Bioengineering plays a vital role in soil conservation and stabilization, particularly in controlling erosion along riverbanks originating from the Chure (Siwalik) range. These rivers are seasonal, with little to no surface water during the dry season but experiencing unexpectedly powerful floods during the monsoon period. In the Terai region of the Chure range, water‐induced disasters such as soil erosion, debris flow, landslides, and flooding are common. This study aimed to explore and rank the existing bioengineering and civil engineering techniques implemented along riverbanks in the Chure Terai around the Likma Kataini River. By examining the case of the Likma Kataini River in Gauriganga Municipality, Ward 8, Kailali, the study investigated how bioengineering contributes to soil conservation and riverbank stabilization and supports structural engineering to extend their lifespan. Data were collected through field visits, household surveys, and discussions with key informants, technical teams, and experts. Quantitative and qualitative methods were used to analyze the data. The findings revealed that bioengineering techniques such as grass plantation, bamboo plantation, deep‐rooted species plantation, bamboo toe wall, fascine, and palisade played crucial roles in preventing riverbank erosion and river channel shifting. Bioengineering techniques significantly supported engineering structures, with the vegetation proving to be sustainable over time, self‐regenerating, and able to respond dynamically to changing site conditions. Therefore, applying bioengineering techniques alone or in conjunction with structural engineering is the best solution to conserve the Chure Terai region. Governmental and nongovernmental institutions involved in Chure conservation should focus on scientifically sound implementation and provide local communities with training to achieve the conservation goals effectively.
