Determination of Soil Behavior during Evaporation Using Geotechnical Datasets
نویسندگان
چکیده
Evaporation from soils is critical for agricultural water management. This requires a clear understanding of the retention and soil shrinkage behavior during escape due to fertilizers usage. Based on laboratory testing, this paper provides comprehensive dataset generated determination geotechnical properties inert silty sand active lean clay using distilled saline pore fluid under ambient conditions. The tests include fluid-independent general properties, fluid-dependent specific low-demand evaporation as baseline, high-demand capture summer.

Measuring evaporation from soil surfaces for environmental and geotechnical purposes
There are many reasons for the need to assess rates and quantities of evaporation or evapotranspiration from natural soil surfaces, the surfaces of deposits of mine or industrial waste, or soil-covered waste surfaces. These include assessing water balances for nearsurface soil strata, landfills, tailings dams and waste dumps and suitable deposition or application intervals for hydraulic fill ta...
متن کاملCalculation of humidity during evaporation from soil
The relative humidity at the surface of a soil is calculated as a function of time from a realistic, exactly solvable model for unsaturated fluid flow. When the evaporation rate is constant, as in the atmosphere-controlled phase, the surface relative humidity suddenly drops at a particular time, even though the humidity–time function is differentiable. This sudden transition still occurs, but i...
متن کاملEstimating Evaporation Coefficient during Two-stage Evaporation from Soil Surfaces
Evaporation coefficient (KE) is defined as the ratio of actual evaporation over potential evaporation under the same atmospheric conditions. The use of KE provides an alternative means for evaluating soil moisture status and quantifying soil evaporation by reducing in situ measurements. However, little effort has been made to evaluate the estimation of KE over soil surfaces. In this study, a re...
متن کاملDynamics of Soil Water Evaporation during Soil Drying: Laboratory Experiment and Numerical Analysis
Laboratory and numerical experiments were conducted to investigate the evolution of soil water evaporation during a continuous drying event. Simulated soil water contents and temperatures by the calibrated model well reproduced measured values at different depths. Results show that the evaporative drying process could be divided into three stages, beginning with a relatively high evaporation ra...
