The topography of Daman is remarkably flat, typical of an estuarine coastal plain. Its elevation barely rises above sea level, averaging about 5 meters (16 feet). There are no significant hills or mountains within the city limits or the district.
Coastal areas are characterized by sandy stretches, rocky outcrops, and tidal mudflats. The river valley of the Daman Ganga is shallow and widens significantly as it approaches the sea, creating a broad, low-gradient flood plain. The coastline itself is relatively straight, lacking deep natural bays but featuring sandy beaches that slope gently into the Arabian Sea.
