The influence of antecedent moisture content (AMC) on infiltration into water repellent soil: Laboratory experiments and model calculations Open
The sensitivity of infiltration rate to antecedent moisture content (AMC) in wettable soils is well-established with a low AMC promoting a higher initial infiltration rate. For water repellent soils, such as those found on fire-affected la…

Hydrograph and recession flows simulations using deep learning: Watershed uniqueness and objective functions Open
This study examines streamflow simulations using deep learning (DL) to understand the information extraction capability of global DL models trained on multiple watersheds. The study separately examined the entire streamflow time series and…

Fire effects on soil structure and hydraulic conductivity Open
Fire-induced changes in soil structure and hydraulic conductivity reduce infiltration and increase the likelihood for post-fire flooding and debris flows. Current post-fire hydrology models, however, cannot take fire-induced soil structure…

Is there Information in Residuals: Hydrograph and Recession Flows Predictions using Deep Learning? Open
This study examines streamflow simulations using deep learning (DL) to: (1) Understand why global DL models trained on multiple watersheds outperform local DL models trained on single watersheds, given the watershed uniqueness hypothesis a…

Changes in streamflow statistical structure across the United States due to recent climate change Open
Changes in statistical structure (spectral properties) of streamflow across the USA due to climate change were studied for water years 1980–2013. The Fractionally differenced Autoregressive Integrated Moving Average (FARIMA) model was fit …

Towards mechanistic representation of wildfire effects on soil – downscaling to quantify subsurface heat fluxes Open
Advances in wildfire modeling have focused on refining atmospheric interactions for obvious links between local airflows, combustion dynamics, fire line advance and smoke plume transport. Yet, lasting impacts of wildfires on landscapes are…

Changes in Streamflow Statistical Structure across the United States due to Recent Climate Change Open
A variety of watershed responses to climate change are expected due to non-linear interactions between various hydrologic processes acting at different timescales that are modulated by watershed properties. Changes in statistical structure…

Keynote: Global Trade, Borders, and Technology Open
Borders demarcate boundaries between regions and serve two, often competing, goals: Facilitating the efficient trade of goods, services, and passage of individuals with minimal friction; and enforcing the policies and regulations of each r…

Markov Models and the Ensemble Kalman Filter for Estimation of Sorption Rates Open
Non-equilibrium sorption of contaminants in ground water systems is examined from the perspective of sorption rate estimation. A previously developed Markov transition probability model for solute transport is used in conjunction with a ne…
