IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Moving boundary method based on refined coupled model for surface water and groundwater flow
Author : YUANYI LI(1), & DEKUI YUAN (2)
ABSTRACT
To deal with the moving boundary, this paper presents a fully coupled model simulating surface water and groundwater
flows in coastal areas. In this model, computation domain was extended into bank with water exchange and interaction
between the groundwater and surface water being taken into account. Governing equations for surface water and
groundwater are combined and integrated from the bottom of the groundwater to the free surface. Using this fully coupled
model, beside the moving boundary was conquered naturally, the surface water flow and groundwater flow can be
simulated simultaneously in a uniformed numerical scheme. Several numerical tests were conducted to validate the
model. The comparison results show that the model could well deal with the moving boundary and used to study the
interaction between the two kinds of flow in coast.
