This report describes the application of the long and short terms runoff model（LST-II), which is developed by Kadoya and Nagai（1988）for analyzing both flood and long term runoff successively, to consider the effects of the land use form in the runoff process. The three type models are considered to introduce the the effects of non-uniformmity in the infiltration phenomina at top layer zone of slope system. The first attempt is discussed by runoff model I,II, in which infiltration capasity at the ground surface is limitted to a constant value or a same form of Horton curve induced by the change of subsurface condition. The third type of the modified LST-II model, runoff model III, is proposed to express the effects of distribution of permeable area and impermeable one in the basin. The impermeable area is developed by urbanization in a residental district and integrated rural improvement. In the runoff model III, the upper zone of first tank is divided two parts by the ratio of permeable area and impermeable one in the basin. The left part expresses the impermeabl field to occure surface runnoff easily. And the right one assigns the permeable field to arise both of surface runnoff and subsurface one. These three runoff model is adapted to the experimental basin at land reclamation area in Masuda City. The runoff model I, II results almostly the same reproducibility of the observed hydrograph comparing the LST-II model. While, it is shown that the analysis by runoff model III improves the reproducibility of the peak discharge in observed hydrograph about 9％ than the LST-II model. 自然丘陵山地の部分開発域あるいはスプロール的に混住化社会が進展する農村地帯等を含む地域を対象に流出特性を検討する際，その流域の地形・土地利用形態に応じた分布型の流域モデルを設定し，雨水流モデルに代表される，いわゆる分布定数型流出モデルによる解析が望まれる．一方，菅原タンクモデル，貯留関数法，長短期流出両用モデル等の貯留型流出モデルは，斜面流，河道流を区別することなく流出過程を極端に集中化したモデルであるから，雨水流モデルならば説明できるはずのいくつかの現象が説明できなくなる欠点を持っているといえる．したがって，自然丘陵山地の部分開発域等を含む流域に貯留型流出モデルを適用する際，流域の都市化現象と類似のいくつかの地文条件及び水文条件の変化をどのように流出モデルに組入れるかが課題となる．本報告では，開発地域にみられるような舗装道路面積や水路網の具備の効果，あるいは地表条件の面積的な分布の効果を貯留型流出モデルによる流出解析に取入れることを目的に、長短期流出両用モデルを活用した手法でこうした課題への試みを意図して行った若干の検討例について述べる．

斐伊川から宍道湖へ流出する汚濁負荷量の推定

The runoff loads of pollutants such as nitrogen, phosphorus and COD in River Hii were estimated for 3 years from the weekly sampling data collected at the middle stream point (Kisuki) and the downstream point (Otsu) by using the L-Q equations. The annual runoff loads varied widely for the three years, because there were large differences in the amount of precipitation (from 1,308mm/y to 2,307mm/y) and runoff discharge. The largest annual loads at the downstream point for T-N, T-P and T-COD were calculated to be 1,090ton/y, 49.6ton/y and 3,290ton/y, respectively, whereas the smallest loads for T-N, T-P and T-COD were 483ton/y, 22.8ton/y and 1,530ton/y, respectively. The loads at the middle stream point were estimated to be about half of the loads at the downstream point.

水文環境の変化に伴う流出形態の変化予測のための流出モデルの開発

福島晟, 武田育郎, 森也寸志

島根大学農学部研究報告 29 23 - 29 1995年12月

記述言語：日本語出版者・発行元：島根大学

A new runoff model is developed for runoff analysis，which is applicable to discuss the effects of global warming on the hydrological cycle and analyze a runoff phenomena considering the regional distnbution of rainfall amount in a river basin. The following results are obtained: 1）The runoff model is combined kinematic wave runoff model with the Long and Short Terms Runoff Model(LST-IIModel). Namely, the upper zone of the model is composed by kinematic wave model and the lower zone of one is the same with the LST-IIModel. 2）The effective rainfall concerned in the surface runoff and/or prompt subsurface runoff is automatically computed in KiWS Model II. 3）The routine phases of rainwater flow on hillslope and stream flow in stream network are expressed by the kinematic wave model，in which the effective rainfall series corresponding to the regional distribution of rainfall amount are given as input condition for each basin block. 4）A runoff simulation shows that the KiWS ModelII is applicable as a runoff model considering the regional distribution of rainfall amount in a river basin.
