Two of the most relevant components of any flood forecasting system, namely the rainfall-runoff and flood inundation models, increasingly benefit from the availability of spatially distributed Earth Observation data. With the advent of microwave remote sensing instruments and their all weather capabilities, new opportunities have emerged over the past decade for improved hydrologic and hydrauli...

PURPOSE: The purpose of this System-Wide Water Resources (SWWRP) technical note is to describe the application of the Gridded Surface Subsurface Hydrologic Analysis (GSSHA) model at the Goodwin Creek Experimental Watershed (GCEW). The purpose of applying the model at this site was to confirm that the hydrologic portions of the code were working properly and were able to achieve accurate results...

Currently, the river forecasting system deployed in each of 13 River Forecast Centers of the National Weather Service primarily uses lumped parameter models to generate hydrologic simulations. With the deployment of the weather surveillance radar 1988 Doppler radars, more and more precipitation data with high spatial and temporal resolution have become available for hydrologic modeling. Hydrolo...

This paper presents a procedure for standard application of hydrologic ⁄water quality models. To date, most hydrologic ⁄water quality modeling projects and studies have not utilized formal protocols, but rather have employed ad hoc approaches. The procedure proposed is an adaptation and extension of steps identified from relevant literature including guidance provided by the U.S. Environmental ...

Rain garden (RG) has been developed and applied to low-impact designs for the purpose of water quality enhancement. A RG consists of a surface storage basin and subsurface infiltrating layers. The storage basin is designed to be shallow, flat, and wide with an overtopping weir to pass excessive flows, while the subsurface infiltrating system is composed of two layers of filtering media. The upp...

This study investigates basin-scale hydrologic implications of the replacement of forest-dominated land cover by rubber plantations in Montane Mainland Southeast Asia. The paper presents a new method for estimating the water demand of rubber and consequently water losses to the atmosphere through rubber evapotranspiration (ET). In this paper we argue that rubber ET is energy-limited during the ...

Physics-based distributed hydrologic models (DHMs) simulate multiple hydrologic states at numerous locations within a watershed, and at fine time intervals [1-7]. As the spatio-temporal resolution of model simulation becomes finer and number of predicted hydrologic states becomes larger, model simulations become more and more computationally intensive, rendering solution of large problems intra...
