Abstract

In this study, it was aimed to investigate applicability of various statistical estimation methods for Porsuk River basin, which has sparse streamflow observations. Estimations were performed using regression, single and multiple donor stations based drainage area ratio, standardization with mean (SM), standardization with mean and standard deviation (SMS), inverse distance weighted methods. Two seperate studies were conducted for both partially missing data and completely missing data. In order to estimate streamflow statistics for use in SM and SMS methods, logarithmic regression equations were suggested. The promising results obtained from ensemble approaches will provide a significant hydrological contribution to streamflow estimations.

估算缺失日流量数据的统计方法评价

本研究旨在探讨各种统计估计方法在波苏克河流域的适用性，该流域具有稀疏的流量观测。采用回归、基于单、多供体站的排水面积比、均数标准化(SM)、均数和标准差标准化(SMS)、逆距离加权等方法进行估算。对部分缺失数据和完全缺失数据分别进行了两项独立的研究。为了估计SM和SMS方法中使用的流量统计量，提出了对数回归方程。从集合方法获得的有希望的结果将为流量估算提供重要的水文贡献。

期刊介绍： The scope of Teknik Dergi is naturally confined with the subjects falling in the area of civil engineering. However, the area of civil engineering has recently been significantly enlarged, even the definition of civil engineering has somewhat changed. Half a century ago, engineering was simply defined as “the art of using and converting the natural resources for the benefit of the mankind”. Today, the same objective is expected to be realised (i) by complying with the desire and expectations of the people concerned and (ii) without wasting the resources and within the sustainability principles. This change has required an interaction between engineering and social and administrative sciences. Some subjects at the borderline between civil engineering and social and administrative sciences have consequently been included in the area of civil engineering. Teknik Dergi defines its scope in line with this understanding. However, it requires the papers falling in the borderline to have a significant component of civil engineering.
