Abstract

Riparian sandbar serves as a habitat for some organisms, which is supported by material transport. Sandbars have vegetated area and bare area, each of which support different material cycles based on subsurface water flow. Understanding the importance of water flow, we focused on subsurface water and solute transport processes through sandbars, and monitoring was conducted through measurement of water level of surface and subsurface water and concentration conservative ions. Particularly Cl- gives us time information using its dilution ratio in bare and vegetated sandbar. Additionally by using their ion concentration and flow patterns and retention time for each monitoring well, and the results of 2-D flow analysis of unconfined groundwater, the effects of precipitation and flood are discussed.
