This document summarizes a student project using HEC-HMS software to model rainfall runoff. The project aims to study and simulate the rainfall runoff process, learn how to use the modeling software, prepare a draft model, and compute and model runoff. Key aspects of the model include subdividing the area into sub-basins representing different land uses like residential and cultivated areas, inputting precipitation data and metrological models, using the SCS curve number loss model to compute losses, and running a simulation to output results.
HEC-RAS is a computer program that models the hydraulics of water flow through natural rivers and other channels. The program is one-dimensional, meaning that there is no direct modeling of the hydraulic effect of cross section shape changes, bends, and other two- and three-dimensional aspects of flow. The program was developed by the US Department of Defense, Army Corps of Engineers in order to manage the rivers, harbors, and other public works under their jurisdiction; it has found wide acceptance by many others since its public release in 1995.
A study confined to the lower tapi basin in Gujarat, India to find out the primary causes for 2006 floods in Surat city. The study involves collection of topographical data from the local geological survey organization, rainfall data from meteorological department of india and the application of HEC-HMS software from US Army corps of engineers to identify the primary cause of the runoff.

Due to climate change it is very essential to do hydrological modelling. Reliable models are essential for planning,
developmental works, prediction and safety of the population. Hydrological models are used to determine catchment
discharge/flow through an efficient way. HEC-HM (Hydrological engineering centre Hydrological modelling system) is
one of hydrological modelling tool developed by United States army corps of engineer (USACE) for event as well as for
continuous simulations. Models, especially continuous simulations are useful for future predictions of stream flow due to
land-use changes or extreme events phenomenon. In this study continuous hydrologic modellingwas carried out using
HEC HMS modelling tool.
Deficit and Constant Loss methods with Clark transform methods were selected. The calibrated model (period
1986-1988) was validated with data set of the period of 2009-2013. Study concluded that the model recommended and
can be used for stated River as decision support tool in the design and operation.

This narrated PowerPoint presentation describes a HEC-RAS 2-D unsteady-flow flood model set up for the tidally-influenced Little River in Newburyport and Newbury, Massachusetts. It describes the steps in developing inputs to the HEC-RAS model including using HEC-HMS rainfall-runoff modeling and GIS in developing inputs to HEC-HMS. The HEC-RAS model was calibrated using the Mother's Day flood of May 2006. The HEC-RAS model may be used to evaluate impacts associated with proposed changes in culvert sizes or changing embankment elevations near or at problem flood areas and can also be used to determine the changes in river hydraulics associated with sea level rise and climate change.

Abstract. This talk is about the GEOtop and JGrass-NewAge model, their physical bases, their informatics based on older (the first) and new (the latter) programming paradigms, the lessons I learned in building them with my group of people in an academic environment, their future, and the understanding that there is no the best model, but certainly a better way to do models.
Hydrological modelling was for long time, and still is, almost a synonym of simulating rainfall-runoff. Recently, however, the scope of hydrology became wider, even among engineers. Modelling in hydrology now certainly still means modelling discharges, but also modelling snow, evapotranspiration and turbulent exchanges, and surface/subsurface interactions. With the goal of reproducing the whole picture of the terrestrial hydrological fluxes, my coworkers and I worked together in the last decade to build new models and new types of models. We started from the lesson by P. Eagleson, and we built first the process-based (grid based) GEOtop model. GEOtop is “terrain-based” (it is based on the use of digital terrain models and uses the knowledge of interaction between morphology and process) “distributed” (all the simulated variables are calculated for each pixel of the basin) model of “the water cycle” (it simulates all the components of the water cycle, accounting for both the mass budget and the energy budget, the two budget equations being coupled through the temperature of the soil, which controls evaporation, hydraulic conductivity, and accumulation of the snowpack). However, this GEOtop was intimidating many, either for the complexity of the process and its internals, and possibly not adapted to large scale modelling where faster solutions are required.
Therefore we also worked on a different, more parsimonious model, called JGrass-NewAGE. From the lesson learned by implementing and maintaining GEOtop, we also found necessary to build the new model on new informatics. This system sacrifices process details in favour of efficient calculations. It is made of components apt at returning statistical hydrological quantities, opportunely averaged in time and space. One of the goals of this implementation effort was to create the basis for a physico-statistical hydrology in which the hydrological spatially distributed dynamics are reduced into low dimensional components, when necessary surrogating the internal heterogeneities with "suitable noise" and a probabilistic description. Unlike other efforts of synthesis, JGrass-NewAge keeps the spatial description explicit, at various degrees of simplicity. This has been made possible by opportune processing of distributed information which, in this way, has become part of the model itself.

This is our presentation in Mashrouy IV competition. Mashrouy IV is a competition sponsored by British Council in Sudan. We have reached the top 12 projects--we still there BTW. Hopefully, we will get a better position.
A major challenge in hydrological modelling is to identification of optimal
parameter set of different data, catchment characteristics and objectives. Although, the
identification of optimal parameter set is difficult because of conceptual hydrological
models contain more number of parameters and accuracy also depends upon all the
relevant number of parameters influencing in a model. This identification process
cannot estimate directly and therefore it measured based on calibrating the model
which minimizing an objective function. Here, the objective function can depend upon
the sensitivity of model parameters and calibration of model. In this paper, we proposed
the Emulator Based Optimization (EBO) for reducing number of runs and improving
conceptual model efficiency. Where, emulator models are used to represent the
response surface of the simulation models and it can play a valuable role for
optimization. In this study evaluates EBO for calibrating of SWAT hydrological model
with following steps like input design, simulation model, emulator modelling,
convergence criteria and validation. The results show that EBO calibrates the model
with high accuracy and it captured the observed model with consuming less time. This
study helps for decision making, planning and designing of water resources.
