Brief introduction of topography and geomorphology in Dangshan county;

1, abandoned Yellow River high beach

It is a riverbed deposit above the ground formed by the Yellow River and its spillway under the increasing constraints of artificial dikes. Including the old Yellow River course and floodplain, with a width of 10-20km. Therefore, the width of the sandy waste channel of the Yellow River is 1- 1.5km, and both sides of the waste channel are natural dikes (0.5- 1.0m wide).

2. Crevasse sector system

When the Yellow River overflowed, the flood burst and overflowed to the plain outside the dike, and it was silted up due to the decrease of velocity. With the expansion of the overflow range, a fan-shaped terrain is formed that spreads outward from the embankment. There are three fan-shaped crevasses in this county, one is the upper reaches of Miaocheng River on the north bank of the old Yellow River; The second is the upper reaches of Shahe River and Limin River in the west of Dangshan City.

3. A flat slope

It is deposited by the flood of the Yellow River, and it is the most widely distributed and largest landform type in the county. The terrain is gentle and slightly inclined from north to south and from west to east. The ground slope is about110000. The groundwater level is 2.5-3 meters. The salt content of groundwater is about 65438 0 g/L.

4. Shallow and flat depressions

Shallow depressions are distributed in Xiaoshenhu depression area in the southeast of the city. The upper layer is mainly heavy loam or clay deposited by still water. The altitude is 40-42.5 meters, which is lower than the gentle slope. The terrain is low and flat, and the ground gradually inclines from the periphery to the center. The gradient is 1/5000 to110000. In general, the groundwater level is below 2m a year, 2.5m in dry season and about 1 m in wet season, and the groundwater salinity is below 1 g/L. ..
