The characteristics of hydrologic design parameters for small hydro power(SHP) sites located in four major river systems have been studied. The model, which can predict flow duration characteristic of stream, was developed to analyze the variation of inflow. And another model to predict hydrologic performance for SHP plants is established. The results from hydrologic performance analysis for SHP sites located on five major river systems based on the models developed in this study show that the specific design flowrate and specific output of SHP site have large difference between the river systems. The load factor, however, have small difference compared with specific design flowrate and specific output for all river systems. Also, it was found that the models developed in this study can be used to predict the primary design specifications of SSHP plants effectively.

The word "soundscape" proposed by Canadian composer R. Murray Schafer is now became very popular. So various soundscape design based on soundscape idea are carried on worldwide for acoustic ecology. Also in Korea, several soundscape design were made for the public spaces such as river, park and bridge but, basic concept behind soundscape design was not reflected and studied sufficiently. In that sense, this study aims to arrange the concept of soundscape design process and to review the design proposals of Gwangju River. In this process, the reproduction concept of soundscape, natural sound, light with sound, cultural and historical sound and etc. were classified and the final design was proposed to recover the natural environment and harmonize the sound with surroundings as creative soundscape.

Small hydropower resources for five major river systems have been studied. The model, which can predict flow duration characteristic of stream, was developed to analyze the variation of inflow caused from rainfall condition. And another model to predict hydrologic performance for small hydropower(SHP) plants is established. Monthly inflow data measured at Andong dam were analyzed. The predicted results from the developed models in this study show that the data were in good agreement with measured results of long term inflow at Andong dam. It was found that the models developed in this study can be used to predict the available potential and technical potential of SHP sites effectively. Based on the models developed in this study, the hydrologic performance for small hydropower sites located in river systems have been analyzed. The results show that the hydrologic performance characteristics of SHP sites had some difference between the river systems. Especially, the specific design flow and specific output of SHP sites located on North Han river and Nakdong river systems had large difference compared with other river systems.

The correlation between hydrologic performance design parameters of small hydro power(SHP) sites and rainfall condition have been analyzed for major river systems. The model, which can predict flow duration characteristic of stream, was developed to estimate the inflow caused from rainfall. And another model to predict hydrologic performance for SHP plants is established. Based on the models developed in this study, the hydrologic performance characteristics for SHP sites have been analyzed. The results show that the hydrologic performance characteristics of SHP sites have some difference between the river systems. Especially, the specific design flowrate and specific output of SHP sites located on North Han river and Nakdong river systems have large difference compared with other river systems. It was found that the hydrologic performance design parameters such as specific design flowrate and specific output were affected by rainfall condition in basin area of SHP sites.

This study is to secure more accurate data of the discharge on the measurement by gaining a reliable hydrological data through the comparison the present method of measuring them and the other way that is based ISO. This study suggests the applicable measurement method of the discharge that has reliance through general elements and the analysis of uncertainty by comparing and assaying the data of the Hyung San River that is measured by the present standard. The result of this study makes us realize that we should complement the measurement method of the discharge securing the reliable and accurate hydrological data Hydrological data is very important things to perform domestic river works or install some structure in river or coast. Securing reliable and accurate hydro-data and making a thesis should go on in other to do any construction in river or coast.

The river technology of Japan was highly developed and achieved much result in flood protection, water use and the environment. Nowadays, the function which is requested to the river is changes because the society changes from growth to maturity. In this study, we suggest the functions of the river in the maturity society about future welfare, medical care and education based on field research of case study. In this research, we pay attention to the functions related with culture, one) function of healing, mental stress improvement and life, two) function of landscape, education and recreation. And this paper proposed the usage of the river where adopt to the times, a function and the value of "the river as the space". We made a questionnaire to 187 river managers, and 90% of answers wear positive for use the river as the medical aspect, health and the welfare. Furthermore, based on research result of hospitals and welfare facilities which used a river for their activities, we suggest to develop and use the river walk, to design a city and rivers as one, and to use many facilities which are located on river front more active, those are improve the new river functions.

본 연구는 장소성의 개념을 건축공간 계획에 적용하고자 하는 설계연구이다. 본 연구의 계획 대상지는 영국 런던의 템스 강으로 강을 따라 이동하고 필요에 따라 강변에 정박하여 사용할 수 있는 건축물을 계획하는 것이다. 본 연구의 진행은 다음과 같다. 첫째, 장소성과 무장소성, 그리고 비장소성에 대한 이론적 고찰과 템스 강이 갖는 특수한 성격의 장소성을 분석한다. 둘째, 장소와 건축물과의 관계, 건축물의 형태, 그리고 사용자의 행위의 세 가지 관점에서 각각의 계획개념을 계획안에 적용될 수 있는 계획요소로 정리한다. 셋째, 정리된 계획요소를 건축 프로그램으로 구체화하여 최종 결과물로서의 영국 런던의 템스 강에 부유하는 복합문화공간 계획안을 제안한다. 본 연구에서 주목한 것은 건축물의 인식과 건축물을 사용하는 사람들의 행위가 상호보완적으로 장소성을 형성한다는 것으로 본 연구에서 제안하는 계획안은 건축물이 위치하는 템스 강의 물리적, 자연적, 그리고 물질적 특성을 건축물이 최대한 수용할 수 있도록 하여 건축물 그 자체에 의한 장소성이 아니라 은유적으로 표현될 수 있는 내재되어 있는 속성으로서의 장소성을 구현한다는 의미를 갖는다.

국내 3대 하천인 한강, 낙동강, 금강에 대한 조도계수 산정 결과를 바탕으로 FLDWAV 모형과 HEC-RAS 모형을 이용하여 본 연구에서 산정한 조도계수와 기존 하천정비기본계획의 조도계수 그리고 하상토 입경을 이용해 산정한 조도계수를 비교분석하고 적용성을 검토하였다. 두 모형에 적용한 바 본 연구에서 제시하고 있는 조도계수를 이용한 계산 홍수위가 관측치와 매우 잘 일치하였다. 또한 기존 선행연구의 FLDWAV 모형에 의한 조도계수와 다양한 수리특성인자와의 상관관계를 검토한 결과 상관성은 거의 없었다. 끝으로 팔당댐 하류 한강 본류에 대하여 본 연구에서 산정한 조도계수를 이용하여 HEC-2 모형으로 기존 하천정비기본계획의 계획홍수위를 검토하였으며, 기존 제방의 일부가 안전성면에서 미흡한 것으로 나타났다.

To drive efficiently total water pollution load management, needs to calculate the exact load emissions, pollution load allocation and implementation evaluation in each unit area of watershed and accurate and regular flow of data. For these reasons, the Nakdong River TMDL Research Center has produced directly or indirectly in the average interval of eight days (30 times or more / year) 41 points for unit area of the total water pollution load management and 8-point of municipal requirement for a total of 49 branches as a flow data in 2004 from August. This acquired the survey flow is evidence of trends and changes each point in the Nakdong River based on time, such as 10 years based on average design flow available to the foundation of the summit as the major water policy is to be utilized. This study was performed on actual discharge measuring data and introduced performance results each drainage basin of Nakdong River from 2004 to 2008 over the total of past five years.
