Preventing the Accumulation of Fine Sediments in Sand Dam Reservoirs: An Analytical Framework and Flume Experiments

Creator:

Ellingson, Joseph M.

Abstract:

Sand dams – low-head dams built in ephemeral streambeds that store water within saturated sediments – are a proven means to increase water supplies for rural communities in arid and semiarid regions. Water percolates into the reservoir-impounded sediments during wet season rains and can subsequently be extracted during the dry...

Using Recession Analysis to Characterize Watershed Responses to Drought

Creator:

Jachens, Elizabeth R.

Abstract:

In the face of climate change droughts are predicted to become more persistent, further intensifying the need for accurately predicting the timing and magnitude of summer streamflow in rivers. In order to determine the sensitivity of a watershed to drought, there is a need to describe what these drought conditions...

Investigating One-way Stream-aquifer Connectivity on Streamflow Predictions during Hydrologic Extremes in the National Water Model

Creator:

Jachens, Elizabeth R.

Abstract:

Surface water and groundwater are intimately connected by a two-way flux between the stream and the underlying aquifers; a complicated yet crucial relationship to represent in models. However, the National Water Model currently only considers a one-way flux, where groundwater can enter a stream but cannot return to the aquifer....
