Which type of wells are commonly used near the shore of a lake or near a river to obtain a large amount of relatively good quality water?

Radial wells are specifically designed to maximize water intake from aquifers located near the shore of a lake or along riverbanks. The construction of radial wells involves a central vertical shaft from which multiple horizontal or angled wells radiate outward into the surrounding aquifer. This design enhances the well's ability to draw substantial amounts of water by increasing the surface area from which water is extracted, allowing for efficient collection from different directions.

In locations close to bodies of water, such as lakes and rivers, the groundwater often has a strong connection to surface water sources. Radial wells can effectively utilize this connection, providing a sustainable yield of relatively good quality water due to the natural filtration that occurs as water flows through soil and sediment.

While vertical wells can also be used to extract groundwater, they are generally less efficient in high-yield settings, especially in sandy or gravelly riverbeds or lake shores where radial wells can optimize the collection process. Tube wells and piezometric wells serve different purposes and are not primarily used for large-scale water extraction in the same efficient manner as radial wells. Tube wells typically consist of a deep borehole with a pump, and piezometric wells are used to measure groundwater levels and pressure, not for large withdrawals. Therefore, radial
