Drainage
Analysis, Tracts A & B, Lubbock Medical Center
Drainage
in the Lubbock, Texas area is different than most parts of the United
States. The topography is relatively flat and runoff typically flows
along the surface to landlocked depressions called Playa
Lakes. Storm
sewer systems are rare due to topographic constraints and consequently,
roadways are used to convey runoff toward the Playa Lakes. Storage
in the Playa Lakes is recovered only through infiltration and evaporation,
both slow processes.
AMD
Engineering in Lubbock was contracted to perform a detailed drainage
analysis of Playa Lakes 105, 71 and 47 of Playa Lake System C and Playa
Lakes 48 and 51 of Playa System B in support of site design work for the
Lubbock Medical Center. AMD elected to use ICPR for the modeling
effort because of its ease of use for interconnected pond
systems.
In particular, they were able to more accurately model flow splits using
actual box culvert and channel data instead of resorting to simplified
rating curve assumptions as was previously done and is required in an
equivalent HEC-1 model.
In
addition to determining flood levels in the various Playa Lakes, AMD also
used ICPR to assist in designing roadway cross sections to carry the
100-year flows.
