Diagnosing Drivers Of Reservoir Sedimentation In The Western Us: A Case Study Of Prineville Reservoir, Oregon, Leah Clare Bensching Jan 2019

Diagnosing Drivers Of Reservoir Sedimentation In The Western Us: A Case Study Of Prineville Reservoir, Oregon, Leah Clare Bensching

Civil Engineering Graduate Theses & Dissertations

There is great need to quantify reservoir storage loss due to sediment. Less than 1% of reservoirs in the US have more than one volume survey. Due to the lack of frequent data collection, a constant rate sediment yield from year to year is often assumed. This study aims to explore the following questions: 1) Can hydrologically-forced sediment algorithms help us advance reservoir sedimentation estimates to improve future planning? 2) To which processes and inputs are reservoir sedimentation estimates most sensitive? 3) What can we learn from models that the linear sediment accumulation assumption fails to assess? It will address ...


Informing Many-Objective Decision-Making For Water Rights Allocations And Trading Dynamics Conditioned On A Streamflow Prediction Regime In The Elqui River Basin, Melissa A. Estep Jan 2019

Informing Many-Objective Decision-Making For Water Rights Allocations And Trading Dynamics Conditioned On A Streamflow Prediction Regime In The Elqui River Basin, Melissa A. Estep

Civil Engineering Graduate Theses & Dissertations

The Elqui Valley in northern Chile faces increasing water stress due to a growing agricultural sector. This study evaluates how improvements in season-ahead forecasting skill and changes in water rights trading dynamics impact the ability for seasonal reservoir management to meet the water needs of various actors in the basin. By establishing a baseline forecast of perfect foresight of observed streamflow data, the analysis evaluates how the use of an updated forecasting technique compares to climatology in its ability to meet management needs. Using the RiverWare river system modeling tool, multiple scenarios representing different suites of trade and reservoir operating ...
