 note = {From last year, the water gate construction started at the mouth of Nagara River. There are two purposes for the construction of the gate; one is to control the flooding, another is to obtain a water resource. Regarding the former problem, the Water Resources Development Public Corporation, planned to deepen the river bottom in order to expand the area of the river section. But the deepening of the river bottom would lead the flow of much more seawater into the upper stream than at present. The authorities of the above corporation have emphasized the necessity of gate to eliminate the influence of seawater by possible rice field damage due to saline water which might penetrate through the bank. I will discuss the water pollution problems after the construction of gate at the mouth of river., Article, 信州大学理学部付属諏訪臨湖実験所報告 7: 121-128(1991)},
