The costs associated with these tasks for management can be minimized considering the fulfillment of objectives of environmental and regulatory compliance. Nonlinear and mixed integer nonlinear programming (MINLP) formulations with discrete and binary variables is developed in this study to obtain an optimal design for a multiple stormwater detention pond system. The main objective considered is the minimization of cost constrained on system performance related to pollution control. Analytical probabilistic expressions in mathematically closed form for system performance depicting watershed hydrology, control system hydraulics and pollution removal processes are integrated into the optimization formulations. Gradient-based NLP and genetic algorithm-based solvers are used to obtain optimal solutions. Application of the methodology is demonstrated with a hypothetical case study system with realistic hydrologic and water quality parameter values and the benefits of solutions for effective pollution control are reported. Results from the solutions of the formulations provide optimal design parameters considering the runoff control and pollutant reduction considering environmental and regulatory constraints. A comparison of results from these formulations to those from a dynamic programming (DP) formulation developed in an earlier study indicates that limitations associated with discretization within DP can be overcome with the proposed optimal formulations.

Research paper thumbnail of Storm Event Characteristics Based on IETD for Different Climatic Regions within United States

World Environmental and Water Resources Congress 2013, 2013

Given the climate variability and change throughout the world, local level continuous assessment ... more Given the climate variability and change throughout the world, local level continuous assessment of storm event characteristics is critical for analyzing adequacy of existing urban drainage infrastructures and for updating the critical rainfall information for future hydrologic designs. Given such new information, it is instructive to analyze this key input to the most of the stormwater management planning, analysis, design, and operation. Based on the Inter-event Time Definition (i.e., minimum dry period between storm events, or IETD), a long-term point rainfall record can be analyzed for different storm event characteristics such as event volume, event duration, event average intensity, and inter-event time. Such analysis will provide valuable information to our engineers, water resources professionals, and regulatory authorities about the change in storm event characteristics (i.e., storm event volume for different durations) over time at a specific location. This study evaluates storm event characteristics based on varying IETDS for different climatological regions within the United States. The available long-term hourly rainfall records at the representative stations within each of the climatic regions have been employed to conduct the analysis. The analysis will provide the storm event characteristics, particularly event volume and duration over time and their statistical analysis and spatial variability in a region and across different climatic zones. Such information is very useful for volume-based hydrology for managing urban stormwater management systems. The paper presents preliminary results of an ongoing study.

Research paper thumbnail of Precipitation Extremes and Climate Change: Evaluation Using Descriptive WMO Indices

World Environmental and Water Resources Congress 2012, 2012

Assessment of spatial and temporal extreme precipitation events due to climate variability and ch... more Assessment of spatial and temporal extreme precipitation events due to climate variability and change is critical for future hydrologic design. Evaluation of these extremes in the past has been limited to evaluation of annual and partial duration series. However, climate-change sensitive hydrologic design requires evaluation of precipitation extremes at different temporal levels using a variety of indices. This study evaluates the variability of precipitation extremes in two climatic regions in the U. S. using WMO (World Meteorological Organization) proposed and adopted eleven indices. These indices relate to precipitation extremes at a daily temporal scale and encompass a variety of conditions including user-defined precipitation thresholds. Quantitative evaluation, statistical analyses and spatial variability of indices in a region as well across different climate zones indicate that infilling of precipitation data and existence of in homogeneities influences the assessment of trends in extreme events using indices. This paper presents preliminary results of an ongoing study.

In the recent years there is a strong growth in solar power generation industries that requires prediction of solar energy to develop highly efficient stand-alone photovoltaic systems as well as hybrid power systems. In order to accomplish the goal, we propose a predictive model that is based on recurrent neural networks trained with the Levenberg-Marquardt backpropagation learning algorithm to forecast the solar radiation using the past solar radiation and solar energy. This computational intelligence modeling tool explored the impact of solar radiation and solar energy in forecasting reliable long-run solar energy. Based on the excellent experimental results including the mean squared error analysis, error autocorrelation function analysis, regression analysis, and time series response, it demonstrated that the prop...
