Slope of Catchment Formula:
| From: | To: |
The Slope of Catchment depends on the stream profile, and is defined as the horizontal distance along the mainstream divided by the elevation difference between the two end points of the mainstream. It is a crucial parameter in hydrological studies and watershed management.
The calculator uses the formula:
Where:
Explanation: This formula calculates the slope of catchment based on the time of concentration and the maximum length of travel of water in the watershed.
Details: Accurate slope calculation is essential for understanding watershed characteristics, predicting flood behavior, designing drainage systems, and managing water resources effectively.
Tips: Enter time of concentration in seconds and maximum length of travel of water in meters. Both values must be positive numbers greater than zero.
Q1: What is Time of Concentration?
A: Time of Concentration is a concept used in hydrology to measure the response of a watershed to a rain event. It represents the time required for water to travel from the most remote point in the watershed to the outlet.
Q2: How is Maximum Length of Travel of Water determined?
A: Maximum Length of Travel of Water is the longest flow path from the watershed divide to the outlet point, measured along the main channel.
Q3: What are typical values for Slope of Catchment?
A: Slope values vary significantly depending on the terrain. Steep mountainous areas may have slopes greater than 0.1, while flat plains may have slopes less than 0.001.
Q4: Are there limitations to this formula?
A: This formula provides an estimation and may need adjustment for specific watershed conditions, soil types, and land use patterns.
Q5: How accurate is this calculation?
A: The accuracy depends on the precision of input values and how well the watershed characteristics match the assumptions behind the formula.
