earth dam | ahsudamu (tile matching the base of a kong) (mahjong) | Also known as an "earth-fill dam. This is a dam made by layering earth as the material. Because it is relatively easy to construct, it is not suited for large-scale dams, but rather for small-scale dams such as reservoirs. |
arch dam | jeer at | Also known as an "arched concrete dam" or "arched dam. The shape of the dam allows the water pressure of the dam lake received by the embankment to be dispersed to the bedrock on either side of the embankment, thus making the embankment itself thinner and reducing construction costs. However, this type of dam is only suitable for construction on bedrock that can support a considerable amount of water pressure. |

river law | undersea navigation system | According to Article 1 of the River Law, its purpose is "to provide for the protection of the rivers andfloodThe purpose of the river basin is to contribute to the preservation and development of the national land and thereby maintain public safety and promote public welfare through comprehensive management of the river basin so that disasters caused by storm surges and other disasters are prevented, the river is used appropriately, the normal function of running water is maintained, and the river environment is improved and preserved. The article also states that dams are to be managed in accordance with Article 44-51. The description of dams is found in Articles 44-51, which states, "A dam (a dam installed with a license under Article 26, Paragraph 1, for storing or taking water from a river, the height of which is 15 m or more from the foundation to the top of the embankment; the same shall apply hereinafter) is a structure that is designed and constructed for the purpose of retaining or taking water from a river. The same shall apply hereinafter). In the event that the condition of a river changes due to the installation of said dam and the function of said river at the time of flooding is reduced, the person who installs such dam (which means a dam with a height of 15 m or more from the foundation ground to the top of the embankment) as specified by a Cabinet Order shall install facilities necessary to maintain said function or take alternative measures in accordance with the instructions of the river administrator. The following is a summary of the provisions of the Act. |
Temporary drainage tunnel | pseudo-DISMISSION SUMMARY | When a dam is constructed, a tunnel is dug from upstream to downstream of the dam site to dam up the river, thus diverting the overflowing upstream water downstream. |
corridor connecting an annex to a pond-side building (in traditional palatial-style architecture) | inspector | A passageway used to check for damage inside the dam embankment. Normally, it is off-limits to all but authorized personnel. However, if the dam is designated as a "dam open to the community," it may be used as a tour course. |
Foundation Ground | bulletin board system | Indicates the ground that is used to support the weight of the dam. Depending on the dam, the foundation ground may be quite deep. Incidentally, the embankment height, which indicates the height of the dam, is the height measured from the foundation to the top of the embankment. |

flood | flood | A flood occurs when the flow from upstream to the dam lake is higher than usual, even if the dam is not overflowing. |

Flood control capacity | high capacity (e.g. nuclear reactor) | The flood control capacity is the surcharge water level minus the flood stage limit water level. Flood control is carried out within this capacity. |
