Gayungan District is one of the areas in Surabaya that frequently experiences flooding. Generally, flooding can be categorized into two types: first, flooding caused by dry land being submerged by increasing water levels. Second, flooding caused by overflowing rivers/irrigation channels caused by blockages, which increase the volume of water beyond the rivers capacity. The objectives of this study are: 1) Identifying flood-prone areas in Gayungan District using GIS-based river buffer analysis. 2) Analyzing the distribution of evacuation points and their suitability for flood-affected settlements. Using quantitative descriptive methods. The results show a 300-meter flood coverage zone, with one shelter and worship facility within the flood-affected zone.

This research produced a map of the 300-meter flood buffer in Gayungan District, Surabaya City.Furthermore, evacuation shelters, including religious facilities like mosques and churches, were identified.However, one shelter in Gayungan District remains affected by the flooding.Therefore, an evaluation and relocation are necessary to maximize and optimize the provision of shelter services for evacuation.The resulting maps serve not only as a means of representing and visualizing data, but also as a basis for providing insights for relevant parties in developing disaster mitigation policies and strategies.

Berdasarkan penelitian ini, terdapat beberapa saran penelitian lanjutan yang dapat dikembangkan untuk meningkatkan pemahaman dan penanganan risiko banjir di Gayungan District. Pertama, perlu dilakukan analisis mendalam mengenai faktor-faktor penyebab banjir secara spesifik di wilayah tersebut, termasuk analisis tata ruang, sistem drainase, dan perubahan penggunaan lahan. Hal ini dapat membantu mengidentifikasi titik-titik kritis yang berkontribusi terhadap peningkatan risiko banjir. Kedua, penelitian dapat difokuskan pada pengembangan model simulasi banjir yang lebih akurat dengan mempertimbangkan data hidrologi dan topografi yang lebih detail. Model ini dapat digunakan untuk memprediksi dampak banjir pada berbagai skenario dan membantu dalam perencanaan mitigasi yang lebih efektif. Ketiga, penting untuk mengevaluasi efektivitas dan kapasitas tempat-tempat evakuasi yang ada, serta mengidentifikasi kebutuhan fasilitas dan sumber daya tambahan yang diperlukan untuk menampung jumlah pengungsi yang mungkin terjadi. Penelitian ini juga dapat mengusulkan strategi untuk meningkatkan kesiapsiagaan masyarakat terhadap banjir, seperti melalui program pelatihan dan sosialisasi.
