The study investigates how low-cost technology can be applied in data-scarce catchments to improve water resource management. More specifically, we investigate how drone technology can be combined with low-cost real-time kinematic positioning (RTK) global navigation satellite system (GNSS) equipment and subsequently applied to a 3D hydraulic model so as to generate more physically based rating curves.

The study was conducted along the Luangwa River in Zambia. It combines low-cost instruments such as UAVs and GPS kits to collect data for the purposes of water management. A novel technique which seamlessly merges the dry and wet bathymetry before application in a hydraulic model was applied. Successful implementation resulted in water authorities with small budgets being able to monitor flows safely and efficiently without significant compromise on accuracy.

We evaluate the influence of elevation and distance from large-scale open water bodies on bias for CMORPH satellite rainfall in the Zambezi basin. Effects of distance > 10 km from water bodies are minimal, whereas the effects at shorter distances are indicated but are not conclusive for lack of rain gauges. Taylor diagrams show station elevation influencing CMORPH performance. The
spatio-temporaland newly developed
elevation zonebias schemes proved more effective in removing CMORPH bias.

This study determines the actual causes of water shortage at Mushandike Irrigation Scheme in Zimbabwe. The water stress at the scheme has been largely attributed to climate change and the uncontrolled expansion of the land under irrigation. Results show that water shortages at the scheme are a result of over-abstraction from the dam beyond the firm yield, adoption of inefficient irrigation methods and high channel losses in the canal system and are not related to hydro-climatic conditions.

Short summary
This paper is about evaluation of sub daily satellite rainfall estimates through flash flood modelling. The 30 minute timestep for CMORPH captures flash floods effectively and for TRMM the 3 hr timestep was the best. In general CMORPH performed better than TRMM in termsof NSE and RVE when applied to HEC-HMS model. It can be concluded that floods occur rapidly and the chances of capturing them are higher when finer resolution are applied.
