The rate of resource consumption today is more than the rate of generation in natural resources. In developing countries, municipal solid waste (MSW) is a growing problem due to heterogeneous composition, non-biodegradability of plastic waste, lack of recycling facilities, high cost of waste collection, transportation and management and environment...

This concept paper describes the behavior of a clogged drain in an event of a heavy rainfall. Solid waste accumulates in drainage systems, heavy rainfall, increased runoff volume and stagnation of runoff flow could collectively lead to sudden flash floods in compact cities. Events leading up to a flash flood attack in a city show a marked similarit...

A moderate rainfall event can lead to harsh flash floods in most of the compact cities. Present urbanization happening in these cities creates an imbalance between generated urban runoff volume and effective drainage capacity. For the survival of these, it is vital in enhancing the efficiency of an urban drainage system. However, it is a complicate...

Floods are the most frequently occurring hazard event among all natural disasters. Poorly prepared compact cities have become prone to flash floods even in a small storm event. Present urbanization happening in these cities creates an imbalance between urban runoff volume and effective drainage capacity. For the survival of these cities it is vital...
