The kind of software I am looking for, is one which is good for simulating single storm events in an urban setting. Also, the software should be able to simulate vegetation characteristics like evapotranspiration and interception, and infiltration through soil macropores like the conduits along roots and such. I know MIKE SHE has a lot of such characteristics, but it's proprietary and not licensed to students of Bangladesh. Thus, I was looking for an open-source software that has all these characteristics.
