Abstract

Artan nüfus nedeniyle Akure Federal Teknoloji Üniversitesi'nde (FUTA) su kaynaklarına yönelik artan talebin karşılanması, veri odaklı bir çözüm gerektirmektedir. Bu çalışmada, beş tematik faktör (drenaj yoğunluğu, eğim, yükseklik, arazi örtüsü ve toprak dokusu) ve Coğrafi Bilgi Sistemleri (CBS) tabanlı Çok Kriterli Karar Analizi (ÇKKA) yaklaşımı kullanılarak FUTA'daki su kıtlığı sorununa alternatif bir çözüm olarak mini barajlar için uygun yerler belirlemiştir. Kriterlere baraj için önemlerine göre tercih değerleri atanmıştır. Kriterlerin ağırlıklarını belirlemek için Analitik Hiyerarşi Proses (AHP) yöntemi kullanılmış ve çalışma alanında bir mini baraj uygunluk haritası üretmek için ağırlıklı toplam yöntemi uygulanmıştır. Uygun alanlar beş sınıfa ayrılmıştır: çok uygun (%9), uygun (%18), marjinal olarak uygun (%30), en az uygun (%26) ve uygun değil (%17). Uygunluk haritası, çalışma alanındaki mevcut barajların konumlarına göre doğrulanmıştır. Bu çalışma, FUTA'da artan nüfus için su kaynaklarını yönetme çabalarına ve küçük bir çalışma alanı için baraj yerleşimi için CBS-AHP yaklaşımının değerlendirilmesine katkıda bulunmaktadır.

Optimizing Mini Dam Placement for Sustainable Water Management in FUTA: A GIS-MCDA Approach

Abstract

Addressing the increasing demand for water resources at the Federal University of Technology, Akure (FUTA) due to the growing population requires a data-driven solution. This study determined the suitable locations for the siting of mini-dams as an alternative solution to the problem of water scarcity in FUTA using a Geographical Information Systems (GIS)-based Multi-Criteria Decision Analysis (MCDA) approach by integrating five thematic factors: drainage density, slope, elevation, land cover and soil texture. Preference values were assigned to the criteria based on their importance to a dam. Analytical Hierarchy Process (AHP) was used to assign weights to these criteria, and they were combined using a weighted sum to produce a mini dam suitability map within the study area. The suitable areas were divided into five classes: highly suitable (9%), suitable (18%), marginally suitable (30%), least suitable (26%) and not suitable (17%). The suitability map was validated against the locations of existing dams in the study area. This study contributes to the efforts to manage water resources for a growing population in FUTA and to evaluate the GIS-AHP approach for dam siting for a small study area.
