Developing rejuvenation strategies and artificial flood mitigation plans for Indrani River: a case study

Area of Science:

• Environmental Science
• Urban Hydrology
• Water Resource Management

Background:

• Urban areas frequently experience artificial flooding due to inadequate drainage and construction.
• Udupi's low-lying areas are prone to monsoon flooding, largely from the Indrani River.
• The Indrani River, a vital water resource, is threatened by human activities.

Purpose of the Study:

• To propose flood and stormwater management strategies for the Indrani River catchment.
• To assess water quality parameters along the Indrani River.
• To identify sources of pollution impacting the river.

Main Methods:

• Field surveys and water quality sampling at fifteen locations.
• Analysis of pH, dissolved oxygen, and conductivity.
• Evaluation of current river conditions and anthropogenic impacts.

Main Results:

• Elevated conductivity downstream indicates pollution from urban sewage discharge.
• The Indrani River's health is compromised by current human activities.
• Flood risks are heightened in Udupi's low-lying regions during monsoons.

Conclusions:

• Revitalizing the Indrani River can secure drinking water during scarcity.
• Integrated management, including clean-up and improved wastewater treatment, is crucial.
• Long-term strategies require a river basin plan and community involvement for sustained river health.
