Other Outside Service
- Member, local organizing committee for the Water 2004 conference that was held in Urbana in October, 2004.
- Surface-water hydraulics and hydrology, emphasis on measurement methods; urban stormwater drainage systems, including best management practices, risk-based design, and real-time control; and reliability-analysis applications for in water-resources and environmental engineering.
Dr. Schmidt's research interests are in the study of surface-water hydraulics and hydrology, with particular emphasis in two areas: (1) providing better understanding of the hydraulics and hydrology of urban storm-water management systems and (2) provide improved measurement and quantitative description of streamflow and related parameters, including quantification of the uncertainty in the reported values.
In the area of urban hydrology and hydraulics, Dr. Schmidt’s research seeks develop improved methods to simulate the complicated hydrologic and hydraulics processes in complex urban environments, to develop methods to quantify the effect of various Sustainable Urban Drainage System (SUDS) practices on the hydrology and hydraulic behavior of urban systems, and to develop and apply improved sensors for hydraulic measurements, particularly in complex environments such as urban and agricultural systems. Dr. Schmidt and his students have developed new numerical models to simulate the hydrologic and hydraulic response of urban drainage systems. In particular, his team has developed probabilistic urban models for catchments where the data describing the hydrologic properties of the catchment and the hydraulic parameters of the drainage system are too sparse to allow a deterministic model. He and his students have developed a system of models that allow different levels of sophistication depending on the objectives of a given study and applied these to a study of the drainage system for the 970 km2 watershed served by the Tunnel and Reservoir Plan in Chicago. This system allowed fast simulations coupled with a genetic-algorithm optimization to examine real-time control rules for stormwater gates and pumps, yet also could provide simulation of hydraulic transients in the tunnel system. This system continues to be expanded, with on-going research to incorporate sophisticated small-scale simulations of the hydrologic response of SUDS practices (green roofs, rain gardens, etc) into both probabilistic and deterministic catchment models and apply these to examine the impacts of SUDS at the catchment scale and under potentially changing climate scenarios.
In the area of developing methods to provide improved measurement and quantitative description of streamflow and related parameters, Dr. Schmidt is working to study new methods to apply multi-platform sensor systems (e.g., LiDAR, GPS, ADCP, water-quality sensors) to measure entire reaches of streams, to merge the data from the different sensors, and then to use the resulting data base to improve the analysis and understanding of entire reaches of streams. Dr. Schmidt has applied these tools to provide fine resolution maps of shear stress, habitat suitability, and hydrokinetic power potential and is currently developing tools to apply these tools to provide better calibration and validation of 2-D and 3-D hydrodynamic models.
Undergraduate Research Opportunities
In the past three year Dr. Schmidt has supervised eight undergraduate students doing REU research on topics including examining data from monitoring rainfall on and runoff from conventional and green roofs,modeling sustainable urban drainage systems, examining uncertainty in different measurement methods utilizing acoustic Doppler current profilers (ADCPs), and developing probabilistic methods to optimally schedule sewer maintenance.
