On a global scale, with the acceleration of urbanization and the continuous expansion of cities, the problem of urban flooding has become increasingly prominent. An increasing number of experts and scholars have begun to focus on this phenomenon and build corresponding models to solve the problem. The storm water management model 5 (SWMM5) is a dynamic rainfall-runoff simulation model developed by the US Environmental Protection Agency (EPA); this model simulates urban flooding and drainage well and is widely favored by researchers. However, the use of SWMM5 is relatively cumbersome and limited by the operational platform, and these factors hinder the further promotion and sharing of SWMM5. Based on the OpenGMS platform, this study first encapsulates, deploys, and publishes SWMM5 and further builds the Web-SWMM system for the model. With Web-SWMM, the user can conveniently use network data resources online and call SWMM5 to carry out calculations, avoiding the difficulties caused by the localized use of SWMM5 and enabling the sharing and reuse of SWMM5.

Tataguna  lahan  di  Sub  Daerah  Aliran  Sungai  (DAS)  Banjaran  telah mengalami perubahan yang cukup tinggi selama  kurun  waktu  1995  sampai  2001. Lahan sawah berkurang 1.759,28 hektar menjadi 1.603,97 hektar, tegalan berkurang  289,54 hektar menjadi 283,32 hektar dan permukiman bertambah 1.284,36  hektar menjadi 1.445,88 hektar. Alih fungsi lahan ini mengakibatkan banjir sering terjadi. Beberapa kali Sungai Banjaran meluap menyebabkan banjir di permukiman dan ruas jalan. Kajian pengaruh perubahan lahan terhadap debit banjir perlu dilakukan sehingga peningkatan debit banjir dapat dikendalikan.Tujuan penelitian ini menganalisis debit banjir secara periodik sesuai dengan perubahan tata guna lahan yang terjadi berdasarkan data hidrologi dan parameter DAS. Perhitungan debit banjir dilakukan dengan kalibrasi Environmental Protection Agency – Storm Water Management Model( EPA-SWMM), yaitu metode Hidrograf Observasi (debit terukur) yang  dikalibrasi dengan metode Nash. Analisis perubahan lahan menggunakan peta tataguna lahan tahun 2005, Citra Satelit Quick Bird tahun 2010 dan 2014 yang berbasis Geography Information System (GIS). Penggunaan citra satelit resolusi tinggi Quick Bird  memenuhi ketepatan dalam menentukan daerah impervious dan pervious sertamorfometri DAS sebagai parameter utama dalam input EPA-SWMM. Model yang telah terkalibrasi digunakan untuk simulasi debit rencana  sampai periode ulang  50  tahun.Perubahan  lahan  selama tahun  2005-2014  permukiman meningkat sebesar 10,98 ha (2,39 %), luas hutan menurun 1,67 ha (0,07%), telah mengakibatkan kenaikan debit banjir Q2  sampai Q50  tahun. Besarnya debit dan kenaikannya berturut-turut sebagai berikut : Q2  tahun sebesar 3,08 m3/dtk (2,16 %), Q5 tahun sebesar 3,5 m3/dtk (1,87 %), Q10 tahun sebesar 3,72 m3/dtk (1,7 %), Q25 tahun sebesar 3,94 m3/dtk (1,60 %) dan Q50 tahun sebesar 4,13 m3/dtk (1,50 %).  Volume banjir terjadi peningkatan yakni: Q2 tahun sebesar 0,57 % (10. 106 ) liter, Q5 tahun sebesar 0,45 % (12.106 ) liter, Q10 tahun sebesar 0,42 % (13. 106) liter, Q25 tahun sebesar 0,33 % (12.106) liter dan Q50 tahun sebesar 0,35 % (14.106) liter. Usaha pengendalian banjir pada periode ulang 50 tahun (Q50) yang disimulasikan mampu menurunkan debit banjir antara lain : penegakkan hukum  sebesar 14,43 m3/dtk (5 %), embung sebesar 20,9 m3/dtk  (7,1 %) dan sumur resapan sebesar 31,18 m3/dtk (10,73 %). Skenario RTRW sebesar 26,3 m3/dtk (9,05 %), kombinasi sumur resapan dan penegakan hukum sebesar 45,92 m3/dtk (15,81 %) dan kombinasi embung dan penegakan hukum sebesar 40,58 m3/dtk (13,97 %). Dari hasil simulasi diperoleh pembuatan sumur resapan, kombinasi sumur resapan dan penegakan hukum, kombinasi embung dan penegakan hukum mampu menurunkan debit banjir sampai pada Q25

RESUMO: As inundações urbanas estão se tornando cada vez mais frequentes, de tal forma que a União Europeia publicou a Diretiva 2007/60/CE no sentido de mitigar as consequências relacionadas com este fenômeno e de impor limites à concentração de poluentes nas águas pluviais. O objetivo deste artigo foi apresentar uma modelação dos sistemas de drenagem em situação de inundações, baseada no software da United States Environmental Protection Agency (EPA), Storm Water Management Model (SWMM), em que o estudo de caso é analisar um sistema de drenagem urbana unitário, inserido na Zona Central de Coimbra, em Portugal. Recorrendo à metodologia Automatic Overland Flow Delineation (AOFD) para a geração de uma rede de drenagem superficial e implementando-a no SWMM, obteve-se um modelo de drenagem dual, que permite a análise do escoamento em situação de inundações, incluindo o controle de escoamento entre a superfície e a rede de coletores e a modelação da qualidade da água à superfície. Este modelo permite quantificar a carga poluente à superfície, relativamente ao parâmetro de sólidos suspensos totais, para um evento de precipitação extrema.

Drainage Channels

Tarakan City experiences problems with standing water during the rainy season, especially in the west Tarakan sub-district which is the center of Tarakan. This puddle not only submerged settlements and offices but also shops and access roads that caused considerable economic losses. An evaluation was carried out by using the Storm Water Management Model (SWMM). SWMM is a rainfall-runoff simulation model used for simulating the quantity and quality of surface runoff from urban areas. Based on the evaluation using SWMM software, the drainage system in Tarakan, especially in Jalan Mulwarman has several inundated channels, namely channels 2, 3, 4, 5, 6, 7, 11, 12, 13, 14. This is influenced by the dimensions of the drainage channel that cannot accommodate existing water runoff and sediment thickness that covers the drainage channels so that the capacity is reduced, if it rains it will cause puddles at several points in Tarakan City. In order to deal with these puddles, it is necessary to change the dimensions of the channel and routinely dredge sediments that cover the drainage channels.
