Can the Technological Handicraft Center be flooded? (11/11/2020)

| Pedro José Sánchez, Town Planning Councilor, offers his arguments about the possible future location of the city museum | "It is no secret (because we have always defended it that way) that at Ganar Totana - IU we believe in valuing our heritage as soon as possible through a museum installed in the city.

Due to its location, its characteristics and its facilities, it must be the Technological Center for Crafts (CTA).A collation of the press conference offered by Mayor Juan José Cánovas and First Lieutenant Verónica Carricondo, in which they mentioned this same idea, a very interesting argument could be observed in comments to dismantle the CTA as a future museum: its condition in the area floodable.I am going to use a series of arguments in relation to this fact so that, who so wishes, can form an opinion with a more complete perspective on the subject, which broadens the views beyond the intentional suggestion that a possible flood could end museum and with the pieces.The ZI, flood zones, are determined through studies carried out by basin organizations (CHS in our case), using historical data on floods, flow measurement, geography studies, etc.

The cartography of flooded areas is the most approximate tool that administrations have to anticipate a possible flood and such data must be taken into account.

However, we must know how to interpret them, as recommended by the CHS itself on its official website:“It should be noted that the flooded areas obtained have important limitations in terms of their coincidence with the representation of the real flood that would occur in a specific event.Some of these LIMITATIONS stand out:In large and heavily anthropized floodplains, the difficulties to adequately represent in the model all the artificial elements that influence the flow characteristics, and the computational limitations of the hydraulic model given the enormous amount of data to be processed, can also make that the actual flood results differ from the model predictions.

"In other words, when the channels as they pass through urban areas are studied, the studies cannot accurately forecast the behavior of the waters, so more specific analyzes are needed to establish these forecasts.

An example of this is that for the units of action next to the channels of the General Plan, a specific study on their flooding is requested, a fact that, if the hydrographic studies were 100% reliable, would not be necessary.

But as we see, there are cases in which it is difficult to forecast accurately.If we take as a reference the cartography used to fence the flooding of the CTA, we see that the entire plain that remains from the urban area to the highway is not indicated, an area that we know from experience is the most sensitive to flooding, and these studies they don't even point out your risk.

Therefore, the calculation of the upstream flow behavior would vary enormously if this expansion plain of the waters were taken into account.

And it is that, for example, this cartography, being of constant review and study, to this day does NOT indicate the end of the riverbed of the Rambla de Lébor or the season as flooded areas, being everyone known what its real situation is in the event of rains copious.

The DANA pass can serve as an indication of the behavior of the water in a current situation.[Image 1: Areas of draft T = 500 years indicated in Totana, where we see that the area of ??the highway is not mapped, which has experienced various episodes of flooding]But let's not rule out the flooding of the CTA, because it is a realistic risk.

Now, does this rule out the building as a possible museum?If we ruled out the musealization of spaces found in flood-prone areas, what would happen to museums such as the Molinos del Río, immersed in the Segura riverbed? Or with the old military prison where the Naval Museum of Cartagena or the Peral Museum is located, immersed in a flood zone of the Rambla de La Algameca? Should these spaces be dismantled and discarded due to a cartographic imperative? Is design and planning not capable of solving a recurring problem in our cities?For this we also have answers.

The guide for the design and rehabilitation of buildings located in flood-prone areas, released by the Ministry of Ecological Transition in October 2019, specifies the special sensitivity that must be taken in the case of museums, libraries and archives.

For these cases, in addition to the relevant architectural solutions for waterproofing buildings, it is recommended:IV.

Move the most vulnerable uses to the upper floors or even raise the building.Not counting its basement, the CTA has a ground floor, two upper floors and a covered roof terrace.

Would it be impossible to dedicate the upper floors to the exhibition of the most valuable pieces, and to dedicate the ground floor to a more than pertinent audiovisual room and temporary exhibition space? What interests exist to discredit an option that, as we see when taking the floodplain arguments, would be more than justifiable?And most importantly: along with the discredit of the CTA, the use of the site's interpretation center as a museum is defended.

It should be remembered that we are talking about a ground floor building that also periodically suffers rainwater leaks inside, as it is designed in an area of ??depression in the land.

Where would the pieces have a better future?As a final note, if what is really intended is to protect the cultural heritage of Totana from a possible flood, it is striking that at no time is the Archaeological Museum of Lorca mentioned, where a large part of our heritage has been found for decades, which It has always been in a floodable area and on which you will not find news of the flooding of its parts or in the sad moment of the flood of 2012.

Of course, in Lorca, Juan José Cánovas does not rule.Pedro Jose Sanchez [Image 2: Areas of draft T = 500 years on Lorca, affecting the Archaeological Museum]
