Determining Catchment Area Contour Map

Determining Catchment Area Contour Map. Topographic map of two catchment areas with terrace (TER) and without Fix the scale of the imported image & retrace the catchment boundary in Autocad using polylines The document discusses how to determine the catchment area or drainage area of a river using contour maps

The area value corresponds to the catchment area, in [m2] The watershed line very well indicates the drainage basin of the river which passes through the ridges and then saddles of the terrain that turns around the river

Determining catchment Area; The area on which fallen rainwater drains into river at a particular point is called catchment area of the river at that point For this, scan the topo map catchment & import it to the Autocad environment ACTIVITY SHEET 1 Understanding Catchments For further information contact Ipswich City Council Phone: (07) 3810 6666 www.ipswich.qld.gov.au ACTIVITY Draw a map of your waterway and its catchment area Materials: • a topographic map of your chosen waterway • an.

Topographical characterisation of the catchment Contour lines. The watershed line which indicates the drainage basin of a river passes through the ridges and saddles of the terrain around the river As an alternative to this graph paper method, we can use Autocad to calculate the catchment area

Catchment Area/Drainage Basin & Watershed/Divide In Engineering. Fix the scale of the imported image & retrace the catchment boundary in Autocad using polylines The area of the enclosed figure which results is the catchment area
