How do you find the volume of a reservoir?
Square the length of the contour line; Divide the result by 37.5 (conversion factor); Multiply by the assumed maximum water depth (in this case, 1.5 m) to find the approximate reservoir volume.
How do you calculate the volume of water in a dam?
- Surface area. The surface area of a dam is calculated by multiplying the length by the width.
- Volume. With the surface area and depth calculated, the volume can then be determined: volume (m3) = surface area (m2) × max depth (m) × 0.4.
- Gully dams.
- Depth.
How do you calculate bulk volume of a reservoir?
The bulk volume of water (BVW) in a reservoir is simply the product of the water saturation (Sw) times the porosity (ɸ), or stated mathematically: BVW = Sw × ɸ.
What is the water storage capacity of reservoir is expressed in?
These 91 reservoirs have total live storage capacity of 161.993 BCM (Billion Cubic Meters), spread over 18 states and 12 river basins.
How to calculate volume of a sphere in Python?
Python also supports a number of numeric and mathematical functions, including math, cmath, decimal, random, itertools, functools, and operator. Calculate volume of a sphere given a radius field.
How to calculate the volume and surface of a reservoir?
In this case, the result is in cubic meters, since we are working in International System of Units (S.I.): 11,834,796.1198 (equivalent to 11.835 cubic hectometers ). We also got the total flooded surface: 1110140.5082 square meters (equivalent to 111.014 hectares ).
How to calculate the volume of a raster file?
If your raster has cells of equal size then the area is easy enough, as its just the cells size squared. Then you could use the Spatial Analyst – Math – Times tool to multiply each cell times its area to get a raster representing the volume for each cell.
How to calculate volume and surface area of a polygon?
The volume and surface area will be calculated below the reference plane height of the polygon. Leave the rest as default: Click on OK. The calculation process may take several minutes. As the final result, two new fields are added to the “1115_contour_polygon.shp” attribute table: “Volume” and “SArea”.
