in VOSWMM, the outlet needs a capture curve. Catch basin provides VOSWMM to automatically calculate the capture curve.
A catch basin is a type of inlet structure designed to collect and manage stormwater runoff. In VOSWMM, you typically model catch basins as nodes where runoff from the surrounding area enters the drainage system.
