Abstract

Flood routing is
the calculation of the change of current (flow, velocity, etc.) values of the
flood wave at any point along a reservoir or channel over time. In terms of
flood control, flood offset calculations have many benefits. The most prominent
of these is that when the flood sizes of the river are known, the flood
hydrographs in a section down the kilometers of this section can be predicted
for hours. In this way, the time required to save lives and property and to
minimize flood damages is reduced and consequently flood damages are reduced.

 

In this study,
flood routing study was performed by using hourly flow data of flood occurred
in in Seyhan Basin of Adana Province. One-hour intermittent hydrograph data
were used at the E18A025 Stream
Observation Station (SOS) on the river and at the D18A054 SOS at 5,044 km
downstream.

 

While the models
were installed, excel program was used in all and calculations and graphics
were created in excel program. Measured values were compared with hydrological
and hydraulic models. The slope of the stations and the distance between the
two stations used in the flood routing methods were utilized from the DSI's
online web page. The measured values ​​of these stations and the results of
hydrological and hydraulic models were compared. During this study, Muskingum
and SCS as hydrological models and Kinematic Wave, Muskingum-Cunge and Dynamic
methods as hydraulicmodels have been applied. While performing this comparison,
the values ​​of Mean Absolute Error (MAE), Root Mean Square Error (RMSE) and
Determination Coefficient (R²) values ​​were calculated and the
performance of the methods were evaluated to determine which method yields the
best results.

 

Since the MAE and
RMSE error values of Muskingum Method are small and R² value is
large, it is seen that this method is the best method in the investigated
basin. Since the error values of Muskingum-Cunge, SCS and Kinematic Methods are
acceptable and the coefficients of determination are quite high, it can be said
that these methods also give good results. The results of the Dynamic Method
were unacceptably unsuccessful due to both high error and low certainty
coefficients.

 

As a result of
the study, it has been determined that Muskingum Method gives the best
estimation, Muskingum-Cunge, SCS and Kinematic Methods predictions are
acceptable, and and Dynamic Method give inaccurate estimates. Only the input
and output hydrograph data are sufficient to establish the Muskingum Method.
Kinematic, Muskingum Cunge and Dynamic Methods for the establishment of the
base slope, roughness coefficient, SOS sections, such as the need for a lot of
data, in terms of reaching the correct result, Muskingum method is considered
to be preferred in the flood routing studies.

ADANA İLİ KARAİSALI İLÇESİ SEYHAN HAVZASI’NDA TAŞKIN ÖTELENMESİ YÖNTEMLERİNİN KARŞILAŞTIRILMASI VE ANALİZİ

Abstract

Bu çalışmada, Adana İli Seyhan Havzası’nda meydana
gelen taşkına ait saatlik debi verileri kullanılarak taşkın ötelenme çalışması
yapılmıştır. Akarsu üzerindeki E18A025 nolu Akım Gözlem İstasyonu'nda (AGİ) ve
bu AGİ'nun 5,044 km mansabında yer alan D18A054 nolu AGİ'nda gözlenen birer
saat aralıklı hidrograf verileri kullanılmıştır. İstasyonlarda ölçülen değerler
ile hidrolik ve hidrolojik modellerin sonuçları karşılaştırılmıştır. Çalışmada
hidrolojik modellerden Muskingum ve SCS; hidrolik modeller olarak da Kinematik
Dalga, Muskingum-Cunge ve Dinamik yöntemleri uygulanmıştır. Ölçülen ve
modellerden hesaplanan değerler arasındaki Hataların Ortalama Karekökü (HOK),
Ortalama Mutlak Hata (OMH) ve Belirlilik Katsayısı (R²) değerleri
hesaplanmış ve yöntemlerin performansları irdelenerek hangi yöntemin daha iyi
sonuç verdiği değerlendirilmiştir.
Çalışma sonunda, Muskingum Yönteminin en iyi tahmini verdiği, Muskingum-Cunge, SCS
ve Kinematik Yöntemlerinin tahminlerinin de kabul edilebilecek düzeyde olduğu,
Dinamik Yöntemin ise oldukça hatalı tahminler verdiği belirlenmiştir.
