  FIG. 1 is a diagram for explaining an operation mode of a dam according to an embodiment of the present invention. In addition, in the example shown in FIG. 1, there are a plurality of purposes that have both functions of flood control for flood control and water use reserved for a predetermined use (for example, power generation, irrigation, water supply, industrial water). (Hereinafter also referred to as a multi-purpose dam), and this embodiment is premised on water transactions by this multi-purpose dam.

  As shown in FIG. 1, the dam 100 according to the present embodiment is divided into a flood control capacity and a water use capacity, and the stored water in the dam 100 is divided into a flood control capacity and a water use capacity, respectively. ing. Furthermore, the flood control side is configured to allow elastic operation, while the water use side is configured to allow prior discharge. For this reason, for example, while retaining the water during heavy rains, etc., the water stayed in order to prevent flooding will be adjusted and the water control capacity will be used for other purposes, so that the stored water will be handled flexibly. When the typhoon is likely to approach, it can be adjusted in advance to lower the water use capacity. Of course, you may make it handle the water which stored the flowing water of the river at normal time elastically.

  Examples of water-controlling officers here include administrative organizations such as the Ministry of Land, Infrastructure, Transport and Tourism. Examples of water users include local governments, electric power companies, and industrial waters that use water discharged from water-controlling waters downstream. Companies that use the.

  With such a dam configuration, for example, a water dam and water users can efficiently and flexibly trade water resources according to environmental changes that can be assumed to some extent, such as floods, typhoons, and sunshine. 100 operation modes can be realized.

  Here, when dealing with the stored water in the dam 100 mentioned above, it demonstrates using FIG. FIG. 2 is a diagram showing an outline of a dam storage water trading system according to an embodiment of the present invention.

  As shown in FIG. 2, the dam storage water trading system 1 according to the present embodiment includes a water control person who manages water control for adjusting floods and a water use person who uses water used for a predetermined purpose. Management server 2 that manages information for trading the stored water stored in the dam 100 as flood control or water use for the purpose or request, settlement according to water transactions occurring between the water control person and the water use person or water users The transaction terminal 4 held by the financial institution 3 and the water control person and the water use person who exchange the information on the transaction amount in the water control or water use in the dam 100 is connected via the network 10 respectively. It is configured. Among these, the transaction terminal 4 is divided and comprised by what a flood control person and a water-use person hold and operate, respectively.

  The transaction here means a transaction related to the stored water stored in the dam 100, for example, a water transaction in which water stored in the dam 100 is traded, and an empty capacity in the dam 100. As a premise, there is an empty capacity transaction for trading. That is, the water transaction is used, for example, when exchanging the water stored in the dam 100 in the event of drought, and the air capacity transaction is, for example, exchanging the capacity for water utilization originally as an empty capacity for flood control when approaching a typhoon. This means a transaction used when

  Here, the management server 2 will be specifically described. FIG. 3 is a diagram showing a system configuration of a management server of the dam storage water transaction system according to an embodiment of the present invention.

  As shown in FIG. 3, the management server 2 includes a water volume management unit 21, a water volume displacement prediction unit 22, a transaction water volume calculation unit 23, a transaction management unit 24, and a database (illustrated as “DB”) 25. Yes.

  The water volume management means 21 acquires the measurement result of the water capacity in the dam 100 as the water volume data 50 and notifies the transaction terminal 4 of the flood control data or the water volume data 50 owned by the water control person and the water user. . The water amount data 50 here includes, for example, the water level of the dam 100, the amount of water discharged from the dam 100, the amount of water used downstream, and the like. As a method for obtaining the water amount data 50, for example, the water level of the dam 100 is changed in the numerical value of the water level meter installed in the dam 100, and the amount of water discharged from the dam 100 is opened by a valve installed in the flow path. It is conceivable to obtain numerical values measured from a flow rate sensor, a water level meter (for example, an electromagnetic water level meter), etc., for the amount of water used at the time, the operation record accompanying it, and downstream.

  The water displacement prediction means 22 predicts future water displacement of the dam 100 that is predicted based on the water volume data 50 acquired by the water volume management means 21 and the environmental change. That is, future water volume displacement of flood control or water use is predicted based on the water volume data 50 and environmental changes. With regard to the environmental change here, for example, various data related to the weather may be taken in as the weather information 60 in cooperation with the network 10 or other systems. Specifically, the water amount displacement predicting means 22 performs prediction based on future weather information 60 in consideration of water amount data that should be secured to a minimum within a predetermined period. Further, the water amount displacement predicting means 22 assumes a risk that occurs in each of the water control person or water user when predicting the future water amount displacement of the dam 100. Here, as an assumption method of the risk, for example, the risk evaluation for the assumed risk may be performed by weighting information on the displacement of water predicted by various environmental changes such as typhoon and heavy rain. That is, since the risk rank caused by the transaction can be recognized by multiplying the assumed risk by the weighting coefficient, the water control person and the water user himself / herself perform the transaction while judging the magnitude of the risk. Thereby, for example, it is possible to make a transaction taking into account the risk that the water level of the dam will not recover when the typhoon goes out of the expected course or becomes light rain.

  The transaction water volume calculation means 23 calculates the water volume data 50 that the water control person or water user related to the transaction releases or collects from others from the prediction result. That is, the water volume data 50 discharged to the other corresponds to the transaction volume used as the above-mentioned pre-discharge transaction, and the water volume data 50 collected from the other corresponds to the transaction volume used as the above-described elastic operation transaction. . At this time, specifically, the transaction water volume calculation means 23 calculates the water volume data 50 to be traded in monthly units or half-day units, for example. That is, the monthly transaction is, for example, a forward transaction in which transactions are performed in units of one month, and the half-day transaction is, for example, a spot transaction in which transactions are performed in units of day or night for half a day. Thereby, for example, even when the transaction unit price changes by month or day, it is possible to trade flexibly with the month or day as one unit.

  The transaction management unit 24 receives a request from the water control person or the water user from the transaction terminal 4, and the transaction water amount calculation unit 23 calculates the transaction amount actually traded by the water control person or the water user according to the demand or supply included in the request. Is managed based on the water amount data 50 calculated by the above, and the transaction amount is converted into a monetary amount and settlement management is performed with the financial institution 3. That is, the increase / decrease in the amount of water held by each water control person and water user who changes due to the transaction is managed, and processing related to the exchange of money generated by the transaction is executed.

  The database 25 stores at least the prediction result of the water amount displacement, the calculation result of the water amount data 50 relating to the transaction, and the actual transaction amount. That is, each data predicted by the water amount displacement prediction unit 22, each data calculated by the transaction water amount calculation unit 23, each data managed by the transaction management unit 24, and the like are stored. Furthermore, past performance data considering the topographic data may be stored. Thereby, for example, with respect to a certain area, the storage amount of the dam 100 corresponding to the precipitation amount of rain can be utilized in consideration of past empirical rules.

  Here, the processing procedure of the dam reservoir water transaction system 1 will be described. FIG. 4 is a diagram showing a communication sequence of the dam storage water trading system according to one embodiment of the present invention.

  As shown in FIG. 4, first, the management server 2 acquires the water amount data 50 by the water amount management means 21 (S1). That is, the water volume data 50 about a plurality of flood control persons and water users is acquired. And the management server 2 notifies the water volume data 50 which was acquired to the transaction terminal 4 of each water control person and water user (S2).

  Then, the water amount displacement prediction means 22 of the management server 2 predicts a future water amount displacement of the dam 100 based on the water amount data 50 and the environment data (S3). Examples of the data relating to the environment here include weather information 60 that can be acquired from the network 10 or the like.

  Further, the management server 2 calculates water volume data 50 relating to the trade between the water control person and the water user from the result predicted by the water volume displacement prediction means 22 (S4). And the water volume data 50 calculated based on prediction is notified to each transaction terminal 4 of a flood control person and a water user (S5). The data notified here should just be used as reference data regarding a flood control person and a water user's own transaction.

And if a transaction request | requirement is transmitted from each transaction terminal 4 of a flood control person and a water user based on the various water amount data 50 notified as mentioned above (S6), a transaction will be performed (S7). Specifically, for example, when the discharge capacity requested by the water user matches the collection capacity requested by the water control person, or when the capacity for passing water between the water users matches, the transaction is performed. . At this time, if the desired unit price is included in the transaction request, the transaction is performed in consideration of the case where the requested collection capacity or the interchangeable capacity is matched and the desired unit price is matched. May be. In this case, for example, it is conceivable to conduct a transaction using a unit price (for example, a unit price per 1 m ³ ) for a predetermined unit handled in the water transaction as a transaction unit price.

  Thereafter, the transaction management means 24 of the management server 2 manages the transaction volume generated for each transaction based on the water volume data 50 (S8). Specifically, for example, the transaction amount may be stored in the database 25 every time a transaction occurs.

  Then, the transaction management unit 24 converts the managed transaction amount into an amount (S9). Specifically, for example, a managed transaction volume may be extracted from the database 25 and a value converted into an amount may be stored in the database 25 in association with the transaction volume.

  When the transaction amount is converted into an amount of money by the management server 2, settlement information for performing settlement processing relating to water transaction is notified to the financial institution 3 (S10). At this time, for example, if the amount based on the transaction amount can be offset within the management server 2, payment does not occur, and thus the financial institution 3 need not be notified of settlement information.

  And in the financial institution 3, based on payment information, the settlement process of a flood control person and a water user is implemented (S11, S12).

  Through the above-described processing, in this embodiment, the use of the dam reservoir water is not limited to the original purpose of constructing the dam. By treating the general operation and pre-release as transactions involving monetary exchanges, it is possible for flood control and water users to use water efficiently and flexibly according to their own purposes and requests.

(Other embodiments)
In embodiment mentioned above, although the management server 2 has notified the water volume data 50 estimated with respect to the transaction terminal 4 in step S2 and step S5, it is not limited to this, For example, the flood control which operates the transaction terminal 4 It is good also as a structure which a person and a water user can access the management server 2 as needed, and can browse the change of the future water quantity data 50 estimated by the hour, day, and month unit.

  Moreover, in embodiment mentioned above, in the management server 2 which manages the information which trades the stored water currently stored in the dam 100 as flood control or water use, especially the profit according to water transaction is not generated, but this For example, the management server 2 may be configured to generate a margin for operation in water transactions. In this case, for example, the organization operating the management server 2 that controls the function as an exchange can receive cash back generated according to water transactions based on a predetermined standard.
