Examples:

1. Simple unsteady flow: Beaver Cr –unsteady flow
2. Simple unsteady flow: Beaver Cr –unsteady flow with culverts
3. Detention pond (storage area): Beaver Cr –storage area

Class exercise: Create river geometry for HEC-RAS

STORM CAD:

1 Pipe Example

Homework: Due 10/24

For the data given in the StormCAD example as shown above (1 pipe example), use Manning equation to find (design) the pipe diameter.

Frequency Analysis of Unsteady Flow

FEMA Flood Analysis Method

Home work due Nov 14:

Using following data to do frequency analysis,

Note: T= (n+1)/m, n= total number of sample, m is the mth largest value, T is the return year.

1)Find 100-year flow value using linear regression

Example of Flow data

2)Analysis using Gumbel method to predict 100 year flow

2-a) traditional method (textbook method) for parameter estimation

Reading : other method in determining Gumbel parameters

L-moment method in parameter estimation (see

Recent Journal paper [1], [2] on using L-moment method in estimating parameters in Gumbel distribution
