👉 River math, also known as river network analysis or stream network analysis, is a set of techniques used to study and model the structure and dynamics of river systems. It involves analyzing the network of streams, rivers, and tributaries to understand how water flows through a landscape, identifying key features such as main channels, smaller streams, and confluences. This analysis helps in assessing water quality, predicting flood risks, managing water resources, and planning land use. Key metrics include stream order, which ranks streams based on their position in the network, and flow accumulation, which measures the total amount of water flowing through a segment of the river. River math often employs graph theory and spatial analysis to model these networks, providing insights into the hydrological processes and ecological health of river systems.
