The soils of Gadas, object the present study, are identified on macromorphological, physico-chemical level and indices erodibility related to their properties. analyzes were carried out by standard methods. macromorphological analysis a toposequence made it possible identify five types soils: lithosols which occupy high zones landscape, colluvial (arenosols, regosols) located piedmont, alluvial...

Introduction and Methods Cohesive sediments in marine and coastal environments are responsible for degrading water quality, influencing the cycling and availability of particle bound contaminants, and infilling navigable waterways. In spite of their significance to coastal environments, there are still major gaps in our understanding of many of the fundamental processes governing cohesive sedim...

Soil Erosion is the detachment, transportation and deposition of soil sediment from one place to another. This has led loss lives infrastructure in many parts Nigeria. properties play a role it vulnerability extent erosion. study aims evaluate selected physical as they interact cause erosion area. The was conducted 2012 gully site relation its potential erodibility channel. done by collection v...

Middle and southern Iraq suffers from polluted soils due to crude oil, spilled on land, leakage from transmitting pipe networks, or petroleum products from refineries. Many researchers have studied pollution impacts on the soil in details, but there is a clear lack of investigation on the influence of crude oil on soil erodibility. Recent researches have investigated the influence of pollution ...

Acid soil covers one third of the world arable lands. Excess Al and H in acid soil are not favorable for most plants. Calcium carbonates and gypsum (CaSO4) are used to improve chemical status of the acid soil. However, application of Ca cation may sometimes enhance dispersion and deteriorate soil physical properties. Presenting study discusses effect of non-ionic polyacrylamide (PAM) applicatio...

The overall goal of this research is to compare the effects of woody and herbaceous vegetation on stream bank erosion. This chapter presents the third of three substudies that address the impact of vegetation on stream bank erosion. The goal of this study was to determine the erodibility of rooted stream bank soils and to evaluate the relative effects of vegetation type, root density, and freez...
