APPLICATION OF A CONCEPTUAL WATER BUDGET MODEL FOR SALDA LAKE, (BURDUR/ TURKEY)

Abstract

Sustainable water resources management is a priority issue today. One of the major problems in the sustainable usage of lakes is the estimation of water budget components. The determination of the water budget of lakes is fundamental to an understanding of their hydrological characteristics. The Salda Lake is an inland closed basin and located within the Lake District of Turkey. In addition, the Salda Lake is one of the important wetlands of Turkey and is in the status of protected areas. Therefore, the Salda Lake is indispensable water source for region. The Salda Lake area is 44.7 km2 and lake level is 1136.5 m. In this study, conceptual water balance model of the Salda Lake was developed. Recharge of the Salda Lake is supplied from especially precipitation, surface and groundwater inflow. The directly recharge from the precipitation was calculated as 22.04 (x106) m3/year. The discharge components of the lake are evaporation. The evaporation amount from the lake was determined as 53.98 (x106) m3/year. The unmeasured recharge from groundwater was calculated as 26.33 (x106) m3/year. According to rainfall, evaporation and the lake water level relations, rainfall is dominantly effective on the lake water level change.

SALDA GÖLÜ İÇİN KAVRAMSAL SU BÜTÇE MODELİNİN UYGULANMASI, (BURDUR/TÜRKİYE)

Abstract

Sürdürülebilir su kaynakları yönetimi bugün öncelikli bir konudur. Göllerin sürdürülebilir kullanımındaki en büyük sorunlardan biri, su bütçesi bileşenlerinin tahmin edilmesidir. Göllerin su bütçesinin belirlenmesi, hidrolojik özelliklerinin anlaşılması için önemlidir. Salda Gölü, kapalı bir havza olup, Türkiye'nin Göller Bölgesi'nde yer almaktadır. Ayrıca, Salda Gölü Türkiye'nin önemli sulak alanlarından ve korunan alanlarından biridir. Bu nedenle, Salda Gölü bölge için sürdürülebilir yönetimi önemli bir su kaynağıdır. Salda Gölü’nün alanı 44.7 km2, göl seviyesi 1136.5 m dir. Bu çalışmada Salda Gölü için kavramsal su denge modeli geliştirilmiştir. Salda Gölü’nün beslenimi, özellikle yağış, yüzey ve yeraltı suyu akışından sağlanmaktadır. Salda Gölü için yağıştan besleme 22.04 (x106) m3/yıl olarak hesaplanmıştır. Gölün en önemli boşalım bileşeni buharlaşmadır. Gölün buharlaşma miktarı 53.98 (x106) m3/yıl olarak belirlenmiştir. Yeraltısuyundan ölçülmeyen beslenim miktarı ise 26.33 (x106) m3/yıl olarak hesaplanmıştır. Yağış, buharlaşma ve göl su seviyesi ilişkilerine göre, çalışma alanı için yağış, göl su seviyesi değişiminde baskın bileşendir.
