The problem of flood inundation in the Kebon Agung River at the Medokan Ayu Village, Rungkut District Surabaya, is getting worse due to the conditions of topographic, soil properties, high rainfalls, rising sea tides and very significant changes in land use. The eastern part of Surabaya, which was formerly open space land and now developed into a residential area. Therefore in the area, there is often flood inundation when the rainy season due to lack of recharge areas and poor drainage facilities. The performance evaluation of the drainage system was carried out using the SWMM program that is combining hydrology and hydraulic analysis. Hydrology analysis is used to determine various rainfall return periods. The maximum rainfall data are collected for 18 years. The hydraulic analysis is used to obtain the data in the form of cross-section, roughness, and drainage channel capacity. The results of the evaluation of drainage system modeling with SWMM have obtained the inundation points, namely for channels K3-K4-K5- K6-K7-K8 on the right side and Ki2-Ki3-Ki4-Ki5 on the left side. Pemasalahan genangan banjir di Kali Kebon Agung di Kelurahan Medokan Ayu Kecamatan Rungkut Surabaya menjadi semakin parah karena kondisi topografi, sifat tanah, tingginya intensitas hujan, meningkatnya pasang surut air laut dan perubahan tata guna lahan yang sangat signifikan. Wilayah Surabaya bagian timur yang semula lahan terbuka kini berkembang menjadi daerah perumahan. Oleh sebab itu di wilayah tersebut sering terjadi genangan banjir saat musim hujan dikarenakan kurangnya daerah resapan dan fasilitas drainase yang kurang baik. Evaluasi kinerja sistem drainase pada wilayah tersebut dilakukan dengan menggunakan pemodelan SWMM yang megabungkan pemodelan hidrologi dan hirdolika. Analisis hidrologi digunakan untuk menentukan berbagai kala ulang hujan. Data curah hujan maksimum digunakan selama 18 tahun. Analisis hidrolika digunakan untuk memperoleh data berupa penampang, kekasaran, dan kapasitas saluran drainase. Hasil running SWMM didapatkan titik titik lokasi genangan pada saluran K3-K4-K5-K6- K7-K8 pada sisi kanan dan Ki2-Ki3-Ki4-Ki5 pada sisi kiri.

Sidoarjo or Lusi mud has an area of ​​640 ha and an average embankment height of 10 meters and submerges three sub-districts, namely Porong District, Jabon District and Tanggulangin District. In 2018, the Sidoarjo mud embankment has decreased or subsided by up to 8.5 meters at several points, which was caused by the condition of the embankment which was almost full and caused the soil condition of the embankment to become unstable. For this problem, it is necessary to build a drainage channel at the edge of the embankment to overcome the overflow of the embankment and flow it to the Porong river which is on the south side of the Sidoarjo mud embankment. From the calculation of the planned rain discharge, it is found that R2 = 72.95 mm after the planned rainfall is obtained, then the next is to look for the flood discharge plan which then plans the dimensions of the channel on the west and east sides of the embankment after obtaining the dimensions of the channel, then the next is planning the resistance pond and draining it to the porong river. with Siphon Network Pipe

The purpose of chest drainage is to allow lung re-expansion and the reestablishment of the subatmospheric pressure in the pleural space. Properly managing the drainage system minimizes procedure-related complications. This prospective observational study evaluated adult patients undergoing water-seal chest drainage, admitted to our hospital and accompanied by residents and tutors, aiming to check their care. One hundred chest drainages were monitored. The average age was 38.8 years old. The average drainage time was 6.7 days. Trauma was the prevalent cause (72%) for the indication of pleural drainage. The obstruction of the system occurred in 6% of the cases; 5% subcutaneous emphysema, 1% infection around the drain; 5% accidental dislodgement of the drain, and in 5% of the patients, there were some complications when removing the drain. Failures in chest drainage technique and management were present, and reflected in some complications that are inherent to the procedure, although it is known that there are intrinsic complications. This study aimed to assess the management of closed chest drainage systems and standardize the care provided in such procedure.

AbstractStudy of borehole data in the foothill region of the Jabal Nafusah shows that the Suq al Jum'ah palaeowadi, which cuts the jabal east of Gharyan, comprised a major drainage channel which extended in the subsurface far out from the jabal into the southern part of the Jifarah Plain. The channel is filled with sands and gravels. Basalt lava flows, channelled along the valley in outcrop for 36 km, extend for a further 48 km in the subsurface. The palaeowadi was possibly initiated in the Pliocene and appears to have been completely filled and abandoned by the end of the Pleistocene. During Holocene rejuvenation of the drainage system, the Wadi al Majanin developed as the major wadi in the region. It did not, however, excavate the palaeowadi but instead followed a different but roughly parallel northward trend.

RESUMO: O presente trabalho teve por objetivo delimitar as áreas inundáveis do Córrego Macambira para implantação de um parque linear. Esse curso d'água é objeto de um projeto denominado Programa Urbano Ambiental Macambira-Anicuns com a finalidade de transformar as margens de dois córregos em um parque para população do município de Goiânia-GO. O curso d'água em questão, não diferente dos outros presentes na área urbana, atualmente se encontra degradado e com as áreas de várzea ocupadas desordenadamente por habitações, comércios, pequenas plantações e indústrias. Para a delimitação do perímetro máximo do parque, sua área de abrangência, foi necessário um estudo hidrodinâmico com a delimitação da faixa de inundação das margens do córrego urbano Macambira, em Goiânia, utilizando topografia de alta resolução e o software HEC-RAS. De forma geral, a mancha de inundação obtida para a área em estudo apresentou estar dentro da calha natural inundável do curso d'água na maior parte do tempo. No entanto, alguns pontos ocorrem transbordamentos, que atingem as ruas e locais de áreas habitadas, podendo chegar a até 70 metros a partir da calha natural. Dessa forma, a modelagem por HEC-RAS permitiu contemplar o diagnóstico atual do funcionamento hidrodinâmico do sistema de drenagem do Córrego Macambira com foco no comportamento hidráulico da calha de drenagem existente, servindo de base para o projeto, para que se posa estabelecer estratégias de intervenções eficazes mais apropriadas para cada situação. ABSTRACT: This study aimed to define the flood inundation area of the stream Macambira to implement a linear park. This stream is the subject of a project called Urban Environmental Program-Macambira Anicuns, which aims to transform the banks of these two streams in a public park for the city of Goiania. The stream in question, not different from the others in the urban area, is currently degraded and the floodplain areas occupied by disorderly houses, shops, small industries and plantations. To define the maximum perimeter of the park, its area of coverage, a hydrodynamic study was necessary with the delimitation of flood area of Macambira's urban stream margins, in Goiania, using high-resolution topography and HEC-RAS software. Overall, the flood of band obtained for the study area was flooded in the natural channel of the stream. However, there are overflowing in some points, reaching the streets and places of populated areas, reaching up to 70 meters from the natural channel. Thus, the modeling HEC-RAS allowed contemplate the current diagnosis of the drainage system Stream Macambira, focusing on the hydraulic behavior of the existing drainage channel, providing the basis for the project, so that we can establish effective intervention strategies more appropriate for each situation.

Drainage Channels

A good road drainage system is needed to ensure that road user activities are not disrupted due to rain puddles. The cause of inundation that occurs is land use change, there is no drainage channel, the channel is not well connected, the channel is closed due to widening of the road without considering drainage channels. Given this, research needs to be carried out on the condition of the existing drainage system as a material consideration for evaluating its feasibility and planning a drainage system that is able to overcome the inundation that occurs. Writing this final project refers to primary data and secondary data that already exist. The rainfall data came from the Climatology and Geophysics Meteorological Agency, Balai Besar Region II, Bogor Regency, which is the Darmaga huajn rainfall measurement station and the PUPR Binamarga Office of Bogor Regency. Meanwhile, to find out the dimensions of the existing drainage channels obtained by conducting surveys and direct observation to the field. Data analysis which was carried out was hydrological and hydraulics analysis. Hydrological analysis includes the analysis of rainfall frequency, determining the repeat period, calculating the concentration time, analyzing the rainfall intensity, and calculating the flow flow plan. Based on the results of hydrological analyzes, the hydraulics analysis is then performed, such as calculating the plan channel profile and calculating the height of the planned channel guard. From all of these analyzes, the results of the drainage study on the Cigombong KM 16 - KM 23 highway were carried out, that is, the entire capacity of the existing canals was not able to accommodate the planned flow discharge for a return period of 2 years 5 years 50 years. In addition, the results of the analyzes that have been carried out show that the rain that occurs during a certain period of time and a certain return period greatly affects the planned drainage channel profile and is due to the large amount of garbage in the channel which affects the reservoirs in the drainage that often occur frequently
