Site-Specific Erodibility in Claypan Soils: Dependence on Subsoil Characteristics

Erodibility and infiltration characteristics of five major soils of southwest Spain

Equations used to calculate erodibility in the Water Erosion Prediction Project soil erosion Ž . model WEPP are based on erodibility studies in the USA and may not function well in another Ž . region. This study was conducted to: i analyze erodibility and infiltration characteristics of some Ž . predominant soils of southern Spain, and ii test equations used to calculate interrill erodibility i...

Measuring Erodibility of Cohesive Soils Using Laboratory Submerged Jet Test

Shigella flexneri causes a severe form of bacillary dysentery characterized by cramping, diarrhea, and fever. S. flexneri uses a type three seceretion system (TTSS) to invade the colonic epithelium by injecting effector proteins directly into the host cell cytoplasm. The TTSS consists of a basal body, spanning both the outer and inner membranes, and a surface exposed needle. After the proper en...

Spatial Characteristics of Claypan Soil Properties in an Agricultural Field

Spatial variability in soil properties has long been observed within uniformly managed fields. Understanding the spatial characteristics of soil properties would be helpful in understanding soil–landscape relationships and in the development of site-specific management. The primary objective of this research was to quantify the spatial characteristics of claypan soil properties for a 4-ha agric...

Relation between swelling and erodibility of cohesive soils

Subsoil Water

In March, last, Drs. Cunningham and Lewis put ia motion experiments to test the value of Professor Pettenkofer's theory of the propagation of cholera, in the neighbourhood of Calcutta, by daily measurements of the level of subsoil water: they a^s0 caused similar experiments to be undertaken in Oudh. The measurements are now ordered by the Government of India to be carried out in every military ...
