The stream physiographic characteristics of a watershed have important influence upon the analysis of run off. In this study, the applicability of the Horton's law of stream number, average stream length, average stream slope, was investigated with the data taken from photographic maps(1:25,000) which cover the whole MiHo River basin. As the result of this study I reached the conclusion that the MiHo River system was developed very closely by Horton's law and that was found to have reached closely old stage. The other wise, the concept of proportional stream ordering system was employed to describe continuously the longitudinal variation of the stream morphological characteristics.

The stream morphological characteristics of watershed have important influence upon the analysis or runoff. In this study, the, effect of the map scale on the stream morphological characteristics was used on the data taken from 15'(1:50,000) and 7'30$quot;(1:25,000) topographic maps which could cover the whole Miho River basin, This basin are the first tributary of the Geum River, Otherwise, the longitudinal stream bed profile was calculated by Yang's theoretical stream bed profile, equilibrium profile and actual profile. In the result of this investigation the conclusion is that the resultant relationship obtained from different topographic maps in the scale on the same stream system has come upon the same result as the stream morphological characteristics. Therefore, the great amount of time and effort can be saved in studing the stream morphological charecteristics by using the 15' instead of the 7'30$quot; map system excluding the first order streams.

This study is a water-analysis compareing the water samples from mineral water spring in Chung-Ju area ( Nam San, Tan Kum Dae, Anlim Dong, Nam San temple ) with the standard of water supply in Korea. The results obtained are as follows ; It has been shown that the value in P.P.M. from the water-analysis for other substances than tubidity and nitrite nitrogen only falls shorts of the range of standard of water quality for water supply in Korea. Among the above-mentioned four kinds of mineral water, it has been shown that mineral water spring of Nam San temple contains the best kind of mineral in it's quality and quantity.

This study was performed to investigate of substrate characteristic of COD for piggery wastewater of nutrient(nitrogen and phosphorus) removal. The influent COD of the piggery wastewater is divided into readily biodegradable COD(Ss) , slowly biodegradable COD (Xs), inert soluble COD(SI) and inert suspended COD(XI). Percents of each form were resulted as 36.6%, 29.7%, 7.7%, and 27%, respectively. The ammonia nitrogen was utilized via stripping, nitrification, autotrophic cell synthesis, heterotrophic cell synthesis, and aerobic denitrification. The removal percents by each step were resulted as 12.9%, 43.1%, 15%, 3.2% and 25.7%, respectively.

Generally, in order to increase of removel effciency in BNR(Biological Nutrient Removal) system, the analysis of charateristics in subtrate is very important. The object of this study was to analysis organic and nutrient substrate of piggery wastewater for BNR system. The results obtained in this study were summarized as follows; The influent COD of the piggery wastewater is divided into readily biodegradable COD(Ss), slowly biodegradable COD(Xs), inter soluble COD(Sr) and inert suspended COD(Xl). Percents of each from were 36.6%, 29.7%, 7.7%, and 27%, respectively.

This research was carried out for the effects of large-scale hot spring development on water quality. The Shin-Wul stream, which runs into the Dalchun river, was the object of this study. The water of Shin-wul stream was analyzed seasonally for one year from August, 1987 to August, 1988. The former data were also used. The collected data were input into the QUAL2E-H program, a Model which estimates water Quality. The result was as follows: Even if more than 90% of organics produced by the hot springs were eliminated, the quality of water was still deteriorated. This rendered the water unfit for drinking and agricultral use.

This is a study on the measurement about the transpiration of plants. In order to measure the transpiration, it was necessary to manufacture the phytometer. In this phytometer 12 different kinds of plants were cultivated and the transpiration of these plants was measured from march. 1985 to July, 1985. As a result, the coefficient of consumptive amount about the 12kinds of plants was researched and obtained.
