1. Input the catchment area.
2. Input the overland sheet flow path length, slope, and manning coefficient to obtain the overland flow time of concentration.
3. Choose the construction period of *less than 2 years* for 3 months ARI or *more than 2* *years*for 6 months ARI.
4. Click the “ **Calculate**” button to obtain the required area and volume.

## **Basin Sizing**

Calculate overall dimension of setting and sediment storage zone by inputting data in **Basin Sizing**tab.

1. Settling Zone

a. Input settling depth, y~1 (parameter: min. 0.6m)

b. Input average width, w~1

c. Input average length, L~1 by referring to the range proposed.

d. Click “ **Calculate**” to obtain average surface area, L ~1/y~1 ratio and L~1/w~1 ratio.

1. Sediment Storage Zone

a. Select side slope (H):(V)

b. Input sediment storage depth, y~2 based on the suggested minimum depth.

c. Click “ **Calculate**” to obtain the overall dimension of settling and sediment storage zone.

## **Outlet Design**

Design the outlet by inputting data in the Outlet**Design** tab.
