A reliable model for the practical use will be obtained from detailed basin studies. The capability of a distributed storage model which is derived from the histori cal view of model building is described here, and its application to the practical problems in water management is discussed. It is shown that the simultaneous computation of long-term and short-term runoff is useful for the estimation of a design flood and for flood forecasting. The runoff processes which must be clarified in basin studies are described according to such model applications. The need for of research basins in developing useful models and realizing the rational water management is stressed through a brief sketch of recent basin studies in Europe, where there is a long history of hydrological studies.","PeriodicalId":137099,"journal":{"name":"Journal of irrigation engineering and rural planning","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116897092","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From the viewpoint of agricultural engineering, it is necessary to expedite farmland consolidation works as well as to reclaim new farmland so as to increase agricultural output by means of improvement of productivity of land and labor. In this paper, the characteristics and problems of farmland consolidation in Japan are discussed based on the relation of agricultural land improvement projects to rural development, taking present land use and the supply and demand situation of food into consideration.","PeriodicalId":137099,"journal":{"name":"Journal of irrigation engineering and rural planning","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116746283","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On-farm water management practice in Japan has reached the level where water can be managed for optimum rice production. The optimum management of plot water depth for high yielding rice has been given top priority in daily on-farm water management operations. Static on-farm water management practice is still dominant in the Tanjung Karang Irrigation Scheme. Stability of water supply and the improvement of on-farm infrastructure are vital to encourage farmers to adopt better on-farm water management practice.","PeriodicalId":137099,"journal":{"name":"Journal of irrigation engineering and rural planning","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115635727","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Light is being shed on the structural adjustments of agricultural production, and the quality of life in rural areas has started to receive more and more attention. A project is undertaken by either the national or a local government based on farmers' initiative, or by the farmers thermselves. Implementation is commenced upon the completion of legal procedures with the Ministry of Agriculture, Forestry and Fisheries as stipulated by the Land Improvement Law. Every project is subsidized by the national and/or local governments, but the actual percentage of subsidy varies with the size of the benefited area and the category of the project. An unsubsidized portion of the project cost is to be borne by the participating farmers. If the project is executed by the national government, the government provides all the funds for the construction, and the farmers repay their share upon the completion of the project. For the past 3 or 4 years, annual budget authorization for land and water resources development for agriculture has accounted for about 2% of the total amount of the national budget, an amount equivalent to about 1/4 of the entire budget of the Ministry of Agriculture, Forestry and Fisheries.","PeriodicalId":137099,"journal":{"name":"Journal of irrigation engineering and rural planning","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114479717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, one of the nation's most serious problems is the lack of farm land . The low rate of land consolidation also means that efforts to food self-sufficiency are insufficient . In order to increase the economical potentiality in the district, there is a strong demand for development and improvement of agricultural land. In Chugoku and Shikoku districts, where the percentages of the mountainous and hilly areas are extremely high, extensive development work has been begun by government . But owing to the unfavorable conditions of topography , geology and climate, there are many factors working against these projects. (1) Environmental changes: Large amounts of earth work brought by topographical improvement cause changes in hydrological characteristics and result in environmental transfiguration.(2) Land conservation: A large scale earth work makes destruction of the land easier. Therefore, it is necessary to pay much attention to the incidental facilities especial ly in conservation.(3) Construction cost: Owing to these unfavorable conditions for land development, operation costs are necessarily highly expensive.(4) Structure and its effect on agricultural production: Difference in the direction and inclination of slope cause some differences in the land's climatic conditions, especially in solar radiation . Therefore, in farm land development in mountainous district, structure planning of the field has to be considered .","PeriodicalId":137099,"journal":{"name":"Journal of irrigation engineering and rural planning","volume":"606 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115107198","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
