A mechanistic approach to topsoil damage due to slip of tractor tyres

Lyesse Laloui, Andrea Battiato, Etienne Diserens

Tractor traction tyres interact with soil by a system of normal and tangential stresses along the soil-tyre contact surface. In this interaction both soil and tyre deform according to their own stress-strain relationships. Soil deformation results in the f ...

Depletion of Stem Water of Sclerocarya birrea Agroforestry Tree Precedes Start of Rainy Season in West African Sudanian Zone

Marc Parlange, Natalie Claire Ceperley, Theophile Mande

Understanding water use by agroforestry trees in dry-land ecosystems is essential for improving water management. Agroforestry trees are valued and promoted for many of their ecologic and economic beneﬁts but are often criticized as competing for valuable ...

Impacts of irrigation with industrial treated wastewater on soil properties

André Mermoud, Pascal Boivin

Wastewater reuse in agriculture is a widespread practice in developing countries, especially in urban areas where water shortage and poverty encourage people to use that marginal resource. Raw or treated wastewaters are used by farmers, but even treated wa ...

Effect of Antecedent Conditions on Soil Erosion Dynamics in a Laboratory Flume

David Andrew Barry, Alessandro Brovelli, Seifeddine Jomaa

The effect of antecedent conditions on precipitation-driven soil erosion dynamics through multiple rainfall events was investigated using a pair of 6-m • 1-m flumes with 2.2% slope. Three experiments denoted H6, H7-E2 and H7-E3, involved the same precipita ...

Soil erosion and effluent particle size distribution under different initial conditions and rock fragment coverage

David Andrew Barry, Alessandro Brovelli, Seifeddine Jomaa

It is well known that the presence of rock fragments on the soil surface and the soil’s initial characteristics (moisture content, surface roughness, bulk density, etc.) are key factors influencing soil erosion dynamics and sediment delivery. In addition, ...

Laboratory flume experiments to study the influence of initial conditions and rock fragment cover on soil erosion dynamics

David Andrew Barry, Alessandro Brovelli, Seifeddine Jomaa

The influence of the initial soil surface characteristics and rock fragment coverage on precipitation-driven soil erosion was investigated through laboratory experiments on a 6-m × 1-m soil parcel with mild slope. A sequence of four experiments, consisting ...

Influence of rock fragment coverage on soil erosion and hydrological response: Laboratory flume experiments and modeling

David Andrew Barry, Alessandro Brovelli, Seifeddine Jomaa

Two laboratory flume experiments on the effect of surface rock fragments on precipitation-driven soil erosion yields were carried out. The total sediment concentration, the concentration of seven individual size classes and the flow discharge were measured ...

Heated Optical Fiber for Distributed Soil-Moisture Measurements: A Lysimeter Experiment

Marc Parlange, Ivan Lunati, Nicolaas Cornelis van de Giesen, Francesco Ciocca

An Actively Heated Fiber Optics (AHFO) method to estimate soil moisture is tested and the analysis technique improved on. The measurements were performed in a lysimeter uniformly packed with loam soil with variable water content profi les. In the fi rst me ...

Soil erosion transport through multiple rainfall events in the presence of stone cover: Laboratory flume experiments and analysis with the Hairsine-Rose model

David Andrew Barry, Alessandro Brovelli, Seifeddine Jomaa

Soil erosion is a major environmental problem that can lead to loss of fertility and degradation of agricultural fields. In order to develop efficient strategies to mitigate the impact of precipitation and reduce the erosion rate, a process-based understan ...
