The structural failure of a dam can have catastrophic consequences, depending on the potential risk involved. Thus, in the case of dams which, following the relevant safety review, are found to lack the capacity to withstand the freshets they are designed to handle, measures must be taken to mitigate the associated risk. One means of doing so is to increase the discharge capacity of their spillways.<\/p>\n<\/li>\n<\/ul>\n<div style='text-align: justify'>\n<p>\n                    <strong>Energy<\/strong>\n                <\/p>\n<\/p><\/div>\n<ul>\n<li style='text-align: justify'>\n<p style='text-align: justify'>Changes in the streamflow regimes of rivers as a result of climate change, as well as the rise in energy needs, require an increase in the regulation capacities of reservoirs associated with hydroelectric power stations. Maintaining the freeboard implies the need to increase the discharge capacity per linear metre of the spillway, so that an increase in the normal operating level can be accommodated without compromising safety. To that end, one option is to modify the discharge profile, expanding it with the use of labyrinths or piano keys.<\/p>\n<\/li>\n<li style='text-align: justify'>\n<p style='text-align: justify'>This would also be applicable to an increase in irrigation and water supply requirements.<\/p>\n<\/li>\n<\/ul>\n<p style='text-align: center'>\n                <em>&#8216;The discharge capacity of some spillways is insufficient to handle river level regimes altered by climate change, with safety requirements higher than those used in their design&#8217;<\/em>\n            <\/p>\n<p style='text-align: center' \/>\n<h4 style='text-align: left'>\n                <strong>Competitive advantages<\/strong><br \/>\n            <\/h4>\n<p style='text-align: justify'>The advantages offered by POLILAB compared to its direct competition, namely existing commercial solutions involving labyrinth-type fuse gates, are as follows:<\/p>\n<ul>\n<li style='text-align: justify'>\n<p style='text-align: justify'>As it is recoverable, no significant expenditure needs to be incurred to replace it following its use in extreme freshet conditions.<\/p>\n<\/li>\n<li style='text-align: justify'>\n<p>Its retraction speed is expected to be adjustable, such that sudden and severe increases in flow volume downstream can be avoided.<\/p>\n<\/li>\n<li style='text-align: justify'>\n<p style='text-align: justify'>As it does not become detached from the main structure, it does not involve any risk as a result of impacts downstream.<\/p>\n<\/li>\n<\/ul>\n<h4 style='text-align: left'>\n                <strong>References<\/strong><br \/>\n            <\/h4>\n<p style='text-align: justify'>The team involved in the development of the POLILAB solution is made up of a multidisciplinary group of individuals with extensive experience and wide recognition in their respective fields: Technological knowledge (SERPA UPM), knowledge of the dam planning and construction sector (JGICSA), knowledge of and skill in complex numerical calculations (CIMNE), experience and resources in small-scale testing (CEDEX) and experience in the metals industry (VEMSA).<\/p>\n<h4 style='text-align: left'>\n                <strong>Stage of development<\/strong><br \/>\n            <\/h4>\n<ul>\n<li>\n<p>Concept<\/p>\n<\/li>\n<li>\n<p>Research<\/p>\n<\/li>\n<li>\n<p>\n                        <span style='text-decoration: underline'><br \/>\n                            <strong>Lab prototype<\/strong><br \/>\n                        <\/span>\n                    <\/p>\n<\/li>\n<li>\n<p>Industrial prototype<\/p>\n<\/li>\n<li>\n<p>Production<\/p>\n<\/li>\n<\/ul>\n<h4>\n                <strong>Contact<\/strong><br \/>\n            <\/h4>\n<p>\n                <strong>POLILAB contact<\/strong>\n            <\/p>\n<p>Miguel \u00c1ngel Toledo Municio, Francisco Javier Caballero Jim\u00e9nez, Miguel \u00c1ngel Fern\u00e1ndez Centeno<\/p>\n<p>ETSI Caminos, Canales y Puertos &#8211; UPM<\/p>\n<p>e: <span rel=\"86311b30a1312531b1311731b3312431b5312d3178310931a1311c31b7313a31af3134317a311b31bb3121316d311531b931\" class=\"cryptex \" style=\"\"><span class=\"CryptexImg ctxNu3EAcANmT8UtjBjautAVgJag34vnQ1O5cMmiRTVMdQ\"><\/span><\/span><\/p>\n<p>e: <span rel=\"86311b309e3127319e310a31a8312b31bd312331aa31153180311231af313931a9312f31bb31193179312931af311d3174311531aa31\" class=\"cryptex \" style=\"\"><span class=\"CryptexImg ctxo_LrJXIz_Lf-z1NFXkLi5E6osyWUg056jzqFaqjn8v8\"><\/span><\/span><\/p>\n<p>e: <span rel=\"86311b30a1312d31a4311d31ac312b31b2312c319f310b31ac312330b4313131b2312f31ad311431af311931b9311030bb312031a4310330b0313631\" class=\"cryptex \" style=\"\"><span class=\"CryptexImg ctxZ6ScEnHYGjxQ9d0Ttjab4SDCpvROLX12K2l0Xrh1RJA\"><\/span><\/span><\/p>\n<p>\n                <strong>UPM contact<\/strong>\n            <\/p>\n<p>Innovation and Entrepreneurship Programmes<\/p>\n<p>Technological Innovation Support Centre (CAIT) &#8211; UPM<\/p>\n<p>e: <span rel=\"86311b309d313231ab311731bd312031b4312731a73114316e312331b3312f31ae313031b8311531b2311d31a231113186312531a7313c3179312831ab31\" class=\"cryptex \" style=\"\"><span class=\"CryptexImg ctxR7neImVV1tJoTSyttUGBAuiESKXKLLyzTwJSN1lk9Z0\"><\/span><\/span><\/p>\n<div class=\"pdfprnt-buttons pdfprnt-buttons-product pdfprnt-bottom-left\"><a href=\"https:\/\/www.upm.es\/recursosidi\/wp-json\/wp\/v2\/product\/10972?print=pdf\" class=\"pdfprnt-button pdfprnt-button-pdf\" target=\"_blank\"><span class=\"pdfprnt-button-title pdfprnt-button-pdf-title\">Descargar ficha<\/span><\/a><\/div>","protected":false},"excerpt":{"rendered":"<p>Improve dam safety.
