Abstract
Three debris-flow simulation model software have been applied to the back analysis of a typical alpine debris flow that caused significant deposition on an urbanized alluvial fan. Parameters used in the models were at first retrieved from the literature and then adjusted to fit field evidence. In the case where different codes adopted the same parameters, the same input values were used, and comparable outputs were obtained. Results of the constitutive laws used (Bingham rheology, Voellmy fluid rheology and a quadratic rheology formulation which adds collisional and turbulent stresses to the Bingham law) indicate that no single rheological model appears to be valid for all debris flows. The three applied models appear to be capable of reasonable reproduction of debris-flow events, although with different levels of detail. The study shows how different software can be used to predict the debris-flow motion for various purposes from a first screening, to predict the runout distance and deposition of the solid material and to the different behaviour of the mixtures of flows with variation of maximum solid concentration.
May 01, 2009 BOSS DAMBRK offers advanced modeling BOSS International, a developer of civil engineering hydrology and hydraulic software, offers DAMBRK, a one-dimensional hydrodynamic flood routing software. DAMBRK software can model hydrodynamic flood routing, dam failures, storage effects, floodplain overbank flow, and flood wave attenuation. We want to thank you for your use of Dodson Software Products. Roy Dodson began this program to make useful products available to the general engineering community in a format that was friendly and intuitive in a time when electronic design products were first being introduced. He developed software versions of other common tools of the trade to improve the experience of these tools to combat. Abstract and Figures. The national weather service (NWS) FLDWAV and DAMBRK models have been the standard programs and widely applied for dam break flood simulations for years. In the last two. A cost-effective GIS tool for a simplified prediction of the downstream flooding produced by a failure of a concrete dam. The tool is able to provide the essential information for the dam-break analysis: (i) the evaluation of the breach outflow discharge, (ii) the downstream flood propagation, (iii) the map of the downstream flood-prone areas.

- Abstract:
- Dams are constructed to serve a variety of purposes such as supply of drinking and irrigation water, generation of electric power, flood protection etc… However a dam break may result in high flood waves traveling along a valley at quite high speed. The intensity of the catastrophic failure of dams varies depending on the extent of inundated area, size of the population under risk and the warning time available. The present study deals with the Dam Break Analysis of Thenmala Dam of Kerala State, India. As a part of the work, the maximum precipitation and maximum flood have been evaluated using the Gumbel's and Clark's method respectively. The final analysis is done using the software BOSS DAMBRK for evaluating the extent of inundation, travel time and velocity of downstream progressing water.
