That depends on the rate of flow. However, at any one moment, 2,700 cubic feet can contain a maximum of 20,197.4 US gallons of water.
A 1.5 cubic foot per second flow of water equates to 2,592 cubic inches of flow per second.
it is the elevation at the bottom of the inside of a pipe (as if there was a drop of water sitting at the bottom) which typically dumps out of a culvert, or spillway
Box culvert can be described as either a precast concrete or reinforced concrete structure in rectangular figure, facilitating water flow through an embankment of road,etc,as a similar function performed by concrete pipe culvert.
Three cubic feet per second is 80,790 gallons per hour.
65 as a cubic metre is 1000 litres
One cubic footcubic feet per second
" Step 1 Dig out the drainage ditch. Broaden the ditch to roughly twice the width of the culvert and angle the sides of the ditch. Dig about six inches out of the bottom, for the entire length of the culvert. Step 2 Fill the bottom six inches with gravel, maintaining the original level of the drainage ditch. The gravel will allow the culvert to settle evenly and allow for better drainage in the event that water flows around the culvert. Step 3 Place the culvert in the ditch, centering it in the gravel. There should be about one foot of excess length on each end of the culvert. Step 4 Fill in the sides next to the culvert with dirt, tamping the dirt down at regular intervals. Keep the culvert centered in the ditch while doing this; a crooked culvert will cause erosion on the walls of the ditch. Step 5 Cover the top of the culvert. Cover with at least 12 inches of dirt and tamp down well. Cover this with gravel to avoid erosion. Step 6 Tamp the sides of the fill down tightly, making sure they are angled in towards the top. Regular maintenance will be needed to keep the walls from eroding away." and that how u install it

Usually large rocks are placed at the outlet of a culvert to prevent the concentrated outflow of water from eroding and moving sediment and delivering the sediment to larger creeks or undercutting the road.
