What is hypsometric integral?
A hypsometric integral (HI) is a topographical index with important geomorphological meaning. It can both describe the development state of the watershed and reflect the strength of activity in the geological structure.
What does hypsometric curve represent?
A hypsometric curve is essentially a graph that shows the proportion of land area that exists at various elevations by plotting relative area against relative height.
What is hypsometric curve in geology?
A hypsometric curve is a histogram or cumulative distribution function of elevations in a geographical area. Differences in hypsometric curves between landscapes arise because the geomorphic processes that shape the landscape may be different.
Who developed hypsometric curve?
The most significant fact emerging from this curve (developed by de Lapparent, 1883; Murray, 1888; Penck, 1894: see Clarke, 1966) was the discovery that the earth’s surface is divided into two statistically distinct “levels” or steps, the continental platforms (about 100 meters above sea level) and the deep-sea floor ( …
What is the formula of hypsometric integral?
A hypsometric integral is usually calculated by plotting the cumulative height and the cumulative area under that height for individual watersheds and then taking the area under that curve to get the hypsometric integral.
How do you calculate hypsometric curve?
How do I read the graph?
- Find 10% on the horizontal axis.
- Draw a line up from 10% until it reaches the hypsometric curve (the dark red curve).
- Now, draw a line across to the vertical axis (at approximately 0.5 km).
- So, you find that 10% of the Earth’s surface has an elevation of 0.5 km or higher.
How do you find a hypsometric integral?
Why is Hypsometry important?
Hypsometry has significant influences on the dynamics of coastal landforms, hydrodynamic and vegetation changes. Artificial structures and development of land use alterations of landforms can influence hypsometry and have lagged effects on coastal evolution.
What is Clinographic curve?
clinographic curve is drawn by plotting the ground slope against the contour height starting at the top of any area. The clinographic curve of the W. Kerak drainage basin is illustrated in (Figure 7). Generally, the shape of the clinographic curve is similar to the hypsographic curve (Figure 8). …
How do you do a Hypsometric curve?
What is the hypsometric integral in geology?
The hypsometric integral is the summary of the shape of the hypsometric curve. Hence, the hypsometric integral is a terrain analysis factor reflecting from the landform erosion stage. The curve has three parameters to fit the different hypsometric relations, as described by Arthur Strahler:
What is a hypsometric curve?
The hypsometric curve defines the elevations of the earth’s surface in the form of cumulative distribution. And the graph given above in the form of a two-dimensional histogram shows the elevation on the vertical y-axis and the area above the corresponding elevation is shown on the x-axis.
Is elevation–relief ratio the best alternative for hypsometric integral estimation?
In this context, as revealed from this study, the elevation–relief ratio method can be the best alternative for hypsometric integral estimation.
What is the meaning of hypsometry?
Measurement of the elevation and depth of features on Earth’s surface relative to mean sea level. Not to be confused with Hypsometric tints. Hypsometry (from Ancient Greek ὕψος (húpsos) ‘height’, and μέτρον (métron) ‘measure’) is the measurement of the elevation and depth of features of the Earth’s surface relative to mean sea level.
