Renqiu is a typical low plain landform, with hills, slopes, depressions and lakes all over the country, and narrow strip hills dotted among depressions. Gangdi is mainly distributed in the south-central and east, covering an area of 226 square kilometers, accounting for 2 1.9% of the city's area. The terrain is relatively high, more than 8 meters above sea level. The sloping land is located between hills and depressions, with an altitude of 6-8 meters and an area of 452.5 square kilometers, accounting for 43.8% of the total area. The depression is located at the lower end of the slope, relatively depressed, with seasonal water accumulation, with an altitude of 4.5-7.5m and an area of 3 1 1.26 km2, accounting for 30. 1% of the total area. The north-east hills divide the city into three roughly parallel belt-shaped depressions in the east, west and middle, and the belt-shaped depressions are divided into several Kondo-shaped depressions of different sizes by secondary hills. The relative height difference between hills and depressions is 2-3m, and the slope is 1/2000- 1/3000. Depression Lake is mainly Baiyangdian Lake, which is a perennial lake, accounting for 4.2% of the total area. surface water

Renqiu city is located in the low plain area, where surface water flows freely and flows from west to east and north along the terrain. All the rivers in the territory are the south branch of Daqing River system, and there are no natural rivers. Most of them use the original natural drainage ditches to dig irrigation and drainage canals manually. The larger rivers are: Guyanghe in the eastern region, which originated in xian county and has a total length of 54.89 kilometers; The Xiaobaihe River in the western region, originating from Suning, has a total length of 48.7 kilometers.

Vertical distribution can be divided into one-layer structure (full fresh water), two-layer structure (shallow fresh water, brackish water or brackish water below) and three-layer structure (shallow fresh water, middle fresh water and deep fresh water). The sand layer becomes thicker from shallow to deep, and the number of layers is from less to more, and the thickness of single layer is from thin to thick.
