A MATHEMATICAL MODEL OF THE HYPORHEIC ZONE FLUIDIZATION
Journal Title: Biuletyn Państwowego Instytutu Geologicznego - Year 2018, Vol 471, Issue 471
Abstract
In the hyporheic zone, exchange of surface water and groundwater takes place. During the groundwater drainage and the increase in hydraulic gradient, this zone can be fluidized. The paper presents a mathematical model of hyporheic zone fluidization. It has been obtained from a balance of forces related to the water filtration through the hyporheic zone. The mathematical model makes it possible to predict the occurrence of fluidization depending on the increase in water table position. A series of laboratory tests were carried out, which confirmed the predictions according to the model. The hydrological and hydrogeological influences of hyporheic zone fluidization were also analyzed, namely: the decline of diurnal water level fluctuations in headwaters and the variable rate of decline of water level after rainfall flood.<br/><br/>
