El presente artículo muestra el resultado de la investigación local, realizada en la sede Panorama de la institución educativa Caguancito, municipio de Garzón, departamento del Huila en Colombia. El objetivo de la investigación es analizar el impacto de la propuesta curricular del área de Ciencias Naturales frente al uso y cuidado de los recursos naturales en la institución y la región. La metodología es de carácter cualitativo con un enfoque descriptivo. Para la recolección de la información se empleó una matriz de revisión documental, encuestas y entrevistas, a 25 estudiantes de las sedes de la básica primaria, 22 padres de familia, pobladores y docentes de la institución. Los resultados obtenidos evidencian ausencia de contendidos y estrategias didácticas, que favorezcan el cuidado y protección de los recursos naturales en el plan curricular de Ciencias Naturales. El recurso natural más representativo en la región, son los nacederos de agua, estos suministran el líquido al 80 % de las familias para el sostenimiento de las activadas domésticas y la producción agrícola; estas fuentes están siendo afectadas por el consumo desmedido de la comunidad y la falta de protección. Se intervino el currículo diseñando una estrategia curricular didáctica transversal, que permite el cuidado y la preservación de los recursos naturales, especialmente los nacederos de agua, propuesta en la que docentes, estudiantes y padres de familia puedan participar en las actividades fortaleciendo la conciencia ambiental.

Department of hydraulic engineering and hydraulics FGBNU «VNIIGiM them. A.N. Kostyakova «has a long history. For many years, the department’s staff has been such scientists and water engineers with extensive experience as M.A. Volynov, V.S. Verbitsky, S.S. Medvedev, N.V. Lebedev, B.C. Panfilov, T.G. Voynich-Syanozhentsky, V.A. Golubkova, G.V. Lyapin and others. The department solved a wide range of tasks, the main areas of research were the following: – theoretical and applied hydrodynamics and hydraulics, with reference to the open channel flows that affect the state and level of safety of the hydraulic structures; – integrated use and protection of water bodies – water sources and water sources of water resources used in land reclamation; – development of measures and technical solutions for the protection of objects from the negative effects of water; – theoretical substantiation of works to improve the safety level of the GTS (declaration); – development and implementation of digitalization methods for solving design, construction, operation and control of landreclamation facilities. Currently, promising areas of research is the development of a decision-making algorithm in the designation of measures to rationalize the provision of resources to water amelioration. The algorithm is developed on the basis of a detailed study, systematization and processing of data both on safety and on the efficiency of systems and structures, ensuring the delivery of irrigation water of the required quality and in sufficient quantity from a water source to the field.

Monitoring water levels of lakes, streams, rivers and other water basins is of essential importance and is a popular measurement for a number of different industries and organisations. Remote water level monitoring helps to provide an early warning feature by sending advance alerts when the water level is increased (reaches a certain threshold). The purpose of this report is to present an affordable solution for measuring water levels in water sources using IoT and LPWAN. The assembled system enables recording of water level fluctuations in real time and storing the collected data on a remote database through LoRaWAN for further processing and analysis.

<p>Executive summary: Porous resorcinarene-containing polymers are used to remove halomethane disinfection byproducts and 1,4-dioxane from water.<br></p><p><br></p><p>Disinfection byproducts such as trihalomethanes are some of the most common micropollutants found in drinking water. Trihalomethanes are formed upon chlorination of natural organic matter (NOM) found in many drinking water sources. Municipalities that produce drinking water from surface water sources struggle to remain below regulatory limits for CHCl<sub>3</sub> and other trihalomethanes (80 mg L<sup>–1</sup> in the United States). Inspired by molecular CHCl<sub>3</sub>⊂cavitand host-guest complexes, we designed a porous polymer comprised of resorcinarene receptors. These materials show higher affinity for halomethanes than a specialty activated carbon used for trihalomethane removal. The cavitand polymers show similar removal kinetics as activated carbon and have high capacity (49 mg g<sup>–1</sup> of CHCl<sub>3</sub>). Furthermore, these materials maintain their performance in real drinking water and can be thermally regenerated under mild conditions. Cavitand polymers also outperform activated carbon in their adsorption of 1,4-dioxane, which is difficult to remove and contaminates many public water sources. These materials show promise for removing toxic organic micropollutants and further demonstrate the value of using supramolecular chemistry to design novel absorbents for water purification.<br></p>
