Ecological flow regime, heat fluxes and thermal response

    An important problem in scientific hydrology and heat transfer is accounting for scale-dependent heterogeneity that governs heat and water exchange in large river basins.

    My dissertation research considers:

    Part 1: Longitudinal heterogeneity of flow and heat fluxes in a large lowland river: A study of the San Joaquin River, CA, USA during a large-scale flow experiment

    Part 2: Meander-bend scale influence of hyporheic flow, geomorphology, and heat fluxes on temperature in a large lowland river

    This study is located on a 60-kilometer mainstem reach of the San Joaquin River California, USA. The San Joaquin River Restoration Program has defined this reach as "Reach 1" of a 148-mile restoration planning area. Reach 1 begins at Friant Dam (River Mile 267.5) and ends at Gravelly Ford (River Mile 229), the historical transition between gravel- and sand-bedded reaches.

Nutrient Trading/Watershed Modeling in the Ohio River Basin

  • Goal: to support a new regional Water Quality Trading (WQT) pilot program in select watersheds of the Ohio River Basin.
    • Current work aims to develop a watershed model using USEPA's BASINS 4.0 framework and WARMF model version 6.2. (Advisor: Arturo Keller)

    Hydrosynthesis Institute, Northeast Consortium for Hydrologic Synthesis

    • Goal: to address the history of human influence and decision making on the hydrology of the Northeastern United States, focusing on hydrologic changes during the period surrounding the Industrial Revolution (1800-1920).
    • Current group effort to present findings at AGU Fall Meeting 2009.

    Experimental Flows Working Group, National Center for Ecological Analysis and Synthesis (NCEAS)

    • Goal: to evaluate responses of freshwater ecosystems to experimental water management with respect to large-scale flow experiments.
    • Current working group effort focused on establishing a database of large-scale flow experiments where streamflow and stage have been intentionally altered for an ecological outcome.
