Study Notes
Hydrograph Analysis
- A quick rise on the hydrograph indicates a rapid response to rainfall, suggesting a high proportion of surface runoff and a potentially impermeable or saturated soil.
Hydrograph Characteristics
- The flat part at the start of a hydrograph represents the base flow, which is the flow of water that is already present in the river channel before rainfall.
Hydrograph Components
- A hydrograph typically plots discharge or flow rate on the y-axis, with time on the x-axis.
Hydrograph Analysis Applications
- Comparing rainfall timing with flow in hydrograph analysis helps to determine the lag time between rainfall and runoff, which is essential for flood prediction and water resource management.
Insights from Hydrograph Analysis
- Hydrograph analysis provides insights into the hydrological response of a catchment to rainfall, including the storage and transmission of water through the drainage system.
