River & Stream Restoration Services
Agua Tierra Land and Water Services, Inc. has performed reach analysis, channel assessment, and stable channel design on miles of river and stream restoration projects throughout the Northwest. Our interdisciplinary approach systematically begins with assessment and design of fluvial geomorphology, hydrology, and hydraulics. Agua Tierra then integrates habitat components and intensive use of native vegetation into our designs. A hallmark of Agua Tierra㠤esign approach is our use of reference reach conditions, channel geometry studies, and analysis of sediment transport.
Areas of expertise include:
Hydrology / Fluvial Geomorphology
River Restoration & Natural Channel Design
Fish Habitat Restoration & Enhancement
Reach Analysis & Meander Belt Studies
Flood Hazard Management & Floodplain Restoration
Bioengineering / Bank Stabilization
Regulatory Coordination & Public Involvement
Construction Inspection & Monitoring
