The basic principles underlying the most commonly used physically-based models of the rainfall-runoff transformation process are reviewed. A thorough knowledge of these principles is a pre-requisite for flood hazard studies and, thus, this chapter reviews several physically-based methods to determine flood discharges, flow depths, and other flood characteristics. The chapter starts with a thoro...

Design flood estimation is often required in engineering practice such as design of hydrologic structures, flood plain management, river ecological studies and flood insurance studies. The national guideline for design flood estimation in Australia known as Australian Rainfall and Runoff (ARR) recommends the Design Event Approach as the preferred method of rainfallbased design flood estimation ...

The real time flood forecasting is one of the most effective nonstructural measures for flood management. For formulating the flood forecast in the real time, the observed meteorological and flow data are transmitted to the forecasting station through the different means of data communication which include telephone, wireless and network of telemetry stations etc. The collected meteorological a...

Abstract The paper considers the problem of inverse flood routing in reservoir operation strategy. aim work is to investigate possibility determining hydrograph at upstream end based on required downstream using simplified open channel flow models. To accomplish this, linear kinematic wave equation, diffusive equation and Muskingum are considered. achieve end, an solution afore mentioned equati...

Most current flow routing algorithms use digital elevation models (DEMs) to construct flow models. In order to successfully use current techniques for flow routing, they flood local minima and then find a way of routing the flow across the flat surfaces. In this paper, we examine an alternative method for computing flow routing on these flooded surfaces that takes into account the original elev...
