Research
As an engineering hydrologist, Bras' major areas of interest include land-atmosphere interactions and geomorphology.
With the goal of "coherent understanding of the global water cycle",
Bras and
Peter S. Eagleson at MIT led scientists to rethink the role of water as an essential component of Earth systems. Bras' books ''Random functions and hydrology'' (1985) and ''Hydrology : an introduction to hydrologic science'' (1990) are considered foundational publications in
hydrologic sciences
Hydrology () is the scientific study of the movement, distribution, and management of water on Earth and other planets, including the water cycle, water resources, and environmental watershed sustainability. A practitioner of hydrology is call ...
, combining traditional land hydrology with atmospheric science, ecology, geology, and geomorphology.
Bras has integrated probability and statistics into hydrology to improve forecasting and risk estimation. By examining the interactions of precipitation, runoff, and soil moisture, he has improved river-flow forecasting and flood estimation.
Remote sensing, satellite data, and information technology can now be used to support distributed hydrologic modeling and the global mapping of water in near to real time.
Bras has developed models of the structure and evolution of river basins in terms of their fractal organization and geometry. His work enables researchers to better understand erosional development on hillslopes and channels within catchments. Mass transport processes modelled include fluvial sedimentation, creep, rainsplash and landslides.
In his work in
ecohydrology
Ecohydrology (from Greek , ''oikos'', "house(hold)"; , ''hydōr'', "water"; and , '' -logia'') is an interdisciplinary scientific field studying the interactions between water and ecological systems. It is considered a sub discipline of hydrology, ...
, Bras tries to integrate information about the hydrosphere, atmosphere and biosphere. He seeks to quantify the ways in which plants affect and are affected by hydrologic and energy cycles in the environment.
With
Elfatih Eltahir he examined the role of precipitation recycling on the atmospheric branch of the water cycle of the Amazon River basin, and showed that deforestation can have serious impacts on climate. Bras is considered a leading authority on soil-vegetation-atmosphere system modelling and the evolution of landscapes due to climatic disturbances including
global warming
In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to E ...
