Abstract:
The way the soil is used can vary greatly over time. With the population growth, the need for
urbanization arises. This urbanization becomes a problem when it occurs in a disorderly way,
because the constructions are executed without obeying basic norms such as occupation rate
and soil waterproofing. Urban drainage projects that are dimensioned from this use can be
outdated and thus lose their efficiency. The neighborhood of Pedregal, in Campina Grande,
has a canal that drains the water produced by the basin, known as the Pedregal canal. This was
built more than thirty years ago, during which time the neighborhood of Pedregal went
through some urbanization processes which made the soil much more impermeable,
increasing the volume drained over the basin drained by the canal. In view of the above, the
present work has the objective of verifying the hydraulic efficiency conditions of the Pedregal
canal in the face of the urbanization that has occurred in its surroundings over time, the way
the residents use the canal and make a diagnosis of the structural conditions current. For this,
field visits were made to verify the actual situation of the canal and to make photographic
records, and to observe the flow direction of the water in order to effect subdivisions of the
basin; consultation to the Municipal Planning Department for data collection and from then
on the application of the rainfall-IPHS1 model considering different scenarios of use and also
different design rains. The results show that in the current condition some parts of the channel
overflow even for a return period of 5 years.
