A Restoriver egy nemzetk\u00f6zi Interreg-program, amelyben kilenc orsz\u00e1g 28 szervezete m\u0171k\u00f6dik egy\u00fctt. A projekt c\u00e9lja term\u00e9szetalap\u00fa v\u00edzmegtart\u00f3 megold\u00e1sok kidolgoz\u00e1sa, vagyis olyan beavatkoz\u00e1sok tervez\u00e9se, amelyek a term\u00e9szet saj\u00e1t folyamataira \u00e9p\u00edtve seg\u00edtenek kezelni a kl\u00edmav\u00e1ltoz\u00e1s hat\u00e1sait. Magyarorsz\u00e1gon a WWF mellett \u00c9rd V\u00e1ros \u00d6nkorm\u00e1nyzata \u00e9s az Orsz\u00e1gos V\u00edz\u00fcgyi F\u0151igazgat\u00f3s\u00e1g vesz r\u00e9szt a munk\u00e1ban.<\/p>\n

\u00c1d\u00e1m Szilvia eml\u00e9keztetett arra, hogy az elm\u00falt \u00e9vekben a sz\u00e9ls\u0151s\u00e9ges id\u0151j\u00e1r\u00e1si jelens\u00e9gek egyre gyakoribb\u00e1 v\u00e1ltak. A 2024-es Boris ciklon idej\u00e9n egy h\u00e9t alatt t\u00f6bb mint 400 millim\u00e9ter csapad\u00e9k hullott, ami szeptemberi dunai \u00e1rhull\u00e1mot okozott. A Beliczay-szigetet akkor teljes eg\u00e9sz\u00e9ben el\u00f6nt\u00f6tte a v\u00edz. Ugyanakkor az idei tavasz \u00e9ppen az ellenkez\u0151 v\u00e9gletet mutatta: 2026 \u00e1prilisa az egyik legsz\u00e1razabb volt a m\u00e9r\u00e9sek kezdete \u00f3ta.<\/p>\n

A szakemberek szerint a probl\u00e9ma m\u00e1r nem puszt\u00e1n az, hogy a csapad\u00e9k egyenetlenebb\u00fcl \u00e9rkezik, hanem az is, hogy \u00f6sszess\u00e9g\u00e9ben egyre kevesebb v\u00edz \u00e1ll rendelkez\u00e9sre. Ez\u00e9rt k\u00fcl\u00f6n\u00f6sen fontos minden olyan megold\u00e1s, amely seg\u00edt helyben tartani a lehull\u00f3 vagy az \u00e1rvizekkel \u00e9rkez\u0151 vizet.<\/p>\n

A Beliczay-sziget a Duna \u00e9s az \u00e1rv\u00edzv\u00e9delmi t\u00f6lt\u00e9s k\u00f6z\u00f6tti ter\u00fcleten fekszik. B\u00e1r \u00e1rv\u00edz idej\u00e9n id\u0151nk\u00e9nt teljesen v\u00edz al\u00e1 ker\u00fcl, a szak\u00e9rt\u0151k szerint ma m\u00e1r sokkal nagyobb gondot jelent a tart\u00f3s v\u00edzhi\u00e1ny.<\/p>\n

A Duna medre az elm\u00falt \u00e9vtizedekben jelent\u0151sen m\u00e9ly\u00fclt, \u00edgy az alacsony v\u00edz\u00e1ll\u00e1sok egyre gyakoribbak. Emiatt a foly\u00f3 nemcsak t\u00e1pl\u00e1lja, hanem asz\u00e1lyos id\u0151szakokban gyakorlatilag le is csapolja a k\u00f6rnyez\u0151 ter\u00fcleteket. Ennek k\u00f6vetkezm\u00e9nye, hogy a term\u00e9szetes \u00e9l\u0151helyek \u00e1llapota romlik, az erd\u0151kben pedig egyre gyakrabban jelentkeznek asz\u00e1lyk\u00e1rok \u00e9s betegs\u00e9gek.<\/p>\n

A projekt egyik \u00e9rdekess\u00e9ge, hogy a szakemberek nemcsak m\u0171szaki vizsg\u00e1latokat v\u00e9geztek, hanem a helyiek v\u00e9lem\u00e9ny\u00e9t is kik\u00e9rt\u00e9k. A F\u00f6ldrajzi M\u00fazeumban tartott lakoss\u00e1gi f\u00f3rumon t\u00f6bb tucat \u00e9rdi osztotta meg tapasztalatait \u00e9s javaslatait.<\/p>\n

\"\"<\/p>\n

Az egyik legizgalmasabb \u00f6tlet \u00e9ppen a helyiekt\u0151l \u00e9rkezett: t\u00f6bben felid\u00e9zt\u00e9k a Beliczay-sziget \u00e9szaki r\u00e9sz\u00e9n egykor m\u0171k\u00f6d\u0151 strandot, \u00e9s felvetett\u00e9k, hogy \u00e9rdemes lenne megvizsg\u00e1lni, helyre\u00e1ll\u00edthat\u00f3-e a kavicsos partszakasz.<\/p>\n

A Budapesti M\u0171szaki Egyetem szakemberei hidrodinamikai modellez\u00e9ssel vizsg\u00e1lt\u00e1k a lehets\u00e9ges beavatkoz\u00e1sokat.<\/p>\n

A leg\u00edg\u00e9retesebbnek az bizonyult, hogy a sziget m\u00e9lyebben fekv\u0151 r\u00e9szein visszatartan\u00e1k az \u00e1rvizek sor\u00e1n \u00e9rkez\u0151 vizet. A tervek szerint k\u00e9t zsilip seg\u00edts\u00e9g\u00e9vel a magas v\u00edz\u00e1ll\u00e1sok idej\u00e9n felt\u00f6lt\u0151d\u0151 m\u00e9lyed\u00e9sekben hetekig megmaradhatna a v\u00edz, amely \u00edgy lassan besziv\u00e1rogna a talajba, jav\u00edtva a talajv\u00edz-ut\u00e1np\u00f3tl\u00e1st \u00e9s m\u00e9rs\u00e9kelve az erd\u0151k v\u00edzhi\u00e1ny\u00e1t.<\/p>\n

Vizsg\u00e1lt\u00e1k a Beliczay-mell\u00e9k\u00e1g \u00fajb\u00f3li megnyit\u00e1s\u00e1nak lehet\u0151s\u00e9g\u00e9t is, de a kutat\u00e1sok szerint ez rendk\u00edv\u00fcl nagy f\u00f6ldmunk\u00e1val j\u00e1rna, r\u00e1ad\u00e1sul t\u00f6bb k\u00e1rt okozna, mint hasznot, ez\u00e9rt ezt a v\u00e1ltozatot elvetett\u00e9k.<\/p>\n

Elemz\u00e9s k\u00e9sz\u00fclt a sziget \u00e9szaki cs\u00facs\u00e1n tal\u00e1lhat\u00f3 egykori mederszakasz r\u00e9szleges helyre\u00e1ll\u00edt\u00e1s\u00e1r\u00f3l is. Ez nemcsak a kavicsos part vissza\u00e1ll\u00edt\u00e1s\u00e1t seg\u00edthetn\u00e9, hanem kedvez\u0151bb \u00e9l\u0151helyet teremthetne a halak sz\u00e1m\u00e1ra is. A szakemberek szerint azonban ehhez tov\u00e1bbi felm\u00e9r\u00e9sek sz\u00fcks\u00e9gesek.<\/p>\n

A projekt nemcsak tervez\u00e9sr\u0151l sz\u00f3lt. A WWF \u00e9s partnerei t\u00f6bb szeml\u00e9letform\u00e1l\u00f3 programot is szerveztek.

Emellett egy 24 \u00f3r\u00e1s bioblitz sor\u00e1n t\u00f6bb mint harminc szak\u00e9rt\u0151 m\u00e9rte fel a Beliczay-sziget \u00e9l\u0151vil\u00e1g\u00e1t.

\u00c1d\u00e1m Szilvia el\u0151ad\u00e1s\u00e1nak v\u00e9g\u00e9n egy t\u00f6bb mint sz\u00e1z\u00e9ves t\u00e9rk\u00e9pet mutatott be.

A Restoriver projekt ugyan most lez\u00e1rul, de a kidolgozott tervek alapot adhatnak arra, hogy a j\u00f6v\u0151ben a Beliczay-szigeten val\u00f3di term\u00e9szetalap\u00fa v\u00edzmegtart\u00f3 beavatkoz\u00e1sok val\u00f3suljanak meg, amelyek egyszerre seg\u00edthetik a helyi \u00e9l\u0151vil\u00e1g meg\u0151rz\u00e9s\u00e9t \u00e9s a kl\u00edmav\u00e1ltoz\u00e1s hat\u00e1saihoz val\u00f3 alkalmazkod\u00e1st.<\/p>","protected":false},"excerpt":{"rendered":"
