Description

technical field [0001] The invention belongs to the technical field of hydrological simulation, and in particular relates to an integrated slope runoff simulation and monitoring device. Background technique [0002] In the past century, affected by human activities and climate change, floods and droughts have become more frequent, and the problem of water resource shortage has become increasingly severe. Water resource management has become a global urgent issue. Hydrological models predict runoff and are considered one of the most effective tools for water resource management. The process of runoff production and confluence is the core of hydrological simulation, and the parameters of the underlying surface related to slope runoff production are the essential and most critical input of the hydrological model. Due to the highly heterogeneous characteristics of the underlying surface, the runoff mechanism of the slope is complex, and the parameters of the models of the flow-...

Problems solved by technology

However, the parameters measured in limited locations by field tests are difficult to reflect their spatial distribution in the entire watershed, and the field tests require a lot of manpower and material resources; parameters of the region, the results are also subject to large uncertainties

In order to make up for the shortcomings of the two traditional methods, indoor simulations of the runoff process have been carried out at home and abroad, but the existing researches still mainly focus on the collection and measurement methods of runoff in plots, which cannot reflect the runoff of the entire slope. complexity; and due to the lack of overall simulation and monitoring of the underlying surface, it is impossible to solve the problem of obtaining the hydrological parameters of the underlying surface of the distributed hydrological model
