Such tools consist of a three-level procedure which includes qualitative geomorphic analysis, quantitative geomorphic and engineering analysis, and computer or physical modeling. Analysis of erosion and sedimentation using this approach ensures results that are credible, being based on scientifically supportable procedures which are checked for consistency by comparing the various analysis tools as applied to each particular project. These are key variables since they are directly associated with such issues as flooding and sediment transport. Hydraulic analysis is a key component of the analysis of erosion and sedimentation, sediment transport, and channel dynamics. The hydrologic process plays a significant role in hydraulics, sediment transport, erosion and sedimentation, geomorphology, as well as environmental processes.
Hydrology involves the relationship between storms and runoff.
The hydrologic process is often affected in a variety of ways by such as water resources development, general development, and other activities in watersheds and along waterways. This experience has been achieved through the successful completion of hundreds of projects both nationally and internationally. Successful engineering design must incorporate various levels of analysis, depending upon the complexity of the project. The initial phases of design take advantage of experience and knowledge regarding geomorphic processes. The middle phases expand upon this knowledge by utilizing engineering concepts, principles and experience.
