This study addressed the suitable width for riparian vegetated buffer strips (RVBS) using topographic analyses, attenuation curves, and an index model. The Chi Chia Wang Stream is susceptible to pollution because of highly saturated hydraulic conductivity and excessive fertilizer use in the nearby cultivated lands. The buffer strip widths calculated from a potassium attenuation curve in the vegetable plot were the widest due to easy potassium movement in the soil. A potassium safety soil depth of 8.81 m was calculated or estimated for the vegetable area. The buffer width derived from this safety depth is recommended for maximum agricultural nonpoint source pollution (ANSP) prevention. (c) 2004 Elsevier B.V. All rights reserved.
