At the onset, in 2008 monsoon studies were completed on the Nallah and the Shriram Institute conducting the volumetric assessment of the Nallah during the peak season. Some of the key findings of the study were that the water in the Nallah rises by a maximum of half a meter during peak monsoon and during that period, the volume of water increased three times from the pre- monsoon values. Reports also suggested that the quality of water proved to be better as the excess rain water diluted the pollutant levels in the water. A photographic documentation of the Nallah was also carried out on and post high rainfall days.

The studies revealed that the landscape design will take into account for the maximum flow.

In addition to the tests, several discussions were also held with environmentalists/ environmental engineers who suggested that the land around the Nallah could be used to plant many fruit and flowering trees that not only help in beautification but also help in holding the soil together and cleansing the wastewater before it reaches the river.
In 2015, A survey for the 3.5 kilometre long remaining stretch of the nallah from Nizamuddin till the river Yamuna was carried out to determine ground levels and rate of water flow.
