Yapay Sinir Ağları Kullanılarak Yer Altı ve Yüzey Sularındaki Nitrat Tahmininin Modellenmesi

Bu çalışmada, Devlet Su İşleri Genel Müdürlüğü tarafından Yeşilırmak Havzasında (Amasya) belirlenen istasyonlardaki Nitrat değişim miktarının yüzey ve yeraltı sularının Yapay Sinir Ağları (YSA) kullanılarak tahmin edilmesi amaçlanmıştır. Çalışma 2010 yılları arasında Yeşilırmak Havzasındaki 30 istasyonda (9 yer altı suları, 18 yüzey suları ve 3 kapalı su kaynağı) ölçülen veriler ile yürütülmüştür. Nitrat miktarı 0,341 ila 77,700 mg l-1 arasında olup ortalama nitrat miktarı 17.870 mg l-1’dir. İl Tarım Müdürlüğü tarafından belirlenen havzadaki yeraltı suyu ve yüzey suyundaki nitrat içeriği kullanılarak Amasya'da nitrat miktarındaki değişiklikler Yapay Sinir Ağları (ANNs) temelli bir yaklaşımla sunulmuş ve 2020 ve 2030 yıllarına ait nitrat değerleri tahmin etmiştir. Yapılan modellemede, 30 istasyondaki su kaynağından elde edilen su numunelerinin nitrat seviyeleri, insan tüketimine yönelik Uluslararası ve Türk sınırların altında bulunmuştur.

Modelling Nitrate Prediction of Groundwater and Surface Water Using Artificial Neural Networks

This study aims to estimate the changes in the amount of nitrate in Yeşilırmak Watershed using surface water and underground water of the nitrate content determined by General Directorate of State Hydraulic Works using Artificial Neural Networks (ANNs). This study was conducted in 2010 at 30 stations (9 groundwater, 18 surface water and 3 closed water source) in Yeşilırmak Watershed. Nitrate ranged from 0.341 to 77.700 mg/L, with an average value of 17.870 mg/L. In this study, changes in the amount of nitrate in Amasya using groundwater and surface water in the basin of the nitrate content determined by the Provincial Directorate of Agriculture modeling was presented with an approach based on Artificial Neural Networks (ANNs) and predict the nitrate value for the year of 2020 and 2030. Thus, the nitrate levels of water samples obtained from 30 stations water supplies found to be under the limits of Turkish and international codex of drinking water intended for human consumption.
