    Satellite soil moisture estimates have received increasing attention over the past decade. This paper examines the applicability of estimating soil moisture states and soil hydraulic parameters through two...

  2. Combined Assimilation of Streamflow and Satellite Soil Moisture with the Particle Filter and Geostatistical Modeling

    Assimilation of satellite soil moisture and streamflow data into a distributed hydrologic model has received increasing attention over the past few years. This study provides a detailed analysis of the joint...

  3. Geotechnical Statistical Evaluation of Lahore Site Data and Deep Excavation Design

    Geotechnical characterization for foundation design is critical during preliminary planning, designing and feasibility studies of various engineering projects. In this research, an effort has been made to...

  4. Evaluating Global Sensitivity Analysis Methods for Hydrologic Modeling over the Columbia River Basin

    Global Sensitivity Analysis (GSA) approach helps to identify the effectiveness of model parameters or inputs and thus provides essential information about the model performance. The effects of 14 parameters and...

  5. Geostatistical Examination of the Geotechnical Portland BES Databases with Emphasis on Silt

    Willamette Valley silt deposits from historical catastrophic flood events present a difficult problem for subsurface engineers practicing in the Portland, Oregon area. Silts exhibit behavior of two very...

  6. Key Aspects for LRFD Implementation of Driven Pile Capacity by Dynamic Methods

    Inputs and interpretation procedures for pile wave equation analysis, which correlates measured field dynamic driving response to axial pile static capacity, are highly dependent on site-specific soil...

  7. Parametric Study of Rocking Shallow Foundations under Seismic Excitation

    Conventional design of structures relies on incorporating a certain level of inelastic deformation into select components to provide seismic energy dissipation, while ensuring the foundation remains relatively...

  8. Remote Sensing of Drought: Vegetation, Soil Moisture, and Data Assimilation

    Application of remote sensing is emerging for operational drought monitoring and early warning as it offers opportunities for assessing drought from different perspectives. This chapter provides an overview of...

  9. Transport of Heat Activated Persulfate and Its Application for In-situ Chemical Oxidation of Residual Trichloroethylene

    In situ chemical oxidation is a promising technology for the remediation of persistent subsurface contamination. Increasingly, the persulfate ion is being studied for use in these systems, both on its own as a...

  10. Detecting Non-Stationary Hydrologic Model Parameters in a Paired Catchment

    Non-stationarity represents one of the major challenges facing hydrologists. There exists a need to develop modelling systems that are capable of accounting for potential catchment changes, in order to provide...
