Creating Multiple Catchment Area and Point of Interest
Creating multiple catchment area and point of interest
Outfall placement is an important step in the watershed delineation process. An outlet point should be located within an area of high flow accumulation in the main river or in the sub-river because it is used to calculate the total contributing water flow to the given point. Below example is point-based delineation of watersheds based on the point of interest.
The following sampling points have been created through the point shape creation process to show catchment area and if necessary it is possible to calculate the area and perimeters of each catchment area. Calculation of area and perimeter is possible after converting the raster data to vector data or shape file.
The multiple catchment Id (Multi_Cat_Id) field in the above attribute table is created to capture value for each catchment area. DEM is necessary in any type of analysis or to create catchment areas.
Point based delineation of watersheds is based on the point of interest. I have created 8 points of interest in the above attribute table. Each point related to each catchment area.
My question: Is there any other option to create multiple catchment area or multiple point of interest without creating new field?
