“…GIS and Remote sensing techniques Geographic Information system (GIS) is computer based system that provides capabilities for input, data management, data storage and retrieval, manipulation, analysis and output to handle spatial data (Aronoff, 1995;Bhatt,et al, 1995). GIS technology is essential in the hazard and flood related problems which support surface water modeling and flood hazard exposure (Boyle et al, 1998;Greene & Cruise, 1995;Paudyal). GIS and remote sensing focus on delineation of flood zones, preparation of flood hazard and risk maps .…”

“…In addition, a tool was developed for further incorporating the GIS spatial analysis into the hydrologic analysis of an urban watershed 32) . The change of land use in a single lot with a city block corresponding to the nearest storm drain was defined through urban storm watershed modeling 33) . These methods can be effective for developing countries, in which the urban flooding associated with surface and subsurface drainage systems is the main urban watershed management issue.…”

“…Though the applied data are different in scales and resolution, this shortcoming can be minimized through selection of the data sources with minimal scale differences, with the exception of soil maps. However, this method still has some limitations, including digital format availability 33) . These limitations are even more significant in developing countries, where digital data are less available.…”

With increased awareness of the importance of land use change at both local and regional scales within watershed-based planning, the study of land use analysis has become the focus of several international scientific endeavors. Since land use change has become a major issue in this century due to global urbanization, the study of watershed-based land use analysis will play an important role in a sustainable future. This paper undertakes a comprehensive review of watershed-based land use analysis to clarify the research trends in this area, including basic tools, factors, methodologies, study regions, scales and areas. Land use detection methods, land use modeling and thresholds in watershed delineation were identified as the fundamental tools, while land use policies, water quality, surface runoff, flooding control, land use suitability and land allocation analysis, and landscape structure were identified as the main factors in watershed-based land use planning.

“…Su kalitesi belirlenerek, kirlilik unsurları tespit edilip, minimum düzeye indirilmesi için gerekli önlemlerin alınması sağlanmalıdır [3]. Su kaynaklarının korunması, geliştirilmesi ve yönetimi çalışmalarında bilgisayar destekli veri analizi ve görselleştirme araçları, istatistik yöntemler ve özellikle coğrafi bilgi sistemi (CBS) öncelikli teknoloji durumuna yükselmiş ve son yıllarda CBS tabanlı su kalitesi yönetim sistemleri yaygın biçimde kullanılmaya başlanmıştır [4][5][6][7][8][9]. Yapılan bu çalışmada; Aksaray ilinin içme ve sulama ihtiyacını karşılamakta olan Mamasın Barajı yüzey suyu kalitesine yönelik olarak toplam 16 adet ölçüm istasyonundan mevsimsel olarak alınan örneklerde analizler yapılmış, CBS ile konumsal analizi ve tematik haritalandırılması yapılmıştır.…”

ÖZBu çalışmanın amacı; Aksaray İlinin içme-kullanma ve sulama suyu ihtiyacını karşılayan Mamasın Baraj Gölü su kalitesinin mevcut durumunu tespit etmek ve konumsal olarak olası kirlenmenin boyutlarını ortaya çıkarmaktır. Araştırma kapsamında 2015 yılında 16 adet ölçüm istasyonu için; ıslak dönem (Şubat, Mart, Nisan ve Mayıs aylarında) ve kuru dönem (Haziran, Temmuz, Ağustos ve Eylül aylarında) olmak üzere numuneler alınarak örnekleme yapılmıştır. Yüzeyden örneklenen tüm su numunelerinde; çözünmüş oksijen, sıcaklık, pH, elektriksel iletkenlik, toplam çözünmüş katı madde, nitrat (NO 3 -) ve sülfat (SO 4 -2 ) kalite parametreleri için yerinde ve laboratuvar koşullarında analizler yapılmıştır. Tespit edilen tüm sonuçlar için coğrafi bilgi sistemi ile baraj suyu kalitesi konumsal olarak değerlendirilmiştir. Çalışma kapsamında analiz edilen genel kimyasal ve fizikokimyasal parametreler bazında baraj gölü yüzey suyunun mevcut önlemlere rağmen 1. sınıf su kalitesini koruyamadığı tespit edilmiştir.Anahtar Kelimeler: Mamasın Barajı, su kalitesi, coğrafi bilgi sistemi, Aksaray EVALUATION OF SURFACE WATER QUALITY OF MAMASIN RESERVOIR BY USING GEOGRAPHICAL INFORMATION SYSTEM (GIS) ABSTRACTThe main purpose of this study are to determine the current situation of water quality in Mamasın Dam Lake which meets the drinking-using and irrigation water need of Aksaray city, and to present the dimensions of spatial pollution. Within the scope of this research, the sampling was carried out by taking samples in wet period (February, March, April and May) and dry period (June, July, August and September) from 16 monitoring stations in 2015. In all water samples taken from the surface, the analysis was carried out for quality parameters of dissolved oxygen, temperature, pH, electrical conductivity, total dissolved solids, nitrate (NO 3 -) and sulphate (SO 4 2-) in situ and at laboratory conditions. The reservoir water quality was spatially evaluated by using geographical information system for all determined results. Within the scope of the research, it was determined that dam lake surface water unprotected its 1 st class water quality despite of precautions for all analysed chemical and physicochemical parameters.
