Somalia Flood Advisory for Juba and Shabelle Rivers - Issued 20 October 2023

Moderate Risk of Flooding Along Juba River Particularly at Luuq and Bardheere Heavy rains received over Luuq (80.5 mm), and moderate rains (26.2 mm) observed over Dollow on 20th October 2023, coupled with moderate rains across the Ethiopian border have resulted to a sharp rise in river level at Luuq from 3.84 m on 18th to 5.6 m and at Dollow from 4.26 m on 19th to 4.78 m today. Added to previous light rains (14.1 mm) observed on 19th October at Luuq, moderate flood risk levels have been surpassed by 0.22 m and 0.1 m at Dollow and and Luuq, respectively. These localized rains also led to flashfloods affecting IDP camp at Luuq. Moderate rains received over Beletweyne (38.5 mm) on 20th October 2023, and possibly more intense rains over the surrounding areas, coupled with moderate rains across the Ethiopian border have led to a noticeable rise in river level at Beletweyne from 4.95 m on 19th to 5.15 m today (20th October 2023). The rainfall forecast for the next three days indicates moderate to heavy rain (50 – 150 mm) within the Somali-Ethiopia border particularly over upper parts of Gedo region, central parts of Bakool region and many parts of Hiraan region. Although only light rains (4 mm) have been observed at Bardheere today (20th October), the forecast moderate rains in the 24 hours and coming days over upper parts of Gedo region, is likely to lead to further rise in the river levels with moderate risk of flooding along the entire Juba River stretch with the flood wave expected at Bardhere within 2 days. This is therefore an alert to trigger both riverine and flash floods anticipatory actions and to caution communities living along the Juba riverine areas particularly Luuq and Bardheere districts to be vigilant and heed to anticipatory measures as the river levels keep rising. Although the risk of flooding along Shabelle River remains low today, the forecast moderate to heavy rains over Hiraan will lead to increase in river levels. If the heavy rains over Hiraan materialize, it may result in incidences of flash floods today and whose resultant run off and flood wave is expected to flow downstream towards Bulo Burte Burte and Jalalaqsi in the coming days. Additionally, the large volumes of water that was sighted at Limey district in Ethiopia which forms part of the upper catchment of Shabelle river, is likely to lead to a rise in water level at Beletweyne in two to three weeks.

Higher Ground for Flood Evacuation in Bardheere and Luuq Districts

Somalia grapples with the looming impacts of an impending El Niño, exacerbating the ongoing climate change challenges. Recurrent riverine and flash floods, particularly in urban centers are of significant concern. Urgent action is needed to prepare for and mitigate the forthcoming El Niño floods, aiming to safeguard lives and mitigate economic losses. Key to this strategy is proactive flood management, involving timely evacuations to higher ground. Identifying suitable elevated areas serves a dual purpose, ensuring safety and facilitating aid delivery. In this regard a rigorous GIS & RS methodology by SWALIM considered nine crucial factors, such as historical flood extent, elevation, slope, topographic wetness index, drainage density, strategic boreholes, settlements, land cover, and roads, to isolate higher grounds suitable for evacuation. The resulting maps show safe areas for evacuation in case of flooding, while exercising discretion considering factors like proximity to schools, healthcare facilities, pest prevalence and any other unforeseen factors.

Somalia Flood Advisory for Juba and Shabelle Rivers - Issued 21 October 2023

Shabelle River In the last 24 hours, heavy rainfall has been received and recorded (21st October 2023) at Beletweyne (88.2 mm), Mataban (40.0 mm), Bulo Burte (51.0 mm), Mahaday Weyne (20.0 mm), Jalalaqsi (87.0 mm), Jowhar (18.0 mm) and Balcad (23.0 mm). Compared to yesterdays’ measurements, the levels have increased by 1.29 m at Beletweyne, and by 0.12 m at Bulo Burte, while it remained stable at Jowhar. These localized rains also led to flash floods in Beletweyne which affected population, assets, and livestock particularly at the bridge near the ex-livestock market and in Hawo Taako and Kooshin villages. The IDPs are reported to have been safely evacuated to Ceel Jaale. Light rainfall is predicted over the Shabelle catchment within the country in the next 24 hours increasing to moderate cumulative amounts in the coming seven (7) days. Although light rain is forecast over the Shabelle river basin in the Ethiopian highlands today, it is expected to increase to between moderate and heavy rains in the coming seven (7) days. The runoff from previous heavy and forecast light localized rains onto and from seasonal wadis within Hiraan region, together with moderate to heavy rains over the river basin in the Ethiopian highlands, will keep the water levels along Shabelle River rising in the coming seven (7) days. This is therefore an alert to trigger both riverine and flash floods anticipatory actions and to caution communities living at vulnerable areas in Hiraan to be vigilant as the flash flood water stagnates over the saturated surfaces in Beletwyne and the water levels along Shabelle River keep rising. Juba River In the last 24 hours, moderate rainfall has been received and recorded (21st October 2023) at Bardheere (15.0 mm) and Luuq (2.5 mm) with dry conditions over Dollow and Bualle. Compared to yesterdays’ measurements, the levels have increased by 0.5 m at Luuq, increased by 1.04 m at Bardheere, decreased by 0.24 m at Dollow and decreased by 0.17 m at Bualle. The flash floods due to previous localized rains at Luuq have subsided as the water run off to the seasonal wadis and into the Juba River. Light rainfall is predicted over the Juba catchment within the country in the next 24 hours increasing to moderate cumulative amounts in the coming seven (7) days. Although light rain is forecast over the Juba River basin in the Ethiopian highlands today, it is expected to increase to between moderate and heavy rains in the coming seven (7) days. The runoff from previous heavy and forecast light localized rains onto and from seasonal wadis within Gedo region, together with moderate to heavy rains over the river basin in the Ethiopian highlands, will keep the water levels along Juba River rising in the coming seven (7) days. This is therefore an alert to trigger both riverine and flash floods anticipatory actions and to caution communities living at vulnerable areas in Gedo particularly at Luuq and Bardheere to be vigilant as the flash flood water stagnates over the saturated surfaces in Luuq and the water levels along Juba River keep rising.

Somalia Flood Update for Juba and Shabelle Rivers - Issued 23 October 2023

Significant fluctuations in water levels along the Juba River have been observed. The Juba River surpassed the high-risk thresholds by 10 cm at Luuq on 21st October before decreasing below moderate risk level as of today. Downstream at Bardheere Station, the water level rose from 8.00 m on 21st October to 9.00 m and crossing high-risk threshold (8.20 m) on 22nd October before receding back to 8.00 m today. The downstream flow of the flood wave has led to a 1.1 m rise in the water level at Bualle which currently poses no immediate threat of riverine flooding. Moderate to heavy rains (50 – 100 mm) are expected over the catchment of Juba River within Gedo region and near-border areas with Ethiopia between 23rd and 29th October. The rains over the upper catchment in Ethiopian Highlands may exceed 200 mm posing high risk of riverine flooding towards the end of the forecast period. There is a high risk of flash flooding due to potential localized heavy rains over western parts of Bakool, central parts of Gedo, and Saakow district in Middle Juba region. The water levels along the upper part of Shabelle River are on downward trend. On 21st October, the water level at Beletweyne (6.44 m) was only 6 cm below the moderate flood risk threshold. The levels have since dropped to 6.10 m today. The downstream flow of the flood wave has led to an increase in the water level at Bulo Burte from 4.95 m on 21st October to 5.28 m today. The water level at Jowhar station has also risen during the same time from 3.95 m to 4.28 m. These levels, at both stations, are still below riverine flood risk thresholds. Moderate rainfall (31.5 mm) led to flash floods that affected Badda Cas IDP camp interrupting livelihood activities. Moderate rainfall of about 50 mm is expected over Shabelle River catchment within Hiraan region and near-border areas with Ethiopia. Coupled with the heavy rains recorded one week ago, the heavy rains (more than 150 mm) forecast over the Shabelle River upper catchment in Ethiopian Highlands, are likely to pose high risk of riverine flooding at Beletweyne towards the end of October and beginning of November 2023.

Status of River Breakages Along Juba and Shabelle Rivers - Issued October 2023

The Food and Agriculture Organization’s Somalia Water and Land Information Management (FAO SWALIM) Project, has finalized the analysis and mapping of the river breakages along the Juba and Shabelle rivers using very high resolution satellite imagery. Breakages identified in the map have been classified into four different categories; Open, Overflow, Canal Flooding Point and Closed with sandbags. A legend/Key for further explanation of the different types of breakages is provided. A total of 170 Open points, 46 Canal flooding points, 152 Overflow points and 29 points closed with sandbags have been identified along the Shabelle River while 26 Open points, 10 Canal flooding points, 16 Overflow points and 14 points closed with sandbags have been identified along the Juba River which require immediate attention. Several other points, which are either potential or temporarily closed with sandbags, have also been identified. The forecast ElNino season is likely to result to enhanced rainfall in Somalia and Ethiopian Highlands with high potential of flooding over the Juba and Shabelle rivers especially where open and potential points have been identified. There is therefore an immediate need to close the open points and reinforce areas where there are weak river embankments. Intervening agencies are advised to take advantage of the current dry period until the rains start and carry out temporary or long term measures to close the river breakages. This will see a reduction of riverine flooding in case of heavy rains and consequently a massive reduction in economic losses to the country.
