About

We model a simple steady state catchment and drainage system with stormwater pit and pumps

A catchment is the plan area in which rain falls upon, and flows to drains that serve this catchment.

A particular township may be divided into more than one catchment, and the drains for each catchment may be connected to form a drainage system.

The rainwater collected goes to a stormwater pit and the water is pumped out either to a larger network that eventually discharges into the sea and prevents

localized flooding.

This simulation of the rain water flow is to assist in the design of storm water pit dimensions and water pump sizes

Quiz Answer Key

1. A catchment is the area where rain falls and flows to a drainage system. A township can be divided into multiple catchments, each with its own drainage system that may connect to form a larger network.
2. Rain falls on the catchment area and flows into drains. The collected rainwater is then directed to a stormwater pit where it is pumped out to a larger network, ultimately discharging into the sea.
3. The stormwater pit serves as a temporary holding area for collected rainwater. It is essential for preventing localized flooding by managing the water before it is pumped out.
4. Pumps are crucial for moving water out of the stormwater pit and into a larger drainage network. This process prevents the pit from overflowing and causing localized flooding.

Glossary

Catchment: An area of land where water from rain or snow collects and flows into a common outlet, such as a river, lake, or drain.

Drainage System: A network of natural and man-made channels, pipes, and structures designed to collect and carry away surface water and stormwater runoff.

Stormwater Pit: A structure, often a basin or underground reservoir, designed to temporarily store excess stormwater runoff before it can be discharged, preventing flooding and allowing some settling of pollutants.

Pumps: Mechanical devices used to move liquids from one place to another, in this context, from the stormwater pit to a larger drainage network or outfall.

Simulation Model: A computer-based tool that represents a real-world system or process, allowing users to experiment and observe the effects of different variables without affecting the actual system.

Steady State: A condition in which the input and output of a system are equal, resulting in no net change of the system over time. In this context, it refers to the state of water flow in the catchment and drainage system where the inflow rate is equal to the outflow rate.

FAQ

• What is the purpose of the Storm Water Pit Simulator? The Storm Water Pit Simulator is a JavaScript HTML5 applet designed to model a simple steady-state catchment and drainage system. Its primary goal is to assist in the design of storm water pit dimensions and water pump sizes. By simulating rainwater flow within a defined catchment area, it helps users understand how to effectively manage rainwater to prevent localized flooding.
• How does the simulator model a catchment area? The simulator models a catchment area as the plan area upon which rain falls and flows to drains. It represents a simplified system where rainwater collected within the catchment flows into a stormwater pit. The simulator considers the dimensions of this area when simulating water collection. A particular township may have multiple catchments, and their drains can be connected.
• What is the role of a stormwater pit in the simulation? The stormwater pit in the simulation acts as a collection point for rainwater. Water flows into this pit from the catchment area. The pit's dimensions (likely volume) are a key design parameter that users can explore using the simulation. The simulator will pump water out of the pit to prevent overflow, thus simulating the draining of excess water from a typical system.
• What parameters can be adjusted in the simulation? While the provided information doesn't specify the adjustable parameters directly, we can infer from the description that users would likely be able to adjust parameters related to the stormwater pit dimensions, water pump sizes, and possibly parameters that influence the rate of rainfall. The simulation is designed to allow users to examine the effect of changing these parameters on the overall system.
• What are the practical applications of this simulation model? This simulation model is designed to be a tool for the practical design of stormwater management systems. It can be used to determine appropriate storm water pit dimensions and the required pump capacities to prevent flooding. The simulation can be applied to any catchment area where there is a need to manage rainwater effectively.
