The invention relates to a device and method for monitoring soil erosion. The device mainly comprises a plurality of water collectors, a weighing sensor and a solenoid valve. The water collectors are divided into test water collectors and auxiliary water collectors, and the number of the water collectors can be set appropriately according to the size of a measured land parcel. A mode of matched use of the test water collectors and the auxiliary water collectors is adopted. When water of one test water collector overflows, the overflowing water flows into one auxiliary water collector through an overflow port; after the water of the auxiliary water collector reaches a certain weight, another test water collector is switched to collect water, the weights of the test water collector and the auxiliary water collector and the volume of the test water collector are measured, and the content of sand in water is calculated according to the relations of sand density and water density. After the measurement is finished, the water in the test water collector and the auxiliary water collector is discharged, measurement is performed after the water of the test water collector overflows next time, and the circulation is performed like this. The device has the advantages of being high in precision and efficiency, simple in structure and capable of performing full flow continuous measurement; and the device has wide application prospects in the field of soil erosion monitoring.
