As instream flow specialists, we are familiar with one-dimensional (1-D) methods used in instream flow studies including wetted perimeter and R-2 Cross. We specialize in IFIM studies and maintain the most current versions of the PHABSIM (data analysis component of IFIM) software. We have conducted complex analysis on multi-river networks to develop instream flow recommendations for water use and project impact assessment using 1-D and 2-D modeling techniques.
• Instream Flow Recommendations
• 2-D Hydraulic Modeling
• 1-D Surveys (PHABSIM, R2-Cross, wetted perimeter)
• Evaluate Impacts of Multiple Management Alternatives
• Habitat Use Quantification
• Habitat Suitability Criteria Development
• Habitat Quantification
• Minimum Flow Analysis
• Stream Network Habitat Analysis
• Data Review and Analysis
• Stream Temperature Modeling
Recently, two-dimensional (2-D) hydraulic modeling techniques have become the standard tool to evaluate instream flow issues. Miller Ecological Consultants, Inc. is a leader in 2-D hydraulic modeling and we have designed and conducted 2-D studies on western river systems ranging from 3 to 50,000 cfs. In addition, we have developed software that allows seamless integration of 2-D hydraulic modeling outputs with a GIS framework. This innovative technique produces a visual representation of data which can simplify the decision making process.
We have designed and conducted studies to develop habitat suitability criteria for both cold-water and warm-water species. We have extensive experience in study design for habitat suitability studies including appropriate field data collection techniques and univariate and bivariate data analysis procedures. In addition, we have designed studies for habitat assessments which included habitat suitability and habitat mapping.
We can design and conduct 1-D and 2-D instream flow studies for all sizes of river systems. We have extensive experience in large river systems and are capable of data collection in most water conditions. We are proficient in the use of standard survey equipment (total station) as well as high-tech survey grade GPS methodologies to collect necessary hydrologic field data.
With our extensive background in instream flow studies, we also provide project oversight and review services as a quality control measure for existing or on-going instream flow studies. We also provide expert review of instream flow studies in litigation cases
