https://iesj.ft.uns.ac.id/iesj <p>The<strong> Innovative Engineering and Sustainability Journal</strong> (IESJ) was established with the strong spirit of collaboration between the <a title="Faculty of Engineering, UNS" href="https://ft.uns.ac.id/"><strong>Faculty of Engineering, Universitas Sebelas Maret (UNS), Indonesia</strong></a>, and the <a title="School of Engineering, KMITL" href="https://engineer.kmitl.ac.th/"><strong>School of Engineering, King Mongkut's Institute of Technology Ladkrabang (KMITL), Thailand</strong></a>, on 14 September 2021.</p> <p><strong>The Innovative Engineering and Sustainability Journal</strong> aims at promoting research and innovation on applied engineering, sustainable technology, and environmental sustainability that promote sustainable development in Southeast Asian countries. This journal serves as one of the outlets for the research and innovation of these fields. </p> <p>The scope of the journal includes, but is not limited to, innovative theories and applications in civil engineering, electrical engineering, mechanical engineering, water resources engineering, environmental engineering, biomedical engineering, instrumentation engineering, urban engineering, cross-cutting issues of technology and sustainability, with the focus area are particularly in Southeast Asia and Asia. </p> <p>The Journal adopts a peer-review process and upholds the liberty of academic principles, academic and scientific ethics, as well as publishing ethics. The Journal does have zero tolerance for plagiarism.</p> <p>This is an open-access and peer-review journal that applies no article processing charge. The journal publishes the selected articles in English two times a year in June and December. </p> Faculty of Engineering UNS and School of Engineering KMITL en-US Innovative Engineering and Sustainability Journal 2829-3010 https://iesj.ft.uns.ac.id/iesj/article/view/9 <p>There are many parameters of the watershed that govern the hydrologic responses in the process of rainfall-runoff process. One of the parameters is geomorphological parameters. Some parameters have been well known for their contribution to streamflow discharge, the other parameters do not. We explore some geomorphological parameters that strongly influence the hydrologic response of a watershed but received inadequate attention to be investigated and discussed. We refer to a rainfall-runoff model in which rainfall is the primary input parameter and runoff in the stream is the output. By identifying a number of rainfall-runoff and other hydrologic models, the data parameters required to run the mode and obtain the output i.e. flood could be identified. We concluded that the watershed parameters of the hypsometric curve, watershed shape, drainage density, channel length, channel slope, channel cross-section, Horton’s stream, and degree of meandering, are important watershed parameters but lack attention from scholars.&nbsp;&nbsp;</p> AS Permana Sholihin As'ad Cahyono Ikhsan Copyright (c) 2022 The copyright holders of all published articles are at Author and Journal. https://creativecommons.org/licenses/by-nc-nd/4.0 2022-12-27 2022-12-27 1 2 50 60 https://iesj.ft.uns.ac.id/iesj/article/view/4 <p>Floods may bring in both negative and positive impacts to society, the positive impacts, for example, in Nile river delta. In the Surakarta City, the floods bring largely negative effects, sometime loss of life. Urban floods of Surakarta City are so far caused by two generic proceedings of exceedance of river capacity and lacks of urban drainage. It has been exacerbated by the incompatibility of communities’ activities with respect to flood. Inadequate flood prevention facilities have also been the trigger to urban flood in the city. The climate change may be one of the causes as well. However, we have no data to measure the contribution of this global phenomenon on the local urban flood. This study investigates the depth and duration of the inundated urban lands due to floods of the prominent tributaries of Bengawan Solo River in Surakarta City, since these variables determine the extent of the impacts and losses. These two variables were determined from the running of HEC-RAS river analysis program, with the inputs of hydrographs for particular flood return period along with geographical data of the city. The results show that inundation depth could reach a height of up to 4.0 m, varying with the duration.</p> R Hadiani S As'ad AS Permana Copyright (c) 2022 The copyright holders of all published articles are at Author and Journal. https://creativecommons.org/licenses/by-nc-nd/4.0 2022-12-29 2022-12-29 1 2 61 72
