Basin models are fundamental for water resources assessment, analyzing quality and quantity of streamflow, managing water distribution systems, protecting and developing groundwater systems, flood protection, and water-supply forecasting. The integration of all hydrologic processes with their interconnections to each other at the basin scale is required for basin models. Mathematical basin models such as HEC-HMS are used for simulating hydrological processes in basin-scale to understand basin response to storm events. The goal of this study is to test the applicability of the HEC-HMS model for a basin located in Turkey and to demonstrate the importance of snowmelt especially for snow affected areas, such as Çakıt Basin which is the study area of this thesis. Requirements of event-based and continuous simulations are identified to guide future HEC-HMS applications in Turkey. Çakıt Basin, which is located in Niğde province has a drainage area of 518 km2. Meteorological data, flow data, digital elevation model, land use/land cover map and soil properties are collected and used in building event-based and continuous models. The models are calibrated and validated with observation stations constructed within the scope of 115Y041 TUBITAK project. The results of this study showed that streamflow at Çakıt Stream Gage Station, both for event-based and continuous runs, can be estimated realistically with NSE values higher than 0.6 for the validation periods using HEC-HMS. Furthermore, the importance of integration of the snowmelt into the hydrologic models is demonstrated.

Application of the bentix index in assessing ecological quality of hard substrata: a case study from the Bosphorus Strait, Turkey
KALKAN, E.; KARHAN, S.U.; MUTLU, E.; SIMBOURA, N.; BEKOLET, M. (National Documentation Centre (EKT), 2007-6-1)
In this paper, a biotic index (Bentix) has been used for the assessment of ecological quality status of shallow water hard substrate benthic ecosystems affected by coastal sewage discharges in the Bosphorus Strait. A significant difference was observed between the control and the discharge stations with regard to Bentix values (Mann-Whitney U Test, p=0.002) and ecological quality status of the discharge stations was worse than that of controls. The index values revealed that sewage discharges caused ser...
Optimization of Multireservoir Systems by Genetic Algorithm
Hinçal, Onur; Altan Sakarya, Ayşe Burcu; Ger, A. Metin (2011-03-01)
Application of optimization techniques for determining the optimal operating policy of reservoirs is a major issue in water resources planning and management. As an optimization Genetic Algorithm, ruled by evolution techniques, have become popular in diversified fields of science. The main aim of this study is to explore the efficiency and effectiveness of genetic algorithm in optimization of multi-reservoirs. A computer code has been constructed for this purpose and verified by means of a reference problem...
Estimation of river flow by artificial neural networks and identification of input vectors susceptible to producing unreliable flow estimates
Kentel Erdoğan, Elçin (Elsevier BV, 2009-09-15)
Reliable river flow estimates are crucial for appropriate water resources planning and management. River flow forecasting can be conducted by conceptual or physical models, or data-driven black box models. Development of physically-based models requires an understanding of ail the physical processes which impact a natural process and the interactions among them. Since identification of the relationships among these physical processes is very difficult, data-driven approaches have recently been utilized in h...
Investigation of the groundwater modelling component of the Integrated Water Flow Model (IWFM)
Ercan, Ali; Dogrul, Emin C.; Kadir, Tariq N. (2016-01-01)
The Integrated Water Flow Model (IWFM), developed by the California Department of Water Resources, is an integrated hydrological model that simulates key flow processes including groundwater flows, streamflow, stream-aquifer interactions, rainfall-runoff and infiltration. It also simulates the agricultural water demand as a function of soil, crop and climatic characteristics, as well as irrigation practices, and allows the user to meet these demands through pumping and stream diversions. This study investig...
Estimation of hydrologic parameters of Kocanaz watershed by a hydrologic model
Akay, Hüseyin; Baduna Koçyiğit, Müsteyde; Yanmaz, Ali Melih (2017-01-01)
The main goal of this study is to estimate the hydrologic parameters of Kocanaz watershed located in Western Black Sea Region, using a semi-distributed hydrologic model, Hydrologic Engineering Center – Hydrologic Modelling System (HEC-HMS). In this study, the hydrologic model was set up for two flood events occurred in 2002 and 2013, in which one was used for calibration while the other one was used for validation of the calibrated hydrologic parameters. The watershed was introduced into the model as a sing...
