OPIDIN - Forecast tool to predict the inundations in the Inner Niger Delta

Floodviewer and forecast

From August up to and including October OPIDIN predicts the height and timing of the maximum flood in the Inner Niger Delta (FLOOD FORECAST) and gives a map of the flooding of the delta at the peak of the flood (FLOOD VIEWER).

Rainfall

The flooding of the Inner Niger Delta depends on the river flow of the Niger and Bani Rivers, which in turn depend on the rainfall in the Upper Niger Basin. OPIDIN provides regularly updated information on recent rainfall in the Upper Niger Basin and a rainfall forecast, all based on satellite information.

OPIDIN explained

In this section background information is given on OPIDIN. A snapshot of examples of the application of OPIDIN is given, and how it serves as Early Warning System. Next we provide information on how communities in the delta adapted to water management in the past as well as a snapshot of examples of OPIDIN as Early Warning System. This section also contains the technical background of the tool.

Communication

The annual peak and extent of flooding is essential to the communities in the delta. Communication is done via the current website and weekly bulletins. These bulletins are used by radio stations in the Inner Niger Delta, broadcasting in several languages. They inform about the situation of the flood and the prediction for the coming weeks during the period August-November.

Bulletin 19 | 18 November 2024

This is the last OPIDIN bulletin of the flooding season 2024. The flood at Mopti has reached its highest level (716 cm) on 8 November. Such a high flood level has not been measured since more than 50 years. In the southern part of the delta the water level has started to decline, but further downstream the water still goes up.

Oct 16, 2024

Bulletin 8 | 16 October 2024

The flood level in Mopti nearly reached its peak, currently reaching a level which is 22 - 27 cm higher than the peak floods in three recent years with very high flood levels (2018, 2020 and 2022). OPIDIN predicts that the flood of 2024 will be very high, much higher than the peak floods of the last 50 years.

Oct 03, 2024

Bulletin 7: 3 October 2024

OPIDIN predicts that the flood of 2024 will be extremely high, comparable to the highest floods measured over the last 75 years. On October 2, the water level had already reached 683 cm, 20 to 40 cm higher on this date than in the last three years of very high floods. A further increase will be limited.

About

Objectives

OPIDIN (Outil de Prédiction des Inondations dans la Delta Intérieur du Niger) is a tool developed for the Inner Niger Delta to predict the level and the timing of the flood peak as well as the maximal flood extent

Approach

The seasonal flooding of the Inner Niger Delta is the lifeline for communities and biodiversity in this flood-dependent ecosystem and economy. Fishermen, rice farmers and pastoralists time their (socio-)economic activities to the flooding pattern in time and space. That has been the main motivation to develop a practical tool to predict the flooding in the Inner Niger Delta

Partners

OPIDIN has been developed through close cooperation between the Direction Nationale de l'Hydraulique, Wetlands International Mali and Altenburg & Wymenga ecological consultants, with the support of the Dutch embassy in Mali.
