Flow estimation for stream restoration and wetland projects in ungaged watersheds using continuous simulation modeling
… the generalization of a parsimonious conceptual continuous simulation model. In this study the Probability Distributed Model (PDM), was generalized for the Maryland and Virginia Piedmont. Two hundred and sixty years of daily average flow data from fifteen watersheds were used to calibrate PDM. …

Formulation and testing of a distributed triangular irregular network rainfall/runoff model
In this thesis, a new distributed, continuous simulation model is developed for flood forecasting. This new model, tRIBS (triangulated Real-Time Interactive Basin Simulator), is created by integrating two models previously developed. A landscape evolution model, CHILD, is used to create the …

Bond graph model and computer simulation of a hydrostatic drive test stand
… approach and was implemented using the Advanced Continuous Simulation Language (ACSL). The test stand was used to obtain experimental data to try to refine the model parameters. To facilitate the measurement of system flows, a microprocessor-based digital flow indicator was developed. …

A novel approach for large-scale flood risk assessments
… damage probability to derive flood risk. With a continuous and long term simulation of the entire flood risk chain, the spatial variability of probabilities could be consider and flood risk could be directly derived from damage data in a consistent way. The objective of this study is the …

Sensitivity of Stormwater Management Solutions to Spatial Scale
… as data from October 2005 to March 2010 for a continuous simulation. The runoff volume reductions achieved by implementing bioretention cells were not substantial for the event storms. For the continuous simulation analysis, however, about twenty percent reductions in runoff volume were …

Using computer simulation to reduce costs at a recirculating aquaculture facility
… This effort uses a combination of discrete and continuous simulation to model this system. Changing the values of a certain set of variables (regressors) result in changes to another set of variables (responses). So the inter relationship between the regressors and responses are first defined. …

Predicting Sediment Detachment and Channel Scour in the Process-Based Planning Model ANSWERS-2000
ANSWERS-2000, a continuous simulation, distributed parameter nonpoint source model for simulating runoff, sediment, and nutrients from disturbed watersheds was updated to include a critical-shear rill detachment subroutine, an improved interrill detachment subroutine, and a channel scour …

Water quality and hydrological assessment and modeling of bioretention basins in tropical cities
… a combination of field observations and model simulations to recommend practical engineering strategies to design and manage bioretention basins in the tropics. First, field observations on water quality performance in six sampled events show that removal targets for total nitrogen, total …

The Use of Stormwater Modeling for Design and Performance Evaluation of Best Management Practices at the Watershed Scale
… test the BMP modeling abilities of EPA SWMM 5.0. Simulations are performed using one-hour design storms and yearlong hourly rainfall traces. From these simulations, small water quality benefits are observed at the system level. This is seen as encouraging, given that a relatively small amount of …

GIBSS: a framework for the multi-level simulation of manufacturing systems
… are heterogeneously specified. Computer simulation modeling is currently the most flexible method of manufacturing system analysis. When used in the multi-level design process, two forms of simulation models are encountered, uni-level and multi-level. A simulation model of a manufacturing …

Hydrologic Evaluation of Low Impact Development Using a Continuous, Spatially-Distributed Model
… cost of long-term paired watershed monitoring, continuous, spatially-distributed hydrologic modeling was judged a better method to compare the response of LID, forest, and conventional development. Review of available models revealed EPA-SWMM 4.4H as the most applicable to the task. A 4.3-acre …

HSPF modeling of the Charles River Watershed
… used for this project is HSPF, an EPA-sponsored continuous simulation model. Based on land use information from MassGIS, six land use types-open space/agriculture, wetland/riparian, forest, highdensity residential, low-density residential, and impervious land-were defined. The watershed was …
