AHP–TOPSIS–GIS ENTEGRE YAKLAŞIMI KULLANILARAK DARCY YASASI’NA DAYALI YERALTI SUYU AKIŞI MODELLEMESİ: ŞANLIURFA, BİRECİK ÖRNEĞİ

Abstract

Bu çalışmada, Birecik İlçesi'nin (Şanlıurfa, Türkiye) yeraltı suyu akış karakteristikleri, Analitik Hiyerarşi Süreci (AHP) ve TOPSIS'i birleştiren entegre bir GIS tabanlı çok kriterli karar analizi çerçevesi kullanılarak Darcy Yasası temelinde incelenmiştir. Yeraltı suyu akışını etkileyen kavramsal ve hidrolik parametreler, hidrolik yükseklik, etkin yükseklik, hidrolik eğim, hidrolik iletkenlik ve geçirgenlik dahil olmak üzere, Darcy prensiplerine uygun olarak tanımlanmıştır. Hidrolik iletkenlik ve toprak geçirgenliği verileri, GIS ortamında Darcy tabanlı kavramsal bir yeraltı suyu modeli geliştirmek için kullanılmıştır. AHP'den elde edilen kriter ağırlıkları, Darcy akış koşullarının uygunluğunu değerlendirmek için TOPSIS yöntemine entegre edilmiştir. Sonuçlar, çalışma alanında yeraltı suyu akışını kontrol eden en etkili parametrelerin hidrolik eğim, toprak dokusu ve gözenek yapısı olduğunu ve hidrolik eğimin en yüksek AHP ağırlığına (%34) sahip olduğunu göstermektedir. Mekansal analizler, hidrolik iletkenlik ve geçirgenliğin heterojen dağılımını başarıyla ortaya koydu ve model, 0,92'lik bir belirleme katsayısı (R²) ile güçlü bir performans sergiledi. Bu entegre yaklaşım, veri sınırlı bölgelerde Darcy temelli yeraltı suyu akışını değerlendirmek için güvenilir bir çerçeve sağlar.

GROUNDWATER FLOW MODELING BASED ON DARCY’S LAW USING AN INTEGRATED AHP–TOPSIS–GIS APPROACH: A CASE STUDY OF BIRECIK, SANLIURFA

Abstract

In this study, the groundwater flow characteristics of the Birecik District (Şanlıurfa, Turkey) were investigated based on Darcy’s Law using an integrated GIS-based multi-criteria decision analysis framework combining the Analytical Hierarchy Process (AHP) and TOPSIS. Conceptual and hydraulic parameters influencing groundwater flow, including hydraulic head, effective head, hydraulic gradient, hydraulic conductivity, and permeability, were defined in accordance with Darcy’s principles. Hydraulic conductivity and soil permeability data were utilized to develop a Darcy-based conceptual groundwater model within a GIS environment. The criteria weights derived from AHP were integrated into the TOPSIS method to evaluate the suitability of Darcy flow conditions. The results indicate that hydraulic gradient, soil texture, and pore structure are the most influential parameters controlling groundwater flow in the study area, with the hydraulic gradient exhibiting the highest AHP weight (34%). Spatial analyses successfully revealed the heterogeneous distribution of hydraulic conductivity and permeability, and the model demonstrated strong performance with a coefficient of determination (R²) of 0.92. This integrated approach provides a reliable framework for assessing Darcy-based groundwater flow in data-limited regions.
