Field to stream: analyzing the network timescale of sediment transport and legacy phosphorus mobilization

Institute: Minnesota
USGS Grant Number:
Year Established: 2022 Start Date: 2022-12-01 End Date: 2025-11-30
Total Federal Funds: $221,897 Total Non-Federal Funds: $221,897

Principal Investigators: Diana Karwan

Project Summary: Degraded surface water quality, including harmful algal blooms and associated "dead zones", is a frequent outcome in regions with intensive agricultural land use. The movement of nutrient-rich water and sediments from the land to nearby streams and rivers is facilitated by processes such as erosion and artificial drainage.
