A Remotely Controlled Siphon System for Dynamic Water Storage Management

Creator:: Alnahit, Ali
Abstract:: This thesis presents an analytical, experimental and numerical study of the initiation of flows in a siphon for rapid and gradual openings of a downstream valve. Three initial water levels in the upstream tank and four final positions for the downstream valve were investigated. Two opening times of the downstream...

An Experimental Study on Violent Geysers in Vertical Shafts

Creator:: Elayeb, Ibrahem S.
Abstract:: A Geyser in a stormwater (SW) and combined sewer system (CSS) is an oscillatory and violent release of a mixture of air and water through vertical shafts. Violent geysers are highly destructive. In the case of combined sewer systems, many municipalities operate their systems at a fraction of their maximum...

A novel framework for uncertainty propagation in river systems based on performance graphs using two-dimensional hydrodynamic modeling

Creator:: Gifford-Miears, Christopher H.
Abstract:: This thesis presents a novel approach for propagation of uncertainty in river systems. Errors in data observations and predictions (e.g., stream inflows), in model parameters, and resulting from the discretization of continuous systems, all point to the need to accurately quantify the amount of uncertainty carried through the modeling process....

Biochar : saturated hydraulic conductivity and methylene blue sorption characteristics as applied to storm water treatment

Creator:: Morrow, Perry R.
Abstract:: This study evaluates the use and efficacy of biochar for treatment of source and nonpoint source pollutants in storm water. Biochar is the solid byproduct of incomplete combustion of biomass under low-oxygen and elevated temperature conditions (Keiluweit, 2010, Beesley and Dickinson, 2011, Bracmort, 2010). The source stock for tested biochar...

Multi-objective Optimization of Reservoir Operation Under Uncertainty with Robust and Flexible Decision Variables

Creator:: Hosseini, Parnian
Abstract:: Optimization of reservoir operation is involves various competing objectives for a scarce resource (water). To find the optimal operation of reservoirs, it is essential to consider multiple objectives simultaneously. There are various sources of uncertainty associated with the reservoir operation problem that should be considered as well. The overarching goal...

A dimensional analysis for determining optimal discharge and penstock diameter in impulse and reaction water turbines

Creator:: Leon, Arturo S. and Zhu, Ling
Abstract:: This paper presents a dimensional analysis for determining optimal flow discharge and optimal penstock diameter when designing impulse and reaction turbines for hydropower systems. The aim of this analysis is to provide general insights for minimizing water consumption when producing hydropower. This analysis is based on the geometric and hydraulic...

Bioretention Establishment Hydrologic Characterization with Drift Correction and Calibration of Fine Water Level Measurements

Creator:: Livingston, Grant
Abstract:: Bioretention is a common form of green stormwater infrastructure that is used to attenuate peak flows from urban stormwater. Previous research shows that the bioretention peak response is not consistent across time or space and that the variables that affect peak hydrology are numerous. One variable that has not been...

Analysis of spillway hydrodynamics for total dissolved gas prediction downstream of hydropower projects with free, plunging spillway jets

Creator:: Germann, Nathan A.
Abstract:: During spring and early summer hydropower projects are often forced to spill water through their spillways due to increased river flows of the runoff season. Flows which are directed through spillways--instead of through turbines--contain a substantial amount of energy. Stemming from the high energy content, spillway flows entrain air at...

A Novel Physically-Based Framework for the Intelligent Control of River Flooding

Creator:: Leon, Arturo S. and Gichamo, Tseganeh Z.
Abstract:: River flooding is a recurrent threat and its control and management continues to be a challenge. It has been recognized that effective flooding control requires a real-time strategy that combines optimization with a physically-based simulation model. Current real-time frameworks that combine simulation and optimization have two main drawbacks. The first...

Hydrologic-Hydraulic Model for Simulating Dual Drainage and Flooding in Urban Areas: Application to a Catchment in the Metropolitan Area of Chicago

Creator:: Nanía, Leonardo S., León, Arturo S., and García, Marcelo H.
Abstract:: A one-dimensional (1D) hydrologic-hydraulic model for simulating dual drainage in urban areas is presented. It consists of four modules: (1) rainfall-runoff transformation, (2) 1D flow routing on a street network, (3) flow interception at street inlets, and (4) flow interaction between surface water on the streets and the underground storm-water...
