Isohyetal method is suitable for all types of catchment without any pre-condition.The isohyetal method is used to estimate the mean precipitation across an area by drawing lines of equal precipitation. In the isohyetal method, precipitation values are plotted at their respective stations on a suitable base map.

Isohyetal Method as an Accurate Estimate of Average Rainfall
The Isohyetal method is a commonly used method to estimate the average rainfall in a particular catchment area. It is considered an accurate method of estimating rainfall because it takes into account the variations in rainfall across the catchment area. Here are the reasons why the Isohyetal method is an accurate estimate of average rainfall:
Definition of Isohyetal Method
The Isohyetal method involves drawing lines on a map that connect points of equal rainfall intensity. These lines are called isohyets, and they are used to divide the catchment area into smaller areas that have similar rainfall intensities.
Accuracy of Isohyetal Method
The Isohyetal method is considered an accurate method of estimating rainfall because it takes into account the variations in rainfall across the catchment area. This is important because rainfall can vary significantly across a catchment area, depending on factors such as topography, altitude, and distance from the coast.
Isohyetal Method vs Other Methods
Compared to other methods, such as the Thiessen method and the Arithmetic mean method, the Isohyetal method is considered more accurate because it takes into account the variations in rainfall across the catchment area. The Thiessen method assumes that rainfall is uniform across a catchment area, while the Arithmetic mean method only considers the average rainfall across the catchment area.
Application of Isohyetal Method
The Isohyetal method is commonly used in hydrology and water resources management to estimate average rainfall in catchment areas. This information is important for designing infrastructure, such as dams, reservoirs, and drainage systems, and for developing water management plans.
Conclusion
In conclusion, the Isohyetal method is an accurate method of estimating average rainfall in a particular catchment area. It takes into account the variations in rainfall across the catchment area and is commonly used in hydrology and water resources management.
