The aim of the present research is to analyze and evaluate the impacts of Water surface Roughness and friction on open channel shallow water flow. The basic models including local water depths, velocity profiles, bed scour, erosion and corrosion rates, sediment transport, scale formation and various hazard indices are analyzed.
The primary research questions of the dissertation include:
The secondary data would be the main source for literature review. Secondary data comprised of academic and commercial sources is also named as multiple source data. Which is further divided into time based and area based series of data. Our literature review would follow the following series of sources:
Both of the series follow academic sources as well as commercial sources including
The aim of the project is to analyze the behavior of fluid flow under the effect of hydraulic losses, the objective or aim is not very general but requires a detailed research to investigate the problems and their remedies. An inductive research approach is required to reveal the important impacts of water surface roughness and analytical research approach is required to calculate the level of hydraulic loss.
A multi-method study approach would be conducted in this dissertation. The multi-method research strategy would include the primary and secondary data collection approach. An inductive approach would be applied to structure the research findings and establish mathematical assumptions.
In this section a primary data would be presented which is extracted from the semi-structured part of the dissertation. It would involve qualitative analysis, analytical induction and mathematical calculations.
This research is based on various techniques to study the hydrodynamic performance of the waves that are incident on open channel shallow water flow. The hydraulic losses due to the water surface roughness are presented with various techniques and methods to calculate their major impacts. The dissertation is intended for application to normal flow conditions and to specify the important limitations to avoid undesired flow regimes.
