About this opportunity
Here is a two-paragraph summary of the key details of this Federal Grant Opportunity:
The US Army Corps of Engineers (USACE) Engineer Research and Development Center (ERDC) is seeking proposals for the development and application of hybrid numerical-machine learning models to predict harmful algal blooms (HABs) in inland reservoirs and lakes. The overarching goal is to create an improved hybrid modeling system that combines watershed, hydrodynamic, and machine learning models to provide accurate HAB predictions at high spatial and temporal resolution. The project aims to: 1) Improve the spatial and temporal resolution of HAB predictions, 2) Diagnose the specific drivers of HABs in managed reservoirs, and 3) Enable deployment of the hybrid modeling system at additional USACE reservoirs. Proposals will be evaluated on technical merit, feasibility, qualifications of the project team, and alignment with the stated objectives.
The funding opportunity is part of the CFDA 12.630 Basic, Applied, and Advanced Research in Science and Engineering program, with a total estimated funding of $212,770.60 across a 2-year period of performance. The project will likely involve a combination of laboratory research, field studies, and data analysis, with performance taking place at the applicant's facilities as well as specified field locations.
Synopsis
Methods to quantify and predict vulnerability to harmful algal blooms (HABs) has not been developed for most lakes and reservoirs in the U.S. (and the world). This limits the ability for water quality stakeholders to 1) avoid costly emergency events, 2) efficiently design source water monitoring, 3) evaluate the impact of interventions, and 4) maintain trust with the public. Current approaches for detection and prediction of harmful algal blooms rely on infrequent satellite imagery and/or water samples, and provide predictions only at specific sites (i.e., where samples are taken). Furthermore, the models used to make predictions do not typically provide an ability to diagnose the specific drivers of HABs, beyond weather variables. The challenges confronting water quality stakeholders like the USACE are to 1) improve the spatial and temporal resolution of HAB predictions; 2) have the ability to diagnose the causes of HABs in managed reservoirs.
The overarching goal of this project is to develop and test a hybrid modeling system that combines watershed, hydrodynamic and machine learning models to provide accurate predictions of HABs in USACE reservoirs, at high spatial and temporal resolution.
The products that this project will create include:
1) A hybrid modeling system for making accurate predictions of HABs at USACE reservoirs, improving on the state-of-the-art in terms of spatial coverage and temporal frequency;
2) Demonstrated utility of the hybrid modeling system for identifying the drivers of HABs, and for estimating the efficacy of interventions;
Documentation and training to enable deployment of the hybrid modeling system at additional USCAE reservoirs.
