A Two-layer soil water balance model is developed to provide an efficient and robust description of land surface dynamics in response to atmospheric evaporative events. Soil, vegetation, and atmosphere are coupled dynamically under the assumptio[...]

This Study investigated the use of similarity profiles in space for analyzing surface-runoff hydrographs occuring at the outlet of small watersheds. The Spatial behavior of the flow depth over each element (overland region or stream reach) was a[...]

Mean areal precipitation values (MAPX) derived from next generation weather radar (NEXRAD) stage III data are compared with mean areal precipitation (MAP) values derived from a precipitation gauge network. The Gauge-derived MAPXs utilize the gri[...]

In hydrocarbon-contaminated sites, it is common practice to estimate the total hydrocarbon volume based on the hydrocarbon thickness measurements made in monitoring wells. In most cases, the hydrocarbon thickness measurement data obtained from a[...]

The Usefulness of a hydrologic model depends on how well the model is calibrated. Therefore, the calibration procedure must be conducted carefully to maximize the reliability of the model. In general, manual procedures for calibration can be ext[...]

Hydrologists and water resource planners in the pacific Northwest region of the United States are under pressure from competing water users to make long-range forecasts of stream flow. At present, long-range stream flow forcasts are not offered.[...]

The Writers have formulated quasi-analytical nonlinear solutions to investigate the uncertainty of one-dimensional ground-water flow in heterogeneous formations in which the standard deviation of log hydraulic conductivity σ1n(k)> 1. The Writer[...]

This Paper describes the development of simplified momentum equations, in stage as well as in discharge formulations, governing the transition between the diffusion and the kinematic waves (including the latter). It also describes the applicatio[...]

A Hydrologic model, capable of approximating surface and subsurface runoff from a forested shallow-soil watershed without the time of concentration parameter, is developed. A Watershed is modeled as a series of vertically and horizontally linked[...]

Gridded precipitation products created as part of the U.S. National Weather Service's Next Generation Weather Radar (NEXRAD) program are referenced to a national grid called the Hydrologic Rainfall Analysis Project (HRAP) grid, which is used to [...]

In level pool rooting, which the simplest hydrological routing method, the downstream discharge may be expressed explicitly in terms of the inflow and the channel or reservoir characteristics. The Level pool routing equation can also be used to [...]
