Recent Projects We Have Accomplished
Listed below are a few representative examples of work Wolf Engineering has successfully completed over the past two years.
|
Rio Grande Restoration Work:
Wolf Engineering successfully completed detailed planning and engineering studies for the Rio Grande from Isleta to San Marcial, NM. We provided oversight, and assistance with the selection and assignment of specific restoration projects and locations in the project reach. We were then responsible for engineering on all selected restoration sites. We produced plans, profiles, and details for each selected site along with preliminary construction specifications and cost estimates. We used Microstation & InRoads to accomplish all layout and drawings.

Jemez River Floodplain Analysis & Design:
This project consists of a hydrologic and hydraulic analysis and mitigation levee design for a four mile reach of the Jemez River through Jemez Pueblo, New Mexico. This was a collaborative project between the Office of Environmental Health and Engineering of the Indian Health Service (IHS) and the Pueblo of Jemez. The goal of the study and analysis is to quantify the potential for and predict the magnitude of flooding along the River and then design a flood water retarding berm to protect a wastewater lagoon. The hydraulics (floodplains) are computed using the U.S. Army Corps of Engineers River Analysis System (HECRAS). Fifteen river cross sections were field surveyed in support of the hydraulic analysis for the project. Additional geometric data, including floodplain cross section data, for the HECRAS modeling was obtained from digital terrain model data using Microstation/InRoads. All plan & profile sheets and civil details for the project were accomplished using Microstation. All geometry for the project was accomplished using InRoads. The results of this study will be used by the IHS and the Pueblo in their planning and design of expanded wastewater treatment facilities for the Pueblo. Flood hazard delineation and potentially, floodplain mediation, prepared in accordance with Federal Emergency Management Agency (FEMA) requirements is required for any new facilities.

Site Drainage Assessment:
We completed a comprehensive site assessment report for the potential development of a 38 acre tract of undeveloped land in Grants, NM. The focus of the study was site drainage. Two arroyos flow near/onto the site. We developed detailed hydrology using a combination of NRCS methodology along with NMDOT procedures to determine peak discharge and volume entering the site for four different frequency events. Wolf developed preliminary plans to safely address flood flow through the property.

PMF Analysis - Ute Reservoir
This project consisted of a hydrologic investigation and drainage study of the Canadian River watershed above Ute Reservoir. The focus is the computation of the probable maximum flood that might be expected to occur in the drainage basin of the Canadian River above Ute Reservoir. The flood event is routed through Ute Reservoir and over the spillway structure to determine, among other things, the maximum water surface elevation. The Canadian River watershed is over 11,000 square miles. We made extensive use of ArcGIS to accomplish this analysis. All computed data was categorized and entered into a project geodatabase.

Rite Way Pallet Grading & Drainage
Project involved calculating off-site and on site runoff for the expansion of a commercial development in the South Valley of Albuquerque. We developed the grading plan and designed detention storage facilities on site to mitigate the additional runoff resulting from developed conditions. In addition, we completed a comprehensive SWPP in compliance with EPA, State of NM, and Bernalillo County regulations for the construction activities.

Bitter Creek Hydrologic Investigation:
As a consultant to a home owner's association we, along with William J. Miller Engineers, completed a site assessment and detailed hydrologic analysis of a small mountainous watershed to determine the probable maximum flood. The probable maximum flood was then routed through two small reservoirs to evaluate their dam safety performance. Work on this project involved the development of an HEC-HMS computer model, review and analysis of model results, consultation with the NM Office of the State Engineer and preparation of a final report.

Hydrographic Survey Support - Chama, NM
Under contract with William J Miller Engineers, assisted with the Hydrographic Survey of over 100 reservoirs located on lands owned by the Jicarilla Apache Nation in Rio Arriba County. This work involved the collection of data on physical characteristics of the dams and reservoirs and the preparation of maps and final report. We used a Leica System 1200 RTK GPS to acquire field data.

Rancho Lobo Pond Capacity Study
Working with William J Miller Engineers, we used Real Time Kinematic (RTK) GPS to capture pond bathymetry of an approximately 20 acre-foot stock pond near Chama, NM. We used a Leica System 1200 survey grade unit to acquire all data, both terrestrial and on the water using a small data collection boat. The final products consisted of a detailed area-capacity table and topographic map of the pond bottom and adjacent shore.

Floodplain Analysis & Flood Routing Study Rio Grande
This project was completed for the U.S. Section of the International Boundary and Water Commission and the Corps of Engineers. We developed and calibrated a FLO-2D model along the Rio Grande from American Dam in El Paso, Texas to Fort Quitman, Texas. The model will be used for predicting overbank flooding and floodwave attenuation and supports the development of the Upper Rio Grande Water Operations Model (URGWOM) for this reach of the River. The primary product produced is graphic and tabular results of flood inundation limits for five distinct hydrologic conditions within the project study reach. The project includes computing tributary hydrology using HEC-HMS, FLO-2D data file development (channel file, levee file, hydraulic structures file), Hydrographic data collection (field surveys of over 100 cross sections), FLO-2D model compilation, FLO-2D model calibration, production of detailed CADD/GIS output, and report production.
