Insufficiently gauged basins

Water-related disaster damage has been increasingly worsening in recent years.
One of the most critical factors behind this is that flood forecasting and warning
systems are not properly developed in some countries due to lack of financial
resources and rainfall data. ICHARM has developed IFAS to help such countries
with flood damage reduction. IFAS allows users, even with limited funding and data,
to easily construct an efficient, effective system for flood forecasting and warning.

Rainfall observation by hand

Main features of IFASHouses built along a river

Flow of IFAS application

1. IFAS can use both ground and satellite rainfall data.
2. IFAS can use GIS data available at no cost for model and parameter settings.
3. IFAS can handle everything from data acquisition to runoff simulation to result
display, once installed in a computer with internet access.
4. IFAS can be downloaded free of charge from ICHARM website.

Rainfall data
Satellite-based rainfall
Ground gauged data

Data input

Flow direction generation(Flow direction is determinedat each cell;then, the basin boundary is generated.)

Main display and simulation-result display of IFAS

Global GIS data
Elevation data, Land use data, etc.

Model creation

Runoff analysis(Possible to setdam outflow)

Basin boundary andpseudo river-channel generation

Forecasts and alerts lead safe evacuation.

(The topography of red cells is
automatically corrected
for flow direction generation.)

Output(Exportable toGoogle Earth)

Utilization of IFAS
Utilization of IFAS as a training tool
IFAS training was provided for over 1,000 participantsfrom about 50 countries (2007-2017).
