In-depth studies in river hydrology, fluvial geomorphology, transboundary water treaties, and cartographic analysis.
Forming the border between the DRC, the Republic of the Congo, and the CAR for 1,410 miles, the Ubangi is the largest right-bank tributary of the Congo River system.
Flowing 250 miles as the sole drainage outlet of the East African Rift's Lake Malawi, the Shire plunges through Kapichira Falls before merging with the lower Zambezi River.
Flowing 264 miles across the North Island of New Zealand, the Waikato drains Lake Taupo's volcanic caldera, coursing through the crashing cyan waters of Huka Falls.
Stretching 1,702 miles through arid outback Queensland and New South Wales, the Darling experiences boom-and-bust hydrology with long dry spells and sudden inland floods.
Flowing 700 miles through tropical cloud forests and vast oxbow lagoons, the undammed Sepik supports rich tribal cultures and one of Earth's most intact river basins.
With an astounding discharge of 6,000 m³/s for a length of just 650 miles, the Fly River discharges immense tropical rainfall into the Gulf of Papua through a 33-mile-wide funnel estuary.
How helical flow and centrifugal shear stress drive cut-bank erosion, point-bar sediment accretion, neck cutoffs, and the genesis of horseshoe oxbow lakes.
Analyzing Leopold and Wolman's classic fluvial threshold: why steep valley slopes, coarse non-cohesive gravels, and variable discharge create multi-channel braided rivers.
When confined mountain canyons emerge onto flat piedmont valley floors, rapid loss of hydraulic depth triggers fan-shaped sedimentary deposits and critical groundwater aquifers.
