Urbanization and Its Effect on Storm Water Management
摘要
Rapid growth and development of Urbanization leads to surface runoff, which ultimately become storm water. Sometimes draught and flood like situation may arise because of improper drainage system. It affects the rate of infiltration of soil through decades due to various reasons like soil erosion, concrete pavements, less vegetation etc. Urbanization increase through decades 1990, 2000, 2010, 2020 are evaluated from various modern tools as GIS (Geographical Information System). Rate of infiltration in urbanized area has changed drastically from previous decades. The changes are incorporated in SWMM (storm water management software) for analyzing proper drainage system. Application of LID (low impact development) on catchment area can reduce surface runoff and increase the infiltration rate of soil. Proper drainage system of storm water is a necessity in urban areas.
