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 Impact

Euphrates River extends about 125 km within the study area located in Annassiriyah City, Dhi Qar Governorate, Iraq. The impact of the seven hydraulic structures on the discharge capacity of the Euphrates River needs to be considered. The main objectives of this research are to increase the discharge capacity of Euphrates River within Annassiriyah City during flood seasons and study the impact of these hydraulic structures on the river capacity by using HEC-RAS 5.0.3 software. Five scenarios were simulated to study the different current condition of Euphrates River within Annassiriyah City. Other additional four scenarios were implemented through river training to increase the river capacity to 1300 m³/s; it is the flood of 100 year return period. The results of the current condition showed that the maximum discharge capacity of Euphrates River within Annassiriyah City is just 300 m³/s. The results of applied improvements show that the capacity can reach 1300 m³/s when Al Chibayish Weir was hypothetically removed from the river system. Additionally, the river capacity will be reduced to 600 m³/s when Al Chibayish Weir is considered. It was concluded that the 100-year flood discharge cannot be achieved without removing Al Chibayish Weir from the river system.

Water Overflow

Sawahan is a densely populated sub-district located in the city of Surabaya with a population density which until 2017 reached 215,024 people as a result of a wide and deep drainage channel which became narrow and shallow as more and more settlements developed. And when the rainy season comes, the drainage channel in the Banyu Urip (Simo Katrungan Kidul) area of Surabaya is unable to collect rainwater, causing water overflow in the drainage and flood channels. Heavy rain for more than 1.5 hours and hit Simokatrungan area can cause inundation up to 500 meters inundated. The deepest puddles reach the knees of adults or about 60 cm. The purpose of this study is how to calculate flood discharge and channel dimension planning for the next 2022 planning year. The methods used are hydrological analysis, Existing channel analysis, flood discharge analysis for the next 2 years (2022), and channel capacity for 2022.Based on capacity analysis Secondary Channel Simo Katrungan Kidul Eastern Section is 0.003 m3 / s, while the existing design debit is 0.126 m3 / s, the channel cannot accept the design debit. So the dimensions for this channel are planned to form trapezoidal b1 = 1.3 m. b2 = 1.8 m, h = 1 m. The Northern Tertiary Simo Katrungan Kidul channel capacity is 0.031 m3 / sec, while the existing design discharge is 0.096 m3 / sec. So that the dimensions for this channel are planned to form trapezoid b1 = 1.6 m, b2 = 2.2 m, h = 1.2 m. Simo Katrungan North Section Secondary channel capacity is 0.002 m3 / sec, while the existing design discharge is 0.360 m3 / sec. So that the dimensions for this channel are planned to form trapezoid b1 = 1.6 m, b2 = 2.2 m, h = 1.2 m.

The growth of Gresik City is shown by the development of various infrastructures such as settlements, highways, and others. Along with the growth of Gresik City area, an increase in flood inundation due to increasingly dense settlements, decrease of vacant land as an infiltration area in Tebalo Village. Flooding is caused due to lack of development of drainage systems in the area of Tebalo Village. To normalize Tebalo drainage channel, good planning must be prepared for Tebalo drainage channel system including planning the layout of the channel system, calculating the designed flood discharge for each channel, hydraulics analysis for flood flow conditions and also along high sea water tide conditions, and finally designing the dimensions of the channel. After the channel is normalized, it is expected that the flow would be much smoother so that no flooding occurs.

The Tokyo Metropolitan Government has planned future flood control for a rainfall intensity of 100 mm/hr, which corresponds to a return period of 70 years, and a runoff coefficient of 0.8. Considering that the realization of this plan requires a long construction period and high construction costs, the decision was made to proceed by stages. In the first stage, the improvement of the facilities will be based on a rainfall intensity of 75 mm/hr (presently 50 mm/hr), corresponding to a return period of 17 years, and a runoff coefficient of 0.8. In the next stage the facilities will be improved to accommodate a rainfall intensity of 100 mm/hr. In the Nakano and Suginami regions, which suffer frequently from flooding, the plan of improvement based on a rainfall intensity of 75 mm/hr is being implemented before other areas. This facility will be used as a storage sewer for the time being. The Wada-Yayoi Trunk Sewer, as a project of this plan, will have a diameter of 8 m and a 50 m earth cover. This trunk sewer will be constructed considering several constraints. To resolve these problems, hydraulic experiments as well as an inventory study have been carried out. A large drop shaft for the trunk sewer is under construction.
