Izikhukhula zase-Valencia 2024: Iqhaza Lokuguquguquka Kwesimo Sezulu kanye Nokuphambukiswa Komfula iTuria ka-1957

“Ukubona amanzi ekhuphukela kusofa wami bese efika endaweni engisebenzela kuyo ekhishini kwangethusa kakhulu. Ngihlala ngedwa efulethini eliphansi. Ngaphandle uma nginomshini wami wokuwasha egcekeni lami elingemuva, angiqiniseki ukuthi omakhelwane bami esitezi sokuqala bebengangisiza kanjani ngiphunyuke kukhukhula. Ngandlela-thile, ngosizo lwabo nobumbano, mina nenja yami, uChiwi, sagibela endaweni ephephile. Ngihlale ngibonga.” UPatricia Sousa Sardinha

Izikhukhula ezakhukhula eValencia ngasekupheleni kuka-Okthoba 2024 zaziphakathi kwezicekeleke phansi kakhulu emlandweni, zadalula izindawo ezihlukahlukene zokucekelwa phansi okungakaze kubonwe. I-“gota fría” engapheli ilethe izimvula ezinkulu, zehla imvula ecishe ibe unyaka wonke phakathi namahora angu-24. Igama elithi gota fría elihunyushwa ngokwezwi nezwi libe iconsi elibandayo, libizwa ngokusemthethweni ISIKHWAMA.

Imigwaqo yashintshwa yaba imifula edla izindwani, ikhukhula izimoto futhi yashiya yonke indawo icwile. Amakhaya ezazimelele izizukulwane ngezizukulwane zaba amagobolondo agcwele amanzi, imikhaya inyakaza ukuze isindise noma yini eyayingase ithwale njengoba amanzi ezikhukhula ayekhuphuka ngokushesha.

“Ngingomunye wezinkulungwane ezilahlekelwe yikho konke. Kodwa okungenani siyaphila. Siyazi ukuthi yithina esinenhlanhla futhi sithumela uzwelo nozwela emindenini nasezihlotsheni zalabo abangazange babe nenhlanhla njengathi.

Now, along with many others, I am volunteering to help others and to clear up.” Patricia Sousa Sardinha

UPatricia, owasinda futhi manje osevolontiya, wathatha ama-video nezithombe ezikulesi sihloko. Ulahlekelwe yikho konke. Nali ikhasi lakhe le-GoFundMe. Noma yimuphi umnikelo omncane wamukelekile, njengoba kunjalo namasheya ezinkundleni zokuxhumana.

Izimpendulo Zeziphathimandla Kuzikhukhula Zase-Valencia 2024 Zabangela Ukugxekwa Okubanzi

Impendulo evela kuziphathimandla ezikhukhuleni zango-2024 eValencia yathola ukugxekwa okukhulu, njengoba izakhamuzi eziningi zazizwa zilahliwe ngehora lesidingo. Ukubambezeleka kokuthunyelwa kwezimo eziphuthumayo kushiye imiphakathi esengozini izinakekele, njengoba imisebenzi yokuhlenga isilele ngokudabukisayo kulokho obekudingeka. Izindawo ezikhungethwe yizikhukhula zathola ukwesekwa okuncane kukahulumeni ngezikhathi zasekuseni ezibucayi, okubhebhethekisa ukuhlupheka kwalabo abavaleleke emanzini akhuphukayo. Intukuthelo nokukhungatheka kwaqubuka lapho iNkosi uFelipe VI ivakashela lesi sifunda esicekeleke phansi.

His presence, intended to offer solace, instead sparked outrage among locals who demanded accountability for the state’s perceived failure. Crowds jeered and shouted at the monarch, expressing their fury over inadequate flood defences and years of neglected infrastructure in the suburbs. The King, usually a unifying figure, found himself confronted by a population disillusioned and desperate for action, highlighting the growing rift between the people and their leaders in the face of repeated climate disasters.

Njengoba zingenazo izivikelo eziqinile ezivikela indawo emaphakathi ne-Valencia, lezi zindawo zaba isisekelo sokucekelwa phansi. Izakhamuzi zichaze amanzi ashayeka emigwaqweni yawo ngesivinini esesabekayo, okushiye sincane isikhathi sokubaleka. Abezimo eziphuthumayo bathwale kanzima ukuhambisana nenani lezingcingo ezikhungethwe yizinhlekelele njengoba izinkulungwane zabantu bezivaleleke ezindlini zazo. Izikole, amabhizinisi kanye nengqalasizinda yomphakathi kwasala kuyincithakalo, okwadala umonakalo omkhulu kwezomnotho emiphakathini esuvele ibhekene nezinselelo zokwanda kwamadolobha.

Amidst the chaos, stories of bravery and loss emerged. First responders worked tirelessly, navigating dangerous currents to rescue stranded residents, while neighbours formed human chains to help each other reach higher ground. Tragically, the floods claimed several lives, a grim reminder of the sheer force of nature. For many survivors, the psychological toll of watching their homes and livelihoods swept away was as overwhelming as the physical destruction. The aftermath of the floods left behind a landscape of debris and heartbreak, with the road to recovery expected to take years.

The devastation will hopefully serve as a wake-up call for local and national governments. The Turia River diversion, while successful in shielding the city centre, underscored its limitations as areas outside the protection zone bore the brunt of the disaster. As experts and officials assessed the damage, calls for more comprehensive flood management strategies grew louder, emphasising the urgent need to adapt to a world where extreme weather events are becoming more frequent and more severe.

Isayensi Engemuva Kwe-1957 Turia River Diversion kanye Nefa Layo

In 1957, the city of Valencia faced one of its most devastating natural disasters when the Turia River burst its banks, inundating large parts of the city and claiming at least 81 lives. The floodwater levels reached up to five metres in some areas, causing widespread devastation. The catastrophe prompted swift action from authorities, who implemented the “Plan Sur,” a massive civil Ubunjiniyela iphrojekthi yokuchezukisa umfula iTuria kude nenkaba yedolobha.

The diversion, completed in the late 1960s, rerouted the Turia River southward and created a dry riverbed in the heart of Valencia. This empty channel was later transformed into the Turia Gardens, a 9-kilometer-long urban park that has become one of the city’s most iconic green spaces. However, while the project was hailed as a triumph of flood prevention, the science behind flood dynamics and climate change suggests a more nuanced view of its impact.

I-Hydrological Insights: Indlela I-River Diversion Esebenze ngayo

The “Plan Sur” fundamentally changed the hydrology of the Turia River basin. By diverting the river, engineers effectively reduced the flood risk to central Valencia, protecting key infrastructure and densely populated areas from future inundations. The diversion involved creating a new artificial channel designed to handle the river’s maximum estimated discharge rate. This decision was based on extensive hydrological studies at the time, which analysed historical flood patterns and peak flow rates.

However, the calculations made in the 1950s and 1960s did not account for the accelerating impact of climate change, which has significantly altered precipitation patterns and increased the intensity of extreme weather events. Recent studies published in hydrology and climate science journals have shown that atmospheric warming is causing more frequent and intense rainfall, leading to flash floods that are more difficult to predict and manage.

Ukuguquguquka Kwesimo Sezulu: Isayensi Engemuva Kwezikhukhula Eziqinisiwe

Izikhukhula zango-2024 e-Valencia zaziqhutshwa yisimo sezulu esaziwa ngokuthi yi-“gota fría” noma iconsi elibandayo. Lokhu kwenzeka lapho inqwaba yomoya obandayo ishayisana nomoya ofudumele, onomswakama phezu koLwandle iMedithera, okuholela emvuleni enamandla futhi ethatha isikhathi eside. Njengoba amazinga okushisa embulunga yonke ekhuphuka, iMedithera isiphenduke isizinda sezinkinga zesimo sezulu esibangelwa yisimo sezulu. Amazinga okushisa olwandle afudumele andisa ukuhwamuka, okubuye kulayishe umkhathi ngomswakama owengeziwe. Lapho lo mswakamo ukhishwa, imvula ewumphumela iba nzima kakhulu kunesilinganiso esingokomlando.

A recent study by the European Centre for Medium-Range Weather Forecasts highlights how the Mediterranean’s warming waters are intensifying these events. The 2024 floods brought nearly a year’s worth of rain in a single day, overwhelming both natural and engineered drainage systems. While the Turia River diversion protected central Valencia from a worse fate, the areas surrounding the city, which lack similar flood defences, suffered catastrophic damage.

Imikhawulo ye-Geospatial kanye ne-Urban Planning

The flood dynamics of the 2024 disaster also shed light on the geospatial limitations of the 1957 diversion project. While the artificial river channel managed to keep floodwaters away from the heart of Valencia, it did little to address the risk to nearby towns and newly developed urban areas that have expanded over the past few decades. As cities grow and urban sprawl spreads into flood-prone areas, impermeable surfaces like roads and buildings reduce the land’s natural ability to absorb rainwater, exacerbating runoff and flood risk.

UDkt. Carmen Sánchez, isazi sokusebenza kwamanzi e-Polytechnic University of Valencia, uchaza isayensi ebangela lobu buthakathaka: “Ukwanda kwamadolobha kuye kwadlula ingqalasizinda yokulawulwa kwezikhukhula. Sakhe ezindaweni ezigcwele izikhukhula ngaphandle kwezixazululo ezanele zokudonsa amanzi, futhi izinhlobo zethu, ezake zabonakala ziqinile, manje azisafaneleki ukubhekana nezimo ezimbi kakhulu zamanzi ezibangelwa ukushintsha kwesimo sezulu.”

Ukuphathwa Kwezikhukhula Kokuqinisekisa Ikusasa

To adapt to this new climate reality, scientists and urban planners are calling for a holistic approach to flood resilience. This includes using advanced hydrological modelling to predict future flood scenarios under various climate conditions. Engineers are also exploring the use of permeable pavement, urban wetlands, and green roofs to increase water absorption in urban areas. Additionally, experts advocate for the creation of secondary flood channels and water retention basins to manage excess runoff.

The case of the Turia River diversion demonstrates both the successes and limitations of mid-20th-century engineering. While it has undoubtedly saved countless lives and protected Valencia from significant floods, it is now clear that more comprehensive, scientifically informed measures are needed. Addressing flood risk in a warming world requires a multidisciplinary approach, integrating meteorology, hydrology, climate science, and ukuhlela amadolobha okusimeme.

Izikhukhula zango-2024 kufanele zisebenze njengesixwayiso: ngisho nemisebenzi yobunjiniyela eyingqopha-mlando njengokuphambukisa komfula i-Turia ayisanele ngokuhlukaniswa. Abaphathi bezikhukhula besikhathi esizayo baseValencia kumele bahlanganise izifundo zomlando nocwaningo lwesayensi olusezingeni eliphezulu ukuze kuqinisekiswe ukuthi idolobha lizilungele izinselele zesimo sezulu esishintshayo.
