Mediumand long-term runoff forecasting is essential for hydropower generation and water resources coordinated regulation in the Yellow River headwaters region. Climate change has a great impact on runoff within basins, and incorporating different climate information into runoff forecasting can assist in creating longer lead-times in planning periods. In this paper, a multimodel approach was dev...

several empirical methods for flood flow rate estimation have been presented. in this study,eight new empirical runoff estimation method including dredge & burge, bourges, inglis, faning, hyderabad, burkli ziegler, cramar and possenti were calculated in bakhtegan watershed which is located in fars province. after studying empirical methods for annual flood flow rate estimation and comparing...

The estimation of the amounts Surface runoff resulting from rainfall in water basins is great importance resources management. study area (Bahr Al-Najaf) located on western edge plateau and southwestern part city center Najaf, with an 2729.4 (km2). soil assessment tool (SWAT) ArcGIS software was used to simulate coming three main valleys (Kharr (A B)), Shoaib Al-Rahimawi, Maleh), that contribut...

A new method of calibration of the Australian Water Balance Model (AWBM) daily rainfall-runoff model allows for errors in the estimation of areal rainfall over the catchment. The result of applying the method to a group of gauged catchments is the production of a single set of parameter values for the AWBM that can be used with any catchment in the group, or used to estimate runoff on ungauged ...

This paper investigates the influence of mean areal rainfall estimation errors on a specific case study: the use of lumped conceptual rainfall-runoff models to simulate the flood hydrographs of three small to medium-sized catchments of the upper Loire river. This area (3200 km2) is densely covered by an operational network of stream and rain gauges. It is frequently exposed to flash floods and ...

A parameter estimation method for stochastic rainfall-runoff models is presented. The model considered in the paper is a conceptual stochastic model, formulated in continuous-discrete state space form. The model is small and a fully automatic optimization is, therefore, possible for estimating all the parameters, including the noise terms. The parameter estimation method is a maximum likelihood...

The Spreadsheet Tool for the Estimation of Pollutant Load (STEPL) can be used for Total Maximum Daily Load (TMDL) processes, since the model is capable of simulating the impacts of various best management practices (BMPs) and low impact development (LID) practices. The model computes average annual direct runoff using the Soil Conservation Service Curve Number (SCS-CN) method with average rainf...
