Impacts of an Internal Finer-Textured Layer on Soil Evaporation and Salt Distribution
Autor: Menggui Jin, Paul A. Ferre, Jingzhe He, Yanfeng Liu, Qian Liu
Publikováno v: Transport in Porous Media. 140:603-620
Previous investigations have demonstrated that an internal finer-textured soil layer will reduce the vertical water flow rate and increase water and solute storage in the vadose zone. However, most of them have been conducted under conditions of infi

We confirm that energy dissipation weighting provides the most accurate approach to determining the effective hydraulic conductivity (Keff) of a binary K grid. A deep learning algorithm (UNET) can infer Keff with extremely high accuracy (R2 >

Applying Simple Machine Learning Tools to Infer Streambed Flux from Subsurface Pressure and Temperature Observations
Autor: Paul A. Ferre, Kewei Chen, Mohammad A. Moghaddam, Xingyuan Chen, Xuehang Song, Glenn E. Hammond
We demonstrate the application of two simple machine learning tools - regression tree and gradient boosting analyses - to a hydrologic inference problem to address two objectives. The first goal wa...

We used the weighted wavelet method to perform spectral analysis of observed long-term precipitation, streamflow, actual evapotranspiration, and soil water storage at a sub-humid mountain catchment near Tucson, Arizona, USA. Fractal scaling in precip

Practical limitations and applications of short dead time surface NMR
Autor: A. C. Hinnell, David O. Walsh, Peter Turner, Paul A. Ferre, Elliot Grunewald
Publikováno v: Near Surface Geophysics. 9:103-113
There is increasing interest in the unique measurement capabilities of nuclear magnetic resonance (NMR) for hydrologic applications. In particular, the ability to quantify water content (both bound and free) and to infer the permeability distribution
