Abstract

Flooding is a natural phenomenon in the form of water inundating land and can cause harm to humans. Floods can be caused by high rainfall, limited riverbed capacity, and topography and drainage conditions. One of the rivers that causes flooding in the city of Padang is the Batang Kuranji (Kuranji River), especially in the downstream part. Therefore, an environmentally friendly flood control system is needed that can reduce flood peaks downstream, namely by creating several retention ponds. This research was conducted to examine the effect of serial retention ponds on reducing flood peaks in the middle section of Batang Kuranji. Retention ponds are placed on the left and right sides of the river on the section from the Gunung-Nago weir to the Kuranji Bridge on the Padang-Bypass road. The estimated flood discharge in the Gunung-Nago Sub-watershed is 547 m3/s for a 10-year return period with a watershed area of ​​124 km2. The series retention pond simulation appears to be very effective in reducing peak flood discharge by 52% with a pond area of ​​0.8 million m3. Even though the return period is 100 years, the effectiveness percentage is 34%. Suggestions to stakeholders so that the pond can function properly require regular maintenance and dredging,

Abstract

This study investigated the flow and sedimentation patterns at a series of check dams on the Kuranji River. A physical model was built in the laboratory at a specific scale to simulate field conditions. The models were built using an approach to existing conditions with a dam height scale of 1:125 while the check dam spacing was 1:300 while the field condition spacing between check dams of scenario 1 (89.00 cm), scenario 2 (94.00 cm), scenario 3 (200 cm). All models were conducted in a 40 x 40 cm rectangular open channel in the laboratory of Fluid Mechanics and Hydraulics, Faculty of Engineering, Andalas University, Padang. Sediment material was used from the Kuranji Trunk. Furthermore, each experiment with variations in flow discharge was observed and measured the sediment distribution pattern before and after the check dam building. From the test results, it was found that the sediment balanced condition ranged from 10-19 minutes after the water came out of the dainhole. Sediment distribution patterns are influenced by two main factors, namely the distance between check dams and flow discharge. The use of too far a distance results in sediment having a greater chance of moving away downstream, on the other hand, with a close distance between check dams, the sediment distribution moves not too far. Discharge variations affect the scouring depth. The greater the flow discharge, the greater the energy to scour and carry the greater sediment.

Abstract

This study compares evapotranspiration (ETo) values obtained from direct field observations with estimates from empirical models at different elevation. The empirical models used are Modified Penman, Penman-Monteith, Blaney-Criddle, Hargreaves, and Radiation. This research was conducted in the Batang Kuranji Watershed, specifically in Pauh Subdistrict (174 m above sea level) and Nanggalo Subdistrict (18 m above sea level), from August 6th to August 31st, 2023. Daily temperature, humidity, wind speed, and solar radiation data, collected using Thermo-Pro devices and from relevant agencies, were used as input for the empirical models. Three field experiments were carried out in the form of: evaporation plots, evapotranspiration plots without infiltration influence, and evapotranspiration plots with infiltration influence. Furthermore, the observed ETo values in the field were 90.67 mm/month in Nanggalo and 90.00 mm/month in Pauh. The empirical models produced estimates comparable to field observations. Analysis of the coefficient of determination (R²) revealed that the Modified Penman empirical model was the most suitable with field experiments and showed a very strong relationship (R² = 0.96). The results of this study can be used as a basis for managing rice irrigation water and developing better ETo prediction models, especially in the Batang Kuranji Watershed. The authors identify areas needing further research to enable the model's use for calculating evaporation across an entire growing season.

Abstract

Indonesia has high rainfall, which often causes flooding. Large volumes of rainwater cause sediment in river channels to move from upstream to downstream. The shape of rivers in Indonesia tends to bend, so the researcher conducted a study of the turning channel using a check dam structure with three placement conditions, namely before the bend, in the middle of the bend, and after the bend. This research was conducted at the Fluid Mechanics and Hydraulics Laboratory, Department of Civil Engineering, Faculty of Engineering, Universitas Andalas, Padang. This study aims to determine the impact of sediment on erosion caused by the placement of check dams on river bends and to determine the distribution of sediment due to changes in the position of Check Dam buildings on river bends. A 12.8 m long channel, made of 5 mm acrylic, with a cross section of 0.4 m x 0.4 m and a bend angle of 120o, was used in the experiment. Researchers measured flood discharge and sediment distribution for each of the three check dam positions. The study showed that the sediment distribution varied significantly depending on the location of the check dam. The researchers observed that the most balanced sediment distribution, with relatively equal deposition on the inner and outer sides of the bend, occurred when the check dam was placed after the bend. Based on these findings, they recommend placing check dams after bends in meandering rivers to minimize erosion and promote a more balanced sediment distribution.

Abstract

The magnitude of the longitudinal slope of river gratly determines the magnitude of sediment transport. This is due to the large flow velocity. This shape causes gradation of the river bed, especially upstream of the river. This phenomenon is seen in the middle segment of Batang Kuranji. where a sediment control buildg or check dam has been built. However, sediment transport and changes in river cross-section upstream still occur. Based on this phenomenon, a simulation of changes in flood discharge on sediment rate was carried out. This simulation was carried out using the Meyer Peter Muller method found in HEC-RAS 6.0.0. The simulation was carried out using 25 year planned flood discharge with smaller variations in discharge changes, namely Q1, Q2 and Q3. In general, the simulation results show that changes in flood discharge determine the magnitude of changes in sediment rates, the greater the flow discharge, the higher the sediment rate, both with and without check dams. The simulation results also show that the sediment rate in conditions with a check dam has decreased compared to conditions without a check dam, this shows that the presence of a check dam can reduce the sediment rate that occurred before the check dam was built.

Abstract

The availability of hydrological data is one of the challenges associated with developing water infrastructure in different areas. This led to the TRMM (Tropical Precipitation Measurement Mission) design by NASA, which involves using satellite weather monitoring technology to monitor and analyze tropical precipitation in different parts of the world. Therefore, this validation study was conducted to compare TRMM precipitation data with observed precipitation to determine its application as an alternate source of hydrological data. The Kuranji watershed was selected as the study site due to the availability of suitable data. Moreover, the validation analyses applied include the Root Mean Squared Error (RMSE), Nash-Sutcliffe Efficiency (NSE), Coefficient Correlation (R), and Relative Error (RE). These used two calculation forms: one for the uncorrected data and another for the corrected data. The results showed that the best-adjusted data validation from the Gunung Nago station in 2016 was recorded to be RMSE = 62,298, NSE = 0.044, R = 0.902, and RE = 11,328. The closeness of the R-value to one implies that the corrected TRMM data outperforms the uncorrected ones. Therefore, it was generally concluded that the TRMM data matches the observed precipitation data and can be used for hydrological study in the Kuranji watershed
