Abstract :To protect underlying soil erosion on which foundation base is provided like apron provided in water retaining structure like dam, weir etc. In flood zone area this apron is provided at foundation base of building, near village which is situated near bank of river underlying soil erosion will be prevented when apron is provided. Near bank of river (village situated) for protection of village near bank of river analysis is done as follows: Erosion of the underlying soil is one of the most critical challenges in civil engineering as it directly threatens the stability and service life of structures. Continuous scouring caused by river currents, floods, and seasonal variations in water flow gradually weakens the foundation soil, leading to settlement, tilting, or even collapse of the superstructure. To mitigate this risk, the provision of aprons at the foundation base has proven to be an effective protective measure. Acting as a shield, the apron resists hydraulic pressure and reduces direct contact between water flow and soil, thereby minimizing erosion. In this study, the concept of apron protection is examined with specific reference to villages situated near riverbanks, where soil erosion is more severe during monsoon floods. By extending the apron around building foundations and critical infrastructure, the erosive forces of water are dissipated, preventing scouring and safeguarding the structural base. This technique not only improves the overall stability of foundations but also enhances disaster resilience in flood-prone regions. Therefore, apron protection provides a reliable, economical, and sustainable engineering solution for protecting villages and structures near rivers, ensuring safety and long-term performance against underlying soil erosion
