Study Notes
Morphometric Parameters in Drainage Basin Analysis
- Drainage density is a morphometric parameter used in the analysis of a drainage basin.
- Drainage density represents the total length of streams in a watershed per unit area.
- High drainage density in a watershed results in higher flood peaks.
- Drainage density is inversely proportional to flood level in a watershed, meaning high drainage density leads to lower flood levels.
- Drainage density is defined as the ratio of the total length of the stream over the contributing area in a drainage basin.
- High drainage density can lead to a shorter time of concentration and a higher magnitude of flow in a watershed.
- Stream frequency, which is the number of streams per unit area, is a morphometric parameter that affects both the time of concentration and magnitude of the flow in a watershed.
- Low drainage density in a watershed results in lower flood peaks and a longer time of concentration.
- Circulatory ratio, which is the ratio of the circumference of the basin to its diameter, is NOT a morphometric parameter used in the analysis of a drainage basin.
