Flow Ruaha at Mtera
Status Flow Mtera June 2, 2023 Status Flow Mtera May 18, 2023 The Ruaha River just upstream of the confluence with the Little Ruaha is still swollen without signs of the upcoming dry season and drying of the river at the selected section of the Great Ruaha which dries first every year.
Early Irrigation Ruaha
The “Natural Color” image of the Kapunga – Ifushiro Area on May 31, 2023 is monitored for Out-Of-Season, early irrigation of rice. Dark fields which could indicate inundated rice fields without crop (pre-irrigation of rice) are analysed using different wavelength band combinations. The yellow arrows are most probably fields with pre-irrigation or leaking/unattended canals. TheContinue reading “Early Irrigation Ruaha”

Zero Flow 2020 The Zero Flow event dates are listed for the Ruaha River Sections next to the magnified remote sensing stations below. The basemap can be viewed here. The related satellite images are grouped per Ruaha River Section with the most recent images on top. The first zero flow event which occurs at theContinue reading “Zero Flow 2020”
Drainage Flow Returns November 12, 2022
Drainage Flow Returns November 12, 2022 Drainage flow on November 12, 2022 After some two months of zero drainage at the Nyaluhanga – Ihefu Swamp section of the Ruaha River drainage flow has returned on November 12, 2022. Compare the two images below, at the same section of the Ruaha approximately 13km (as the birdContinue reading “Drainage Flow Returns November 12, 2022”
End Zero Flow Ruaha predicted January 19, 2023
End Zero Flow Ruaha predicted January 19, 2023 Flow Ruaha River at Mtera confirmed Considering the advance of the surface flow in the Ruaha River on January 18, 2023 (image below) the zero flow period for the river between the source and the Mtera Reservoir will end on January 19, 2023. Advancing surface flow RuahaContinue reading “End Zero Flow Ruaha predicted January 19, 2023”
Increased River Flow abstracted no overflow Ihefu
Increased River Flow abstracted no overflow Ihefu The considerable increase of irrigated area on January 2, 2023 as compared to the December 17, 2022 irrigated area is enabled by the first rains allowing more abstraction from the Mbarali and Ruaha Rivers (green and light blue colors in irrigated area). On the same day as theContinue reading “Increased River Flow abstracted no overflow Ihefu”
Zero Flow Series
Zero Flow Series Ruaha River Mtera Subcatchment38 (Map 1) The approximately 477km long section of the Great Ruaha River from the source to the Mtera Dam (Map 1.) experiences an annual cycle of zero flow events, monitored on this website. For the monitoring and prediction of the zero flow events in the Ruaha National ParkContinue reading “Zero Flow Series”
