An Evolutionary Polynomial Regression (Epr) Model For Prediction Of H2s Induced Corrosion In Concrete Sewer Pipes, Anna Romanova, Asaad Faramarzi, Mojtaba Mahmoodian, M. Amir Alani
International Conference on Hydroinformatics
The sulphuric acid is a known growing threat to concrete sewer pipes. Acid production is dictated by rapid urbanisation, increased use of hot water and discharge of toxic metals and sulphate containing detergents into the wastewater. Concrete sewer pipe corrosion due to sulphuric attack is known to be the main contributory factor of pipe degradation. Very little tools are available to accurately predict the corrosion rate and most importantly the remaining safe life of the asset. This paper proposes a new robust model to predict the sewer pipe corrosion rate due to sulphuric acid. The model makes use of a …

Evaluating The Effectiveness Of Regulatory Stormwater Monitoring Protocols On Groundwater Quality In Urbanized Karst Regions, Daniel C. Nedvidek
Masters Theses & Specialist Projects
Non-point pollution from stormwater runoff is one of the greatest threats to water quality in the United States today, particularly in urban karst settings. In these settings, the use of karst features and injection wells for stormwater management results in virtually untreated water being directed into the karst aquifer. Currently, no policies exist specifically to provide water quality protections to karst environments. This study utilized a combination of karst stormwater quality data, along with survey data collected from MS4 Phase II communities, and an analysis of current federal, local, and state water quality regulations, to assess the need for karst-specific …

Quantifying Gcm Simulation Uncertainty And Incorporating Into Water Resources Assessment, Fitsum Markos Woldemeskel, Ashish Sharma, Bellie Sivakumar, Rajeshwar Mehrotra
International Conference on Hydroinformatics
Rainfall and temperature, simulated using Global Climate Models (GCMs), serve as key inputs for hydrological models in studying catchment responses to climate scenarios. GCM simulations of rainfall and temperature, however, are uncertain due to model structure, scenarios and initial conditions, which results in biased outcomes if used for hydrological models without due consideration of the uncertainties. In this study, we develop a novel uncertainty metric, square root error variance (SREV), to quantify uncertainties involved in GCM rainfall and temperature simulations as well as illustrate its application for water resources assessment. The uncertainty metric involves converting multiple GCM simulations into their …

Sequential Nonlinear Model Predictive Control Of A Drainage Canal Using Implicit Diffusive Wave Model, Min Xu, Dirk Schwanenberg
International Conference on Hydroinformatics
Model predictive control (MPC) is an efficient control method to regulate water systems, for both water quantity and quality. It can generate optimal control solutions based on model predictions over a finite horizon. There are many ways of categorizing MPC. In this research, the predictive control uses a nonlinear internal model and solves optimization in a sequential manner, thus called Sequential Nonlinear Model Predictive Control (SeNMPC). An implicit scheme is applied on the internal model, diffusive wave model, to avoid time step limitation for model stability. This is often important in real-time control applications where large control time step and …
