Webinar Details

Is your state or region wrestling with the development of a water budget or water accounting?

The California Department of Water Resources has developed a Draft Handbook for Water Budget Development: With or Without Models that provides guidance on water budgeting that is applicable to any state or region. Water budgets provide a means for evaluating the availability and sustainability of a water supply by tracking the movement of water into and out of a watershed. The Water Budget Handbook defines the components of a water budget, documents multiple methods for water budget accounting (with and without models), and identifies necessary considerations for water budget development. It also contains real-world examples and calculations with case-studies from California.

In this webinar, Water Budget Handbook authors Abdul Khan, Todd Hillaire, and Paul Shipman will present an overview of the Water Budget Handbook, answer questions about water budgeting, and solicit feedback. To improve the draft version, the authors would like to hear from you about: (1) the challenges are you facing, (2) which water budget components are important for your state/region, and (3) what kind of tools or guidance would help you with water budgeting/accounting?


Join the Internet of Water and the CA Department of Water Resources for this webinar to: 

  • Learn about the Water Budget Handbook and how to develop or improve water budgets;
  • Ask the authors your questions about water budgeting
  • Share your feedback to improve the Draft Water Budget Handbook and its relevance to your needs and context

Khan Headshot

Abdul Khan, PhD., P.E.

Dr. Abdul Khan has over 30 years of experience in leading and directing teams in water resources planning and management. Since 1992, he has been working in California and have conducted numerous planning, operations, and modeling studies that involved SWP/CVP operations, flood studies, analysis and modeling of groundwater flow and contaminant transport, reservoir operations, temperature and fisheries, and salinity intrusion.   He led the development of the Sustainability Indicators Framework for Water Plan Update 2013. In the development of California’s Groundwater, Update 2013, he played a leadership role by coordinating the technical work of DWR staff and managed a 60-person external Groundwater Caucus. He has been moderating the California Water Plan session for California Water and Environmental Modeling Forum’s annual meeting for the past several years. He manages the Water Budget & Analytics Section in DWR and is leading technical staff for developing the Water Budget Handbook and the Water Budget Dashboard.

He has a Ph.D. from the University of Kentucky, an M.S. from Clarkson University, and a B.S. from Bangladesh University of Engineering & Technology, all in civil engineering. He is a registered professional engineer in California.

Hillaire Headshot

Todd Hillaire

Todd Hillaire has a Bachelor of Science in Civil Engineering from California State University, Chico and is a Senior Water Resources Engineer with the California Department of Water Resources’ Northern Region Office. With over 30 years at CDWR, his experience includes stream gaging, California Water Plan Update, California’s Groundwater (Bulletin 118), land use and water supply infrastructure mapping, water transfers, water resource investigations, stream and meadow restoration, floodplain mapping, flood control project analysis, and channel rehabilitation projects. Work on the California Water Plan Update and water resource investigations involved implementing water budget and water use methodologies and developing crop water use models. Todd has been a subject matter expert for the development of hydrologic/operation models including California Water Resources Simulation Model (CalSIM 3) and California Central Valley Simulation Model (C2VSim). This experience is part of Todd’s integral contribution to the development of the Water Budget Handbook, and he remains committed to the improvement of water budget processes, tools, data sharing, and communication to better understand water management.

Shipman Headshot

Paul Shipman, P.E.

Paul Shipman graduated with high honors from CSU Sacramento with a B.S. in Civil Engineering in 2012. Since then he has worked for the Department of Water Resources as a Water Resources Engineer, currently with the Division of Planning. Paul has worked on a variety of water management and planning related tasks including: the Strategic Plan for Integrated Regional Water Management, Standards for Geothermal Heat Exchange Wells, the Central Valley Flood Protection Plan, the California Water Plan (Bulletin 160), implementation of the Sustainable Groundwater Management Act, California’s Groundwater Report (Bulletin 118), and Implementation of the Open and Transparent Water Data Act. Most recently, Paul has been an integral part of the development of the Water Budget Handbook, the Water Budget Dashboards, and associated pilot projects. He has also been a subject matter expert for the update of various models including the updated California Central Valley Simulation Model or C2VSim. Paul is passionate about serving the people of California by improving the methodologies and documentation behind our technical analyses to support more productive conversations and solutions to real water management problems.
