A proposed method for estimating interception from near-surface soil moisture response

Estimating Soil Moisture Profile Dynamics from Near-surface Soil Moisture Measurements and Standard Meteorological Data

Estimating Surface Soil Moisture Using Radarsat-2

Extremes in soil moisture, either too much or too little, present a significant risk to agricultural productivity. Managing and mitigating risk requires information and knowledge to assess risk potential, implement risk reduction strategies and deliver responses to this risk. Synthetic aperture radars (SARs) are sensitive to the dielectric properties of soils and are thus well suited to provide...

An Overview of the “Triangle Method” for Estimating Surface Evapotranspiration and Soil Moisture from Satellite Imagery

An overview of the ‘triangle’ method for estimating soil surface wetness and evapotranspiration fraction from satellite imagery is presented here. The method is insensitive to initial atmospheric and surface conditions, net radiation and atmospheric correction, yet can yield accuracies comparable to other methods. We describe the method first from the standpoint of the how the triangle is obser...

Inverse Method for Estimating the Spatial Variability of Soil Particle Size Distribution from Observed Soil Moisture

Soil particle size distribution PSD i.e., clay, silt, sand, and rock contents information is one of critical factors for understanding water cycle since it affects almost all of water cycle processes, e.g., drainage, runoff, soil moisture, evaporation, and evapotranspiration. With information about soil PSD, we can estimate almost all soil hydraulic properties e.g., saturated soil moisture, fie...

Modelling near-surface soil temperature and moisture for germination response predictions of post-wildfire seedbeds

A major contributor to degradation on rangelands in the western United States is the expansion of undesirable annual weeds following wildfire or other disturbance. The Simultaneous Heat and Water (SHAW) model was applied to three soil types (loamy sand, sandy loam, and silt loam) to simulate near-surface soil temperature and water for predicting potential seed germination in post-wildfire reveg...
