The Hokuriku region of Japan has many wells used as snow melting facilities. This study treats the practical applications of inland flood control using those wells. The method, in which rainwater is injected directly to the wells, is proposed to prevent inland flooding during rainy and typhoon seasons. Field injection tests were conducted in Mitsuke city of Niigata to examine the effects of the direct recharge of rainwater on the groundwater environment. It became clear that the wells provided sufficient capacity of injection. Although groundwater in the well was changed to rainwater by the injection, the groundwater quality gradually returned to its prior state after stopping the injection. However, clogging substances such as iron bacteria and iron oxide flocks were detected in the well about two days after the injection.

日本北陆地区有许多威尔斯井被用作融雪设施。本研究探讨这些威尔斯井在内陆防洪中的实际应用。提出了将雨水直接注入威尔斯井的方法，以防止在雨季和台风季节发生内陆洪水。在新泻三附市进行了现场注入试验，以检查雨水直接补给对地下水环境的影响。很明显，这些威尔斯井提供了足够的注入能力。虽然井内的地下水被注入变成了雨水，但停止注入后，地下水水质逐渐恢复到原来的状态。然而，在注入后约两天，在井中检测到铁细菌和氧化铁絮凝物等堵塞物质。
