ALLTRANS, INC. has refined engineering models to
precisely calculate detention pond outlet structure flows integrated
over the depth of the detention pond. These mathematical models help
us design outlet structures that stage every storm, not just the
100-year storm, which results in less flows downstream and an
increase of stream and river water quality. Our mathematical models
meet the requirements of both Iowa DNR and the Statewide Urban
Design And Specifications (SUDAS).
ALLTRANS INC has provided storm water management
studies to many clients. We have extensive experience TR-55 computer
programs which are designed for storm water modeling. As design
consultants, we are familiar with standard hydraulic design
procedures and techniques.
