Operational prediction of flash floods produced by thunder storm (convective) precipitation in mountainous areas requires accurate estimates or predictions of the precipitation distribution in space and time. The Details of the spatial distribut[...]

Storm frequencies for the future are often estimated directy from past historical records of sufficient length. The Estimation requires no detailed knowledge of the area's meteorology, but presumes it is unchanged in the future. However, the cli[...]

The Estimation of extreme quantiles corresponding to small probabilities of exceedence is commonly required in the risk analysis of flood protection structures. The Usefulness of L-moments has been well recognized in the statistical analysis of [...]

The Skew coefficient is an important statistic in flood estimation at gaged sites, but sample values are subject to considerable sampling variation, and the map skew lacks both a conceptual basis and acceptable accuracy. While weighting the samp[...]

A Daily rainfall disaggregation method, yielding regional hourly rainfall estimates, is presented with application to continuous-simulation watershed models. The Disaggregation method estimates the number and volume of rain events each day and s[...]

In the Himalayan region of India, most prospective sites microhydro projects are ungauged and there are insignificant data for analysis. Design flow estimates are made using a regional flow-duration curve. Regional studies on Himalayan watershed[...]

A Continuous simulation storm water management model (with 33 years of historical precipitation) was used to determine how the design criteria from five different storm water management pond ordinances changed the runoff from a 7.77 has watershe[...]

The Conventional hydrological model QualHYMO, which uses infiltration excess overland flow as the primary mechanism for runoff generation, is compared with a variable source area that was modified for use on urbanizing watersheds. The Modified v[...]

An explicit solution of the Green and Ampt infiltration equation is presented by constructing a decomposition series. Simple expressions for the cumulative infiltration depth and the infiltration rate are proposed. These expressions are valid fo[...]

In this study is shown that in heterogeneous porous media all the ensemble average conservation equations, representing linear reactive and non reactive transport at a spatial scale one step larger than the Darcy scale, are in the same operator [...]

In this study, the rational method is expanded into the rational hydrograph method in which the time of concentration is considered as the system memory and the contributing rainfall depth to the present runoff rate is defined as the accumulated[...]
