Runoff forecasting in mountainous regions with processed based models is often difficult and inaccurate due to the complexity of the rainfall-runoff relationships and difficulties involved in obtaining the required data. Machine learning models offer an alternative for runoff forecasting in these regions. This paper explores and compares two machine learning methods, support vector regression (...

Design of water infrastructures requires estimation of design flow which is the runoff that an infrastructure can handle safely. For estimation of this design flow, rainfallrunoff modelling is widely adopted. Temporal pattern (the distribution of rainfall depths over sub-storm durations) is considered to be one of the most critical input variables in the rainfall-runoff modelling. Design tempor...

A connection between El Nino Southern Oscillation (ENSO) and weather phenomena in eastern Australia has been recognized for several decades. However, little work has been devoted to addressing how this correlation affects hydrological system behaviour within regional-scale catchments. In this study, spatially distributed ENSO effects are evaluated in terms of monthly rainfall, evaporation, stre...

Rainfall-runoff models sometimes have to deal with hydrological systems for which the water balance cannot be closed without taking into account the relation between surface and groundwater. In this study we intend to clarify in which kind of situations surface hydrologists should worry about these relations. We also conduct a preliminary study about how underground exchanges could be integrate...

Rainfall runoff modeling is one of the most complex hydrological due to involvement different watershed physical parameters. It essential for analysis response towards received precipitation under influence variables. As it a replica response, Rainfall-Runoff evaluate general characteristics total surface at catchment’s outlet. The main objective this study was prediction rainfall using Hydrolo...

Phosphorus losses from agricultural land can cause accelerated eutrophication of surface water bodies. This study evaluated the use of soil test phosphorus (STP) levels to predict dissolved inorganic phosphorus (DIP) concentrations in runoff water from agricultural soils using laboratory rainfall simulation. The objectives of this study were to determine (i) to what extent STP concentrations ca...

During tropical storms, precipitation and associated rainfall-runoff can lead to significant flooding, in both the upland coastal areas. Flooding areas is compounded by storm surge. Several hurricanes recent history have exhibited destructive force of compound flooding due precipitation, rainfall-runoff, surge waves. In previous work, various coupled modeling systems been developed model total ...
