The river is 314 km long, with a discharge of 6.099 billion cubic metres. It passes the major settlements of Chengmai Zhen inChengmai CountythenDingchenginDing'an County.The river then turns north, goes over theLongtang DamatLongtang,a somewhat smaller town than Chengmai and Ding'an.

Flooding

flood wallbeing installed on the west side of the Nandu nearDingcheng

The Nandu occasionally floods its banks. For that reason, preventative measures have been taken. For example, near Haikou and in other parts, levees were built, andflood wallswere constructed on the west bank nearDingcheng.

One instance of flooding occurred at a sharp bend in the river at Bushicun village. There in August 2016, on the outside bend, as it had before, water surged and flooded onto the land. The ground there, several metres above normal river level, is strewn with rusted boat hulls from previous floods.19.8207°N 110.3957°W/19.8207; -110.3957
