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.

Hydraulic Behavior

Occurrence of extreme hydroclimatological events associated with climatic variability and climate change, along with deficient development of urban drainage systems, have increased the occurrence of floods in cities. This study analyzes the hydraulic behavior of the urban drainage system in the east of Cali, during the occurrence of maximum rainfall events, supported by the Storm Water Management Model. Three simulation climate scenarios were developed: (i) current scenario with a return time of 2 and 10 years, (ii). a climate scenario for the year 2030 and (iii) a climate scenario for the year 2040. The model presented an acceptable grade of calibration, with a Nash-Sutcliffe number greater than 0.5 in simulated events, therefore the results obtained appropriately describe the behavior of surface runoff in the study area, in terms of spatial and temporal resolution. In this way, critical points of the drainage system were identified. This information may be potentially useful in the planning of future hydraulic works, leading to an improvement of the hydraulic behavior of the system, and the protection of life and property of the inhabitants of the city.

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

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.
