses the degree of repellency was lower. Almost all sites with a bare soil surface were hydrophilic. A significant
positive relationship between livestock density and the degree of bare soil existed, and consequently, areas with high animal numbers were dominantly hydrophilic. No significant relationships were encountered between the degree of soil water repellency

Herbicide transport via surface runoff during intermittent artificial rainfall : A laboratory plot scale study

Herbicide losses and the influence of physicochemical properties of flufenacet, metazachlor and terbuthylazine were studied on a microplot of bare soil and slight slope with rainfall simulation. The highest concentrations were detected in the first

Shared space and the post-politics of environmental change

This article analyses the shared space and the post-politics of environmental change through the example of vision-impaired people in London. It shows that their diverse needs are barely recognised or given a platform to influence shared space

Effects of rainfall intensity, underlying surface and slope gradient on soil infiltration under simulated rainfall experiments

angle) on the soil moisture increase after rainfall and the infiltration recharge coefficient (IRC). Soils hosting 3 different plants (purple medic, PM; spring wheat, SW; and ryegrass, RS) were considered, along with bare soil (BL). These soil surfaces
were tested with 4 different slopes and subjected to 5 different rainfall intensities. It is showed that : Vegetation cover yields a greater soil moisture increase than do bare land; Water storage initially grows and then reduces as the rain intensity

Badlands denudation hot spots : The role of parent material properties on geomorphic processes in 20-years monitored sites of Southern Tuscany (Italy)

This paper shows the results of grain size, geochemical and mineralogical composition of parent materials from Upper Orcia Valley sites (Southern Tuscany), to further elucidate the role of their properties on processes acting on both bare

Age and hydrological significance of lichen limits on sandstone river channels near Sydney, Australia

Trimmed lichen communities (lichen limits) are abrupt changes from a lichen community to a scoured bare rock surface and have been used to determine bankfull channel capacity on bedrock channels and their response to the combined disturbances
