It is well -known that sediment causes the variation of configuration of stream bed, the decrement of the reservoir storage capacity and the amount of power out-put, the failure of hydraulic structures, and the shortage of the amount of water available for use. It is a important factor to determine the rate of sediment transportation in the stream, when development projects are to be planned also to be deviced for controlling sediment. The data is obtained at Sangye station in Geum river system and is analysied by the H.A Einstein, Kalineske, Du Boys and Garde-Albertson formulas. The results is noted that estimated values by Kalineske formular shows corresponding well with field data. Therefore it will be feasible to do use Kalineske formula for the calculation of sediment quantity in small system. It effects on the development of water resources at small stream in the future.

A comparative study with adjacent areas appears to be necessary in order to understand the early agriculture of the Korean Peninsula and its diffusion to the Japanese Archipelago. Thus this research aims to establish a dataset of literature related to early agriculture in the Shandong and Jiangsu provinces. Firstly, data concerning the archaeological sites of the Jiangsu and Shandong province areas are collected. Although Zhejiang province has also yielded many early rice agriculture sites, such as the famous Hemudu site, the nature of the sites in this region appears to be broadly similar to that of Jiangsu province. Literature data from published reports are classified based on the locality and time period of the site, with a supplementary dataset including the results of phytolith analysis and flotation. Rice had been the sole crop cultivated in Jiangsu province since 5000 BCE whereas changes in crop assemblages over time can be observed in Shandong province. Millets were the main crops from the Hui to Zhou dynasty periods, but rice cultivation became the main mode of subsistence in the Yongshan period. Rice cultivation appears to have been favoured due to the wetter and warmer climate of the time, which benefited rice production. After the Yongshan period, wheat replaced rice to became the main crop from that time onwards. The collapse of the Yongshan culture appears to have been caused by climatic change and it was replaced by the less advanced Yueshi culture, triggering mass migration. Immigration movements following the fall of the Yongsan culture occurred in the adjacent pan-West Sea area and may have influenced the agricultural mode of Liaoning province and the Korean Peninsula. Influx of migration groups with notched raised band (gakmokdoldaemun) pottery into the Korean Peninsula and the fact that rice came to be cultivated may be seen to reflect the gradual cultural diffusion of rice agriculture in this region.
