“…The models are not biased in over predicting or under predicting the simulated runoff [1], [2], [8], [9], [10] and [19]. Consistently high performance results are obtained from GIUH models as compared to SWAT models used by [11], [12], [14] and [17]. The method used for simulation at ungauged catchment of different sites varies.…”

“…Relapse and physical comparability approach created practically identical outcomes, and the model proficiency is satisfactory. Iskender and Sajikumar [12] attempted to relate the execution of Soil and Water Assessment Tool (SWAT) and Geomorphologic instantaneous unit hydrograph (GIUH) modeling to forecast a superficial runoff for the instance of occasion displaying utilizing sub day by day precipitation and overflow. In view of model execution correlation, it is discovered that reliably better outcomes obtained from the GIUH models.…”

Ungauged catchment occurs when no runoff data are available or when very few ground rain gauges are located in a huge catchment. For these catchments, the parameters to be used in rainfall‐runoff models cannot be attained just by adjusting runoff information and thus should be procured by different techniques. Show parameters that require orientation are normally transposed from comparable measured catchments. The rainfall runoff simulation is very important to estimate and predict the flow in ungauged catchment. This investigation reviews ideas to differentiate hydrological comparability for transposing parameters from a gauged to an ungauged catchment. Model parameters that are physically based are generally derived from other information close to the ungauged catchment of intrigue. The primary challenge with rainfall‐runoff demonstrating in ungauged catchments is the absence of neighborhood ground precipitation and streamflow information to be utilized in aligning the proposed show parameters. Parameter alignment is useful since adjustment can represent the impacts of hydrological set up in a specific catchment. Since hydrological models are especially reliant on their limit conditions, the alignment practice directed can modify the predispositions of info information utilized. Parameters' adjustment can fundamentally improve the execution of rainfall‐runoff models since it included media properties of soil and vegetation which are exceptionally heterogeneous and basically are in every case inadequately known. Alternative methods for ungauged catchments are required which are the subject of this study. This study summarizes the important methods used in an ungauged catchments, discusses the issues of using satellite data as a substitute input to rainfall‐runoff models and its comparison with point scale ground data.

“…This model combines the geomorphological characteristic of a watershed and its corresponding response due to rainfall events [14,16,17]. Rodriguez-Iturbe and Valdez [11] assumed that the instantaneous unit hydrograph has a triangle form consisting of peak discharge (qp), peak time (t p ), and base time (t b ) [4,18,19]. The triangular parameter of GIUH is illustrated in Figure 3, whereas the equations are written as follows:…”

Understanding the rainfall-runoff response on a watershed requires the study of both the observed and synthetic unit hydrographs. The application of a synthetic unit hydrograph for an ungauged watershed is the prospective alternative. Model development to obtain the unit hydrograph without rainfall and runoff data requires information on the physical characteristics of the watershed and its geomorphological parameters. This paper presents the results of a study on the application of the Geomorphological Instantaneous Unit Hydrograph (GIUH) model in which the time of concentration equations of Kirpich and Ventura were used as a comparison. The study objects are the Keduang and Temon Sub-watersheds of the Upper Bengawan Solo River, Indonesia. The study utilized the sub-watershed characteristic data obtained from the satellite data of ASTER Global DEM V3, which was then processed with the Watershed Modeling System and ArcMap. The results show that in the Keduang Sub-watershed, the Ventura equation gave results closer to the observed unit hydrograph than the Kirpich equation. In the Keduang Sub-watershed, the differences between the two times of concentration on the triangular parameters were significant, i.e. 77.13%, 337.57%, and 338.20% for peak discharge, peak time, and base time, respectively. On the other hand, in Temon Sub-watershed, the differences were 33.88%, 28.63%, and 25.09% for peak discharge, peak time, and base time, respectively. In terms of the GIUH-based flood hydrograph estimation, the results show that the utilization of the Ventura equation generally led to better estimates (closer to the observed flood hydrograph) than that of Kirpich equation.

“…Unit hydrographs, either synthetic or instantaneous, have been intensively used to predict runoff in some studies. Such unit hydrograph is capable to improve runoff prediction [2], even in ungauged catchment [3][4][5] or gauged catchment [6], dealing with the parameters of the unit hydrograph to achieve a better runoff prediction [7], evaluating runoff prediction using unit hydrograph and physicallybased model [8]. A conceptual model such as a bucket model is not only capable to predict runoff in a catchment [9][10][11] but also in a catchment with lakes ( [12,13]).…”

This study is motivated by floodings which occur frequently in Jagabaya village, Way Awi catchment, Bandar Lampung city, Indonesia. In addition to the intensity of rainfall, this area is considered as an urban area with intense housing and insufficient drainage capacity during heavy rain. This study aims to analyze flood peak reduction by simulating the application of rain barrels for each house. The volume of rain barrels used in the simulation is 0.5 to 5 m 3 . An Intensity-Duration-Frequency (IDF) curve is generated using short-duration rainfall data (i.e. 5, 10, 15, 30, 60, 120, 180, 360 and 720 minutes) recorded from Panjang Meteorological Bureau, Lampung. The rational method, a simple rainfall-runoff model, is used to calculate runoff generated both from catchment and rooftop. The result shows that the application of rain barrels may reduce flood peak up to 28% for 2 year return period of flood, while for 100 year return period of flood, the reduction may reach 13.64%. From this study, it can be concluded that rainwater harvesting utilizing rain barrel is significant in reducing flood peak. Furthermore, this result can be used to persuade both the society as well as the local government to do such flood mitigation in this densely populated urban area.
