Effective drainage systems are necessary to prevent flooding to highways, properties, sites and or lands as well as to conserve resources. The importance of adequate drainage is recognized, for example, in the highway construction dollars to be allocated to drainage facilities, which typically accounts for about 20% - 25% of total construction costs for highway structures such as culverts, bridge, channel, ditches as well as for erosion control. Two important components of drainage engineering are hydrology and hydraulics. The former is the science that deals with the characteristics and distribution of water in the atmosphere on the earth’s surface or in the ground, while the latter is a topic in applied science and engineering dealing with the mechanical properties of liquids for which fluid mechanics provides the theoretical foundation.
EASL Transportation Consultants, Inc.’s founding principals have solid hands-on project experience in drainage engineering, Stormwater Management and project design both in Canada and the US. Our related expertise includes hydrologic and hydraulic modeling and evaluations of drainage features and structures, flood plan evaluations for land development projects, preparing detailed drainage design and complete project PS&E’s of drainage plans, profiles, and construction estimates for highway and land development projects, as well as performing QC review of various highway drainage study reports. Our project work involved both new highway construction and rehabilitation projects and included the evaluation and design for different storm events (frequency), intensity and duration of rainfalls, which are supported by the state-of-the-art modeling programs including but not limited to HEC-HMS, HEC-1 and HEC-RAS.
