Abstract

This study provided methods and methodologies in compliance with the national
legislations that will ensure proper management of groundwater in terms of both
quality and quantity. The methodologies developed in this manner were implemented
in the Gediz River Basin in Turkey. A total of 76 groundwater bodies delineated
in the Basin were subjected to characterization, where the anthropogenic
pressures on the quality and quantity of groundwater and their possible impacts
were determined. Detailed risk analysis done by the available data revealed to the
groundwater bodies which were under risk of achieving good status in terms of
quality and/or quantity. In order to disclose the current status of all
groundwater bodies, in-depth analyses (establishing threshold values,
comparison of the measured values to the threshold values/quality standards,
water budget calculations, etc.) were performed and supported by the
comprehensive field investigations and monitoring. Ultimate results indicated
that 33 groundwater bodies out of 76 were in poor status; and hence, all these bodies
should be included in the programme of measures. Moreover, all the monitoring
points at which the threshold values and/or quality standards are exceeded were
also included in the programme of measures. Finally, the required measures to
be taken in the Gediz River Basin at different scales (basin, groundwater body
and monitoring point); to improve the poor status or to conserve the good
status of groundwater, were pointed out considering both its quality and
quantity.

Yeraltı Suyunun Kalite ve Miktar Bakımından Yönetimi: Gediz Nehir Havzası Örnek Çalışması

Abstract

Bu çalışma, hem nitelik hem de nicelik bakımından yeraltı sularının doğru yönetimini sağlayacak yasal düzenlemelere uygun yöntem ve metodolojiler sunmaktadır. Bu kapsamda geliştirilen yöntemler Gediz Nehir Havzası’nda (Türkiye) uygulanmıştır. Gediz Nehir Havzası için belirlenen 76 yeraltı suyu kütlesi, kalite ve miktar bakımından antropojenik baskılar ile bunların olası etkilerinin belirlendiği karakterizasyona tabi tutulmuştur. Mevcut verilerle yürütülen ve konservatif yaklaşımları benimseyen ayrıntılı risk analizi ile miktar ve kalite bakımından iyi bir duruma gelme riski altındaki yeraltı sıuyu kütleleri belirlenmiştir. Tüm yeraltı sularının mevcut durumunu ortaya çıkarmak için kapsamlı saha araştırmaları ve izleme sonuçları ile de desteklenen derinlemesine analizler (eşik değerlerin belirlenmesi, ölçülen değerlerin eşik değer/kalite standartları ile karşılaştırılması, su bütçesi hesaplamaları, vb.) gerçekleştirilmiştir. Nihai sonuçlar, 33 yeraltı suyu kütlesinin genel durumunun zayıf olduğunu ve dolayısıyla bunların tedbirler programına dahil edilmesi gerektiğini göstermiştir. Ayrıca, eşik değerler ve/veya kalite standartlarının aşıldığı tüm izleme noktaları da tedbirler programına dahil edilmiştir. Son olarak bu çalışma kapsamında, Gediz Nehir Havzası için farklı ölçeklerde (havza, yeraltı suyu kütlesi ve izleme noktası) tedbirler önerilmiş; zayıf durumun iyileştirilmesi veya iyi durumdaki yeraltı sularının statüsünün korunması için miktar ve kalite bakımından alınması gerekli tedbirler belirtilmiştir. yeraltı suyu yönetimi
