Evaluation of potential erodibility of basin wetland using soil particles distribution

Abstract

Abstract:The objective of this study was to predict soil erodibility using soil properties of upper and lower tributary river (Enyong Creek and Ikpa river)

Erodibility Potential of a Sand Dredging Site in Rivers State, Nigeria

“…rainfall, runoff, streams and wind solely but coupled with dredging activity, sand erosion is determinable. Sand erosion is generally a three-step process of sand particles detachment, particles transportation or particles displacement and finally deposition at a different or new location [4]. Sand itself is a material with lesser degree of cohesion and therefore is vulnerable.…”

“…Also, sand organic matter (SOM) being highly discouraged due to heat in sand does not bind sand particles together into sticker aggregates, thereby offering no resistance to erosion. Permeability is the measure of the rate at which water percolates through sand under a head of water and is a function of sand structure, texture and bulk density, hence a function of sand particles [4]. Because of the high percolation feature of a sandy soil, erodibility is high hence erodibility can be defined by soil partcles size distribution.…”
