Abstract
'Sea hollow (UTSURO)' is part of a water area surrounded and enclosed by a bank structure in a tide-level-changing water area. By using a tide generator by a 'sea hollow (UTSURO)' which spreads a canal mouth that opens a 'sea hollow (UTSURO)' water area via a canal toward a river's upstream part to open it in a tide-level-changing river-upstream water area, the functional extension of a rive is shortened, a river bed gradient is steepened, the flow rate and the tractive force of a river are increased, a river bed is deepened, a river section area is enlarged, and a drainage of inner basin and a flood discharge capacity are increased. At a downstream part, the size of 'sea hollow (UTSURO)' A is increased, a tidal stream producing capacity is boosted, a tidal stream as large in quantity as a flood is produced, and a water stream section area is enlarged, thus contributing to a flood control effect and water way maintenance. In addition, in order to remove enormous amounts of sand and earth forced to flow to a river mouth and deposited on a river channel, another holes-rich 'sea hollow (UTSURO)' B is installed to capture slurry by the action of high tide for precipitating and cleaning to thereby develop tidal flats and reclaimed lands, and, at a low tide, clean supernatant is collected into a channel to thereby produce tide. Furthermore, the installing of an outer block-enclosing bank (8) can prevent the outflow of slurry into an outer water area and further enhance their effects to maintain a canal. Additionally, in order to maintain the functions of the 'sea hollow (UTSURO)' A, a canal length is increased to prevent a turbid water inflow.

The specific embodiment
For the present invention is further elaborated, describe with reference to the accompanying drawings below.
Shown in the vertical view of Fig. 1, have in the waters of variation at the trend water level, surround the waters that forms with dam configuration 1 and be called as " hollow marine site (UTSRO) ", the water route mouth in the waters of open " hollow marine site (UTSRO) " A in the water route is extended to upper river portion, utilize the trend generation device of open " hollow marine site (UTSRO) " A at place, upper river waters with trend SEA LEVEL VARIATION, make and become the river of morning and evening tides domination from opening port to dirty Lb interval, if it is Lo that the river in past prolongs, the prolongation of the function in river is (Lo-Lb) so, upper river portion is extended for La, and the function that can shorten the river prolongs.
In the forming process in river, form the alluvial plain by the sand mud that flows out, cause the scale in river to enlarge, in addition, except causing the river that slowly flows, the master stream of river mouth portion also can be divided into several tributaries and flow into the sea.
In the river mouth portion in such tributary 3, the waters that the non-permeability dyke (dam) 1 of formation " hollow marine site (UTSRO) " shown in Figure 1 by constituting A surrounds, by tributary 3, be released into main flow 4, if change thereby in off-lying sea 6, produce tidal level, by the downstream portion 4 in river, through tributary 3 (open water route), inflow and outflow is in " hollow marine site (UTSRO) " A repeatedly.
If claim that the original firm discharge in river is Qo and claim that the trend that flows out is Qc from " hollow marine site (UTSRO) " A, the water yield Qb of the lower reaches of river portion 4 when then forming ebb is (Qb=Qo+Qc).Though the original firm discharge Qo in river limits according to river itself, the trend Qc that flows out from " hollow marine site (UTSRO) " A can increase according to the scale of " hollow marine site (UTSRO) " A.
By enlarging the scale of " hollow marine site (UTSRO) " A, formation makes trend produce " hollow marine site (UTSRO) " A of the scale that flow Qc and the flood discharge in river be equal to mutually, makes in the river always to flow out the tide flow Qb that inflow can be equal to mutually with flood discharge in dirty 4 the waters repeatedly.
Like this, flowing to river mouth, river portion 4 even be equal in the huge trend Qb of flood, because it is the current that so-called morning and evening tides produces, is the current of below the seawater horizontal plane (THWL), can not overflow the dyke height of land area.
Therefore, as shown in Figure 1, by in the river mouth in tributary 3, constituting " hollow marine site (UTSRO) " A, though the prolongation Lb that seems lower reaches of river portion 4 has the character of straits or beach etc. at the downstream portion that constitutes the river in shape on the function.Therefore, if whole piece river in the past is Lo, (Lo-Lb) promptly is that the upstream portion river prolongs so, and the function that La then becomes new river prolongs.
The riverbed height of the upper river portion in past is Ho, and the channel gradient in past then is (Ho/Lo), and the channel gradient Ia in new river is (Ho/ (L-Lb)), and as shown in Figure 2, Io＜Ia is so channel gradient becomes greatly.
In case it is big that the channel gradient of upstream portion becomes, flow velocity also becomes greatly, and current scour power has improved, and the riverbed is rinsed the darker of excavation, and the flood mediation section in river becomes big.Thus, slowly offset a copious, rapid flow of words phenomenon, improved the ability of harnessing the river.
In addition, the downstream portion 4 in the river, the scale of aforesaid by enlarging " hollow marine site (UTSRO) " A produces the trend that is equal to mutually with the flood discharge in river, can deepen the riverbed, enlarges flood mediation section and improves the effect of harnessing the river of lower reaches of river portion 4.
And a large amount of sand mud of going out from upstream flow at river mouth portion place are deposited in the river course, make the river course shoal, and the mediation ability of flood and navigation of boats and ships or the like are produced obstacle.
Thus, in the waters of river mouth portion, select to pile in the future and bury and form the waters of doing ground, setting is by having lacunose dyke (dam) (seeing through the dyke (dam) of structure) 8 another " hollow marine site (UTSRO) " B (steady stability purification waters) that surround, utilize the rising tide effect of morning and evening tides, the huge river muddy water that flows out to the river mouth is incorporated in " hollow marine site (UTSRO) " B and the B ' waters 9, make its subsiding and purifying, produce dried ground or heap and bury ground or the like, in ebb tide, the water after the subsiding and purifying is accumulated in the river course, in the river course, produce trend, can further improve the current scour power in river course in the river mouth, the river course is maintained dark river course, all the time the current of guaranteeing the flood at river mouth portion place pass through section, thereby help the dredging of keeping in air route.
And, by non-permeability dyke (dam) or semipermeability dyke (dam) dyke (dam) 8 ' is set with the outline portion that surrounds " hollow marine site (UTSRO) " B, prevent that muddy water from flowing out to off-lying sea 6, the saline waters that keeps the river mouth, make the aquatic resources of river water area become abundant, increase the trend in river in the river mouth portion, improve the mediation ability of flood, improve the effect of keeping and harness the river in air route.
In addition, for the permanent function of keeping the trend generation device of utilization " hollow marine site (UTSRO) " A, stop the turbidity in river to flow in " hollow marine site (UTSRO) " A, the prolongation Lb in the open water route 3 of lengthening " hollow marine site (UTSRO) " A, must satisfy Lb＞Vb * t * α, Vb: the mean flow rate in open water route, t: duration of tide, α: the condition of the diffusion coefficient in water route.(therefore, opening the muddy water route that prevents that water route 3 is also referred to as " hollow marine site (UTSRO) " A)
Industrial utilizability
In the river mouth in river section because the silt particle that flows out from upstream portion, and modern age two sides heap bury Deng, so that slowly increase in the prolongation in river, the river mouth in river section place, and so that the river of river integral body The bed gradient slows down, and causes the flood dredging ability in river to reduce. In addition, cause the river at river mouth section place Bed rises, and causes shipping and dike internal water accumulation to get rid of difficulty.
Thus, utilize natural energy as a kind of, added the potential energy of river gravity in the past, Strengthen the energy of morning and evening tides at the downstream portion place, seek the dredging of keeping in river course, purify muddy water, concentrate mud Mud in the water, form wide dried ground or pile buried system, a kind of during it is implemented because Run into flood, the situations such as climax, and the system that short-term is implemented, be not in the past utilize oil and coal Keep the system of dredging Deng machinery, but can be melted into mutually the system of environment, industrial Has very big utilizability.
