Abstract

The invention discloses a novel hydrological prediction model. Modeling comprises the following steps: step 1, a study area and hydrological conditions of the area in previous years are selected; step2, hydrological conditions of the area are predicted; step 3, the hydrological prediction model is established; step 4, computing processing is performed on the hydrological prediction model; step 5,a conclusion is drawn. The amount of precipitation and rainfall distribution of the next year are predicted by mathematical modeling, the hydrological prediction model is established on the basis ofthe predicted rainfall, influence factors including rainfall, loss and total amount of a river network of the area are analyzed, and water amount of the area in the next year is predicated finally, sothat convenient and effective management is realized; the influence factors including precipitation P, surface layer free water S, ground total inflow QS, soil total inflow QI, underground total inflow QG and the like are analyzed comprehensively in the hydrological prediction modeling process, and prediction accuracy is improved accordingly.

Description

technical field [0001] The invention relates to a new hydrological prediction model, which belongs to the technical field of hydrological prediction. Background technique [0002] Hydrological model refers to the approximate scientific model given by the generalization of complex hydrological phenomena and processes by means of simulation methods. According to the simulation method, it can be divided into two basic types: hydrological physical model (solid model, scale model) and hydrological mathematical model. The hydrophysical model is a model with the main physical properties of the prototype (that is, the research object), such as reducing a watershed in the laboratory according to the similar principle, or moving the original soil sample to the laboratory for experiments; the hydrological mathematical model is Follow the principle of similar mathematical expressions to describe the model of the physical process of hydrological phenomena, but do not consider the physica...
