Placing sandbags Thursday in an effort to stop the flooding of homes from Box Elder Creek in Brigham City.

2. Objectives Creation of a function that helps with canal’s inventory.
Creation of function that calculates the maximum flow rate permissible in a canal.
Creation of a function that calculates the surface run off flow.
Creation of a function that identify the possible flood problems in a canal.

3. Methodology All the code was written in VBA Input information.
a) Canal shapefile
b) 8 Flow Direction
c) Properties with owners
6 steps.
Used equations.
Surface Runoff Area using D 8 flow direction and modified David Tarboton code .
Inventory of Canal from Diagnostic Walk Thru
For a selected section
Calculation of Runoff Flow using Rational Equation
Calculation of Maximum Flow rate using Manning Equation
Difference of Runoff and Maximum Flow rate and giving values of 0 and 1 for positives and negatives values.

5. Results To test the model data from Northern Logan Canal was used,
the canal was GPSed only 5 kilometers from
the total 24 kilometers of length
