At ABE, "WE PROVIDE SOLUTIONS FOR YOUR ENGINEERING NEEDS"
Hydrology Services ABE's Hydrology Department provides technical expertise; planning and design services for civil engineering projects that involve detailed study of hydrologic and hydraulic effects. Hydrology is the study of "the occurrence, circulation, and distribution of the waters of the Earth." In practice, hydrologic studies involve determining the stormwater runoff from an area because of a rain event. Runoff predictions depend upon many complex parameters, including the amount of paved surfaces, soil type, and moisture conditions of the soil, ground slope, and the spatial variation of rainfall. Using a variety of calculation methods and computer model simulations such as the Storm Water Management Model (SWMM) and programs by the U.S. Army Corps of Engineers Hydrologic Engineering Center (HEC), we are able to predict runoff for storm conditions. Combined with hydraulic analysis of specific flow situations, we provide our clients with complete services in a variety of areas to meet their needs, including: • Floodplain analysis to comply with Federal Emergency Management Association (FEMA) regulations for appropriate and responsible develop within existing floodplains • Water surface profiling of streams with bridge crossings or other encroachments • Retention Treatment Basin sizing and design to reduce sewer overflows to local streams • Relief sewer projects and flow metering to reduce basement-flooding backups • Modeling analysis of regional sewer areas to calculate a community's flow contribution • Streambank restoration designs</font> • Detention pond and stormwater management designs to protect streams and sewers from the detrimental effects of "flashy" runoff from paved surfaces • Water distribution network modeling to increase pressure for drinking water and fire protection www.ABE-ENGINEERS.COM Detroit: 313-961-5170
