Summary
The SIPSON model simulates sewer overflow events, including pressurized flow and street flooding. It accurately predicts runoff and flooding levels, improving upon existing methods.
Area of Science:
- Hydraulic engineering
- Environmental modeling
- Urban hydrology
Background:
- Sewer systems face challenges with hydraulic capacity exceedance.
- Urban flooding results from complex interactions between underground and surface flow networks.
- Existing models often use simplified approaches like the 'virtual reservoir' method.
Purpose of the Study:
- To introduce the SIPSON simulation model for analyzing sewer overflow and urban flooding.
- To detail the model's capabilities in simulating pressurized pipe flow and surface runoff.
- To present novel procedures for representing complex urban hydraulic phenomena.
Main Methods:
- Utilizes the Preissmann finite difference method and conjugate gradient method for simulation.
- Incorporates special internal boundary conditions for equivalent inlets.
- Includes procedures for manhole cover loss, basement flooding, and runoff distribution.
Main Results:
- The SIPSON model successfully simulates conditions where hydraulic capacity is exceeded.
- Simulations show water flowing from pipes to streets when inlets are overwhelmed.
- The model demonstrated satisfactory agreement with field measurements of hydrographs and flooding levels in Indore, India.
Conclusions:
- The SIPSON model offers an improved approach to simulating sewer overflows and urban flooding.
- The model accurately captures complex flow interactions in looped networks.
- The developed procedures enhance the representation of real-world flooding scenarios.
