Field assessment for stormwater drainage modelling in expressway design

Abstract

Field assessment is important for storm water drainage engineering in expressway design. Such designs are carried out using hydrologic and hydraulic modeling which involves use of a significant number of empirical equations and site specific parameters .In this work field assessment consisted of identifying river channel parameters, land use, terrain details and flood inundations. The present study describes a methodology to be used to estimate the order of magnitude of flood flows and to carry out systematic field survey.
