Estimate the volume of a hydrograph based on time and flow data.
Enter the flow value directly or estimate it through channel cost equations or cost in control structures such as weirs.
Adds geometric data of channels and weirs and calculates their flow based on the tension or hydraulic load.
To estimate the volume, use two methods: i) the first is cubic tracer interpolation which generates equations (different from a line) every two or three points and the second is the integration by numerical methods with the Simpson rule.
