3340-Kannawaki Dam

As the name suggests, the Hanna Waki Dam is located on the side of the Hanna Dam. I was actually aiming for the main body of the Hanna Dam, but when I noticed it, I saw the side dam.... I know that no one will be satisfied if I upload such a picture, but I wanted to upload it as a proof that I saw it.... / rockfill dam / 37m

Dam in Okinawa Prefecture

0000-Ishikawa Dam

This dam, like Yamashiro Dam (2893-Yamashiro Dam/Yamashiro Dam), was photographed from the Okinawa Expressway during a tour of Okinawa. I was able to photograph it! However, it seems that the height of the embankment is less than 15m, and it is treated as a weir. So, it was not listed in the dam handbook... / 13.2m

Dam in Okinawa Prefecture

2893-Yamashiro Dam

When I saw the characters for "Yamashiro Dam," I wondered if it was "Yamagusuku. I thought it might be "Yamagusuku," but it was a surprisingly common reading. Sometimes I get confused when I think that Okinawan kanji must be difficult to read, but it is not. I was surprised to learn that the dam was originally built by the U.S. Army. The history of the dam is typical of Okinawa. It was called Tengan Dam until March 1998. / Earth dam / 29.9m

fillet

A fillet is a reinforcing thickening section placed at the bottom of the upstream side of a dam embankment. They are installed when the strength of the concrete dam cannot be maintained or to ensure stability against overturning. They are installed in a triangular shape so that the upstream slope is slower.

dam tour

A dam tour is a visit to several dams. （It is (mainly) a term for dam enthusiasts. In most cases, you can reach several dams by going upstream on the main stream and tributaries of a river. The Oigawa and Tenryu Rivers in Shizuoka Prefecture have so many dams that they are called "dam heaven," and it may take a whole day to visit them, or even longer in some cases.

Surface water intake system

A surface intake facility is a facility that withdraws water from the surface where the water temperature is warmer than the lower levels. It has the advantage of not affecting crops and organisms. In addition, dams for power generation are sometimes installed to prevent turbid water. In some dams, aging surface intake facilities are replaced with selective intake facilities to improve reliability, operability, and maintenance management.

1332-Anno Dam

The first dam I picked up for my so-called first dam visit of 2010 was this Anno Dam, which I had been planning to visit since the end of the year. I had already researched that it is an irrigation dam for agriculture, so I thought it would not be flashy, but there is no denying that it is a magnificent dam. / Gravity concrete dam / 73m

emergency flood discharge

An emergency flood discharge is a gate that prevents overflow of a dam during a flood. It is used in the event of a flood that is too large to be discharged by the normal flood discharge. In most cases, the emergency flood discharge is located near the top of the embankment.

1465-Tachigahata Dam

After visiting Ishii Dam, we headed to Tachigahata Dam. However, I was very impressed that the interesting properties were scattered around before we reached the embankment, and the embankment was not the only thing to see. The stone-lined dam was clearly distinct from the concrete dams we had seen before. I am sure that the people of the Meiji period must have seen a landscape not much different from this picture. / Gravity concrete dam / 33.3m

non-flood season

The non-flood season refers mainly to the winter months, when precipitation is low. This means that the water level of the dam lake is higher. The period varies from dam to dam and is set in detail. ⇔Flood season

weir

A weir is a structure built across a river. Under the River Act, a dam is defined as a structure that is 15 meters or longer, while a weir is generally defined as a structure that is shorter than 15 meters. Sometimes it is simply called a weir. There are two types of weirs: fixed weirs, which have no moving parts, and movable weirs, which have moving parts to control the flow of water. In addition, there are wash weirs that allow water to overflow the top of the weir.

buttress dam

Buttress dams, also known as "support-wall dams," are dams that use concrete walls for support. There are only six such dams in Japan, and the Mitaki Dam (Tottori Prefecture), completed in 1937, was the last buttress dam in Japan. Because cement was an expensive material before World War II, buttress dams, which require less cement than gravity-type concrete dams, attracted attention and were constructed. However, as cement became less expensive, it was difficult to find engineers to work on the formwork, maintenance was not easy and costly, and there were durability problems.

1519-Ishii Dam

This is a Hyogo Prefecture-operated flood control dam that also serves the purpose of recreation and has a gallery inside the embankment. I had done a little preliminary study of the dam beforehand, and was very curious to see a dam with "recreation" as its purpose. However, it seemed to fulfill its purpose, and there were quite a few people walking around. / Gravity concrete dam / 66.2m

dam curry

Dam curry is a type of curry in which the roux is made to resemble a dam lake and the rice portion is made to resemble an embankment. Like real dams, there are gravity, arch, and fill types. Kurobe Dam Curry at the rest house of Kurobe Dam (0848-Kurobe Dam) has a long history, but it was Sanshuya in Honjo, Sumida-ku, Tokyo, that introduced it to the media and spread it in earnest. This has led to an increase in the number of restaurants selling dam curry in various areas of Japan, including as a way to revitalize their towns.

class 2 river

Second Class Rivers are rivers other than First Class Rivers as defined by the River Law, which are administered by the prefectural government (governor). The term "second class" does not indicate the size of the river, such as width, etc. Therefore, a river may be a first class river even if its size is small, or a second class river even if its size is large.

dam card

Dam cards are cards that the Ministry of Land, Infrastructure, Transport and Tourism and the Japan Water Agency began distributing in conjunction with the 2007 Forest and Lake Friendship Season event, mainly to raise awareness. Although they are the same size as so-called trading cards, they do not have a game element such as a match. Initially, dam cards were distributed only at dams managed by the Ministry of Land, Infrastructure, Transport and Tourism and the Japan Water Agency, but some prefectural dams have also begun to distribute the cards, and the number of dam cards is expanding.

conduit

A conduit is the channel from the overflow area downstream of the dam to the dam dam attenuator, and is used to ensure the proper flow of water from the flood discharge. There are several types of conduits, such as the levee downstream type often seen in gravity concrete dams, the chute type often seen in fill dams, and the tunnel type using tunnels.

Top (Crest)

The top end is the upper part of the dam embankment or levee. In many cases, dams dedicated to power generation are closed to the public, but in the case of multipurpose dams, the top of the dam may be open to visitors. Some multi-purpose dams open their topsides to visitors. In some cases, national highways are located above the topsides, and are referred to by enthusiasts as "national highways at the topsides. The width of the embankment is defined as 3 m or more based on the planned high water flow rate.

telemeter

A telemeter is [telemeter] a device that deciphers, indicates, or records measured quantities sent as electrical signals from a distant place (from Shinjirin Sanseido). Telemeters at dams mainly transmit measurement data from rain gauges and water level gauges to the management office. Based on the measured data, they are used for various gate operations and various warnings. Recently, there are also many cases where the measured data is distributed via the Internet.
