ERN-NHRain

The modeling of rainfall not associated with the passing of a hurricane nearby a specific region can be performed using ERN-LluviaNH, developed by ERN-AL.

This software allows the generation of elliptical stochastic storms that are obtained from PADF (Precipitation, area, duration, frequency) curves for a goven basin.

Here you can download the software installer and make comments on your use experience.

Training on Multi-Hazard risk assessment

As part of the capacity-building activities of the United Nations University – ITC Center on Spatial Analysis for Disaster Risk Management (UNU-ITC DRM) the Faculty of Geo-information Science and Earth Observation (ITC) of the University of Twente, the Netherlands, has developed a training package on the application of GIS for multi-hazard risk assessment.

Upstream Regulation Adjustments to Ensemble Streamflow Predictions

The work reported herein addresses the problem of adjusting Ensemble Streamflow Predictions (ESP) to account fot upstream regulation effects to downstream flows in real time. The solution methodology includes the use of regression relationships to eliminate bias in the ESP predictions, among other means.

Predicting Morphological Changes in Rivers, Estuaries and Coasts

Flooding occurs when there is a functional or structural failure of a defence. The first, arise from society’s need to find a compromise between the cost of the defence and the consequences of a flood. Structural failures are generally more dangerous, as they are unexpected and source of notable flooding.

Disaster Management and Flood Hazard Mapping

The goal of the flood management is to minimize the damage of life and property and to maximize the benefit from floods. Since the flood is a natural phenomenon that usually triggered by severe rainfall, it is difficult to get full control over it.

Flood Inundation Modelling

Inundation modelling is essential for flood event management. Plans for warning, evacuation and traffic routing often are based on computed flooding patterns, water depths and arrival times of the flood water.
