Abstract:
An effort was made to develop a mathematical model using unit-step and transfer functions approach for Karkara watershed of Tilaiya dam catchment in Upper Damodar Valley of Jharkhand State of India for estimating direct runoff hydrographs on storm basis. The model used rainfall data in blocks of finite duration represented by unit step function. The outflow hydrograph ordinates were obtained by taking inverse Laplace transform of product of Laplace transforms of the transfer function (Laplace transform of Instantaneous Unit Hydrograph) and the input (effective rainfall).

Abstract. This paper addresses the mass balance error observed in runoff hydrographs in urban watersheds by introducing assumptions regarding the contribution of infiltrated rainfall from pervious areas and isolated impervious area (IIA) to the runoff hydrograph. Rainfall infiltrating into pervious areas has been assumed not to contribute to the runoff hydrograph until Hortonian excess rainfall occurs. However, mass balance analysis in an urban watershed indicates that rainfall infiltrated to pervious areas can contribute to direct runoff hydrograph, thereby offering an explanation for the lon

Abstract:
This study investigates the comparative performance of event-based and continuous simulation modelling of a stormwater management model (EPA-SWMM) in calculating total runoff hydrographs and direct runoff hydrographs. Myponga upstream and Scott Creek catchments in South Australia were selected as the case study catchments and model performance was assessed using a total of 36 streamflow events from the period of 2001 to 2004. Goodness-of-fit of the EPA-SWMM models developed using automatic calibration were assessed using eight goodness-of-fit measures including Nash–Sutcliff efficiency (NSE),

Gamma distribution function can have variety of shapes including single peaked positively skewed graph having unit area under the curve, which perfectly matches the graphical presentation of unit hydrograph. The shape and scale parameters can be evaluated from the observed peak runoff rate and time to peak duration by iterative method.

The hydrologic data of 452.25 km2 Chaukhutia watershed of Ramganga reservoir catchment in Uttarakhand was analyzed to develop unit hydrograph model using the extreme value type-I distribution function. The parameters of the model were determined by method of moments. The direct runoff hydrographs were developed by convolving effective rainfall values with one-hour unit hydrograph (I-hUH) for evaluating the prediction performance of the model.

A geomorphologic instantaneous unit hydrograph (OIUH) model, based on kinematic-wave and stream order ratios, has been developed to predict the direct runoff hydrograph from a hilly sub-watershed of Ramganga river catchment in Uttaranchal (India). The travel times for overland and stream flows in a stream-ordering system of the watershed have been determined analytically and probabilistically to derive the OIUH, without using the past record of rainfall and runoff data.

Abstract. The understanding of runoff generation mechanisms is crucial for the sustainable management of river basins such as the allocation of water resources or the prediction of floods and droughts. However, identifying the mechanisms of runoff generation has been a challenging task, even more so in arid and semi-arid areas where high rainfall and streamflow variability, high evaporation rates, and deep groundwater reservoirs increase the complexity of hydrological process dynamics. Isotope and hydrochemical tracers have proven to be useful in identifying runoff components and their charact

Rainfall-Runoff modeling is among the classical applications of hydrology. This paper examines the results of 3 hydrologic approaches, particularly Clark Model, Nash Model, and Geomorphic Instantaneous Unit Hydrograph Model. Assumptions are forwarded for the long run use of the Rawalpindi Division, Pakistan’s Small Dam Organization. The catchment of Shahpur Dam was an area under consideration for the study. The Digital elevation model (DEM) was implicated to measure the Nash and Clark model’s geomorphic parameters. Using ArcGIS, catchment satellite imagery was processed to estimate geomorpholo

Abstract:
This report deals with rainfall-runoff modeling and small water reservoir projection with usage of modern software equipments (GIS, HEC-HMS), using maximum number of available data sources (BPEJ, LPIS, N-year rainfall gages, 3D contours …). The advantage of this method is that it is possible to predict the shape of hydrograph and flood wave volume as well. Other methods cannot offer judgment of flood wave volume and hydrograph shape as this method does. The most important thing in small water reservoir projection is the flood wave volume value, which is undervalued nowadays using wrong evaluat

Abstract:
A surge function is a mathematical function of the form f(x)=axpe-bx. We simplify the surge function by holding p constant at 1 and investigate the simplified form as a potential model to represent the full peak of a stream discharge hydrograph. The previously studied Weibull and gamma distributions are included for comparison. We develop an analysis algorithm which produces the best-fit parameters for every peak for each model function, and we process the data with a MATLAB script that uses spectral analysis to filter year-long, 15-minute, stream-discharge data sets.

The later two factors affect discharge by increasing or decreasing storage. However, unit hydrograph (UH) and other traditional black-box rainfall-runoff models assume direct runoff respond linearly to excess rainfall intensity. The effect of storage within the watershed is not considered in UH, and the linear assumption does not really valid in a water
