Hydrology, Environmental Engineering - Hydrology & Hydraulic Modeling, Groundwater Modeling & Analysis, Stormwater Management, Regulatory Compliance, Environmental Studies, Water Quality, Groundwater Sustainability Plans, Mixing Zone Analysis & Dilution Credit, Aquifer Storage & Recovery, Environmental Permitting

Masih Bari, PhD, PE brings two decades of experience in water resources planning and management, hydrology, and environmental permitting, with a practice focused on defensible technical opinions in regulatory and litigation matters. Dr. Bari’s work centers on hydrologic and hydraulic modeling and analysis, groundwater modeling and evaluation, mixing-zone and dilution analysis, stormwater and watershed planning, and water-quality modeling and compliance. His project portfolio includes groundwater sustainability planning under California’s Sustainable Groundwater Management Act (SGMA), discharge and dewatering permit strategy, and basin-level planning and model development in support of permitting and infrastructure decisions. He has performed hydrologic simulations, watershed-scale evaluations, mixing-zone and dilution studies for municipal agencies and utilities across California and the United States. Dr. Bari has direct expert-witness experience, including independent model revi...

Ms. Abadie is a Civil Engineer with a background in hydrology and water resources. She provides root cause and scope of damage evaluations and expert witness services. Prior to joining EDT, Ms. Abadie worked in multiple sectors of water and wastewater: groundwater protection, drinking water treatment and distribution, wastewater collection and treatment, urban runoff control, watershed assessment, and asset management. She spent twelve years as a collection system engineer for the City and County of San Francisco where she developed San Francisco’s Combined Sewer Discharge inspection program, installed dozens of flowmeters, walked and crawled through hundreds of miles of sewers, designed two baffles, ran model simulations, investigated flooding claims, oversaw repairs of large underground concrete structures, and pulled a bicycle out of a pump station inlet.

Dr. Abdelhamid has been designated as an expert witness for many litigated cases. Dr. Abdelhamid is heavily involved in performing forensic geotechnical and geophysical investigations for several problematic foundations, pavements, retaining walls and slopes. He devises protocols for geotechnical and geophysical testing, in-situ long-term monitoring, lab testing and analysis. He is also heavily involved in preparing and reviewing proposals and expert reports for geotechnical exploration and litigated and non-litigated forensic projects. Dr. Abdelhamid is responsible for meeting clients during the proposal phase, the investigation phase and after releasing the final report to ensure client satisfaction. Dr. Abdelhamid has performed work at wide variety of forensic projects. He evaluated numerous residential buildings from single family house to a whole subdivision. Dr. Abdelhamid also evaluated many commercial, school, hospital, garage buildings. He performed stability analysis for v...
