1. How long is the Lyari River?Approximately 50 kilometers (30 miles)
2. What is the location?Karachi, Pakistan
3. What is the primary function?Stormwater drainage conduit for Karachi
4. Why does the Lyari River only flow after rain?It is an "ephemeral stream," meaning it needs rainfall to have water. When it rains, the river carries water from the hills to the sea.
5. How does the Lyari River help Karachi?It drains stormwater, especially during heavy monsoon rains, so the city doesn’t flood. It is one of two main rivers that take water away from the city.

Ephemeral Stream: A watercourse that flows only intermittently, typically after rainfall events, and is dry at other times.
Catchment Area: The geographical region from which surface water drains into a particular river or stream system.
Urban Hydrology: The study of water movement and distribution within urban environments, considering the impact of built structures.
Stormwater Runoff: Water from rain, snowmelt, or other sources that flows over the land surface in urban areas, often carrying pollutants.
