And it costs just a fraction of what you would pay in a full- or part-time MBA program, or for that matter, an online MBA or Executive MBA program. Starting HEC-RAS Steps in Developing a Hydraulic Model With HEC-RAS Starting HEC-RAS: To Start HEC-RAS from Windows: Double-click on the HEC-RAS Icon. You can do it without having to quit your job or make long sacrifices of time from your family. Instructor and student exchanges occur in the virtual world through such methods as chat, e-mail or other web-based communication.Īfter all, taking an online course from a big brand business school doesn’t require weeks or months of studying for a standardized test. Online students may participate in live interactions and real-time feedback for such things as quizzes and tests. Yes, online schooling is the best idea for every learner. The most important tip for anyone attending or considering an online degree is to stay on task. Create visual aids like charts, story webs, mind maps, or outlines to organize and simplify information and help you remember better.
Make studying less overwhelming by condensing notes from class.
This study presents an innovative watershed modeling approach using GIS models while addressing the limitations of traditional hydrologic and hydraulic methods using WPBW as an example.For every 30 minutes, you study, take a short 10-15 minute break to recharge. This study validated use of LIDAR elevation data in floodplain analysis for the second-order streams in coastal NJ.įinally, an approach was demonstrated using modeled floodplain and HEC-HMS for flood control analysis. The modeled floodplain demonstrated close agreement to the observed floodplain for the October 2005 storm and showed greater accuracy compared to the FEMA floodplain for the 100-year storm. This innovation was important for improving model efficiency. Detailed elevation data (LIDAR information from Monmouth County) was incorporated into the HEC-RAS using GIS models. Discussion of output formats available from HEC-RAS (e.g., charts, tables, figures). Generate program files, perform analysis and review output. Input data for open channel, copy cross sections, and interpolate cross sections. Floodplain analysis was done using ArcGIS, HEC-GeoRAS and HEC-RAS. HEC-RAS input files for example problem with single triangular open channel. Applying GIS techniques in hydraulic modeling eliminated this constraint. Using hydraulic modeling techniques (e.g., one-dimensional/two-dimensional (1D/2D) hydraulic modeling, dam break scenarios) for extracting the flood. These updated parameters provide new technical information for improving stormwater management in coastal areas.Īn important limitation in hydraulic modeling is the economic constraint on cross-section spacing for surveying channels and floodplains. 284) and 5% initial abstraction ratio provided better characterization of stream response. The HEC-HMS modeling results indicated use of a lower peak rate factor (e.g. In this study, Wreck Pond Brook Watershed (WPBW), a coastal New Jersey area was used for sensitivity studies of the initial abstraction ratio and peak rate factor. The design of flood control structures based on these flow values allow more post-development discharge, make the system more hydraulically efficient, increase project costs, and cause flooding for areas downstream. Description: This tutorial is designed to expose users to basic functions in HEC-GeoRAS for pre- and/or post-processing of GIS data and HEC-RAS results for. These average values overestimate peak flows for flat, low-lying coastal terrains. Several parameters inherent to these empirical methods are average values derived from various watershed conditions. Soil Conservation Service methods are used widely in hydrologic models. GIS applicability in watershed modeling is increasing due to the availability of spatial information, fast processors and interfaces such as ArcHydro, HEC-GeoHMS, and HEC-GeoRAS linking hydrologic and hydraulic models to the ArcGIS environment. A watershed model should provide temporal and spatial distribution of runoff response for a given storm. Description Managing stormwater on a watershed basis is considered the best strategy to address flooding.
