Hydrologic Simulation With a Distributed Hydrologic Model
2008 Fourth International Conference on Natural Computation, 2008Hydrologic processes are sensitive to the spatial distribution of hydrologic parameters in watersheds. A distributed hydrologic model which can simulate various components of a watershed hydrologic cycle such as surface water, channel water, soil water and groundwater as well their interactions is used to simulate various hydrologic processes in the ...

Parallelisation of a distributed hydrologic model
International Journal of Computer Applications in Technology, 2005In the solution of streamflow problems, fully distributed hydrologic models (DHMs), which are based directly on governing equations, offer distinct advantages over conceptual rainfall-runoff models, which are derived from empirical observations. However, the primary problem associated with DHMs is that they consume more computational resources than ...

Applications of GIS and RS in distributed hydrological models
2013 21st International Conference on Geoinformatics, 2013The integration of hydrological models, GIS and RS are the inevitable trend of future development of hydrological models. This paper summarized the research progress of hydrological models, analyzed the applications and development of GIS and RS in hydrological models, pointed out the problems and settlement, and then proposed the future development ...

Modelling the hydrology of a catchment using a distributed and a semi‐distributed model
Hydrological Processes, 2005AbstractVarious hydrological models exist that describe the phases in the hydrologic cycle either in an empirical, semi‐mechanistic or fully mechanistic way. The way and level of detail for the different processes of the hydrologic cycle that needs to be described depends on the objective, the application and the availability of data. In this study the

Simple Snowdrift Model for Distributed Hydrological Modeling
Journal of Hydrologic Engineering, 2004A simple snowdrift model was developed, incorporated into a distributed winter-time hydrological model, and tested against snow measurements from a hillside in eastern Washington State. Snow movement can be an important factor in the distribution of spring soil moisture and runoff.

A Distributed Hydrological Model of Flash-Floods
2001The flash-floods of small watersheds are characterized by a low predictability. The monitoring of these events is in fact very often problematic, due to the size of the phenomenon and to the lack or failure of appropriate real-time survey networks.

Critical Transitions in Water and Environmental Resources
Management, 2004
Accurate predictions of rainfall-runoff relationship have been the goal of numerous hydrologic studies. Despite the availability of data, the usefulness of physically based, distributed parameter hydrologic models over lumped models remains uncertain. The purpose of this study is to evaluate the performance of a physically based, distributed model and ...

A Discussion of Distributed Hydrological Modelling
1990Inspired by the rapidly increasing power of computers and the development of geographical information systems and digital terrain maps, distributed models in hydrology (and other areas such as ecology) have been developing rapidly since the first outline of a physics-based distributed model published by Freeze and Harlan in 1969. Coupled to the opening
