Definitions

  • the invention relates to a device for flowing water with changing salinity or Suspended matter concentrations in tidal conditions Brackish water zones, with a side branch or Extension in the manner of a lock access or a harbor basin, to avoid silt / sand deposits, being in the area of the beginning of the Branch or extension related to a flood current over a distance from the bank boundary Deflection partition forms a channel, the Cross-sectional area a small part of the entrance cross-sectional area the junction or extension and its inlet opening in the river area in the area of the beginning and its outlet opening in the area of the branch or extension lie.
  • the density of a tidal river can both through changes in salinity as well vary due to changes in the suspended matter content.
  • this object is achieved by that the deflection partition covered in the upper area is arranged to the water depth and in the lower Area related to the water depth in the river area there is an additional baffle for distraction a dense stream close to the bottom towards the middle of the river starting from the bank boundary in the area of Deflection partition runs and into the river area protrudes.
  • the diverting partition at least in the area outside of the one filled with material Area is arranged on stands.
  • a favorable training is created in that each baffle for vortex-free deflection S-shaped is trained.
  • the river 1 has the tidal current 4 at high tide and additionally through the penetrating sea water Density flow 3 in the area near the bottom.
  • the arrows indicate the backward tide 19 and Density flow 18.
  • the arrows Density equalization flows at high tide according to arrows 17 and shown at low tide according to arrows 22, which then always act when the salinity or suspended matter in the Water in river 1 is larger than in port basin 2.
  • a Filling flow control system with a diverting partition 6 in upper area and a baffle 5 in the lower area shown.
  • a channel 24 in the upper region which forms water depth.
  • This amount of water is divided into the tidal volume 11 for the port basin 2 and a backflow portion 10 which flows back into the river area 1 and one Density compensation flow 17 back into the flowing water 1 pushed away.
  • baffle 5 arranged behind the up to the bank boundary 23 a space 13 up to an approximately vertical end wall 26 with material, such as. Sand with stone cover, is filled up.
  • material such as. Sand with stone cover
  • the density flow 12 thus rejected in connection with the partial outflow 10 cause a density compensation flow 17 at high tide as far from the port entrance 2 is pushed so that it remains in the river area 1.
  • the otherwise of the Density compensation flow in the area of the river bed carried entry of sand and silt and the resulting resulting high sedimentation in the harbor basin 2 prevented.
  • junction 2 At the end of junction 2 is beginning at the bank boundary 25 shows a baffle 14, which in arranged lower area of the water depth and in the curved Course led into the river area 1 is.
  • the area 15 between the baffle 14 and the bank boundary 25 is like the area 13 with material up to vertical termination 16 filled.
  • the baffle 14 should during the ebb phase with the Tide flow 19 and density flow 18 these Deflect density flow 18 according to arrows 27, that in combination with an outflow 28 from the port basin 2 penetration of a density compensation flow 22 is prevented and in this way also at Low tide otherwise entry of silt or sand in the harbor basin 2 is prevented.
  • the deflection systems are for example steel, reinforced concrete or wood.
  • the end wall 26 of the filling area 13 for the Deflection wall 5 is in an aerodynamically rounded shape 29 performed.
  • the deflection partition 6 is in the embodiment 5 outside the backfill 13 of the baffle 5 arranged on stilts as a stand 30.
