Example of the construction of a case study
Take into account the following recommendations:
On this page you will find a description of the elements used in the construction of a case study for users to take as an example. Remember that a case study is built from data of water intakes, treatment plants and the objectives you want to achieve through the implementation of the NbS. Here's why:
- WaterProof relies on the geographic location of water intakes to suggest a basin area in which the NbS will be implemented
- Details of the elements and technologies that are part of the infrastructure of the water intakes and treatment plants are required, because it is assumed that when the NbS are implemented there are a series of savings in the maintenance and operation costs of the infrastructure.
Please follow the steps below:
The example we offer is carried out for the Rio Frio basin in the municipality of Floridablanca, Santander, in Colombia, which is part of the Bucaramanga Metropolitan Area that is supplied with water from the Suratá and Oro rivers. There are approximately 1.160.272 living people there, whose economy is based on the cultivation of beans, tobacco, poultry and the manufacture of footwear and leather goods, among other lines.
Define the location
The example is supported by a water intake located at latitude 7.0740 and longitude -73.0697. The graphic shows the screen in which the water intake name and location were indicated.
Notice that the delimited watershed is shown by analyzing the DEM for the area. WaterProof uses traditional spatial analysis algorithms to delineate watersheds from digital elevation models.
Configure the water intake infrastructure
On this screen, the user built a diagram with the infrastructure that is part of the water intake system:
- The water is extracted from the river, through
- a lateral intake, to lead it to
- a sand trap, and finally to
- the infrastructure of the case study (Drinking Water Treatment Plant - DWTP).
In this section, the cost functions of each element of the diagram must be defined.
Define the estimated water demand
In this example, the user selected the Linear Interpolation method to estimate 30-year demand. However, there are other interpolation methods, and a way to enter the data manually is also provided.
Define the NBS implementation area
The system shows you the watershed area as the total implementation area for the NbS. However, you can modify the area in which you want to implement by moving the vertices of the polygon or by loading a spatial SHP file.
