EXTENDED – The American Institute of Hydrology (AIH) is issuing this Request for Proposals (RFP)

Update: We’ve extended the deadline from April 12 to April 19th! 

The American Institute of Hydrology (AIH) is issuing this Request for Proposals (RFP) to invite entities with specialized hydrology experience in hydrology and qualifications related to development of and training to support hydrology-related examination preparation. Responses are due April 19, 2022.

AIH intends to enter a multi-year contract with a single entity to provide certification exam support services. Note that the single contracted entity may enter into agreements with other entities or individuals to propose on services in responses to the RFP and for performance of services.

The American Institute of Hydrology (AIH) was founded in 1981 as a non-profit scientific and educational organization dedicated to the certification and registration of professionals in all fields of hydrology. AIH is the only nationwide organization that offers certification to qualified hydrologic professionals. AIH’s goal is to promote hydrology as a science and profession and to help protect public interest from non-professional practices.

AIH – The Recertification Process

AIH – The Recertification Process

American Institute of Hydrology certified members provide expert knowledge, specialized skills, and adhere to the highest standards and ethics in the field of hydrology. Recertification of  members assures that they have continued to keep updated with current research, standards and practices. This ongoing educational requirement helps protect public interests and the profession from non-professional, sub-standard or unethical practices in a field involving complex water issues. Because of the continually changing nature of the field of hydrology and societal challenges, certified members need to continue their professional development throughout their careers and keep current in their specialty fields by engaging in professional practice, participating in continuing education courses, keeping up with technical literature, and attending professional meetings and seminars. Professional Development Hour (PDH), or Professional Development Credit (PDC), is defined as one contact hour of instruction, presentation, or study towards the goal of staying current in the field of practice. Specific competency requirements are determined by the Executive Committee on a periodic basis.


Certified members are responsible for keeping records of the number of PDH/PDC they earn along with associated documentation that can be validated by AIH. Documentation is due by January 15 of every 5 years, computed from the anniversary year of the individual member, in order to remain in compliance with certification. A minimum of 60 PDH/PDCs is required over 5 years to be eligible for recertification.

Dates & Deadlines

Certemy has a notification system implemented for those in the recertification phase which notifies those who are approaching their application deadline 3 months ahead of time and again one month ahead. Given the recertification process spans over a 5-year period and requires professionals to provide proof of continuing education over this period of time, we understand that the notification process we currently have in place may not have been an appropriate amount of time to obtain the prerequisites for recertification – specifically the professional development credits component. As a result of this, we have restructured our notification process so that, moving forward, our members will receive notifications beginning 6 months ahead of time rather than 3 months. This will then be followed up by a 3-month notification with an additional final notification 1 month ahead of application due dates. 

AIH is revising the recertification process to make it easier for members to upload their recertification data. Implementation of this process is underway but not yet completed. This will be completed within the next 90 days. With that said, the Executive Committee recently voted on extending the recertification deadline an additional 6 months for any of our AIH professionals that are currently in the recertification phase. It is our hope that this will allow time to obtain the proper material needed to recertify. 

Certified members whose recertification is due in 2022 now have until July 15, 2022 to complete the process. 


Membership Dues

Annual membership dues are required every year, regardless of if you are in a recertification phase or not, in order to continue practicing under your earned credential.


Recertification Fees

Every 5 years, certified members must provide proof of eligibility to recertify, along with recertification fees. These fees are separate from your annual membership dues. 

The points above regarding dates & deadlines, membership dues, and recertification fees are what we hope is captured as a main takeaway from our members reading this message. We greatly value each of our members and we thank you for your continued support of AIH!

President’s Message

AIHPresident Jamil Ibrahim

Greetings! The end of the calendar year is a common period for self-reflection by individuals and organizations. As I look back while concluding the first year of my two-year term as your American Institute of Hydrology (AIH) President, I’m delighted about the accomplishments of your AIH leadership team during 2021. Our achievements this year, however, are not just a function of what we did during 2021 – they consider the steps taken by AIH over the past few years to address challenges and introduce new perspectives, along with the great work of your leadership team.

We did great things in 2021! Thank you to all who contributed. Here’s a snapshot of our accomplishments:

  • Boosted AIH’s membership by 22% compared to 2020 and received 35% more new member applications during 2021 compared to the previous year.
  • Held the Institute’s first virtual meet-and-greet event with AIH members.
  • Connected our AIH community through in-person Water New Year celebrations in Minneapolis, Minnesota and Sacramento, California. One of the three co-founders of AIH, Roman Kanivetsky, joined in the Minneapolis event!
  • Welcomed our first Hydrologic Technician (HT) to serve as a member of AIH’s leadership team on our Executive Committee (EC).
  • Completed a widely popular and informative webinar series on the topic of Forecast Informed Reservoir Operations (FIRO). Our FIRO series, provided in collaboration with the American Water Resources Association (AWRA), featured our nation’s top experts on FIRO, an innovative strategy for water resources management that leverages use of advanced hydrological and meteorological data.
  • Convened a new Diversity, Equity, and Inclusion (DEI) Task Force composed of AIH members and members from the EC. Stay tuned – you will have an opportunity to learn more and support the important activities our DEI Task Force will be initiating within the next few months.
  • Revamped our membership application and database system. Despite the glitches our administration team encountered after the rollout, we’re confident our modernization changes will improve ease of application development by prospective members, application review and processing by our Board of Registration, and provide enhanced member benefits through access of information and content.
  • Presented to audiences at professional conferences about AIH and the importance of Professional Hydrologist (PH) certification for hydrologists and HT certification for hydrologic technicians, including: Groundwater Resources Association of California’s (GRAC) Future of Water Conference; Consortium of Universities for the Advancement of Hydrologic Science’s (CUAHSI) Biennial Colloquium; AWRA’s 2021 Annual conference; and the University of Minnesota’s 2021 Minnesota Water Resources Conference.

AIH President, 2021-2022

Former AIH President Delivers a Keynote Address at the Latin American Congress of Civil Engineering Students

Former AIH President Delivers a Keynote Address at the Latin American Congress of Civil Engineering Students

From November 14-20, 2021, over 120 civil engineering students from nine Latin American countries attended the COLEIC (Latin American Congress of Civil Engineering Students) 2021 event in Tarija, Bolivia.

Dr. Miguel A. Medina, Jr., PH (AIH President, 2009-2010) delivered a keynote presentation on November 17th titled “Water Resources of Bolivia, Integration of Hydrologic Cycle Processes, Climate Change Challenges, Adaptation and Professional Opportunities.” That same day he was invited to the Municipality of Tarija and presented with an ordinance declaring him a Distinguished Visitor. While at the Tarija City Hall, he was interviewed by a local journalist regarding his findings of potential climate change in Tarija.


The following morning a national Bolivian TV (UNITEL) news crew interviewed him live at the Hotel Vendimia lobby on the topic of Bolivian water resources and management, as well as potential climate change implications. The broadcast was also presented again that evening on a national news segment.

On November 18th, Medina also participated in a forum discussion on climate change implications for the civil engineering and hydrology professions.

For his presentation, Medina examined the annual maxima series of precipitation at three recording stations in the region: Tarija (1944-2020), Juntas (11976-2020) and Cañas (1977-2020).

Nonstationary time series analysis with the Generalized Extreme Value Distribution (GEV) was applied to the three stations.

Both Tarija and Juntas exhibited a slight decrease in precipitation. However, at a higher elevation over a mountain ridge, Cañas exhibited a substantial increase in precipitation.

Both deterministic and statistical methods were discussed, as well as surface-subsurface interactions across the hydrologic cycle. The presentation ended with recommendations for infrastructure adaptation to climate change, increased monitoring needs, and a review of current standards. Specific recommendations followed for future training of civil engineers and hydrologists to enhance their professional opportunities.

Book Review by Donald Anderson, PH, Cresta Hydrologics, LLC

By David Owen, Riverhead Books, 2017

The Colorado River is often referred to as “America’s hardest-working river.” As it winds through some of the driest land in the country, it supplies water for more than 40 million people and 5.7 million acres of irrigated lands in seven western states, plus a small slice of Mexico. It eventually dribbles into the dry soils of Baja California, Mexico before reaching its natural historic outlet – the Gulf of California.

The aforementioned population and irrigated acreage values should be considered rather provisional, given the ongoing drought that is diminishing the basin’s water supplies. The Bureau of Reclamation cites a 34% probability that water levels in the massive Lake Powell Reservoir, which stores runoff from the 108,000-square-mile “upper basin” and regulates that water for “lower basin” use, will drop too low to generate hydropower in 2023. This has never happened before Thus, Reclamation implemented emergency measures this year to move 181,000 acre-feet of water down to Lake Powell from its higher-elevation reservoirs in an unprecedented scramble to prop up reservoir storage.

How did America’s hardest-working river come to this sorry state? Where the Water Goes, by David Owen, takes the reader on a journey to understand the convoluted story of how and why the Colorado River can no longer provide what we’ve asked of it in the past.  Consider that  when Owen’s book was published just four years ago, Lake Powell still held 7.4 million more acre-feet of water than today!

Owen’s account is aimed at a broad audience. His writing is light on numbers but heavy on stories illuminating the people, places, and activities associated with the river and its myriad users. He winds his way down the river system in a rental car, from the Colorado headwaters through Utah, Arizona, Nevada and California. We meet families irrigating vineyards in Colorado’s Grand Valley. We meet water managers in Denver and Las Vegas. We meet environmentalists seeking to re-hydrate desiccated wetlands in Mexico’s Colorado River Delta. We tag along with farmers in California’s Imperial Valley growing lettuce for America’s dinner tables, and forage for a global cattle market.

Through these stories, Owen (a staff writer for New Yorker) effectively describes the various hopes, expectations, regulations and stresses that have shaped management of Colorado River flows since the first 14-mile canal was hand-dug in 1890 to move water out of the basin’s headwaters to thirsty agricultural lands on the far side of the Rocky Mountains. His journey is a travelogue as much as a treatise on the Colorado River. This may annoy readers who might prefer more hydrology and fewer human-interest digressions. Nevertheless, through intriguing discourse, Owen skillfully portrays  the convoluted history of the Colorado River – a waterway that has produced, over time, the maddeningly complex body of laws and regulations governing its management.

Importantly, Owen also illustrates how this byzantine body of regulations frequently stands in the way of implementing effective long-term solutions to the problem of over-allocation. As Owen puts it, “If you picked just about any high school civics class in the country and gave its students a year to gather information and think, they could almost certainly come up with an approach to western water use that would be more rational than the arcane patchwork we have currently.”

But, as Owen notes, that’s not going to happen. Instead, those responsible for managing the Colorado will need to collectively determine a path forward through this tangled administrative puzzle by applying creativity, collaboration, and — inevitably — large sums of cash needed to overhaul the status quo.

Owen helpfully reviews various possible paths forward in his final chapter “What is to be Done?” Various proposals — ranging from cloud-seeding to reducing water allocations to importing water from the Great Lakes — are individually examined, highlighting each of their weaknesses. The clear take-home message is that there are no simple solutions. But, also, there is little time to waste. The river is grossly over-allocated, climate change will almost certainly aggravate supply shortages, and managers simply don’t have all the tools they need today to resolve the challenges they’ve inherited.

With Lake Powell now depleted to its lowest level since first filling in the late Sixties, and with the first mandatory water-use cutbacks already impacting water users in Arizona (thereare more to come), we’ve essentially run out of time. Where the Water Goes will help readers retrace the steps that brought us to this eleventh-hour dilemma.
