Hydroinformatics Blog - A Case for Open Source-based Digital Water Systems

May 10, 2023

Digital transformation stands to transform the operation and design of urban water networks. However, fundamental socio-technical knowledge gaps must be answered before these systems become commonplace. In this post, I make a case that open-source philosophy can help address some of these challenges and create accessible and equitable digital water technologies.

Hydroinformatics Blog - Monitor My Watershed Helps Lower Barriers for Real-time Data Sharing

Jan 10, 2023

The Monitor My Watershed Data Sharing Portal evolved from work by the CUAHSI community for managing environmental data with the Observations Data Model. Monitor My Watershed accepts real-time sensor data and other observation types and provides data visualization and connection with CUAHSI’s HIS. Adoption and use of Monitor My Watershed is growing rapidly partly due to the extensive training resources for DIY hardware

Hydroinformatics Blog - Arc Hydro’s WIM: A Machine Learning Framework for Wetland Identification

Dec 7, 2022

Arc Hydro’s Wetland Identification Model (WIM) is an automated framework for identifying wetlands using machine learning. Its baseline functionality infers wetland likelihood from geomorphologic indicators, but WIM can be configured and extended for your use case. WIM continues to be developed and improved as we gather feedback from users and collaborators in the wetland science community. Our goal is to build a tool that helps that community achieve its goal of better, faster, cheaper wetland mapping.

Hydroinformatics Blog - Advancing Technology for Understanding Residential Water Use

Nov 9, 2022

Collecting, managing and analyzing high temporal (sub-minute) resolution residential water use data is challenging due to lack of existing tools, yet doing so enables better understanding of water use behavior that can help improve urban water management and planning by allowing direct identification of water appliances characteristics. This month's entry to the Hydroinformatics Blog presents low-cost, open-source tools designed to facilitate collection and analysis of this type of data.
