Desined riverside area to protect degradation and to clean water as well as serving in soci-economic purposes, recreational areas and ecological values
-
Impervious surface components covering the study area are buildings/rooftops with 1055.97ha and followed by 461.82ha of others impervious surfaces in the study area. Existing parking lots are small in percent (0.09%).
-
Flow accumulation of the site indicates the direction of stream flow and the stream entering to or going out of the site. Accordingly, there is no stream entering to the site and there are two outlets of the sites through which the streams out going from.
-
It is possible to identify the area with potential for creating urban runoff and designing proper nature-based drainage solution. Accordingly, residential area, mixed use area, commercial area, cobble stone street area, asphalt street area is from highest
-
The site has the major potential areas of about 12.49% of the total site to apply the NbDS design. This indicates that stormwater management of the site can be incorporated through nature-based drainage solutions which can help the community.

This study focused on estimating the level of impervious surfaces and nature-based drainage design solutions of Nekemte city. The problem associated with imperviousness in this particular watershed can be reduced by retrofitting through the application of nature-based drainage solutions using the available open spaces and public realms.
There have been many approaches developed to mitigate the flood risk by reconstructing landscapes in previous, such as structural forms including floodwalls or seawalls, floodgates, levees, and evacuation routes. Another approach where nonstructural measures such as removing people and property from risk areas. These two approaches have problems in the environment and socioeconomic of the community. To manage stormwater runoff, this project has been working on a new nature-based drainage solution design and implementation approach called nature-based drainage solution for minimizing the risk of flooding (NBDS-FMF) in Nekemte city, that attempts to incorporate advantages in sustainable urban development.
