Effects of biochar nanoparticles as a soil amendment on the structure and hydraulic characteristics of a sandy loam soil

Soil use and management, 2021
Biochar as a soil amendment can influence the physical and solute transport properties of soils and, thus, provide a means to improve soil fertility. However, the use of different sized biochar particles down to the nano‐scale has revealed inconsistent ...

LNAPL Retention in Sandy Soil

Groundwater, 1993
Abstract The vertical distribution of free and residual aviation gasoline, a light nonaqueous phase liquid (LNAPL), through the capillary fringe of a uniform, medium sand is measured and used to calibrate an existing model. The total saturation profile is governed by a classical moisture retention characteristic, with the matric ...

An extreme machine learning model for geosynthetic-reinforced sandy soil foundations

, 2020
In the past, several experimental and theoretical studies have been carried out to evaluate the ultimate bearing capacity (UBC) of geosynthetic-reinforced sandy soil foundations (GRSSFs).

Instability Behaviour for Sandy Soils

Geo-Frontiers 2011, 2011
The concept of collapse line, CL, or instability line, IL have been reported in literature for analysing instability behaviour of sands under undrained shearing. The similarity, but different implications of these two concepts sometimes led to some confusion.

The impact of pyrolysis conditions on orange peel biochar physicochemical properties for sandy soil

Waste Management Research, 2020
The citrus industry is considered one of the main contributors to agricultural waste. Peels are commonly used in the food industry or as feedstock in biorefining.

Microbially Induced Calcite Precipitation for Seepage Control in Sandy Soil

Geomicrobiology Journal, 2019
Microbially induced calcite precipitation (MICP) can reduce the permeability of soil by reducing the pore volumes. A MICP-based soil improvement method to control water leakage in irrigation channels and reservoirs built on sandy soil grounds is ...

Hydraulic Conductivity Prediction for Sandy Soils

Groundwater, 2004
Abstract The potential for petroleum‐contaminated soils to impact ground water is evaluated using the soil leachability model in South Carolina and Georgia. In this model, the Green and Ampt (1911) equation is used to estimate unsat‐urated flow with saturated hydraulic conductivity (

Phosphorus Leaching from Biosolids‐Amended Sandy Soils

Journal of Environmental Quality, 2002
ABSTRACTIncreasing emphasis on phosphorus (P)‐based nutrient management underscores the need to understand P behavior in soils amended with biosolids and manures. Laboratory and greenhouse column studies characterized P forms and leachability of eight biosolids products, chicken manure (CM), and commercial fertilizer (triple superphosphate, TSP ...

Electrical resistivity of sandy soil

Géotechnique Letters, 2015
This paper presents the results of an investigation into the interaction between the various electrical factors pertaining to resistivity tests in Perth sandy soil (specifically AC input voltage and frequency) and those controlling the soil characteristics, specifically water content and relative density of the soil, and the type of water employed in ...

Modeling of compressive strength of cemented sandy soil

Journal of Adhesion Science and Technology, 2019
This paper attempted to show the application of particle swarm optimization in the prediction of the compressive strength of cement sandy soil from the curing period, porosity of sample and percentage of cement.
