The new trend in urban stormwater management is to preserve natural hydrological conditions by addressing changes from urbanization. The software Chaak: Urban Hydrological Impact Modeling is a new hydroinformatics tool designed for sustainable modeling, simulation, and analysis of stormwater sewer networks. It emphasizes two key aspects: enhancing planning for Sustainable Urban Drainage Systems (SUDS) to restore natural hydrological conditions and providing an alternative to conventional storm drainage designs. Additionally, it encourages global scientific collaboration to quickly advance the tool's capabilities through structured development and quality control.
